Abstract
Concussions and Traumatic Brain Injury (TBI) have become one of the most prevalent and
serious injuries a high school athlete can receive. Due to the potential long-term effects these
types of injuries have, there are now federal laws in place to help protect these athletes. This
theoretical paper will discuss the history of these laws and how the incidence of concussions has
been affected since enactment. Using data analysis from previous research, this paper will
attempt to answer the following research questions. First, has there been a reduction or increase
in concussion injuries since the laws have been enacted? And, secondly, has heightened
awareness caused students, parents, and coaches to be more cautious? Based on research
analysis, it can be concluded that heightened awareness has brought concussion injuries to the
forefront. However, it appears that because the new rules and regulations are present that forces
these types of injuries to be addressed, it seems that there have been more injuries since the laws
have been enacted than less. More longitudinal studies will need to be performed in order to get
accurate data.

I want to dedicate this project to my son, Joshua. I have watched you play football since you
were eight years old. You inspire me with your toughness and your tenacity and I am so proud
of you. I hope these laws will protect other young men from sustaining the life-long injuries that
those reflected in this paper have suffered.
I love you more than words.
To my husband, Robert, and daughter, Alyssa…thank you for enduring the long hours and for
giving me the time, space, and quiet needed to not only finish this project, but to see this degree
through to the end.
To my friends and colleagues, new and old, who have supported me, pushed me, and not allowed
me to give up. Your support means more than you will ever know!

Literature Review of Return-to-Play Laws and Their Effect on Concussion Rates for High School Football Athletes
Although concussions and traumatic brain injuries in athletes have occurred for centuries,
it seems to be more of a concern in recent years. In 2006, a series of events transpired which
changed how the nation looked at concussions and traumatic brain injuries. Before then, it
focused on professional athletes, but no real laws, rules, or regulations existed. As of 2014,
every state in the nation, as well as the District of Columbia, has enacted Return-to-Play laws to
help protect child, teenage, college-age, and adult athletes, specifically football players. These
laws focus on the diagnosis, treatment, and long-term effects of traumatic brain injuries and
involve the athlete, parents, coaches, and schools. This paper will discuss the definition of
concussion and traumatic brain injuries, history of nationwide concussion laws, and the effect
that those laws have had on the incidence of concussions on our child and teen athletes.
Background
The following section will discuss the background of concussions and the Return-to-Play
laws that have been developed to help protect our children from lifelong injuries. Concussions
among high school football players have the highest incidence nationwide. One family in the
state of Washington, the Lystedt family, watched their son suffer due to this type of injury. It
was because of their journey that laws have changed across the country.
According to the CDC, a concussion is a mild form of traumatic brain injury caused by
some sort of blow to the head or body which causes the brain to move back and forth, potentially
causing injury, within the skull. Athletes in contact sports, especially football, can have these
types of injuries at any time. The CDC reports that more than 3.5 million sports-related
concussions occur each year in the United States (2015). This number is alarming, considering
CONCUSSIONS 8
the recent passage of state laws to help protect these athletes. Symptoms of concussions are
wide-ranging from headaches and dizziness to memory loss and unconsciousness. These
symptoms vary due to many factors, such as the type of impact, history of previous concussions,
as well as treatment and recovery. Long-term effects also vary from motor deficits, memory
loss, and speech impediments to behavior problems, depression, suicide, stroke, and death. The
variance of long-term effects depend on the severity of the initial concussion, the number of
subsequent head injuries, and the length of time the brain was given to recover.
Zackery Lystedt
The history of concussion laws could not be discussed without knowing about the young
man the initial law revolved around. Zackery Lystedt was a healthy 13-year-old boy playing on
his 8th grade Washington State junior high football team. During one game in 2006, Zack was
injured when his head struck the ground after tackling an opponent. Zack was dizzy and
confused, so his coach had him sit out for several plays. Zack then went back in during the
second half of the football game where he got hit again. After the game, Zack collapsed on the
field, went unconscious, and had to be airlifted to a nearby trauma center for emergency life-
saving surgery to remove the right and left side of his skull in order to relieve the pressure from
his swelling brain (Centers for Disease Control).
During his recovery, Zack suffered numerous strokes, seven days on the ventilator and
three months in a coma before he awoke to his new life. Zack had a long road ahead of him as
he spent four weeks in a nursing home and two months in a children’s hospital for rehabilitation.
It was months before he could speak, stand, and perform normal activities like he had before.
Return-to-Play Laws
CONCUSSIONS 9
Before Zack’s injury, there were no laws in Washington that would prevent injured
athletes that were thought to have a concussion from returning to the game without receiving
medical clearance. There seemed, at the time, to be a lack of understanding of the severity these
injuries could have and a “be tough”, macho type of attitude. After Zack’s long recovery, he and
his parents began lobbying for a law that would keep others from going through what he and his
family had to undergo (Lueke, 2011). In 2009, Washington passed House Bill 1824, otherwise
known as the Zackery Lystedt Law, which requires clearance from a medical professional for
any athlete suspected of having a concussion injury before being allowed to return to games,
practices, and training.
Since the Zackery Lystedt Law was passed in the state of Washington in 2009, all 50
states in the nation as well as the District of Columbia have passed some sort of Return-to-Play
law, protecting those student athletes with concussive-type injuries. However, the laws and
requirements vary from state to state.
General Problem Statement
The general problem of this paper is to explain how state laws have affected the
incidence in sports-related concussions and TBI. Concussions are a nationwide problem for our
young athletes. According to the Centers for Disease Control and Prevention (CDC), over the
last 10 years, emergency room visits for sports-related traumatic brain injuries (TBI) and
concussions have increased by 62%. The risk of concussion is the highest for 15-19 year olds
nationally, regardless of gender. The CDC also reports that concussions can occur in any contact
sport, but have a higher prevalence in football and ice hockey (Centers for Disease Control,
2015). Concussions in professional athletes have caused an increased interest nationwide.
CONCUSSIONS 10
However, in recent years, there is now a growing emphasis on early identification and
management in young student athletes, yet limited information on treatment and recovery
(Darling, Freitas, & Leddy, 2015). When the brain is not given enough time to heal after a
concussion, dangerous and often life-altering symptoms may develop. Return-to-Play laws have
been enacted in all 50 states, but have they truly helped the incidence of concussions and TBI in
our youth athletes?
Specific Problem Statement
The specific problem of this paper is how Return-to-Play laws have affected the
incidence of concussions in high school football players. As of 2014, laws have been enacted
across the country regarding concussions and youth sports. Because the Zackery Lystedt Law
(WA House Bill 1824) was the first of its kind to be enacted by Washington State Governor
Christine Gregoire in May of 2009, this paper will focus on concussions and TBI amongst high
school football players in Washington State.
Purpose Statement
The purpose of this research is to determine whether a relationship exists between
Return-to-Play laws, Washington State specifically, and the incidence of traumatic brain injury
amongst high school football players.
Research Questions
This project aims to answer three main questions with regard to concussions and TBI
amongst high school football players. The research addressed the following research questions:
RQ1: How has the incidence of TBI amongst child and teen athletes been affected since
the Return-to-Play laws have been enacted?
CONCUSSIONS 11
RQ2: Has the heightened awareness over the past decade caused players and coaches to
be more cautious?
RQ3: What needs to be done to make laws more consistent and to reduce incidence of
concussions amongst student athletes even more?
Definition of Terms
CDC. CDC is an acronym which stands for The Centers for Disease Control and
Prevention. The CDC is the leading national public health institute of the United States. The
CDC is a federal agency under the Department of Health and Human Services and is
headquartered in Georgia.
Chronic Traumatic Encephalopathy. Chronic Traumatic Encephalopathy, or CTE, is a
form of encephalopathy that is a progressive degenerative disease, which can currently only be
definitively diagnosed postmortem. In March 2014, researchers announced the discovery of an
exosome particle created by the brain which has been shown to contain trace proteins indicating
the presence of the disease.
Concussion. A concussion is a type of traumatic brain injury—or TBI—caused by a
bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move
rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in
the skull, stretching and damaging the brain cells and creating chemical changes in the brain
(Centers for Disease Control and Prevention, 2015).
Encephalopathy. Encephalopathy is a general term that describes a disease or disease
process that affects the function or structure of your brain.
National Football League. The National Football League, shortened to the NFL, is a
professional American football league, consisting of 32 teams, divided equally between the
CONCUSSIONS 12
National Football Conference (NFC) and the American Football Conference (AFC). The NFL
has made huge strides in supporting laws and financing research regarding traumatic brain injury
in not only their players, but as role models for younger athletes.
Return-to-Play laws. These laws, started with the Zackery Lystedt Law in Washington
State in 2009, have now been enacted in all 50 states and the District of Columbia. These laws
set up specific requirements for athletes deemed to have a concussive injury in order for them to
return to any type of training, practice, or game.
TBI. Traumatic brain injury or TBI is caused by a bump, blow or jolt to the head or a
penetrating head injury that disrupts the normal function of the brain. The severity of a TBI may
range from “mild (a brief change in mental status or consciousness) to “severe,” (an extended
period of unconsciousness or amnesia after the injury) (Centers for Disease Control and
Prevention, 2015).
Literature Review
This section will discuss a review of current literature on the subject of concussions.
Although, there are many topics to compare and analyze, only three will be discussed here. The
first concept will be centered on how the state laws came to be regarding concussions and
athletes, particularly high school athletes. The second concept will discuss how coaches have
had to adopt new practices into their routines when dealing with concussive injuries. Finally, the
research will show that there are many gaps in the literature where future research is needed in
order to determine if the laws have helped or hindered these student athletes, their families, their
coaches, their teams, and their communities.
CONCUSSIONS 13
Overview of State Laws Surrounding Concussion Injuries.
As was discussed previously, Return-to-Play laws came into the nation’s consciousness
because of a brave young man from Washington and his family. After seeing what their son
had to endure, the Lystedt family decided to take action and force lawmakers to look at the
current laws in order to make a change. Before this law was in place, there was a lack of
understanding and awareness regarding the effects that concussive injuries could have (Hodge &
Kadoo, 2014). Washington’s House Bill 1824, otherwise known as the Zackery Lystedt Law
was enacted in 2009 and was the first of its kind. This original law had specific guidelines for
players, parents, coaches and other school officials, as well as physicians and treating facilities.
The original Lystedt law had several components. First, if a concussive injury is
suspected, the athlete must be removed from play, whether a game situation or practice
(Foreman, 2010). Secondly, the athlete must then be evaluated and cleared by a licensed health
care professional that is specially trained to assess head injuries before being able to return to
play. This could be a physician, athletic trainer, or other professional who has received the
necessary training (Schwartz, 2013). Finally, education and training of schools, coaches,
parents, and players must take place to improve awareness and increase the likelihood of
noticing signs and symptoms of head injuries.
The Lystedt Law, with the support of the National Football League and other influential
stakeholders, set a precedence spurned change across the nation. By 2014, there was some form
of a Return-to-Play law in every state in the nation and the District of Columbia. Each state has
some variation of these two basic concepts, but all have some combination of the following
rules: mandatory removal of play; mandatory bench times; required medical clearance; required
CONCUSSIONS 14
training and education for coaches, parents, and athletes; and informed consent of athletes and
their parents (Centers for Disease Control, 2015).
The thought behind the laws were to reduce intensity of the injury, by removing the
affected athlete and prevent further injury from occurring. Although it could never be proven,
health care professionals and lawmakers agree that if there was a law like this one in place prior
to Lystedt’s injury, he may have not suffered the irreversible damage that he currently has. The
Centers for Disease Control have also taken up the Head’s Up campaign to assist schools,
coaches, parents, and players with understanding the reasoning behind these rules and
regulations (Centers for Disease Control and Prevention, 2015).
This seems like a simple concept to grasp, but the literature has shown that there are more
issues with this simple act than first realized. In a research study by Lowrey & Morain,
interviews were conducted in 35 of the 42 states that had enacted laws as of 2012. These
informants were chosen to be representatives of the organizations and agencies responsible for
implementation of their state’s concussion law. Results from this study showed many issues
with having such a variation in the laws. There were many states that were uncertain in defining
which individuals and activities the law should cover. For example, what age groups does the
term “youth athlete” include? Is an 18 year old who is still in high school still considered a
youth athlete, or are they now considered adult? If an 18 year old is indeed covered, then these
laws may need to be extended to include collegiate athletes as well (Andrews, 2013).
There were two main issues that were concluded by Lowery & Morain (2014):
ambiguous definitions and an unclear assignment of power. An ongoing concern for many states
is trying to conclude which providers are adept in making Return-to-Play assessments. This
study also found that there is no consistency in enforcement in order to ensure that these rules
CONCUSSIONS 15
and regulations are being followed. Some states have gone so far as to impose penalties on
schools, coaches, and athletes if they are non-compliant. The informants indicated that there
were three overall barriers to compliance with these state laws. Provider access, especially in
rural areas was one of the biggest hurdles. There has been some concern amongst legislators,
sports administrators, and others that compliance to these laws in rural areas may prove difficult
without the appropriation of resources (Faure, Moffitt, & Schiess, 2015). Finding appropriately
trained medical personnel to evaluate and treat the student athletes can be extremely difficult.
Secondly, parental involvement was a large concern. Those interviewed indicated many parents
shopped around for practitioners until they found one that would clear their child, whether they
were healthy enough to play or not. Finally, general awareness of the laws themselves was a key
factor (Lowrey & Morain, 2014).
In 2013, Hosea Harvey conducted a research review on every state that had a sports TBI
law enacted between 2009 and 2012. Harvey (2013) conducted a comprehensive survey and
found, at the time of the study, 44 states and Washington D.C. had enacted one or more youth
sports TBI laws. At the time, there were 6 states that had no such law, but we know now that
during the 2 years following, the remaining states also enacted their version of a Return-to-Play
law (Refer to table in Appendix 1). Of the 44 states with laws, 41 of those as well as
Washington D.C. require coaches to remove athletes from play if they were suspected to have
TBI. All of those, with the exception of Wisconsin and Ohio required a minimum of 24 hours
for a player to sit out. Only Delaware mandated a removal of greater than 24 hours (Harvey,
2013). Harvey’s study also found that an athlete must be cleared by a third party in 40 of the
states and Washington D.C. There are several different categories that a health care professional
could fall into. Permitted roles include certified athletic trainer, physician, physician trained in
CONCUSSIONS 16
concussion management, health professional certified with experience in concussion
management, nurse, or neuropsychologist. Harvey found no consensus as to which health care
professional was better equipped to evaluate these young athletes across the states. Another
interesting finding was that amongst the states that require medical clearance by a health care
professional, only 26 of the 45 jurisdictions require that the practitioner be trained in TBI
assessment and management (Harvey, 2013). Informed consent was the third most common
element in the provisions found during this study. 34 of the 45 jurisdictions hand out
information to parents and players about concussions most require a parent and student signature.
The information dispersed varied from state to state, however the CDC’s widely circulated
material was mentioned in several of the state’s regulations.
In a third study by Gibson, Herring, Kutcher, and Broglio (2015), a different approach
was undertaken. This study involved analyzing insurance claims for TBI to evaluate whether
there has been an increased prevalence in concussions and head injuries occurring since the laws
have been enacted. This study attempted to analyze health care utilization rates for concussions
from 2006 to 2012. There were two main research questions posed for the study. First, due to
mandatory removal from play and requiring medical clearance before returning, would fewer
cases be reported because athletes may want to hide their symptoms in order to continue
playing? Secondly, have the concussion laws led to an increased interaction between athletes
and medical professionals for injury diagnosis or clearance to return to play? (Gibson, Herring,
Kutcher, & Broglio, 2015). Gibson et al., (2015) studied children ranging in age from age 12-
18, the age group most likely to be affected by concussion legislation. The results of this study
indicated a 92% increase in health care utilization in states that had concussion laws in effect
between the 2008-2012 school years. In states without concussion legislation, there was still a
CONCUSSIONS 17
75% increase in the identification and treatment of concussion (Gibson, Herring, Kutcher, &
Broglio, 2015). The increased media coverage as well as National Football League and CDC
involvement may have had something to do with the increase nationwide, whether a state had a
law in effect or not. This poses another question: Do the laws themselves have an impact on
health care utilization for concussions or are we as a country and society just more aware of the
problem?
Overview of Coaches Involvement in Concussion Regulation
The second concept to be discussed is how concussion legislation has affected coaches,
as well as schools and communities. As discussed earlier, when Zackery Lystedt was lying on
his back holding his helmet, the coach pulled him from the game. He sat out for three plays
before his coach allowed Lystedt to return to the game. It is unclear if this was strictly the
coach’s decision, whether he was feeling pressure from Lystedt’s family and the other fans, or
whether Lystedt was begging him to return to the game. The general public may never know
what the exact scenario was. What is known is that coaches all across the country have a huge
responsibility to not only teach our children how to play the game, but to keep them safe from
injury. As parents, one would cling to the idea that our child’s coach truly wants to do the right
thing. Parents trust them that when our child is on the football field, that coach knows what he
or she is doing and has had the necessary training to recognize injuries when they occur.
So, now that there are concussion laws nationwide, what exactly is the coach’s
responsibility? One of the key components present in almost all of the state concussion laws
include training of coaching staff to not only recognize early signs of TBI, but also how to
manage those players already injured. Harvey (2013) found that only 25 of the states with
concussion legislation actually had explicit coach education guidelines. Most of these programs
CONCUSSIONS 18
included symptom recognition, but the training requirements ranged from annually to every few
years. Only a few of the states had general guidelines for what was included in coaching
training, and none of them indicated who was responsible for providing the training. Although
guidelines can be vague, some voluntary membership associations require a more vigorous
training than the state or school boards require, meeting this requirement for the state laws.
With enactment of concussion legislation still being fairly new, the last state law was just
enacted last year; implementation has been found to be limited. This means that many coaches,
even those who are active in states with concussion laws, may receive inconsistent and limited
education and training. Covassin, Elbin, and Sarmiento (2012) found that only 61% of coaches
could correctly identify the signs and symptoms of concussive injury. This number does not
indicate that appropriate education is being performed despite numerous educational materials
being available to coaches at the high school level.
Many educational materials are present in the form of educational videos, posters, fact
sheets and web sites (Covassin, Elbin, & Sarmiento, 2012). A study of New England high
school coaches indicated that 80% of coaches in the area found the educational materials
provided to at least be moderately helpful in recognizing the signs of concussion, how to prevent
further injury from occurring and how to respond should an injury occurs (Guilmette, Malia, &
McQuiggan, 2007).
After the Lystedt Law was enacted in Washington and subsequent states followed suit,
the CDC initiated the “Head’s Up: Concussion in Youth Sports” campaign in 2007. The goal of
this initiative was to provide education to sports coaches on prevention, recognition, and
response to sports-related concussion. The website offers a variety of educational opportunities
including: a free online training course, fact sheet, customizable action plan, concussion facts
CONCUSSIONS 19
and contact numbers, main message poster, signs and symptoms poster, fact sheet for coaches,
clipboard concussion information sheet and sticker (refer to Appendix 2), and concussion poster
(Centers for Disease Control and Prevention, 2015). During the course of the study, Covassin et
al., (2012) indicated that the CDC’s materials were found to be the most useful source of
information among high school football coaches. After being properly educated, such as after
utilizing the Heads Up materials, many coaches have felt that they learned something new
regarding concussion recognition, treatment, and prevention.
Many states have opted to incorporate concussion training into their already existing
coach education. The state of California, for example, has incorporated “Chapter 173” into their
pre-existing guideline. Chapter 173 requires CPR and first-aid training for all high school
coaches to include a basic understanding of the signs and symptoms of concussions and the
appropriate response when concussive-injury occurs (Hunsucker, 2013). This allows for
consistent training across the entire state and poses another question. If we want to decrease
incidence of concussions, prevent further injuries from occurring, and expect coaching staff to
have the proper training and education, then why are there not consistent and mandatory
guidelines nationwide?
The answer to that question may not appear for many more years. However, as the
incidence of head injuries in student athletes continues to rise, lawmakers are realizing the
importance of consistent and regulated guidelines. As of 2010, only 5 states: Connecticut, Idaho,
Oregon, Texas, and Washington have passed laws to establish minimum concussion education or
management guidelines. Other states have begun to get on board, such as New Jersey.
Representative William Pascrell (D-NJ) has attempted to amend Title III of the Public Health
Service Act for many years (Faure, 2010). His bill, “Concussion Treatment and Care Tools Act”
CONCUSSIONS 20
would establish and implement national concussion management guidelines for children ages 5-
18.
These studies and other literature have cemented the idea that proper training and
education of coaches are a necessity when concussed athletes are in their care. There are times
when athletes will hide their injuries because they want to play. An anonymous online survey
described in Neurology Clinical Practice indicated that 43% of the 262 collegiate athlete
respondents with a history of concussion said they had hid symptoms in order to continue
playing (Schwartz, 2013). They may downplay their symptoms so as not to disappoint their
coaches, their parents, or themselves. Younger athletes don’t understand or realize the long-term
effects of these types of injuries. Adolescents who have already suffered TBI have an increased
incidence of sustaining another injury at some point in their lifetimes (Guskiewicz, 2015).
Research has shown that child and adolescent brains take longer to recover than adult brains
(Faure, 2010), which makes it even more important to make sure that the guidelines are
followed. Young athletes, who just feel a little dizzy may opt to go back in because their team
needs them, not realizing they may be suffering a serious brain injury leading to permanent brain
damage or even death (Tarshis, 2011).
This is the time when coaches need to be proactive, assess their players, rely on their
training, and follow the guidelines laid out for them. First and foremost, coaches are there to
teach their players proper technique. In the game of football, learning how to tackle and how to
be tackled to prevent injury is the key. The proper use and care of equipment is also essential in
preventing injury. Having a routine in place to check equipment such as helmets and pads
regularly and having a policy in place when equipment needs repair will go a long way.
However, no matter how trained the athlete is, accidents will happen. It becomes the state’s, the
CONCUSSIONS 21
community’s, the school’s, the parent’s, the coach’s, and the athlete’s responsibility to ensure
protocols are followed, and when an injury does occur, that the correct steps are taken in order to
prevent further injury from happening. So education for coaches only does not seem to be
enough. There needs to be regular training to all of those involved from lawmakers to the
players themselves in order to fully understand current rules and regulations.
Future Research and Literature Gaps
This section will discuss the future of research linked with sports-related concussions and
gaps in the literature on this subject. To date, research has primarily focused on defining
concussions and traumatic brain injury (TBI). Definitions, causes, long-term effects, prevention
strategies, and management techniques have all been discussed over and over again. There have
been many research studies focusing on state laws, the differences and variances between states,
and what individual states are doing to strengthen their concussion guidelines. Because the
interest and focus has only been present seriously for the past decade, little research has been
completed regarding how we as a country are doing. Have the laws really helped to decrease
incidence of concussions in high school football players or are we becoming more aware?
Concussive injuries are not new; in fact, concussions have been known about for
centuries. However, with the NFL making these types of TBI more in the forefront and cases
such as Zackery Lystedt making national news, we as a society are more aware of what
concussions look like, what the long-term effects are, and what we can do to better prevent them
from occurring. Much remains unknown, however, about the long-term effects concussions can
have, especially on our youth athletes.
Erdtmann (2015) discusses the lack of data regarding the overall incidence in sports-
related concussions, particularly in youth athletes. Due to the Return-to-Play laws and
CONCUSSIONS 22
guidelines requiring education and training, there is more of an awareness regarding concussions
and a better recognition of symptoms (Erdtmann, 2015; Noble & Hesdorffer, 2013). Recently,
the Institute of Medicine and the National Research Council, as well as numerous government
agencies and private groups assembled an expert committee to examine the logistics behind
sports-related head injuries and how it relates to our school-age and adolescent populations. This
committee called on the CDC to begin collecting data which would help determine the incidence
of concussions. Many factors would need to be taken into account such as demographics, sports
equipment used, history of previous concussions; as well as the cause, nature, and extent of the
injury and signs and symptoms observed (Chrisman et al., 2013; Erdtmann, 2015).
Another area for future research would be studies on the physiologic changes in the brain
chemistry when concussions occur in young athletes (Noble & Hesdorffer, 2013; Semple et al.,
2015). Also needed are studies that discuss the impact that repetitive injuries have on the brain
and what long-term effects that can incur. We have seen the damage that happens with
professional football players, hockey players, and boxers in the media. The symptoms range
from depression, garbled speech, and slower cognition to mental retardation, and even suicide.
However, more studies are needed to discuss scientifically what happens to the brain itself when
repetitive injuries happen (Erdtmann, 2015). McKee et al. (2013) performed an analysis of
postmortem brains to attempt to identify patterns of brain injury amongst former athletes,
military veterans, and civilians. That study included football players in the athlete group and
was divided into age ranges. The results of this study indicated that although professional
athletes make up the majority of CTE cases, high school football players also could be diagnosed
with the disease, even with their limited TBI exposure. Although most high school subjects were
diagnosed 20 or more years after their athletic careers were over, there were a handful of cases of
CONCUSSIONS 23
high school players who died prior to age 20 (Maroon, et al., 2015). These results indicate that
trauma to a young brain can be even more dangerous than to an adult.
Little has been discussed regarding sports equipment, especially helmet design. If we
want to protect the brain from jarring injuries, adequate helmet protection should be number one
on the priority list. The current design of football helmets yields a rigid exterior with a padded
interior, intended to protect the head from impact. Many football players, especially young
athletes who have not yet been adequately trained, are inclined to lead with their heads as an
offensive play, validating their actions with the premise that their heads are protected (Noble &
Hesdorffer, 2013). This change to a harder helmet in order to protect heads from injury may
actually have a negative effect; encouraging players to hit with their heads (Nakatsuka &
Yamamoto, 2014). More research is needed to assess whether the current football helmet design
is protecting the heads of our student athletes or causing them more harm.
One major hurdle when discussing current concussion guidelines is which one to follow.
For adult sports, there are 16 different concussion-related guidelines. These range from simple
monitoring of the athlete to much more strict and rigorous routines. This makes standardizing
treatment extremely difficult. The guiding principle of the rules is that any athlete remaining
symptom-free for seven days and does not demonstrate any remaining neurologic deficits may be
allowed to return to the field and participate again (Hodge & Kadoo, 2014). There are no
standardized grades and testing for concussions. Each guideline also has varying requirements
as to when an athlete can return to play. Hodge and Kadoo (2014) indicate that a more uniform
management system would better serve the needs of the athletes, take pressure off of the coaches
and health care professionals caring for them, and are able to track these cases much more
fluidly. Having systematized statewide efforts aimed at concussion education, management, and
CONCUSSIONS 24
prevention is needed in order to identify, prevent, and maximize recovery of sports-related
concussion injuries (Conder & Conder, 2015).
Method
This section will discuss the effect that Return-to-Play laws have had on concussion rates
in high school football players. Over the past decade, many research studies have been
completed looking at how these rates have increased and the potential causes. It appears that the
rates have risen vastly, but the question remains: what is the cause? This section will break
down the populations studied, what type of research was completed, and how data was collected
and analyzed.
Research Method and Design Appropriateness
In studying the effect of Return-to-Play laws on the incidence of concussions in student
athletes, there are many avenues to take. Due to the newness of the laws (the final states with
enacted laws only came into effect last year), there is very little raw data. Also, because the laws
vary state to state in their wording and descriptions as well as their inclusions of factors, it would
prove difficult to perform a quantitative study at this point in time. However, using medical
coding and insurance claims data, it would be possible to perform this type of statistical research
in the upcoming years, when there is data available to compare.
The CDC estimates that between 1.6 million and 3.8 million concussions occur in sports
or recreational activities annually (Dompler, et al., 2015). However, this number is largely
inaccurate. There are numerous reasons this injury is underreported. First, if the injury is mild,
many players do not seek medical attention. Without being officially reported, the CDC is
unable to include these athletes in their overall total numbers. Secondly, as discussed in the
literature review, many athletes and parents “shop around” to find the right health care
CONCUSSIONS 25
professional that will clear the athlete in order to return to play faster. This phenomenon skews
the data. Finally, the varying degrees of concussions including location of impact, symptoms
involved, and recovery time, makes comparisons difficult. This quantitative approach to
analyzing the numerical and statistical incidence in concussion rates may not provide an accurate
reporting of the data for years to come.
For the purposes of this paper, a qualitative approach was taken. Using and comparing
previous research as well as current trends by continuously asking the question “why?” is how
this reviewer will attempt to get to the cause of the increased incidence in concussions amongst
high school football players. Qualitative research involves exploration and description in order
to find meaning in specified social settings (Forister & Blessing, 2016). This paper focused on
the literature already surrounding the topic of concussions in athletes, incorporating findings
from other researchers, provide areas for future research, and attempt to determine whether these
new laws have made a difference in rates of concussions.
This descriptive research project compared available literature on concussions and
focused on those that discussed incidence, state laws, and future research opportunities on the
topic of high school athletes. Data comparisons, analysis, and results were compared to
determine if there was a common theme regarding recent concussive injuries.
Population
The study population for this project involves high school football players who have
suffered a concussive-type injury during the course of a game or practice. During the course of
the research, it was determined that one cannot discuss this younger group without first
incorporating cases from the National Football League. Numerous retired NFL players have
been diagnosed with brain disease resulting from concussions they received while they were
CONCUSSIONS 26
playing football (Tarshis, 2011). Research has shown that these professional athletes have
suffered memory loss, blurred vision, chronic headaches, dementia, and depression all making up
a rather new diagnosis of chronic traumatic encephalopathy (CTE), a degenerative disease
involving repeated head trauma.
A few cases to point out would be that of Jovan Belcher, Junior Seau, and Mike Webster;
all who suffered chronic traumatic encephalopathy, ultimately resulting in their deaths. Belcher,
a Kansas City Chiefs linebacker shot and killed himself after killing his girlfriend. Pathology
after his death confirmed he suffered from repeated head trauma resulting in CTE. Junior Seau,
retired New England Patriots linebacker, suffered depression and ultimately took his own life at
the age of 43, where testing also confirmed CTE (Drysdale, 2013). Finally, Mike Webster,
veteran center for the Pittsburgh Steelers suffered from amnesia, depression, and dementia after
his 17 years in the league. He was the first confirmed diagnosis of CTE, spurring the NFL to
make changes to their policies, procedures, and definitions of concussions. His case inspired
more research to be done, better ways to protect these athletes, and have even inspired a new
movie which premiered on Christmas Day 2015, starring Will Smith and entitled “Concussion”
(See Appendix 3).
Because of the studies stemming from the deaths of these elite athletes and the findings
of CTE, the NFL has made drastic changes in how they are attempting to protect their players.
For example, the NFL has changed the length of kickoffs, enforced new rules to limit head and
neck contact with defenseless players, and have now required consultation with a neurologist if a
concussion is suspected (Drysdale, 2013). The NFL has also donated millions of dollars to fund
research surrounding TBI and the connections between concussions and long-term brain disease
(Tarshis, 2011).
CONCUSSIONS 27
Sampling Frame
With the changes the NFL has made, also brings the responsibility to mold and
shape younger football players as well. The NFL has served as role models to young athletes on
many levels. Now, due to the changes the NFL has made as well as organizations like the
CDC’s Heads Up campaign, regulations in collegiate and high school sports programs have been
altered as well. Taking the professional NFL athletes into account, this paper utilized a stratified
purposeful sampling strategy aimed to focus on high school football players as the subgroup of
the overall population. The Zackery Lystedt Law in the state of Washington caused a ripple
effect across the country, initiating Return-to-Play laws being enacted in every state in the nation
and Washington D.C. by 2014. This paper attempted to narrow the sampling down even more
by focusing specifically on how the Washington state law affected incidence in student athletes
of that state. This proved difficult, however, due to limited research available. One study
actually focused on that population, finding that there indeed was an increased incidence in
concussive injuries post-Lystedt Law initiation (Bompadre, et al., 2014). There were, however,
many limitations mostly due to lack of data.
Data Collection
For this qualitative research project, data was collected utilizing scholarly articles and
periodicals, as well as peer-reviewed sources. Websites such as Google Scholar and Kaplan
University Online Library were used in order to search for relevant resources. Search terms such
as “concussions in high school football players”, “traumatic brain injury in football players”,
“state laws on concussion”, and “concussion in student athletes” were used. These articles were
read, and sorted by topic such as state laws, coaches’ perspectives, and concussions in order to
organize the outline of the paper as well as attempt to answer the research question. Content
CONCUSSIONS 28
analysis was performed by narrowing down the main topics in order to create categories and
define the theme of this paper (Forister & Blessing, 2016). Sources were united and sectioned so
that the main research questions were covered and a final theme revealed.
Data Analysis
Data analysis was achieved after articles were read and carefully sorted into the main
topics. Attempts were made to incorporate literature that supported this reviewer’s thoughts and
ideas as well as those that disagreed in order to bring both sides to light. Research that had
similar conclusions was combined to form cohesive answers to the research questions. Many
studies indicated the need for future research and these were also combined. Research that did
not fit into the created outline was then discarded so as to keep this paper from being too broad
and disjointed. Once all research was organized, sorted, and outlined, a final formulation was
attained and generalizations were made.
Findings
The purpose of this paper was to discuss the Return-to-Play laws and how the incidence
of sports-related concussions in high school football players has changed since enactment.
Previous research has shown that there has been an increase in concussive injuries. The
following section will discuss the implications of the research conducted, limitations of the
research, and recommendations for future study.
This project predicted that the incidence of concussive injuries in high school football
players would increase after the Return-to-Play laws were in effect nationwide. This theory
proved true after a literature review. The reasons why, however, remain alarming, implicating
that much more research needs to be done on the topic. There were several theories as to why
CONCUSSIONS 29
concussions have risen steadily since 2009 when the Lystedt Law was enacted in Washington in
2009, however the main reason that frequented the literature was an increased awareness about
the diagnosis, new rules and regulations surrounding concussions, and how to prevent future
injuries from occurring.
Rise in Awareness
Since the first Return-to-Play law went into effect in Washington, all the other states in
the nation as well as Washington D.C. have legislated similar laws to help protect these student
athletes from irreparable harm. With backing from the NFL and the CDC, as well as other
groups and organizations, concussions have become a primary focus on the football field
amongst coaches, players, and parents alike. The NFL has made major changes in the past
decade to reduce the incidence of concussions. The organization has enacted their own rules and
regulations as well as contributed to scientific research studying the cause of long-term effects on
concussive injuries on brain function. The CDC has created the Heads Up campaign which has
educational and informative resources for coaches, parents, and athletes.
With all of the media reports circling around concussions as well as state legislation, it is
no wonder that communities are more aware of concussions and that the incidence has increased.
The majority of the literature points to an overall increase in the rates of concussions since the
Return-to-Play laws have been enacted. Gibson et al. (2015) reports a 92% rise in health care
utilization in states with concussion laws in effect during the 2008-2012 school years. Even
those states with no law yet enacted during that time had an increase in reported concussive
diagnoses among young athletes. However, the question still remains, are there truly more
concussions or are there just more reported due to rules, regulations, and reporting requirements?
CONCUSSIONS 30
In fact, some may argue that the United States, as a country, are too aware. The term
concussion has become such the focus in recent years that people no longer think of the term
itself and what it entails. Because the symptomatology differs between patients and often are
undetected on imaging, these types of injuries are often brushed off (Stephenson, 2014). As
stated earlier, many athletes falsify symptoms just so they can go back in and play. As a society,
communities are very aware of those patients who have long-term brain damage, those in comas,
and those who have committed violent acts against themselves or others. What must be
remembered is that the minor injuries can affect young athletes, just as much, especially when
repeated injury occurs and the brain is not given enough time to recover. Has awareness done
more harm than good when it comes to recognizing, treating, and preventing concussive injuries
in our young athletes?
Limitations
Being more aware is always a positive trait to have. But, has improved awareness
improved the long-term effects of concussions? And, has being more aware been able to prevent
further injuries from occurring? The study of traumatic brain injury in football players is multi-
faceted as there are multiple factors playing into the diagnosis, treatment, prevention, and
education. These factors can lead researchers on wild goose chases looking for a particular
answer, where one answer does not exist. This paper attempted to narrow down the focus to
discuss the Return-to-Play laws themselves and their impact on concussions in high school
football players. Even with those specific topics, it was difficult to not bring in stories and
research surrounding professional athletes as well as physiologic and anatomical discussions
regarding the injuries themselves.
CONCUSSIONS 31
The first limitation to this study was the variances in state laws. The difference between
state laws made it difficult to compare apples to apples. For example, as previously stated, a
large number of states used vague terminology making it easy for alternative interpretation of the
laws themselves (Harvey, 2013). Some states require an athlete to be assessed by a physician,
while others only require evaluation by a school nurse or athletic trainer. This can cause a
discrepancy between who diagnoses an actual concussion and who does not, based on education
and training.
Other limitations include the population itself. The initial population was football players
in general. The sample was framed to specifically discuss high school athletes. Much of the
research reviewed did discuss high school athletes, however not just football players. Many of
the researchers also discussed athletes who participate in other sports such as rugby, soccer,
wrestling, and basketball. Also, this paper focused on football players, but did not specify
gender. It was assumed that the literature would focus on high school boys, since that is the
major group that participates in this particular sport. However, there are a number of girls that
play football and more are joining their junior high and high school teams every year. The
literature also discussed the increased incidence of concussions among female athletes, which
was not reviewed for this paper.
Finally, time provided a major constraint when performing literature review on this topic.
The Return-to-Play laws are still only a few years old. There is very limited data available to
truly compare pre-law rates versus post-enactment rates of concussion. As the CDC continues to
collect data and progresses their Heads Up campaign, it will be easier to determine causality of
the injuries, age ranges, which sports had the higher incidence, how long the athlete was
removed from play, and what the long-term effects of the injuries are.
CONCUSSIONS 32
Use and Application of Findings
The use and application of these findings may contribute to future research on
concussions in high school football players by incorporating what we know today and what we
need to know for the future. Since Zackery Lystedt and his family so bravely fought for a state
law to help other athletes from suffering the brain damage he has incurred, every state in the
nation has enacted some form of a Return-to-Play law. The basic premise of these laws is if a
player is suspected of having a concussion, they are immediately removed from play. That
player must then be evaluated by a trained professional and cleared prior to coming back and the
coaching staff must go through a specific concussion-related training. The problem with
researching if these laws have had an effect on concussions in this population is that there are so
many different interpretations of the law. The basic concepts are concrete; however the wording
regarding the degree of concussion and who needs to evaluate the athlete has come into question.
There is more awareness of TBI suffered by athletes than there was even ten years ago.
However, there is so much more that needs to be known in order to help young athletes from
suffering permanent damage. By using the guidelines set forward by the NFL and the CDC, the
following recommendations for future research could improve recognition and diagnosis,
treatment, and recovery of sports-related concussions in high school football players.
Recommendation: There should be a national protocol to assist states and schools with
concussions.
The research has shown that due to the differences between state laws, it is difficult to
have consistent data to compare state incidences of concussions among student athletes. If every
state had the same rules, the same education and training for parents, coaches, and kids, and the
same consequences for a breakdown in these rules, it would be much easier to analyze data.
CONCUSSIONS 33
Some states have minimal time an athlete must be out before returning to play, while others are
much stricter. Most states have minimal basic training for coaching staff, while others have
much more in-depth education. Also, very few states actually have consequences for schools,
coaches, or athletes for breaking these rules. If these were the same across the board, everyone
involved would know what the rules are. All coaches would be required to participate in
mandatory training regarding concussions including the most up-to-date regulations. The
problem with this recommendation is that there are many more opportunities for schools in urban
communities. In more rural areas, it may prove difficult with funding and opportunities to
provide these necessary services. Also, research has shown that finding qualified health care
professionals to evaluate these athletes in the timeframe allotted can be difficult. All in all, the
rules need to become more consistent in order for research to progress.
Recommendation: Longitudinal studies need to be performed to evaluate the effects of
head injuries in student athletes over time.
Many studies have been done on the effects of TBI on professional athletes, such as those
in the NFL. However, very few have been accomplished on the long-term effects on young
athletes. Researchers have indicated that younger brains heal much differently than adult brains
and that repeated trauma to a young brain can have devastating long-term effects. Further
research needs to be performed to understand the adolescent brain and the consequences of
multiple concussions on growth and development on this still growing vital organ. It is known
that adult TBI can cause memory loss, depression, speech difficulties, and progress to brain
damage and even death. It is also known that the more repetitive injuries an athlete suffers, the
more damage can be done, often irreversible. Research has been conducted on CTE in adults,
however less has been shown regarding if there are similar diagnoses for young athletes. With
CONCUSSIONS 34
the newer Return-to-Play laws, knowledge about these effects on younger brains can aid in
development of better and safer equipment. It can aid lawmakers in updating and renewing
these laws to help protect these young people.
Recommendation: Parents and students need more education on concussion and traumatic
brain injuries.
Part of the Return-to-Play laws is a specific component referring to education and
training. This element primarily referred to coaching staff. However, in order to truly inform
everyone involved. Mandatory education should be available to parents and players as well.
Currently, most parents sign a piece of paper saying they read the concussion policy. Most
parents, when asked, rarely read this form. Having parents and students sign a form may help to
meet the liability that schools incur. However, it does little to really educate those signing about
what concussions are and the protocols in place. Information regarding their child’s health
should be available to parents. This would not be in the same form that it is to coaches. One
way this could be achieved is at parent night for any contact sports. A short public service
announcement by former NFL players, coaches, athletic trainers, etc. could be shown in the form
of a video. This PSA could describe symptoms and long term effects as well as what the
necessary steps are that would be taken in the event that a concussive injury occurred. The
parents and players would then sign that they had watched the PSA. The CDC also provides
information for athletes and their parents, however if they are unaware that the information
exists, they more than likely would not voluntarily go there to look for it. Players need to know
what could happen to them if they continue to play with head injuries and what will be expected
of them if they show signs and symptoms.
CONCUSSIONS 35
Conclusion
This capstone project focused on concussion injuries in high school athletes, primarily
football players. The NFL has been funding research to get to the bottom of traumatic brain
injuries for many years. However, it has only been recently that laws have been put in place for
our younger players. The Lystedt Law from Washington State set the ball rolling after a young
player suffered lifetime injuries after repetitive head injuries during a junior high football game.
It was because of this boy and his courageous family that there are now nationwide Return-to-
Play laws.
The purpose of this paper was to answer several research questions. First, how has the
incidence of concussive injuries changed since the enactment of these laws? Secondly, has
heightened awareness caused coaches, parents, and athletes to be more cautious? And finally,
what needs to be done to make laws more consistent and to reduce incidence of concussions
amongst student athletes?
To answer these questions, a qualitative literature review was performed. These state
laws are still fairly new, however many studies have already occurred. Research has shown that
the incidence has steeply risen over the past decade for many reasons. The primary reason found
in the literature is that there is a heightened awareness of these types of injuries. Many
professional football players have been in the media who have suffered from long-term effects of
injuries, some ultimately succumbing to their injuries. There is even a recent movie that has
come out discussing some of these players and the research that has occurred. The Return-to-
Play laws are in every state and have rules for every high school player. Coaches, parents, and
athletes are more aware, but these laws vary statewide and have differing interpretations, thus
making consistency difficult.
CONCUSSIONS 36
Because of the newness of these laws and the lack of comparable data, future research is
necessary to truly make a difference in the incidence of concussions. The biggest gap in the
literature involves the study of the adolescent brain and what the long-term effects of repetitive
injuries have been. The diagnosis of CTE has been determined postmortem on numerous
professional athletes, however very few studies have been performed to determine long-term
effects on young athletes. Longitudinal studies are needed in order to conclude the best way to
protect these young brains from long-term harm.
Based on this literature review, several recommendations were made. First, due to the
variance in state law requirements, there needs to be a nationwide consistent policy in place. It
shouldn’t matter if you are living on the west coast, east coast, north or south; if a high school
athlete suffers from a head injury, there should be consistent protocols in place. There should be
clear definitions of what concussions are, who evaluates and treats the athlete, and how long the
player remains out of play. To date, these factors vary greatly, not only making data mining and
analysis difficult, but potentially causing harm to these young people.
Secondly, it was recommended that consistent education and training needs to occur.
Coaches should all have to have the same education and training when it comes to traumatic
brain injury. They should know how to recognize signs and symptoms, what steps need to be
taken in order to get that player healthy again, and what the consequences will be if those rules
aren’t followed. Currently, state laws fluctuate immensely with regard to coach education and
concussions. This recommendation also applies to education to parents and players as well.
There should be mandatory education for all players and parents at the beginning of every sports
season. This reviewer indicated a public service announcement in the form of a video featuring
NFL players, leading researchers, athletic trainers and coaches may get players’ attention, so
CONCUSSIONS 37
they take the information seriously. Those involved need to understand the importance of the
protocols and not just look at it as another form that needs signed. It needs to be taken more
seriously.
In conclusion, concussions are one of the most prevalent and damaging injuries a high
school football player can face. There have been great strides over the past decade to help
safeguard our adolescent athletes from harm. However, so much more can be done. These
future players are our future, and we must protect them as parents, as coaches, as communities,
and as a nation.
