WSYBCSU Evidence briefing 2014
Int roduction
There is a substantial body of evidence that clearly
demonstrates that tailored physical exercise programmes
are highly effective in reducing risk and rate of falls in older
adults (aged 65+). The aim of this document is to provide a
balanced overview, synthesising the key findings from the
published evidence, to provide commissioners with a clear
understanding of the effectiveness of physical therapy and
exercise in preventing falls in the elderly population.
How common are fal ls?
Studies estimate that approximately a third of adults aged
65+ in the community will experience at least one fall over a
one year period (Tinetti, 1988), equating to over 3 million falls
per year. The risk of falls and their associated complications
rise steadily with age and frailty level. Of those who are 75+
years, approximately 32%-42% fall each year. Additionally,
previous fallers are more likely to have another fall; studies
estimate between 50% - 67% risk of experiencing a fall in the
subsequent year (Tinetti, 1989; Nevitt, 1989).

WSYBCSU Evidence briefing 2014
Many population based studies have described the rate of
falls in various settings, most notably the community and in
long-term care settings such as nursing homes. In the 65+
age group, conservative estimates of the rate of falls range
from 0.3 – 1.6 per person annually. The figure is estimated to
be double for those in the 75+ age group. Similarly, older
adults living in nursing and care homes have much higher
rates of falls, ranging from 0.6 – 3.6 falls annually (Rubinstein,
2006). Overall, NICE (2013) suggests that in the UK, the rate
of falls is 0.46 falls per patient annually.
The burden on the NHS
Falls and fractures have a major impact on the NHS, costing
more than £2.3 billion per year (College of
Optometrists/British Geriatrics Society, 2011). The number of
people aged 65+ is projected to rise by nearly 50% (48.7%)
from 10.8 million to over 16 million in the next 20 years; a
crude estimate of the cost (excluding inflation) is assessed
to be in the region of £3.4 billion. Therefore, the cost
implications for the NHS are likely to be significantly greater
in the future.
Hip fractures are the most expensive osteoporosis fracture
with the cost per patient estimated to be £25,000. Although
only 5% of falls result in fracture (Tinetti 1988), the impact on
the NHS is significant, with the total annual cost of these
fractures calculated as £1.7 billion (Torgerson 2001). This
figure increases to over £2 billion when the social care costs
are also included (The National Hip Fracture Database
National Report, 2011).
Falls and fractures cost the NHS more than £2.3 billion every year The projected rise in the aging population could increase this cost to over £3.4 billion Although only 5% of falls result in factures, they cost the NHS £1.7 billion annually Falls account for over half of hospital admissions for accidental injury
WSYBCSU Evidence briefing 2014
Falls also has a significant impact on emergency care; falls
account for 10 – 25% of all ambulance call-outs (Dept of
health 2009, Snooks et al, 2006) at an average cost of £115
per call out (Newton et al, 2006). In addition, falls account
for over half of hospital admissions for accidental injury.
Besides the economic cost, there is also the significant
human cost to the patient resulting in the loss of
confidence, loss of independence, diminished quality of life
and mortality. Falling also affects the family members and
carers of people who fall (NICE, 2013).
Can exercise prevent fal ls?
There is now clear evidence falls in the elderly population
can be prevented using carefully designed and tailored
physiotherapy programmes, delivered as either group
exercise or individualised therapy in the home.
Falls intervention programmes can vary greatly from one
programme to another; some programmes deliver only one
type of exercise with the aim of addressing one issue (such
as balance), whereas others may include a variety of
exercises with the aim of addressing multiple attributes (such
as balance, gait speed and strength). Both types of
physiotherapy interventions have been shown to be
effective.
Falls result in loss of confidence, independence, quality of life and mortality Falls also affects family members and carers
WSYBCSU Evidence briefing 2014
Community - Group exercises
The much revered and highly independent Cochrane
group recently published an updated review of the
evidence in falls prevention (Gillespie, 2013). The authors
considered 16 randomised controlled trials (RCTs)
comparing physiotherapy programmes delivering exercise
and standard care (in many cases, this was no intervention).
A total of 3072 patients were included in the analysis. Of the
16 RCTs comparing exercise against the control, all but one
trial favoured exercise in reducing falls with half also
demonstrating statistical significance. A meta-analysis of
the combined data demonstrated the effectiveness of
physiotherapy: the rate of falls was shown to be reduced
by 29% and the risk of falls reduced by 15%. Group exercise
was observed to be effective in both populations that were
at a higher risk of falls as well as populations that were not
identified as high risk.
Exercise interventions should be supervised and supported
by physiotherapists in order to monitor progress. NICE (2013)
guidelines stress that where group exercises are used, they
must be targeted and tailored to an elderly population to
be effective.
Community - Individual exercise regimes
Group exercise programmes may not always suitable for all
patients depending on their overall health and
comorbidities. For these patients, a one-to-one approach
may be more appropriate where highly bespoke exercise
programmes can be tailored by a physiotherapist.
Physiotherapy programmes can reduce the rate of falls by a third Group exercises must be targeted and tailored to an elderly population
WSYBCSU Evidence briefing 2014
The Cochrane review (Gillespie, 2013) examined 7 RCTs
consisting of 951 patients assessing the effectiveness of
individual exercise programmes. Home-based exercise was
shown to reduce the rate of falls by 32% and the risk of
falling by 22%.
Overall effectiveness in the community
In a separate systematic review, Sherrington et al (2011)
reviewed 54 randomised controlled trials considering the
effectiveness of well-designed exercise interventions. Unlike
the Cochrane review, the authors did not distinguish
between the mode of delivery (group or home-based). The
authors estimated a more conservative but nonetheless
statistically significant reduction (16%) in the rate of falls
when compared to control (no intervention or standard
care). The authors concluded that this provided
confirmation that exercise as a single intervention can
prevent falls.
Hospitals and Nursing homes
Unfortunately, the effect of single exercise programmes on
reducing the rate or the risk of falls in adults aged 65+ seems
to be unclear in hospitals and nursing homes. Both
Cochrane (Cameron et al, 2010) and Sherrington et al
(2013) concluded that the reduction in falls in
institutionalised individuals was inconclusive. However, the
Cochrane review found that when the intervention
programme was delivered as part of multidisciplinary co-
ordinated team of healthcare workers, the impact was
significant; the rate of falls was reduced by 31% and the risk

of fa l l s by 27%. The use of mul t i factor ia l
in te rvent ions has a l so been advocated by NI CE
(2103) gu idel ines .
The ef fect on fal ls re lated injur ies
Whilst it is clear that tailored exercise programmes are
effective in reducing the rate and risk of falls in the
community, until recently, it was unclear whether these
programmes can also prevent injuries caused by falls. El-
Khoury el al (2013) conducted a systematic review of 17
RCTs (4305 patients), showing overwhelmingly that fall
prevention programmes not only reduce the rates of falls
but also prevent injuries resulting from falls in older adults in
the community setting. For all injurious falls, the reduction
was estimated at 37%.
The protective effect appeared to be the greatest for the
most severe fall related injuries, with an estimated reduction
of 43% for serious injuries and 61% for falls resulting in
fractures.
How much exercise is required?
Sherrington et al (2011) considered the effect of the amount
of exercise delivered in reducing the rate of falls in the older
adult population. The authors found that the effect was
considerably more pronounced on falls from programmes
that delivered 50+ hours (23% reduction in the rate of falls)
compared to those that had less than 50 hours (7%
reduction). This is also supported by the recent Cochran
review (Gillespie, 2013) where successful exercise
programmes delivered an average (median) of
approximately 50 hours of exercise. Sherrington et al (2011)
therefore recommend that exercise programmes should be
delivered for 6 months with a duration of 2 hours per week.
Falls prevention exercise programmes can reduce injuries by 37% Serious injuries can be reduced by 43% and fractures by 61%
WSYBCSU Evidence briefing 2014
The current dose of physiotherapy where available is
inadequate to be effective; The Royal College of Physicians
(2011) survey highlighted that most (79%) exercise
programmes are delivered for a duration of 12 weeks or less
at a rate of one session per week (74%). This is vastly less
than the recommended 50+ hours.
Access to physiotherapy
Whilst it is known that approximately a third of adults aged
65+ will have at least one fall annually, it is less clear what
proportion of this age group have access to physiotherapy.
In nursing homes, where the risk of falls has been shown to
be higher than in the community (Rubinstein, 2006), a survey
indicated that only 10% of residents were in receipt of
physiotherapy, mostly through private physiotherapists
employed by the nursing home (Barodawala el al, 2001).
Therefore it is likely that the provision of physiotherapy
available through the NHS in the wider community setting
may be less than 10%.
Cost ef fect ives of physiotherapy
Currently, economic evaluations of falls prevention
programmes are very limited. This is further complicated by
the fact that where economic evidence does exist, they are
derived from international studies where the underlying
healthcare system may differ from the NHS. Nonetheless,
simple estimates can be extrapolated from the reduction in
falls related fractures. The cost of falls related fractures
alone has been estimated at £1.7 billion. A 61% reduction in
fall related fractures (as estimated by El-Khoury el al, 2013)
would reduce this cost by £1 billion, though the net saving
50+ hours of physiotherapy is required to be effective Currently, most exercise programmes are inadequate – majority at for 12 weeks or less Only 10% of residents in nursing homes have access to physiotherapy.
WSYBCSU Evidence briefing 2014
would also need to account for the cost of delivering
physiotherapy.
Using data from a retrospective study, Robertson and
Campbell (2008) demonstrated that the Otago falls
prevention exercise programme was cost-effective. The
cost to deliver the programme to a 1000 participants aged
80+ was calculated as $213,000 (NZ dollars), which was
anticipated to have prevented 541 falls resulting in a net
saving of $148,303 (NZ dollars) per 1000 participants. When
translated into British Pounds (May 2014 conversion rates),
this would convert to a saving of approximately £76,000 per
1000 patients or a total of £220 million pounds saving when
extrapolated to the population of aged 80+ adults in the UK;
for every £1 spend, a potential saving of £0.70 may be
realised. It must be noted that these estimates have the
caveat that the healthcare system in New Zealand may not
operate the same tariffs as the NHS and the currency
conversions may also fluctuate. Nonetheless, with limited
health economic evaluations to provide an accurate
costing, these studies provide a good barometer for
potential savings achievable under a well-designed and
tailored exercise programme.
Economic evaluations for falls prevention programmes are very limited. International studies have shown falls prevention exercise programmes to be cost effective saving approximately £76,000 per 1000 patients (aged 80+)

Physiotherapy and Parkinson ’s disease
Int roduction
Parkinson's disease is a chronic, progressive neurological
disease for which there is no treatment or therapy to slow or
stop the progression of the disease. The prevalence of
Parkinson’s disease in the UK has been estimated to be 1 in
500, amounting to approximately 127,000 people living with
the disease in the UK. The prevalence increases to 1 in 100
over the age of 65 years and 1 in 50 over the age of 80
years (Macdonald et al, 2000).
Medications and devices address only the symptoms.
Parkinson’s is the second most common neurological
condition after Alzheimer’s disease, costing the NHS an
estimated £2 billion annually (Fineberg et al, 2013).
Despite advances in medical research, the natural course
of the disease, gait and balance worsen over time,
progressively leading to major disability (Franz´en et al,
2009).

WSYBCSU Evidence briefing 2014
Fal ls in Parkinson’s d isease
The estimated prevalence of falls in those with Parkinson’s
disease ranges from 40% to 90%, with about half of those
falls occurring when walking. The most common reason for
hospital admissions is falls. (Kelly et al., 2012).
Parkinson’s disease patients are more likely to have
impaired stride-to-stride control, leading to an increased risk
of recurrent falls. Studies showed that Parkinson’s disease
patients have a greater than two-fold increased increase
risk of fractures and more than 3 times greater risk of hip
fractures compared to non-Parkinson disease patients after
adjusting for age and gender (Schaafsma et al, 2003).
How effect ive is physiotherapy in
Parkinson’s disease?
A recent Cochran review (2013) of 39 randomised
controlled trials, involving 1827 patients showed that
Physiotherapy was effective in improving the majority of
walking outcomes, with significant improvements
demonstrated in walking speed, walking endurance and
freezing of gait. Improvements were also observed in
mobility and balance with physiotherapy as well as
improvements in the severity of Parkinson’s disease (using
UPDRS scale).
The Cochrane review noted that the majority of the studies
assessed the effects of physiotherapy over the short-term
(less than 3 months). However, the long-term benefits of
127,000 people in the UK live with Parkinson disease Parkinson’s is the second most common neurological disease after Alzheimer’s Annual cost to the NHS of £2 billion pounds
WSYBCSU Evidence briefing 2014
Physiotherapy in Parkinson’s disease has been confirmed in
recent studies. The Michael J Fox foundation conducted an
RCT of 210 patients with Parkinson’s disease over 12 months,
comparing two different Physiotherapy programmes
(Movement strategy training [MST] and progressive
resistance strength training [PST]) with usual care (control
group receiving a PD education program without falls
education). The study showed that there was a significant
reduction in the rate of falls and the severity of Parkinson’s
disease in both physiotherapy treatment groups over 12
months. The rate of falls was reduced from 18.6 falls per
patient in the control group to 6.58 in the MST and 2.79 in
the PST physiotherapy groups (Morris et al, 2014).
The long-term benefits of physiotherapy were also assessed
by Frazzitta et al (2013). In a preliminary study of 20 patients
who underwent a 4-week intensive physiotherapy
programme, balance and gait speed was demonstrated to
have improved significantly after the treatment
programme. At 1-year follow-up control, walk and
Comfortable-Fast gait speeds remained significantly better
than baseline measures.
Studies have demonstrated the short and long-term effectiveness of physiotherapy in Parkinson’s disease The rate of falls was significantly reduced from 18.6 per patient in the control group vs 6.58 and 2.79 in two physiotherapy groups.

Physiotherapy and Frailty
Int roduction
Frailty is a state of vulnerability that carries an increased risk
of poor outcomes in older adults. Though common in the
elderly, frailty is not an inevitable consequence of the
ageing process. Frailty is a term that described a subset of
adults that greater risk of adverse health outcomes, such as
falls, less mobility, less independence, hospitalisation,
disability, and death. Unfortunately, there remains no
common consensus on the definition of frailty. It is widely
accepted as a multifactorial, clinical syndrome, consisting
of a combination of weight loss, fatigue, impaired grip
strength, diminished physical activity or a slow gait (Fried et
al, 2001).
Definitions of frailty fall into two groups: One group of
researchers define frailty as a purely physical condition,
whilst a second group of researches define frailty according
to a broader definition to include social and psychological
components of the condition (Collard, 2012).
There is no consensus on the definition of frailty Characteristics of frailty include weight loss, fatigue, impaired grip strength, diminished physical activity or a slow gait
WSYBCSU Evidence briefing 2014
Prevalence of f rai l ty Frailty is increases in prevalence with age and is generally
believed to be higher in women than in men. However, there
are wide discrepancies in the estimated prevalence rates of
frailty, to which the lack of common definition will have certainly
contributed to the variability is estimations. A systematic review
of 21 studies, estimated the prevalence of frailty in a community
dwelling to be in the range of 4.0% to 59.1%. In studies where
frailty was defined as a physical condition, the estimates of
frailty ranged between 4% - 17%. When a broader definition of
frailty was employed, there was a greater variability in the
estimate of prevalence (between 4.2% - 59.1%) (Collard et al,
2012).
Where frailty was specified by gender, a higher rate of frailty
was observed in women (9.6%) compared to men (5.2%). Frailty
was also observed to increase with age, ranging from
approximately 4% for adults aged 65-69, rising to 27% in the 85+
age group (Collard et al, 2012).
Ef fects of physical activ i ty on f rai l ty.
Two systematic reviews have examined the effect of physical
therapy on frailty (Arantes et al 2009, Clegg et al 2012). The
diversity of criteria used to define frailty makes it difficult to
compare and synthesise outcomes from studies to draw firm
conclusions. Both studies agreed that there was preliminary
evidence from one trial to suggest that physical therapy may
have a positive effect on reducing disability compared to
patients receiving solely an educational programme, with the
effects maintained for 12 months. The effects were most
pronounced in older adults with moderate frailty rather than.
Estimates of frailty vary considerably, between 4% - 59% depending on the definition used.
Frailty increases with age. Women have a greater prevalence than men
WSYBCSU Evidence briefing 2014
severe frailty, where no improvements were observed.
Both systematic reviews emphasised the limitations of the
studies and could not provide any certainty on the effects of
physical therapy on outcomes such as quality of life, long-term
care admissions and the progression of frailty until further
adequately designed RCTs are conducted. Greater consensus
is also required in the definition of frailty to help synthesise
studies.
Preliminary studies suggest physical therapy may reduce disability in frail adults. More studies are required provide greater clarity on the effectiveness of physical therapy in frailty.
