Audiologic Rehabilitation for Children
• Differ according to type of hearing loss and when the loss was identified.
• Differs according to age groups (preschool, school-age)
Rehabilitation Settings and Providers
WHAT IS A COCHLEAR IMPLANT?
• Electronic prosthetic device• Surgically implanted in the scali
tympani of the cochlea• Bypasses damaged hair cells in the
cochlea• Electronically stimulates auditory
neural elements that do not respond to acoustic stimulation with hearing aids
BASIC COMPONENTS • External Microphone• Speech Processor• Battery Component• Coil/transmitter• Receiver/Stimulator• Magnet for Retention• Implanted Electrode array
HOW DOES IT WORK?• External microphone converts
incoming sound into electrical signal
• Speech processor converts electrical signal into a digital code (speech processing strategy)
• Signal is transmitted across the skin
HOW DOES IT WORK?• Implanted cochlear stimulator receives the
coded signal and delivers it to the electrode array
• Electrodes stimulate cochlear neurons• Bypasses damaged hair cells• Nerve impulses are sent along the
auditory pathways to the cerebral cortex• Allows the brain to perceive sound
MAPPING• Term utilized for programming external
device• Occurs approximately 4 weeks after surgery• Laptop computer utilized• Objective measures utilized• Progressive maps• Plateau/stabilization• Regular maintenance schedule

PREDICTIVE FACTORS• Medical conditions• Communication strategies• Language development• Mode of education• Family support/dynamics• Developmental delay• Adolescents – poorer prognosis• Variability exists
TEAM APPROACH• Surgeon• Audiologist• Auditory Verbal Therapist• Speech/Language Pathologist• Nurse/O.R. Staff• Educator• Early Interventionist• Coordinator/Case Manager• Administrative
Yes! SLPs Need to Know• Pre-CI
Audiograms are Important
• Always get most the most updated audiogram!!!
Communication, Communication, Communication
• You and the audiologist will work together to get the best program for your client.
• You can help with ease of programming and adjustment to new programs with young children.
• You provide valuable information to the audiologist about your client’s functional use of his/her implant.
Adjusting to the Cochlear Implant
• You are usually on the “front line”.• Advising parents about saturation.• Talk about realistic expectations.• You provide lots of encouragement and
education!!! – Pointing out the gains in auditory skills that
you see.– Letting them know what is typical “tolerance
issues”.
Remember!!!!
Every client is different and comes to you will a diverse
background (language, social environment, hearing,
personality, family).
Keep in mind that a your client’s ability to receive the sounds of speech is only the
first step…….
Why do we address auditory skills in therapy?
• In both children and adults, we use it to fully develop their use of available sounds.
• In children, effective listening becomes their foundation for the development of spoken language.
Auditory Skills? You need to know where your client’s
auditory skills fall in the hierarchy.Each therapy session will be diagnostic in
nature.
Basic Stages of Auditory Development
ComprehensionIdentification
DiscriminationDetection
DetectionThe awareness of whether a sound is
present or not
Detection activities should be…
MotivatingSimple and quickAge appropriateVaried
• Also work on generalizing auditory attention.• Must be established as a foundation for
learning to listen• Timers• Name calling• Eventually the child will alert to
environmental sounds and speech without cues
Auditory Attention
• Should be…– Motivating– Simple and quick– Age appropriate– VariedActivity SuggestionsBalls, puzzles, mechanical banks, stacking toys,
peg boards, black towers, beanbag or ball toss, stringing beads, letters in a mailbox…..
Detection: Conditioned Response Activities
Discrimination• Distinguishing differences
between sounds• The listener's ability to tell
whether two sounds are the same or different.
Keep in mind the Acoustic Contrasts within the Discrimination Task
From Easiest to Most DifficultSuprasegmentals Syllable LengthVowel Differences (bat, bet, boot) Manner of Production Differences
(t vs. sh)Voicing Differences ( p vs. b)Place of Production Differences (k
vs. t)
IdentificationA person's ability to
recognize a sound and then label it
Comprehension• A person’s ability to understand
the meaning of the spoken message
• This level requires that the person have a certain degree of semantic and syntactic language development
• Also work on generalizing auditory attention.• Must be established as a foundation for
learning to listen• Timers• Name calling• Eventually the child will alert to
environmental sounds and speech without cues
Auditory Attention
Always keep in mind the variables that affect how challenging a therapy task is for your client.
What is your Listening Set?
ClosedBridgeOpen
What are the contents of your set?
Keep in mind….• The familiarity of the vocabulary• How the items acoustically contrast each other• The number of key words being used and where
they are place• The linguistic complexity of what you are
presenting
How are you presenting the stimulus items?
• What is your rate of speech? • Are you using acoustic highlighting?• Is there background noise?

Why do I need to use them?When do I use them?

Also….absence of sound
• These are used to teach the skill of listening to the younger child
• They differ greatly in terms of duration, intensity and pitch.
Sound-Word Associations
• Many of these associations are commonly used in traditional, early language therapy
• Once the child learns the associated sound then the true word is given
Sound-Word Associations
• Auditory Information• Visual Clarifier• Auditory Information
Transitioning Between Visual and Auditory
• These are used to teach the skill of listening to the younger child
• They differ greatly in terms of duration, intensity and pitch
• Many of these associations are commonly used in traditional, early language therapy
• Once the child learns the associated sound then the true word is given
Sound-Word Associations
Some Examples of Sound-Word Associations
Up, up, up, weeee Mooooo
Ahhhhhhhhh(rising and falling intonation)
Listening for Littles,1997
• Imitation is not identification• Closed versus open set
– Complex closed sets may be easier than single word in a open set
– A “bridge set” may be used to connect between closed versus open sets
– Content and presentation determine the level of challenge
Keep in mind…….
• Acoustically highlight the key word
• Model a similar question with another person
• Use familiar information and vocabulary to introduce word
• Use descriptions
When they don’t get it the first time….
• Instructions on assembly provided
• Materials needed– Embroidery hoop– Stereo speaker cloth
