Family Support: The Role of the Pediatric Audiologist Karen M. Ditty, M.S. Texas ENT Specialists, P.A. Antonia Brancia Maxon, Ph.D. Diane Brackett, Ph.D. New England Center for Hearing Rehabilitation 354 Hartford Tpke. Hampton, CT 06247 860-455-1404 nechear@snet.net NECHEAR
Parental Reaction (Luterman) • Mourning “the lost normal child” • Shock • Recognition • Denial • Acknowledgment • Constructive action • Parental Expectations NECHEAR
Parental Reaction (Luterman) • Audiologist’s role • Understand where parents are in process • Consider amount of information they can handle at any given time • Repeat information • Consider culture • Culture, community, access NECHEAR
Parental Reaction (Luterman & Maxon) • Parents are overwhelmed • Long term vs. short term goals • “Fixing” the problems • Where does child “belong?” • “Taking care of” the child • How the family changes NECHEAR
What is the pediatric audiologist’s role in diagnosis and intervention ? Explaining hearing, hearing loss and amplification NECHEAR
Auditory Development Skill Age Behavior Localization 6 mos Head turn to source Min Aud Angle 6-18 mos Decreases 15-40 Detect duration differences <6 mos <= 20 msec Pitch perception <6 mos large for detection Speech perception 1 month VOT can be made 2 mos Falling vs. rising F0 9-18 mos Prefer highly novel NECHEAR
Speech Signal Discrimination • Learning about inflection • angry vs. soothing • question vs. statement • Learning about intensity • loud vs. soft • near vs. far • Perceptual categories • consonants • vowels NECHEAR
Auditory Connections • Objects make specific sounds • Important people make specific sounds • Food preparation has specific sounds • Toys, pets, etc. make specific sounds • Auditory feedback loop critical NECHEAR
What is the pediatric audiologist’s role in early intervention? Understanding and explaining typical spoken language development NECHEAR
What is progress? Define the area of communication you are talking about…. - auditory skills - speech - spoken language NECHEAR
How does language develop in normally hearing children? • Listening, speech, and language develop simultaneously. • Meaning is established by hearing sounds, words, phrases used in a particular situational context. • Refinement of skills occur by comparing one’s own production with a model. • Spoken language development continues into adolescence. NECHEAR
How does spoken language develop in children with hearing loss? The same way if the child has access to spoken language through appropriate sensory device. • Listening, speech, and language simultaneously. • Meaning = hearing in context • Refinement occurs with comparison to a model. • Spoken language development through teens. NECHEAR
BUT…….. • It is difficult to provide sufficient audible exposure to language in totally natural situations • The parent/therapist needs to purposely increase exposure to spoken language to counteract the many times that it is “masked” by noise or distance. • The “conscious” process of ensuring reception and understanding begins at identification and continues through adolescence. NECHEAR
EXPECTATION • Children who grow up using appropriate sensory devices have the potential to develop superior spoken language skills. • Achievement of that potential is dependent on: • quality of the auditory information • dependence on auditory information • input from parents/therapists/children • high expectations NECHEAR
What is the pediatric audiologist’s role in early intervention? Basic principles of early intervention NECHEAR
Service Provision • Families should have equal access to a coordinated program of comprehensive services that: • foster collaborative partnerships • are family centered • occur in natural settings • recognize best practice in early intervention • are built on mutual respect and choice NECHEAR
Audiologic Habilitation • Pediatric audiologist • expertise in infant hearing aid selection and fitting • expertise in using appropriate pediatric testing equipment and methods • experience working with infants and their families • flexibility in scheduling NECHEAR
Audiologic Habilitation • Pediatric aural rehabilitationist • expertise in • infant development • infant auditory development • infant speech and language acquisition • experience working with infants and their families • flexibility in scheduling NECHEAR
What is the pediatric audiologist’s role in early intervention? Supporting family’s understanding of language choices NECHEAR
Communication Modality • Spoken language options • auditory-verbal • use amplified residual hearing to learn to listen, comprehend spoken language • uses auditory input only • oral/aural • use amplified residual hearing to acquire spoken receptive and expressive language • uses auditory input with speech reading when necessary NECHEAR
Communication Modality • Spoken language options • cued speech • use hand configurations and positions to assist in identifying and discriminating among visible speech sounds • uses auditory input when possible • total communication • use all means of communication (sign, auditory) to acquire spoken language - e.g., Signing Exact English NECHEAR
Communication Modality • American Sign Language • A separate language - not based on spoken English • Use hand signs and finger spelling to acquire language with its own vocabulary and syntax • Does not use auditory input NECHEAR
What is the pediatric audiologist’s role in early intervention? Helping families understand and select sensory devices NECHEAR
Purpose of Amplification • Accessing the Speech Signal • Speech must be well above detection within an appropriate dynamic range • Maximal exposure to speech spectrum • Maximizing use of residual hearing • Develop/maintain auditory feedback loop NECHEAR
Amplification Candidacy • Any child with any degree of hearing loss is a candidate for amplification • Without amplification • with 15 dB HL thresholds 98% of everyday speech is received • with 40 dB HL thresholds 50% of everyday speech is received • with 55 dB HL thresholds 5% of everyday speech is received NECHEAR
Initiate amplification process immediately after diagnosis or change in hearing levels Select, fit and validate amplification with clinical and functional evaluations Pediatric Amplification Fitting NECHEAR
Pediatric Hearing Aid Fitting/Validation • Ongoing process with flexible instrument • Clinical measures • More audiological data - setting adjustment • Observe behaviors, communication, environment • Audiologist • Family • Service providers NECHEAR
Pediatric amplification fitting • Audiologist should use real-ear measures • Audiologist should use prescriptive fitting • Audiologist should have experience with functional measures of benefit • Audiologist should have scheduling flexibility and understand the need for immediacy of fitting NECHEAR
What is the pediatric audiologist’s role in early intervention? Helping families understand problems and daily use of amplification NECHEAR
Practical Problems Problem Solution Maintaining BTE Huggies, Strap holder, clips Removing batteries Battery door lock Changing volume Volume cover, deactivate volume NECHEAR

What is the pediatric audiologist’s role in early intervention? Helping families understand candidacy for cochlear implants NECHEAR
UNHS affects the age of cochlear implant candidacy identification • Bilateral severe to profound sensorineural hearing loss • Infant/toddler cannot benefit from traditional amplification • 12 months old is recommended lowest age. • Some surgeons are implanting younger infants. NECHEAR
Factors that Facilitate CI Success • Parents know about hearing loss and accept long-term problems • Parents understand the implant is not a cure • Parents are committed to implant use • Parents are committed to therapy NECHEAR
Factors that Facilitate CI Success • Family has access to therapy and mapping facilities • Family is motivated • One parent at home - minimal day care • The household is organized • Child is vocalizing NECHEAR
What is the pediatric audiologist’s role in early intervention? Helping families understand problems and daily living with a cochlear implant NECHEAR
Information Needed by Parents • Parents wanted most information prior to surgery, but wanted continued informational support post-implant • Parents felt emotional support was most lacking • Majority of parents felt there needed to be a professional liaison between CI center and educational program (Most and Zaidman-Zait, 2003) NECHEAR
Information and Follow-up for Parents • Cochlear implant orientation and ongoing support for all care providers • On-going mapping after initial stimulation • When changes in responses to sound are seen • When changes in vocal/verbal output are seen • On-going service by early intervention provider NECHEAR
