Week 9 Slides Review Flashcards
Differences between electrophysiological and behavioral testing procedures.
Behavioral: requires cooperation, direct measure of hearing, easily obtained in infants, parents can easily observe & understand results
Electro: doesn’t require cooperation, easily obtained under 6 mos, requires sedation over 6 mos, not a measure of hearing, cannot be used to monitor HAs or CIs
Predominates in decision making in management of HL (under 6 mos - OAE, ABR, tymps)
electrophysiological
6 mos-5yrs is dev appropriate behavorial assessment, tymps & ARTs
behavioral
When there is hL and tymps are normal, do
oaes
Behavioral responses are not reliable and give no ear specifics and hL is evident, do
abr
newborns
birth to 6 mos
infants
6 mos to 24 mos
young kids
25-60 mos
Recommended test protocols for newborns (0-6 months)
Relies on physiological measure
Case hx, parent report, behavioral observation (BOA), dev screenings (cognitive & motor dev), functional aud assessments (ITMAIS, LITTLEEARS)
Recommended test protocols for infants (6-24 months)
Behavioral assessments
Vra
Sdt for younger
Srt for older if they can
OAEs
Dev & functional aud assessments
ABR only when
Behavioral audiometric tests are unreliable
Ear-specific thresholds cannot be obtained
Behavioral results are inconclusive
Auditory neuropathy is suspected
Recommended test protocols for young children (25-60 months).
Behavioral tests & acoustic immitance
Vra for younger
Cpa for older
Can try conventional for older
Older can do srt & wrs
Younger than 5 close
Older than 5 attempt open
OAEs, dev screen, function aud assessment
Infants between approximately 5- and 24-months developmental age.
for speech
sdt
Children with receptive language skills of two years and older.

Importance of including behavioral tests in evaluations.
provides valuable information not available from electrophysiologic testing.
true measure of threshold sensitivity and is considered the “gold standard” for hearing assessment
Importance of applying the cross-check principle in pediatric assessments and how it is used.
Achieved with test battery approach
Multiple tests cross check each other to ensure accuracy
several appropriate behavioral and electrophysiologic tests must be used to determine the extent of a child’s auditory function.
