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.
ex of cross check principle
OAEs, ABR, case hx (do they turn to sounds, are there concerns), tymps, reflexes, etc.
all help to determine more accurate diagnosis
Advantages of test battery approach:
Provides detailed information
Avoids drawing conclusions from a single test
Allows for the identification of multiple pathologies
Provides a comprehensive foundation for observing a child’s auditory behaviors
wahat affects behavioral assessment
state of child
audiologists skills
assistance
testing environment and setup
past experience
how can hou set up the room
Two room with one audiologist and one parent who also function as a test assistant.
Two rooms with two audiologists, or one audiologist and one test assistant
One room with one audiologist
functional auditory assessment
important for test battery
numerous test & surveys
Can be completed by the teacher, student, or parent before and after the use of a hearing aid, cochlear implant, personal remote microphone (RM), or soundfield system or the delivery of therapy or educational services.
what is an example of an auditory assessment
LittlEARS Auditory Questionnaire
Designed for infants and toddlers, this parent questionnaire evaluates auditory development in children up to 2 years old. It helps assess whether the child is meeting auditory milestones for their age, such as responding to environmental sounds or vocalizing in response to sounds.
what must a report include
Appropriate demographic information, name, medical record number, birth date, date of test, and place of test as required by state legislation.
Adequate detail of test procedures
Original graphics of test results when possible (tympanometry tracing, ABR waveforms).
Audiologic Diagnosis.
Summary and Conclusions.
Follow-up Plan.
Signature, contact information and credentials of the audiologist completing the assessment.
For children under 3 with hearing loss, notify the IDEA Part C provider within 48 hours.
true
Provide families with written, accessible information on test results, implications, and next steps.
true
Importance of evaluating cognitive age and physical status, and how these affect test protocols.
essential in determining the most appropriate test protocols for auditory assessments. These factors help ensure the tests are both accurate and meaningful, as they can significantly impact how a child responds during the evaluation process
Cognitive age influences how long a child can participate in testing, prompting audiologists to use shorter test protocols or multiple sessions if needed.
