Syllabus for Clinical Audiology II CD 5706

Syllabus for Clinical Audiology II — CD 5706 ABR (mostly) and ENG

Instructor: Robert de Jonge, PhD, Martin 58, 660-543-8809, [email protected] Text: •Handbook of Auditory Evoked Responses (1992), James W. Hall III

Supplemental Texts: •Handbook of Balance Function Testing (1997), Gary P. Jacobson, Craig W. Newman, Jack M. Kartush •Contemporary Perspectives in Hearing Assessment (1999) edited by FE Musiek and WF Rintelmann, Allyn and Bacon.

Exams/Assignments: There will be practicals plus two exams, each exam will be fill in the blank, short answer essay. The final is not comprehensive. Also, keep a journal of your practical experiences in performing the ENG battery and evoked potentials. The purpose of the journal is to demonstrate what you have learned, to document the testing you have accomplished, and to demonstrate that you can administer the procedures and interpret the results. Completed journals will be due at final exam time. See "Practicals…" in the class notes for more information.

Class Attendance: Attendance policy is consistent with University policy. In addition, four absences are allowed for whatever reason (approved or not, at your discretion). Beyond this the final grade is reduced by 1/4 of a letter grade for each additional absence. The final grade will be increased by 1/4 for each of the allowed absences that is not used. Perfect attendance improves performance by one full letter grade.

Class goals: The general purpose of the class is to provide:

1. An overview of the anatomy and physiology of the balance system; 2. An introduction to the evaluation of the balance system through electronystagmography (ocular motility, positional and positioning, and caloric testing); 3. An introduction to the electrophysiological evaluation of the auditory system: primarily the auditory brainstem response (ABR), but also including electrocochleography (EcochG), auditory middle latency response (MLR), the auditory late response (ALR), P300 response and mismatch (or mismatched) negativity (MMN); 4. An understanding of the ENG and evoked potential test protocols, and an ability to perform and interpret the tests.

Topics ENG •Anatomy and physiology of the vestibular system and ocular motor system. Read Jacobson et al., chapters 2 and 3. •Ocular motility testing. Read Jacobson et al., chapters 5 and 6. •Positional and positioning testing. Read Jacobson et al., chapter 7. •Caloric testing. Read Jacobson et al., chapters 8 and 9.

Evoked Potentials •An overview of EcochG, ABR, MLR, ALR, P300, and MMN. Read Hall's chapter 1, and the portion of chapter 8 in Musiek and Rintelmann dealing with MMN. •Test protocols and procedures: practical suggestions for patient preparation, equipment setup, testing, and cleanup. Read Hall's chapter 8. •Waveform analysis: peak picking. Read the "Introduction" and the section on "Conventional Waveform Analysis," Hall's chapter 6, pages 221-242. •Peripheral auditory assessment: the effect of degree and configuration of hearing loss on AERs. Read Hall's chapter 11. •Neurodiagnosis of eighth nerve, cerebellopontine angle, and extraaxial pathology. Read Hall's chapter 12.
