1. Explain what symptoms or patient characteristics for which it would be appropriate to test balance disordered patients with computerized dynamic posturography. 2. Patients with compensated unilateral vestibular lesions will show 01 (increased or decreased) gain and 02 (increased or decreased) phase lead at low frequencies of stimulation on rotary chair testing. 3. Patients with uncompensated unilateral peripheral vestibular lesions will more than likely show (symmetry or asymmetry) 01 in their response during rotatioal testing. 4. Which of the following are true about rotational testing? (You may select more than one answer.) a. Rotary chair testing is performed with the assumption that the stimulus that is applied to the whole body is the same as that applied to the head. b. Patients' whole body is rotated in passive rotational tests. c. The patient’s eyes move in a direction opposite to the rotation of the chair d.

Unformatted text preview: body remains stationary. 5. On testing with the Halmaygi Head Thrust test, a patient shows corrective saccades and reduced VOR gain when the head is rotated toward the right side. These results are consistent with VOR dysfunction on the 01 side. 6. Which of the following cases would be appropriate to test with rotary chair? (You may select more than one answer.) 1. Pediatric patients not testable with ENG or VNG. 2. Geriatric patients. 3. Patient with bilateral caloric weakness. 4. Patient with BPPV. 7. To test postural stability, patients step in place for 50 steps with eyes open and then 50 more steps with eyes closed during the 01 test. 8. Briefly explain the purpose for rotary chair testing. 9. Explain why rotational testing is an important supplement to the traditional VNG/ENG battery. 10. Describe the Romberg Test and its clinical utility in the assessment of dizzy patients....
