  2. Progress Reports • Volunteers

  3. Vestibular disorders • Symptoms • Lack of balance • Stabilization • Correction • Vertigo • Dizziness • Nausea • Population • Recent acoustic trauma • Barometric trauma • Weightlessness • Diagnosis • Malfunctioning inner ear • Overstimulation • Physical activity • Habituation

  4. Stenger Testing • Symptoms • Tinnitus • Unilateral hearing loss • Sporadic pain • Population • Anyone • Children • Middle-aged industrial workers • Diagnosis • Pseudohypacusic • Normal ABR • Stenger test positive

  5. Stenger Testing II • Auditory phenomena • Simultaneous bilateral tone presentation • 10 dB HL difference between ears • Only louder tone is heard • Stenger administration • Bilateral, simultaneous presentation • 10 dB HL difference between ears • Poorer ear presented at 10 dB HL, 0 dB HL in good ear • Adjust both ears analogous to normal audiometric threshold • Stenger negative • Response to good ear • Stenger positive • No response to threshold

  6. Bilateral Pseudohypacusic • Yes-No test • Procedure • Present tones above/below threshold in each ear • Subject: yes-no to each presentation • Temporal arhythmicity • Are no responses correlated to onset of presentations? • Best with children

  7. Pulse-Count Method • Rapid succession of tones presentations • Arhythmic presentations • Vary ear of presentation • Tones above and below admitted threshold • Subject responds with the total number of tones heard • Does total correlate with actual tones presented above threshold • Modification • Present all tones above threshold

  8. Why choose Psuedohypacusis? • Veteran benefits • Additional health care funding • Disability earnings • Post WWII peak (half of reported cases) • Hearing histories for modern soldiers (1-4%) • Industrial worker compensation • Compensation, disability benefits • Transfer of duties • 15-30% of reported cases • Children • Poor academic performance excuse • Attention-getter • Up to 5% of reported cases
