Stenger Testing

• Symptoms

• 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
