Stapedial reflex in amyotrophic lateral sclerosis.
OBJECTIVE To examine mechanisms controlling the stapedial reflex in patients with amyotrophic sclerosis (ALS). METHODS The stapedial reflex was examined using impedance audiometry in 38 patients with sporadic ALS and in 25 age matched controls. RESULTS All patients showed normal reflex decay test results. There were no significant differences between patients with ALS and control subjects i...
متن کاملThe importance of electrically evoked stapedial reflex in cochlear implant.
INTRODUCTION The most important stage in fitting a cochlear implant is the identification of its dynamic range. The use of objective measures, in particular the electrically elicited stapedius reflex, may provide suitable assistence for initial fitting of cochlear implant, especially in children or adult with multiple disorders, because they provide specific values that serve as the basis of ea...
متن کاملStapedial reflex and ears with high static acoustic admittance.
PURPOSE To evaluate modified acoustic reflex diagnostic protocols for a group of individuals (n = 9) with high peak compensated static acoustic admittance (Y(tm)) tympanograms. METHOD A modified procedure designed to improve acoustic stapedius reflex threshold (ASRT) measurements in individuals with high-admittance tympanograms was employed in both an experimental and a control group. ASRTs w...
متن کاملReflex Modification Audiometry Reveals Dual Roles for Olivocochlear Neurotransmission
Approximately 15% of American adults report some degree of difficulty hearing in a noisy environment or have auditory filtering difficulties. There are objective clinical tests of auditory filtering, yet few tests exist for mouse models that do not rely on extensive training. We have used reflex modification audiometry (RMA) and developed exclusion criteria for the mouse model. This RMA based t...
متن کاملMeasurement of comfort levels by means of electrical stapedial reflex in children.
BACKGROUND Patient success and satisfaction with a cochlear implant largely depend on the adequacy of the speech-processing program. The program is generated by means of behaviorally determined threshold and comfort levels for each electrode. As the minimum age for implantation continues to decrease, behavioral methods of measuring comfort levels have become more problematic, and so the need fo...
