Objective electrophysiological measures from cochlear implant patients.
Various objective electrophysiological techniques have been used to supplement the behavioral measurements for cochlear implant patients. This report summarizes various studies of these measurements, including stimulus artifact, averaged electrode voltages, electrical stapedius reflexes, electrical auditory brain stem responses, electrical middle latency responses, and cortical auditory responses. These techniques have been shown to provide valuable information in the evaluation of device and electrode integrity in addition to correlated values to behavioral thresholds and comfort levels.
