Prediction of dynamic range from stapedius reflex in cochlear implant patients.

Amplitude growth functions of the electrically elicited stapedius reflex were compared with behavioral estimates of dynamic range in seven patients using multielectrode cochlear implants. The range between threshold and saturation level of the amplitude growth function usually either encompassed or fell between the preferred and uncomfortable listening levels. Implications of these findings for the initial mapping of electrodes in young children are discussed.
