Rhythm increases perceptual tolerance when measuring electrically evoked compound action potentials in cochlear implant recipients.

ABSTRACT: In cochlear implant (CI) recipients, measurement of the electrically evoked compound action potential (ECAP) is used in clinical routine to prove the electrode-nerve interface and to support fitting, especially in very young children. To record an ECAP amplitude growth function (AGF), electrical stimuli are presented at increasing intensities up to the maximum acceptable loudness (MAL). However, a continuously monotonically rising sound can quickly be perceived as unpleasant and thus impair the success rate of ECAP threshold determination. The present study investigates whether perceptual and objective parameters, which are involved in ECAP measurements, depend on the type of stimulus presentation. In 27 subjects with a CI (28 implants), stimuli of five different AGF patterns were presente
