CONTRACTION
The electrode impedance mirrors the electrical resistance and gives additional information about a successful electrode array insertion and the technical integrity of the device. Electrical Stapedius Reflex Thresholds (eSRTs) are measured by visually observing the contraction of the stapedius muscle in the implant ear. Moreover, the function of CI and nerve was monitored by Electric Compound Action Potentials (ECAPs). Spread of Excitation (SOE) [
