Abstract
A method and system for detecting nerve status and relative movement between a nerve and a proximity electrode. The method determines relative movement between a nerve and a proximity electrode by applying multiple signals to a calibration electrode where the energy level of each signal induces a predetermined nerve response. The method also applies multiple signals to the proximity electrode where the energy level of each signal also induces a predetermined nerve response. Based on the variation of the energy level of signals required to induce predetermined nerve responses, the method may detect relative movement between a nerve and a proximity electrode and nerve status.
