摘要： A method and system for detecting the proximity of a nerve to a proximity electrode and status of nerve. The method of detecting the status of the nerve (30) includes the steps of placing an electrode near the nerve (32); providing an electrical signal having varying current levels to the electrode (34) to stimulate the nerve; measuring an EMG response of the nerve for the applied current (36); mapping the EMG responses (38) of the nerve for the applied electrical signal for a fixed latency; and determining the status of the nerve based on the mapping of the responses (42).
