1. A system for detecting the presence of a nerve within a subject comprising:
- a stimulator configured to provide a stimulus to a portion of the subject;
a sensing device configured to be placed in communication with a muscle of the subject and to generate an output signal corresponding to a monitored parameter of the muscle, wherein the sensing device includes a mechanical sensor; and
wherein the monitored parameter includes a mechanical parameter of the muscle, anda processor configured to;
receive the output signal from the sensing device;
determine if a portion of the output signal was induced by the stimulus provided by the stimulator;
provide a first indicator if the portion of the output signal was induced by the stimulus; and
provide a second indicator if the portion of the output signal was not induced by the stimulus.
