1. A neural monitoring system comprising:

  • an elongate medical instrument having a distal end portion configured to extend within an intracorporeal treatment area of a subject, the elongate medical instrument including a plurality of electrodes disposed on the distal end portion, each electrode respectively being configured to provide an electrical stimulus;

    a non-invasive mechanical sensor configured to be placed in mechanical communication with a muscle of the subject and to generate a mechanomyography output signal corresponding to a sensed mechanical movement of the muscle; and

    a processor in communication with the elongate medical instrument and the mechanical sensor, and configured to;

    receive the mechanomyography output signal; and

    determine a relative direction between a nerve and the distal end portion of the elongate medical instrument via the received mechanomyography output signal, wherein the nerve innervates the muscle.
