A method of alerting a user to the existence of an artificially induced neuromuscular response in a subject includes: generating a series of electrical stimuli at a predetermined period with an electrode disposed at a distal end portion of an elongate medical device; detecting a series of mechanomyographic (MMG) responses of the subject using a mechanical sensor, each MMG response indicative of a contraction of a muscle of the subject; determining a degree of statistical confidence that the detected series of MMG responses was artificially induced by the series of electrical stimuli; and outputting, to the user, both an alert that a series of MMG responses has been detected, and the determined degree of statistical confidence that the detected series of MMG responses was artificially induced by the series of electrical stimuli.
