The procedure involves applying the device to a suitable anatomic location for train of four (TOF) stimulation/monitoring and then applying a small electrical pulse to stimulate the patient's motor point. The location for this stimulation has historically been on the patients forearm over the ulnar nerve area or on the patients face in the distribution of the facial nerve. The stimulation applied to these areas is equivalent to that applied in the current accepted standard of care. All responses measured by the device will be recorded electronically and compared to anesthesiologist's/nurse anesthetist's interpretation of the number of muscle twitches induced by peripheral motor point stimulation. These comparisons will be analyzed for correlation between number of muscle twitches and degree of force generation sensed by the device, with the aim of more accurately determining the degree of the patients neuromuscular blockade.
