Patent attributes
An intraoperative neural monitoring system for use during a surgical procedure on a subject includes a mechanical sensor and a processor. The mechanical sensor is configured to monitor a physical motion of a muscle of the subject and provide a mechanomyography (MMG) signal corresponding to the monitored physical motion. The processor is configured to receive the MMG signal, apply a wavelet transform to the MMG signal, and determine, from the output of the wavelet transform, if the monitored physical motion of the muscle is an artificially induced neuromuscular response that is attributable to an applied electrical stimulus. If the processor determines that the monitored physical motion of the muscle is an artificially induced neuromuscular response, it then provides an indication to a user.
