Abstract
A method of detecting an induced muscle response includes monitoring a mechanical parameter of a muscle; computing an amount of muscle jerk from the monitored parameter; comparing the computed muscle jerk to a jerk threshold; and identifying the occurrence of an induced muscle response if the computed muscle jerk exceeds the threshold.
Claims21
A method of detecting an induced muscle response comprising:
- monitoring a mechanomyographic (MMG) response of a muscle using a mechanical sensor in mechanical communication with the muscle, the MMG response being attributable to a depolarization of a nerve innervating the muscle, the depolarization being in response to a provided electrical stimulus;
- computing a time derivative of acceleration from the monitored MMG response;
- comparing the computed time derivative of acceleration to a threshold;
- and
- identifying the occurrence of an induced muscle response if the computed time derivative of acceleration exceeds the threshold.
