A neuromuscular sensing method includes transmitting an electrical stimulus from a distal end portion of an elongate stimulator extending within an intracorporeal treatment area of a subject and detecting an artificially induced response of at least two muscles of the subject in response to the transmitted electrical stimulus, each response being detected by a respective sensor in mechanical communication with the muscle. A graphical user interface (GUI) is transitioned from a first state to a second state; the first state indicating to the transmission of a stimulus with no artificially induced response detected, and the second state indicating the detection of the artificially induced response of the at least two muscles, and further identifying one of the at least two muscles as a primary muscle response.

Intraoperative neural monitoring system and method

A sensing device for detecting an artificially induced neuromuscular response within a limb of a subject includes a carrier material and a plurality of mechanical sensors. The carrier material is operative to be secured around a portion of the limb, and each of the plurality of mechanical sensors are coupled with the carrier material. Each mechanical sensor is positioned on the carrier material such that it is operative to monitor a mechanical response of a different muscle group of the limb. Each mechanical sensor then generates a respective mechanomyography output signal corresponding to the monitored mechanical response of its adjacent muscle group.

Neuromuscular sensing device with multi-sensor array

A neural monitoring system for detecting an artificially-induced mechanical muscle response to a stimulus provided within an intracorporeal treatment area includes a mechanical sensor, a stimulator, and a processor. The processor is configured to provide a periodic stimulus via the stimulator, and monitor the output from the mechanical sensor in an expected response window that follows one stimulus, yet concludes before the application of the next, subsequent stimulus to determine if the stimulus induced a response of the muscle.

The carrier material is operative to be secured around a portion of the limb, and each of the plurality of mechanical sensors are coupled with the carrier material. Each mechanical sensor is positioned on the carrier material such that it is operative to monitor a mechanical response of a different muscle group of the limb. Each mechanical sensor then generates a respective mechanomyography output signal corresponding to the monitored mechanical response of its adjacent muscle group. These signals may then be communicated outbound from the device via communication circuitry provided on the device.

A neural monitoring system for detecting an artificially-induced mechanical muscle response to an electrical stimulus at a stimulation frequency includes a mechanical sensor and a processor in communication with the mechanical sensor. The mechanical sensor is configured to be placed in mechanical communication with the muscle and to generate a mechanomyography output signal corresponding to a sensed mechanical movement of the muscle. The processor is configured to receive the mechanomyography output signal from the mechanical sensor and determine a frequency component of the mechanomyography output signal that has a peak magnitude and to detect the occurrence of an artificially-induced mechanical muscle response therefrom.
