A system for assessing nerve health during spinal decompression surgery includes a stimulator, a mechanomyography sensor including an accelerometer, a display device, and a processor. The processor controls the stimulator to deliver a first electrical stimulus to a nerve prior to surgical decompression and a second electrical stimulus after surgical decompression.

The processor accesses a target threshold range indicative of adequate decompression. The processor then calculates a first deviation of the first stimulation threshold from the target threshold range and a second deviation of the second stimulation threshold from the target threshold range. A value representing a change in nerve function is computed, wherein the value is based on a comparison of the first deviation to the second deviation.
