Abstract__ Detecting acute nerve compression using neurophysiologic studies is an important part of the practice of clinical intra-operative neurophysiology. The goal of this paper was to study the changes in the compound muscle action potential CMAP during acute mechanical compression. This is the type of injury most likely to occur during surgery. Thus understanding the changes in the CMAP during this type of injury will be useful in the detection and prevention using intra-operative neurophysiologic monitoring. The model involved compression of the hamster sciatic nerve over a region of mm with pressures up to 2000 mmHg for times on the order of 3 minutes. In this model
