Max CMAP Amplitude (Mean)

The maximum Compound Motor Action Potential (CMAP) is a measurement obtained through EMG testing that is associated with disease progression. In this study, we measure the maximum CMAP by stimulating one nerve in the hand and measuring the response of the muscle. This is done multiple times, the outcome used is the highest peak, or response observed. (NCT00227266)

In this study, we measure the maximum CMAP by stimulating one nerve in the hand and measuring the response of the muscle. This procedure is repeated multiple times. The maximum area is the response that results in the largest area under the response curve. (NCT00227266)
