From: Acute nerve compression and the compound muscle action potential
(A) Changes in amplitude and area under the curve at various points during the compression and recovery cycles. (B) Changes in nerve conduction velocity and CMAP duration during the various stages of nerve compression. (C) Changes in CMAP onset latency, mean latency and latency variance during nerve compression and recovery. The data in this figure represent averages over all nerves. In each case, the error bars represent 95% confidence intervals or roughly 2 standards errors of the mean above and below the central value.
