A method for detecting functional weakness.

A J McComas, S Kereshi, J Quinlan.   

Abstract

A simple electrophysiological method is described for detecting weaknes of psychiatric origin. The method involves the interpolation of a single indirect stimulus to a muscle during the course of a supposedly maximal voluntary contraction. Incomplete motor activation is revealed by the presence of a twitch superimposed on the recording of voluntary torque.
