The effect of passive movements of the elbow on biceps EMG reaction time (RT) was studied in 10 normal subjects. Each subject was required to perform a simple RT task, flexing the left elbow to a tone stimulus, under three different conditions: (1) during passive flexion (PFLX) of the elbow, (b) during passive extension (PEXT), and (c) without passive movements (STAT). A forearm-rotator was used to produce a constant movement with angular velocity of 20 deg/sec, and in each same angle of the elbow joint. Significant differences in mean EMG-RTs were found between the three conditions; the shortest EMG-RT of all was observed in the PFLX condition (77.0±15.0 msec), followed by that in STAT (93.1±11.8 msec) and lastly in PEXT (116±23.1 msec). Neurophysiological mechanisms underlying these phenomenon are discussed.
