NAITO, A., YAJIMA, M., FUKAMACHI, H., USHIKOSHI, K., SUN, Y.-J. and SHIMIZU, Y. Electromyographic (EMG) Study of the Elbow Flexors during Supination and Pronation of the Forearm. Tohoku J. Exp. Med., 1995, 175 (4), 285-288 - Activities of the elbow flexors during supination and pronation of the forearm in a normal human volunteer were studied by an electromyography (EMG). The volunteer performed the movement slowly or quickly holding elbow flexion at various angles with or without a load. The biceps brachii showed an increase and a decrease of EMG activities during supination and pronation, respectively. The brachialis and brachioradialis showed a reduction and an increment of EMU activities accompanied by an increase and a decrease of EMG activities in the biceps brachii, respectively. These findings seem to indicate that reciprocal contractions among the elbow flexors permit the biceps brachii to work for supination without an induction of elbow flexion.
