In order to elucidate strict actions of the human wrist flexors, motion and force produced by electrical neuromuscular stimulation (ENS) to each of musculus (m.) flexsor carpi radialis (FCR) and m. flexsor carpi ulnaris (FCU) with the prone, semiprone, and supine forearm were studied in ten healthy human subjects.


The force study results suggest that FCU is a flexor rather than an adductor with every forearm position. FCR should be a flexor rather than an abductor with the prone and semiprone and a flexor with the supine forearm. The action of FCR as the abductor should diminish with supinating the forearm.
