Experiment setup. a Surface electrode placement on forearm muscles. b Initial wrist position. c Wrist movements. d The muscles activity of wrist extension consist of extensor digitorum (ED), flexor pollicis longus (FPL), extensor carpi ulnaris (ECU), abductor pollicis longus (APL), pronator teres (PT), and supinator (Sup) for 10 times repetition. e Test paradigm which the recording protocols were carried out according to it
