Screw Driving Task, Stroke Rotation, EMG.
The present study investigated the effect of handle size (35mm and 40mm), grip type (loose grip and tight grip) and supine stroke rotation (30 ? , 45 ? and 60 ? ) on electromyography i.e. EMG activity of forearm muscles for a screwing task in an experimental simulation. The eight participants performed the screw driving task for a 2 minutes duration (supination). The EMG activities of forearm muscles were recorded during this task. The muscles selected for EMG recording were FCR, FCU, FDS and ECRB muscles. The results showed that the flexor muscles were more activated than extensor muscles. Among giving conditions, 40mm handle size using loose grip with 60 ? stroke was most comfortable.
