Immobilization following median and/or ulnar nerve repairs results in strength loss in the wrist and finger extensor muscles. Given the critical importance of wrist extension for functional grip, this condition significantly restricts hand functions. Therefore, this study aims to investigate the effects of EMG-triggered electrical stimulation applied to the wrist and finger extensors, in addition to conventional physiotherapy, on functional outcomes in patients undergoing median and/or ulnar nerve repair, with the objective of restoring extensor muscle weakness induced by immobilization.
