Summary

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.

Conditions

  • Peripheral Nerve Injuries
  • Median Nerve Injury
  • Ulnar Nerve Injury

Interventions

OTHER

EMG-triggered electrical stimulation

This group will receive EMG-triggered electrical stimulation therapy in addition to conventional physiotherapy in the 5th week.The EMG-triggered electrical stimulation protocol will be conducted over 12 sessions (3 days/week for 4 weeks). Surface electrodes will be placed parallel to the fibers of the wrist and finger extensors-specifically the EDC, ECRL/B, and ECU-using anatomical landmarks and palpation. Following a baseline calibration (5s contraction/10s rest) to establish a microvolt threshold, the device will require active cognitive participation from the patient to initiate stimulation. Once the threshold is exceeded, stimulation will be delivered at 60 Hz with a 300 µS pulse width and 0.5s ramp times. The procedure involves 10 repetitions per muscle, utilizing a 10s contraction and 30s rest cycle to enhance functional recovery.

OTHER

Conventional physiotherapy group

The conventional physiotherapy program will comprise splinting, edema control, range of motion exercises, and resistance training.
