Official title
The Impact of EMG-Triggered Electrical Stimulation of Extensor Muscles on Functional Status Following Median and/or Ulnar Nerve Repairs: A Single-Blind, Randomized Controlled Study
Overview
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.
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 thresh - Other Conventional physiotherapy group
The conventional physiotherapy program will comprise splinting, edema control, range of motion exercises, and resistance training.
Primary outcome measures
- Manual muscle test [Time frame: At 12 and 24 weeks after surgery.]
Secondary outcome measures (2)
- Gross and fine grip strength measurements by hand dynamometry and pinch gauge (kg) [Time frame: At 12 and 24 weeks after surgery.]
- Assessment of hand function via Michigan Hand Outcomes Questionnaire [Time frame: At 12 and 24 weeks after surgery]
