Electric zaps to wrist muscles may speed hand recovery after nerve surgery

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether adding EMG-triggered electrical stimulation to standard physiotherapy can help people regain hand function after median or ulnar nerve repair. The stimulation activates wrist and finger extensor muscles weakened by post-surgery immobilization. Twenty-six participants will be randomly assigned to receive either the stimulation plus physiotherapy or physiotherapy alone, and hand strength and function will be measured.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- EMG-triggered electrical stimulation
- What this could lead to
- If it works, this could provide a way to recover hand strength and function more quickly after nerve repair surgery.
- What could go wrong
- This is a small early-stage trial with only 26 participants, so results may not apply broadly. The therapy is added to standard physiotherapy, so any benefit may be modest.
