Pill or stretch? study tests two ways to ease carpal tunnel pain
NCT ID NCT04285281
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether gabapentin pills or a simple physiotherapy hand stretch (nerve mobilization) can reduce pain and improve hand function in people with carpal tunnel syndrome. 126 adults with confirmed carpal tunnel took part. The goal was to see if either treatment works better than doing nothing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gabapentin (oral capsules) and median nerve neural mobilization (physiotherapy maneuver)
- What this could lead to
- If successful, this could point toward a non-surgical, drug-free physiotherapy option for easing carpal tunnel pain.
- What could go wrong
- This is a small, completed Phase 4 trial. Results may not apply to everyone, and gabapentin can cause side effects like dizziness or drowsiness.
