Sound waves aim to loosen tight muscles in spinal cord injury
NCT ID NCT07501429
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tests whether focused shockwave therapy can safely reduce arm spasticity in people with spinal cord injury. Twelve participants will receive three weekly sessions of sound waves applied to the forearm and elbow muscles. Researchers will measure changes in muscle stiffness, range of motion, and quality of life to see if a larger trial is warranted.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- focused extracorporeal shockwave therapy (f-ESWT)
- What this could lead to
- If it works, this could offer a non-invasive, side-effect-free option to reduce arm spasticity and improve function and quality of life in people with spinal cord injury.
- What could go wrong
- This is a very small, early-phase pilot study with only 12 participants. It is designed to test feasibility, not prove effectiveness. The treatment may not reduce spasticity significantly, and results may not apply to everyone with spinal cord injury.
