Could a simple buzz loosen stiff legs? small trial puts vibration therapy to the test
NCT ID NCT07447934
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a wearable device that vibrates leg muscles to reduce spasticity (stiffness) and improve walking. Twenty-five people with spasticity from a neurological condition will use the device for 15–60 minutes in the lab and at home. Researchers will measure muscle activity, joint flexibility, and walking speed to see if the vibration helps and where on the body it works best.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vibrotactile stimulation device
- What this could lead to
- If it works, this could offer a non-invasive, drug-free way to ease muscle stiffness and improve walking for people with spasticity.
- What could go wrong
- This is a very small early study (25 people) with no control group. It is testing basic questions like where to place the device, so results may not lead to a proven treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * ≥6 months following neurologic diagnosis leading to spasticity * Modified Ashworth Scale (MAS) score of 3 or lower on ankle plantar flexor. * Ability to stand (with or without assistance) and lie supine. * Able to understand and comply with study procedures. Exclusion Criteria: * Uncontrolled systemic illness or serious medical conditions that could interfere with study procedures. * Previous surgery to treat spasticity in the affected lower limb. * Prior Botulinum Toxin (BoNT) therapy in the target limb within 4 months. * Unstable medication regimens for spasmolysis or muscle relaxation. * Participation in tone-related treatments (e.g., physiotherapy, TENS, acupuncture) within 4 weeks prior to baseline. If ongoing treatment started more than 4 weeks before baseline, it should remain consistent throughout the study
