Can a simple Skin-Level electric pulse ease muscle stiffness in a rare neurological disease?
NCT ID NCT06012110
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This trial asks whether a single 30-minute session of transcutaneous electrical stimulation, applied to the back and abdomen, can reduce muscle spasticity and improve walking in people with primary lateral sclerosis (PLS). Participants will attend one clinic visit, receive the stimulation, and have their spasticity, reflexes, gait, and balance assessed before, immediately after, and 24 hours later. The study is small, enrolling only 6 ambulatory adults diagnosed with PLS, and aims to see if this non-invasive approach offers any measurable benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcutaneous electrical stimulation (a device placed on the skin of the back and abdomen)
- What this could lead to
- If effective, this non-invasive approach could offer a new way to reduce muscle stiffness and improve mobility in people with primary lateral sclerosis.
- What could go wrong
- This is a very small early-stage trial (6 participants) with a single session, so results may not be generalizable. The effect may be temporary, and individual responses can vary.
