Summary

This study tests whether a device that delivers high-frequency radiofrequency electrical currents (called TECAR) can reduce pain and improve movement in people with muscle injuries or low back pain. Researchers will measure pain, flexibility, and function before and after a single session, and again at 3 and 6 months. 200 participants with hamstring, quadriceps, or calf injuries, or low back pain, will be assigned to either the TECAR group or a control group.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Radiofrequency electrical current (TECAR device)
What this could lead to: If it works, this could offer a non-invasive, drug-free option for easing pain and improving flexibility in people with common muscle injuries or back pain.
What could go wrong: This is an early-stage study with no blinding, so results may be influenced by placebo effects. The device is already used in clinics, so the real-world impact may be modest.
