Can radiofrequency waves unfreeze a stiff shoulder?
NCT ID NCT07788287
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This trial tests whether adding TECAR therapy—a device that delivers gentle radiofrequency energy to warm deep shoulder tissues—to standard stretching exercises helps people with frozen shoulder (adhesive capsulitis) move their shoulder more easily. About 60 adults aged 40 to 65 with stage 2 or 3 frozen shoulder will be split into two groups: one gets stretching alone, the other gets TECAR plus stretching. Researchers will measure changes in shoulder range of motion, pain, and daily function to see if the added therapy makes a meaningful difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transfer of Energy Capacitive and Resistive (TECAR) therapy, a device-based treatment using radiofrequency energy to heat deep tissues, combined with stretching exercises.
- What this could lead to
- If effective, TECAR therapy could become a standard addition to stretching for frozen shoulder, helping people regain movement and reduce pain without surgery.
- What could go wrong
- This is a small, early-stage trial, and results may not apply to everyone. TECAR therapy is generally safe but may cause discomfort or skin irritation, and its benefit over stretching alone is not yet proven.
