Stretch device vs. physical therapy: which loosens a frozen shoulder?
NCT ID NCT05384093
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Researchers are comparing three ways to treat shoulder stiffness: physical therapy alone, the ERMI Shoulder Flexionater stretch device alone, and the device plus physical therapy. The trial includes people with frozen shoulder (adhesive capsulitis), people with stiffness after shoulder surgery, and people with stiffness after a procedure that releases the shoulder under anesthesia. The main goal is to see how much shoulder motion, pain, and daily function improve with each approach.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ERMI Shoulder Flexionater, a high-intensity shoulder stretch device, compared with physical therapy
- What this could lead to
- If the device helps, it could offer a home-based option for people with frozen shoulder or post-surgical stiffness, either on its own or alongside physical therapy.
- What could go wrong
- Stretching a stiff shoulder can be painful, and some people may not stick with the device. The trial may also show that the device works no better than physical therapy alone.
