Frozen shoulder showdown: which treatment wins?
NCT ID NCT07409779
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two common treatments for frozen shoulder (adhesive capsulitis): a procedure that stretches the shoulder joint capsule (capsular distension) and a steroid injection. Both are followed by a rehab program. The trial will measure pain, movement, and disability in 50 adults aged 18-80 to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Betamethasone (Diprostene®) injection and capsular distension procedure
- What this could lead to
- If this trial succeeds, it could show which treatment—capsular distension or steroid injection—works better for frozen shoulder, helping doctors choose the best option.
- What could go wrong
- This is a small, early-stage trial with only 50 people, so results may not apply to everyone. Both treatments have risks like infection or temporary pain, and one may not be clearly better.
