Summary

Frozen shoulder causes pain and stiffness. A common treatment called hydrodistension injects fluid into the shoulder joint to stretch it, but it can be painful. This study tests whether giving a nerve block first can reduce that pain and improve results. Fifty adults with frozen shoulder will be randomly assigned to get hydrodistension alone or with a nerve block, and their pain and mobility will be tracked for three months.

What this could mean

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

Active substance
suprascapular nerve block with local anesthetic
What this could lead to
If it works, this could make a common frozen shoulder treatment less painful and more effective, improving comfort and recovery.
What could go wrong
This is a small, early-stage trial with only 50 participants. The nerve block may not reduce pain enough to matter, and results may not apply to everyone.
