Ultrasound-guided shoulder injections for frozen shoulder

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, randomized trial enrolling 68 adults (age 18–75) with chronic primary frozen shoulder refractory to routine analgesics. All participants follow a standardized home-based exercise program and are randomized to receive either an ultrasound-guided suprascapular nerve block alone or the same nerve block combined with a subacromial injection. Outcomes include pain intensity (VAS) and function (SPADI), measured at baseline and over a 20-week follow-up. Clinical and imaging exams are used to confirm diagnosis and exclude alternate shoulder pathology prior to enrollment.

• Comparing different NSAIDs plus home exercises for frozen shoulder

  This will test whether taking one of several NSAIDs (diclofenac, meloxicam, or indomethacin) together with home shoulder exercises helps adults aged 18–75 with frozen shoulder and whether pain type changes the benefit.
