Ultrasound-guided shoulder injections for frozen shoulder

Effectiveness of USG-Guided Shoulder Injections as an Adjunct to a Home Exercise Program in the Conservative Management of Painful Frozen Shoulder and Its Association With Pain Phenotypes

Not applicable Interventional Konya Beyhekim Training and Research Hospital · NCT07493213

This tests whether adding ultrasound-guided suprascapular nerve block, with or without a subacromial injection, to a home exercise program reduces pain and improves shoulder function in adults with chronic frozen shoulder.

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.

Who should consider this trial

Good fit: Adults aged 18–75 with primary frozen shoulder lasting at least three months, pain ≥4/10 on VAS, and ≥30° restriction in two planes who can follow a home exercise program and consent to participate.

Not a fit: Patients with secondary shoulder problems such as rotator cuff tear, significant arthritis, prior shoulder surgery, neurological disorders, or systemic/inflammatory rheumatic disease are unlikely to benefit from the interventions tested here.

Why it matters

Potential benefit: If successful, adding targeted ultrasound-guided injections to home exercises could provide faster pain relief and improved shoulder mobility for people with chronic frozen shoulder.

How similar studies have performed: Prior studies of suprascapular nerve blocks and subacromial injections have shown mixed short-term pain relief, but durable functional benefits for adhesive capsulitis remain uncertain.
