Adhesive capsulitis, or “frozen shoulder,” is a painful condition that progresses through three phases: freezing, frozen, and thawing. This study evaluated the efficacy of glenohumeral hydrodistension combined with physical therapy in 40 patients with adhesive capsulitis (23 in stage 1 and 17 in stage 2). Patients were assessed at baseline and at 2, 4, and 6 months post-treatment for range of motion, pain, and functionality. Results showed significant improvements in shoulder range of motion (except extension) and in pain and functionality scores. Phase 2 patients had more difficulty recovering from internal rotation. The study concluded that ultrasound-assisted hydrodistention with targeted exercise effectively improves pain relief, reduces disability, and increases range of motion, particularly when treatment begins before phase 2.
