Adhesive capsulitis is a common and disabling shoulder condition characterized by pain and progressive limitation of range of motion. Capsular distension and intra-articular corticosteroid injection are commonly used therapeutic options, often combined with rehabilitation, but their comparative effectiveness remains debated.
The objective of this randomized controlled trial is to compare the efficacy and tolerance of ultrasound-guided capsular distension combined with rehabilitation versus intra-articular corticosteroid injection combined with rehabilitation in patients with adhesive capsulitis.
Outcomes will include shoulder pain, range of motion, functional disability, patient satisfaction, and procedure-related complications, assessed at short, mid, and long-term follow-up.
