What this Trial Is About
Frozen shoulder, also known as adhesive capsulitis, causes pain and limits shoulder movement, impacting daily activities. When conservative treatments like physical therapy or medications don't help, arthroscopic capsular release surgery is considered. This observational study focuses on evaluating the effects of a 360° capsular release technique, which includes releasing the inferior shoulder capsule near important nerves, to understand its impact on nerve function in patients with frozen shoulder. Participants will undergo a standard arthroscopic 360° capsular release surgery, involving careful dissection around the inferior capsule and coracoid region to treat adhesive capsulitis. The study will assess nerve function by performing electromyography (EMG) and nerve conduction studies (NCS) on the axillary and musculocutaneous nerves before surgery and again 12 weeks after. Clinical measures such as shoulder range of motion, pain levels, muscle strength, and functional shoulder scores will also be recorded. During the study, participants will have EMG and NCS assessments targeting specific muscles and nerves related to shoulder movement. Researchers will measure changes in nerve conduction velocity, motor latency, and muscle action potentials, alongside clinical outcomes like pain and mobility. These evaluations aim to provide objective data on how the surgery affects peripheral nerve function and overall shoulder recovery over a 12-week postoperative period.
