Clinical efficacy of manipulation under brachial plexus block anesthesia for primary adhesive capsulitis of shoulder: a retrospective cohort study

MUA under brachial plexus block anesthesia is significantly more effective than standardized conservative treatment in restoring shoulder function, relieving pain, and accelerating return to normal activities in patients with primary adhesive capsulitis. The procedure demonstrates a favorable safety profile and high patient satisfaction, representing a valuable therapeutic option for conservative treatment failures. This study provides Level III evidence that MUA under brachial plexus block is superior to conservative treatment for primary adhesive capsulitis.
