63 patients were randomized to determine the effect of varying doses of corticosteroid injections in the treatment of adhesive capsulitis. Participants were allocated to groups of high-dose triamcinolone (40mg), low-dose triamcinolone (20mg), or placebo (control) (1% lidocaine). Results after 12 weeks indicated that pain and disability were more significantly improved with both dosages of corticosteroid compared to control, but there was no difference between 20mg and 40mg triamcinolone. Corticosteroid injections also had a beneficial effect on passive range of motion in flexion, abduction, and internal rotation
