Subacromial corticosteroid injection on poststroke hemiplegic shoulder pain: a randomized, triple-blind, placebo-controlled trial.

Objective: To evaluate the effect of subacromial corticosteroid injection on hemiplegic shoulder pain (HSP).

Design: Multicenter, randomized, triple-blind, placebo-controlled trial.

Setting: Three primary and 1 university-affiliated tertiary-care hospitals.

Comparison of high- and low-dose corticosteroid in subacromial injection for periarticular shoulder disorder: a randomized, triple-blind, placebo-controlled trial.

Objective: To determine whether subacromial injection with high-dose corticosteroid in patients with periarticular shoulder disorders is better than low-dose corticosteroid or placebo in improving pain, function, and active range of motion (AROM).

Design: Multicenter, randomized, triple-blind, placebo-controlled trial.

Setting: Primary (n=2) and university-affiliated (n=1) tertiary-care hospitals.
