Can the efficacy of subacromial corticosteroid injection be improved using a single-session mobilization treatment in subacromial impingement syndrome? A randomized single-blind controlled trial

Abstract

Background/aim: The objective in this study is to assess the short-term effects of a single-session mobilization in addition to subacromial corticosteroid SACS injection in impingement syndrome.Materials and methods: The study was designed as a prospective randomized controlled single-blind, parallel group clinical trial. Patients totally 84 were divided randomly into two groups equally. Forty-two patients in Group 1 received mobilization and SACS injection, whereas 42 patients in Group 2 only received SACS injections. A single SACS injection was applied in all patients. Mobilization was administered as a single session right after SACS injection. Patient' evaluations were performed measuring active range of motion AROM , visual analogue scale VAS during activity and rest, and Disabilities of Arm, Shoulder, and Hand Score DASH prior to treatment and in the first and fourth weeks following the treatment.Results: Both groups showed significant improvement in terms of AROM, VAS, and DASH scores in each evaluation step P
