Comparison of physiotherapy, manipulation, and corticosteroid injection for treating shoulder complaints in general practice: randomised, single blind study Jan C Winters, Jan S Sobel, Klaas H Groenier, Hans J Arendzen, Betty Meyboom-de Jong Abstract Objective: To compare the efficacy of physiotherapy, manipulation, and corticosteroid injection for treating patients with shoulder complaints in general practice. Design: Randomized, single blind study. Setting: Seven general practices in the Netherlands. Subjects: 198 patients with shoulder complaints, of whom 172 were divided, on the basis of physical examination, into two diagnostic groups: a shoulder girdle group (n=58) and a synovial group (n=114). Interventions: Patients in the shoulder girdle group were randomized to manipulation or physiotherapy, and patients in the synovial group were randomized to corticosteroid injection, manipulation, or physiotherapy. Main outcome measures: Duration of shoulder complaints analyzed by survival analysis. Results: In the shoulder girdle group duration of complaints was significantly shorter after manipulation compared with physiotherapy (P<0.001). Also the number of patients reporting treatment failure was less with manipulation. In the synovial group duration of complaints was shortest after corticosteroid injection compared with manipulation and physiotherapy (P<0.001). Drop out due to treatment failure was low in the injection group (17%) and high in the manipulation group (59%) and physiotherapy group (51%). Conclusions: For treating shoulder girdle disorders, manipulation seems to be the preferred treatment. For the synovial disorders, corticosteroid injection seems the best treatment.
