OBJECTIVE: To determine the effects of scapular mobilization on function, pain, range of motion, and satisfaction in patients with subacromial impingement syndrome (SAIS). DESIGN: Randomized, double-blind, placebo-controlled clinical trial. SETTING: University hospital clinics in Turkey. PARTICIPANTS: 66 participants (mean +/- SD age 52.06 +/- 3.71 y) with SAIS. INTERVENTIONS: Participants were randomized into 3 groups: scapular mobilization, sham scapular mobilization, and supervised exercise. Before the interventions transcutaneous electrical stimulation and hot pack were applied to all groups. Total intervention duration for all groups was 3 wk with a total of 9 treatment sessions. MAIN OUTCOME MEASURES: Shoulder function and pain intensity were primary outcome measures; range of motion and participant satisfaction were secondary outcome measures. Shoulder function was assessed with the short form of the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH). A visual analog scale was used to evaluate pain severity. Active range of motion was measured with a universal goniometer. A 7-point Likert scale was used to evaluate satisfaction. Outcome measurements were performed at baseline, before visits 5 and 10, 4 wk after visit 9, and 8 wk after visit 9. RESULTS: There was no group difference for DASH score (p = 0.75), pain at rest (p = 0.41), pain with activity (p = 0.45), pain at night (p = 0.74), and shoulder flexion (p = 0.65), external rotation (p = 0.63), and internal rotation (p = 0.19). There was a significant increase in shoulder motion and function and a significant decrease in pain across time when all groups were combined (p < 0.001). The level of satisfaction was not significantly different for any of the questions about participant satisfaction between all groups (p > 0.05). CONCLUSION: There was not a significant advantage of scapular mobilization for shoulder function, pain, range of motion, and satisfaction compared with sham or supervised-exercise groups in patients with SAIS.
