Values are presented as mean±standard deviation. Group A: sono-guided subacromial corticosteroid injection, Group B: control. Internal rotation was determined by measuring the highest spinal segment that the patient could reach with his or her thumb. To facilitate statistical analyses, the spinal segment level was converted into continuous numbers; T1–T12 were represented by 1 through 12, L1–L5 were represented by 13 through 17, and the sacrum was represented by 18.
