GH group: ultrasound-guided glenohumeral steroid injection, SA group: ultrasound-guided subacromial steroid injection. Δ: amount of improvement=follow-up measurement subtracted by the pre-injection (Pre) measurement.
FE: forward elevation, ROM: range of motion, ER: external rotation at side, IR: internal rotation at 90° of abduction, pVAS: pain visual analog scale, ASES: American Shoulder and Elbow Surgeons, Constant: Constant-Murley.
