Patients were assigned to two groups: Group-1 included patients who received US-guided subacromial corticosteroid injections; Group-2 included patients who underwent blind subacromial corticosteroid injections. The primary Outcome Measure was a Visual analog scale. Secondary Outcome Measures were Shoulder joint range of motion (ROM), Shoulder Pain and Disability Index (SPADI), The Shortened Disabilities of the Arm, Shoulder and Hand Questionnaire (Quick DASH).
Since pain is usually accompanied by a substantial effect on daily life that results in the extensive use of healthcare resources. In subacromial impingement syndrome, shoulder pain affects the quality of life negatively by affecting upper extremity functions and interrupting night sleep. It is very important to control the pain in order to reduce the loss to the labor force and prevent the pain from becoming chronic. Various physical treatment methods such as ultrasound, hot pack, transcutaneous electrical nerve stimulation, etc., and injections or medical agents are recommended. This study aimed to compare the effects of ultrasound (US)-guided in comparison to landmark guided subacromial corticosteroids injection on shoulder range of motion (ROM), pain, and functional status in patients with subacromial impingement syndrome (SAIS).
