Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Subacromial Impingement Syndrome (SIS) is a pathology resulting from mechanical repetitive compression and inflammation of the supraspinatus tendon, subacromial bursa and biceps tendon under the acromion and the coracoacromial ligament. It is the most common cause of shoulder pain, with an incidence of 44-65%. Restriction of the range of motion, along with the pain in the anterior region of the shoulder, is the main reason for disability and decreased quality of life in patients with SIS. Physical exercises to improve the range of motion, strengthening, and flexibility is the main part of treatment. The subacromial-subdeltoid bursa corticosteroid injection is shown to decrease pain during the exercise program and increase participation in the treatment. This study aims to compare the effectiveness of a supervised exercise program and home-based exercise program after subacromial-subdeltoid bursa corticosteroid injection in patients with SIS.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subacromial Impingement Syndrome (SIS) is a pathology resulting from mechanical repetitive compression and inflammation of the supraspinatus tendon, subacromial bursa and biceps tendon under the acromion and the coracoacromial ligament. It was first described in 1972 by Neer. Neer described SIS as a progressive syndrome with three stages, beginning with chronic bursitis and proceeding to partial and complete tears of the supraspinatus tendon, which may extend to rupture of other parts of the rotator cuff and may also involve the long biceps tendon. SIS is one of the most common causes of shoulder pain and disability reasons in both primary and secondary care. It is characterized by functional impairment of shoulder resulted from the progressive limitation of both active and passive glenohumeral movements. Restriction of the range of motion (ROM) along with the pain in the anterior region of the shoulder that gets worse with arm elevation or overhead activities is the main reason for decreased quality of life in patients with SIS. Therapeutic exercise programs are commonly used treatment methods in relieving pain and improving ROM and muscle elasticity. It was shown that such programs are more effective in reducing pain and improving functional loss than placebo in both short- and long-term. However, the optimal exercise regimen with the variety, frequency, and intensity exercises is still unclear. It is also controversial if a supervised exercise program is superior to a prescribed home-based exercise program. An efficient exercise program should target all structures affected by subacromial impingement. Therefore, both supervised and home-based exercise programs must involve rotator cuff and scapular stabilizing muscle strengthening, stretching and active-assistive range of motion exercises and proprioceptive neuromuscular facilitation exercises. Corticosteroid injection into the subacromial-subdeltoid bursa is shown to increase participation, decrease pain during the exercise program, and found to be effective for symptomatic impingement. The analgesic effect provides significant improvement of functions mainly in the short-term. Therefore, some physicians prefer corticosteroid injections alone in the treatment of SIS. However, it was found that the combination of corticosteroid injection and exercise program is significantly superior to corticosteroid injections alone. Ultrasound-guided subacromial-subdeltoid bursa injections are shown to have better outcome results than blind injections for both pain and overall shoulder function. This study aims to compare the effectiveness of supervised exercise and home-based exercise programs after ultrasound-guided subacromial-subdeltoid bursa corticosteroid injection in patients with SIS.

Patients diagnosed with SIS will be included and randomized into two groups. Both groups will receive subacromial-subdeltoid bursa 1 ml (7 mg/ml) betamethasone and 4 ml of 0.5% bupivacaine injection. The injection will be performed ultrasound-guided while the patient is in a sitting position with the lateral approach. The first group will perform their exercises under the supervision of the physiotherapist in the hospital. The second group will be taken to the home-based exercise program in a brochure format. Thus, both groups will receive the same exercises every day.

The pain will be assessed with the Visual Analogue Scale (VAS), active and passive ROM will be measured with a goniometer before injection, immediately, first hour, third week, and third month after the injection. The quality of life will be evaluated by Short Form 36, and disability will be questioned by Shoulder Pain and Disability Index before injection and third week and third month after injection.
