Comparison Suprascapular Nerve Block and Subacromial Injection in Hemiplegic Shoulder Pain

Overview

Hemiplegic shoulder pain is the most common poststroke painful condition. Hemiplegic shoulder pain reduces range of motion (ROM) and hand function, resulting in limited daily life activity and decreased quality of life. In the literature, the effectiveness of suprascapular nerve block and subacromial injection in hemiplegia patients with shoulder pain has been previously evaluated, but these injection treatments have not been compared. Therefore, the aim of this study is to compare the effectiveness of suprascapular nerve block and subacromial injection on pain, shoulder (ROM), function and quality of life in hemiplegia patients with shoulder pain.

Patients will be randomly assigned Subacromial injection group or Suprascapular nerve block group In the suprascapular nerve block group, suprascapular nerve block will be performed with a MyLab60 model a high resolution 7-12-MHz linear probe ultrasonography device. After the suprascapular fossa will be observed by ultrasonography, a betamethasone dipropionate plus betamethasone sodium phosphate solution (6.43 mg / mL + 2.63 mg / mL; 1 mL), 0.5 % bupivacaine (2 mL) and physiological serum (2 mL) will be injected with an in-plane technique using a 22 gauge 90-mm injector. In the subacromial injection group, subacromial injection will be performed with a MyLab60 model a high resolution 7-12-MHz linear probe ultrasonography device. After the subacromial bursa will be observed by ultrasonography, a betamethasone dipropionate plus betamethasone sodium phosphate solution (6.43 mg/mL + 2.63 mg/mL; 1 mL), 2% lidocaine (2 mL) and physiological serum (2 mL) will be injected with an in-plane technique using a 21 gauge 38-mm injector. A home exercise program will be given both groups. The exercise program consisted of passive and active-assistive ROM exercises (3 sets daily, 20 times in each set).
