Abstract

|
|
Objective: To assess the relative effectiveness of three injections methods suprascapular nerve block (SSNB) alone, intra-articular steroid injection (IAI) alone, or both?on relief of hemiplegic shoulder pain.
Methods: We recruited 30 patients with hemiplegic shoulder pain after stroke. SSNB was performed in 10 patients, IAI in 10 patients, and a combination of two injections in 10 patients. All were ultrasonography guided. Each patient’s maximum passive range of motion (ROM) in the shoulder was measured, and the pain intensity level was assessed with a visual analogue scale (VAS). Repeated measures were performed on pre-injection, and after injection at 1 hour, 1 week, and 1 month. Data were analyzed by Kruskal-Wallis and Friedman tests.
Results: All variables that were repeatedly measured showed significant differences in shoulder ROM with time (p<0.05), but there was no difference according injection method. In addition, VAS was statistically significantly different with time, but there was no difference by injection method. Pain significantly decreased until a week after injection, but pain after a month was relatively increased. However, pain was decreased compared to pre-injection.
Conclusion: The three injection methods significantly improved shoulder ROM and pain with time, but no statistically significant difference was found between them.
