Abstract:
Background Shoulder pain is one of the most common complaints of hemiplegic patients after stroke, affecting their daily activity and quality of life.
Objective To analyze the factors related to shoulder contracture in stroke patients with hemiplegic shoulder pain.
Methods From October 2013 to December 2019, 66 patients with hemiplegic shoulder pain (HSP) were recruited in the department of rehabilitation in the First Medical Center of Chinese PLA General Hospital. Of the 66 cases, there were 46 males and 20 females with average age of (57.28 ± 12.08) years. MRI scanning was performed on the affected shoulder, and clinical characteristics were recorded. The patients were divided into contracture group (n=35) and non-contracture group (n=31), and indexes were compared between the two groups.
Results MRI results showed that 59 cases (89.39%) had subscapular bursitis/joint cavity effusion, 54 cases (81.82%) had supraspinatus tendon injury, 54 cases (81.82%) had biceps tendinitis, 50 cases (75.76%) had subacromial deltoid bursitis, and 57 cases (86.36%) had subcococoid bursitis. The incidences of subacromial deltoid bursitis and labrum injury in the joint contracture group were higher than those in the non-joint contracture group (85.71% vs 64.51%, P=0.050; 62.86% vs 35.48%, P=0.026). No significant difference was found in other indexes between the two groups.
Conclusion Subscapular bursitis/joint cavity effusion, supraspinatus tendon injury and biceps tendinitis are the most common MRI changes in patients with HSP. HSP patients with shoulder contracture are more prone to have subacromial deltoid bursitis and glenoid lip injury.
