Abstract Objective To explore the ultrasonographic characteristics of hemiplegic shoulders and evaluate coracoacromial ligament displacement during passive motions with dynamic ultrasound. Methods A total of 31 patients who suffered from post-stroke hemiplegic shoulders for the first time underwent dynamic ultrasound examinations. The vertical displacement of the coracoacromial ligament was analyzed by the motion tracing program during the following passive assisted motions: forward flexion in the scapular plane, horizontal abduction in the axial plane,external rotation with the arm at 0° abduction , internal rotation with the arm at 0° abduction, internal rotation with the arm at 90° abduction, and internal rotation at the back. Results ①Twenty-eight cases(90.32%) of abnormal ultrasound results were found among these patients. The findings of ultrasound disclosed 22 cases of lesions of the long head of the biceps tendon and tendon sheath,1 case of dislocation of the long head tendon,13 cases of bursitis and bursa effusion,15 cases of rotator cuff injury, and 18 cases of shoulder subluxasion. Multiple lesions existed simultaneously in 23 cases. There was significant difference in the incidence of the disease compared to the contralateral shoulders (P<0.01).②The mean vertical displacement of the coracoacromial ligament during passive assisted motions was significantly different between hemiplegic shoulders and contralateral shoulders(P<0.01).At the same time,the mean vertical displacement of the coracoacromial ligament during forward flexion, horizontal abduction, internal rotation with the arm at 90° abduction, and internal rotation at the back was significantly different compared to external rotation with the arm at 0° abduction and internal rotation with the arm at 0° abduction(P<0.01). Conclusions Dynamic ultrasound can disclose lesions of the post-stroke hemiplegic shoulder and help observe the variations of vertical displacement of the coracoacromial ligament during passive assisted motions. It is recommended that patients avoid shoulder motions which are likely to cause subacromial impingement.
