Although a relationship has been reported between stroke and adhesive capsulitis, it is controversial whether the underlying cause of the capsular changes seen in hemiplegic shoulder pain is true adhesive capsulitis. Although there has been a limited number of studies, ultrasound, which has been reported as a sensitive and specific method in the diagnosis of true (idiopathic) adhesive capsulitis, has not yielded similar results to arthrography and MRI in demonstrating fibrotic and adhesive changes in the glenohumeral capsule in stroke patients with hemiplegic shoulder pain. This study aims to investigate ultrasonographic structural changes that may be associated with adhesive capsulitis in subacute stroke patients with painful and stiff hemiplegic side shoulder.
