Actual (reported)This prospective observational study examined muscle structure, stiffness, and activation in adults aged 40 to 70 years with unilateral adhesive capsulitis. Thirty-two participants completed a single assessment of both shoulders using ultrasound, shear-wave elastography, surface electromyography, and shoulder-function questionnaires. The affected shoulder was compared with the asymptomatic contralateral shoulder, and affected-side findings were compared between pain-dominant (freezing) and stiffness-dominant (frozen) phases. The study did not assign a treatment or intervention.

Actual (reported)Side-to-Side Difference in Muscle Thickness
Ultrasound muscle thickness (cm) in the supraspinatus, infraspinatus, teres minor, and anterior, middle, and posterior deltoid; compare the affected shoulder with the asymptomatic contralateral shoulder.
Baseline (single assessment at the initial study visit)
Side-to-Side Difference in Fascicle Length
Ultrasound fascicle length (cm) in the supraspinatus, infraspinatus, teres minor, and anterior, middle, and posterior deltoid; compare the affected shoulder with the asymptomatic contralateral shoulder.
Baseline (single assessment at the initial study visit)
Side-to-Side Difference in Physiological Cross-Sectional Area
Ultrasound-derived physiological cross-sectional area (PCSA; cm²) for the supraspinatus, infraspinatus, teres minor, and deltoid subregions; compare the affected shoulder with the contralateral shoulder.
