The Scapular Assistance Test Results in Changes in Scapular Position and Subacromial Space but Not Rotator Cuff Strength in Subacromial Impingement

摘要: Study Design Controlled laboratory study. Objectives To determine the effect of modified scapular assistance test (SAT) on 3-dimensional shoulder kinematics, strength, and linear measures subacromial space in patients with impingement syndrome (SAIS). Background Abnormal kinematics have been identified SAIS. Increased upward rotation posterior tilt, as induced manual using SAT, theorized to increase may alter strength. Methods Forty-two subjects (21 SAIS 21 controls) participated this The anterior outlet space, measured via acromiohumeral distance ultrasound images, motion analysis, were determined arm at rest, 45° 90° active elevation without SAT. A dynamometer was used measure isometric Full factorial mixed-model analyses varianc...
