Figure 4

Schematic outline for relating outcome measures to pathophysiological mechanisms. We expect to identify one or more of the hypothesized etiological mechanisms in each SIS patient. These mechanisms might be related to the reported variations in SIS symptoms, course, and treatment outcome. (MRI = Magnetic Resonance Imaging, X-ray & EMG task = radiographs during EMG recorded abduction and adduction tasks for measurements of acromiohumeral distance, and FoB = 3D kinematics with Flock of Birds system).
