In addition to ultrasound, measurements of range of motion will be performed at each testing session. Motions to be tested will be: shoulder flexion, extension, abduction, internal rotation, and external rotation; elbow flexion and extension; wrist flexion and extension; hip flexion, extension, abduction, internal rotation, and external rotation; knee flexion and extension. Recent studies have found significant results for deficits in range of motion correlating to UCL tears, so this data will be used in conjunction with measurements of laxity of the UCL as seen with ultrasound.
