Do Scapular Kinematics Alter During The Performance Of The Scapular Assistance Test And Scapular Retraction Test: A Pilot Study, W. Ben Kibler, Thomas J. Cunningham, Natalie L. Myers, Timothy L. Uhl

Physical Therapy Faculty Publications

Objective: To describe to what degree and in what plane biomechanical alterations occur during the performance of the Scapular Retraction test (SRT) and Scapular Assistance Test (SAT).

Design: Laboratory Pilot Study

Participants: Eight symptomatic and 7 asymptomatic subjects were instrumented with electromagnetic sensors.

Main Outcome Measures: The SRT and SAT were performed with the scapula stabilized and unstabilized. The scapular kinematic variables of posterior tilt, internal rotation, upward rotation, protraction, and elevation were measured during both tests.

Results: Descriptive analysis of scapular kinematics suggested that posterior tilt was primarily increased during both clinical tests in both groups. Both groups decreased …
