Mean (Standard Deviation) Rotations at Upper and Lower Ranges of Humerothoracic Elevation and Mean Change (95% Confidence Interval) Between the Traditional and Modified Hand Positionsa

  • a ATPT (−/+)=scapular anterior/posterior tilt, where the negative sign indicates less anterior tilt, and the positive sign indicates more posterior tilt; IRER (+/−)=internal rotation/external rotation, where the positive sign indicates more internal rotation, and the negative sign indicates less external rotation; URDR (−/+)=upward rotation/downward rotation, where the negative sign indicates less upward rotation, and the positive sign indicates more downward rotation; and GHIRER (+/−)=glenohumeral internal rotation/external rotation, where the positive sign indicates more internal rotation, and the negative sign indicates less external rotation. Green font indicates modified position resulted in a favorable kinematic change. Red font indicates modified position resulted in a detrimental kinematic change. An asterisk (*) indicates a clinically meaningful change. When a significant interaction effect for exercise and hand position occurred, a dagger () indicates a pair-wise difference where the modified hand position resulted in improved kinematics over the traditional hand position.
