TABLE 5.

Means (SD) and ranges for glenohumeral joint internal and external rotation range of motion across the 3 posterior shoulder tissue conditions, measured with the humerus elevated to 60° in the scapular plane.

	Internal Rotation	External Rotation
Muscle
Mean	15.8º (9.2°)	102.5° (15.1°)
Range	0°– 33°	68°– 119°
Baseline
Mean	23.4° (14.2°)^*	105.5° (16.7°)
Range	2°– 49°	68°– 121°
Contracted
Mean	18.0° (7.6°)	107.9° (18.4°)
Range	3°– 25°	68°– 128°

Statistically significant difference in internal rotation compared to muscle condition.
