In isokinetic muscle testing of the shoulders of 31 normal volunteers, no statistical difference was found between dominant and nondominant shoulders, even though there was a consistent pattern of greater strength in the dominant shoulder. Internal rotation strength was greater than external rotation (p < 0.01) by the ratio of 3:2 for both the fast and slow torque arm speed. Extension strength was greater than flexion (p < 0.01) by a ratio of 5:4 at both speeds. Abduction strength was greater than abduction (p <0.01) by a ratio of 2:1 for both speeds. Overall, abduction strength was greatest, followed by extension, flexion, abduction, internal rotation, and external rotation. Male strength was greater than female, but the advantage decreased when normalized for lean body mass and exercise habit.
