| Differences | ||
| Internal rotation a,b | −14.5 (9.7) | −32.7 (13.4) |
| Total arc of motion a,c | −6.7 (11.1) | −28.3 (13.1) |
a
Statistically significant.
b
Internal rotation difference was calculated by the following formula: dominant arm internal rotation – nondominant arm internal rotation.
c
Total arc of motion difference was calculated by the following formula: dominant arm total arc of motion – nondominant arm total arc of motion.
