Comments
Intraclass correlation coefficients were high for intratester
(0.93, SEM 1.64 degrees) and intertester (0.91, SEM
1.71 degrees) measurements. This measurement was also shown to have a moderate to good relationship with lost internal shoulder
rotational motion (r = .72, P< .001) of the dominant arm
among the baseball pitchers.
