Scapula Resting Position ^a

Scapula resting position, deg b	Dominant Scapula	Nondominant Scapula	Difference
Upward/downward rotation (X)	18.27 ± 4.83	17.71 ± 5.81	0.56 ± 3.59
Internal/external rotation (Y)	137.93 ± 5.14	139.57 ± 6.80	–1.64 ± 7.22
Anterior/posterior tilt (Z)	0.63 ± 9.84	–4.26 ± 9.51	4.89 ± 9.23

^a Data are reported as mean ± SD.

^bX position = upward rotation is positive; Y position = internal rotation is positive; Z position = anterior tilt is negative.
