TABLE 1.

Trial-to-trial variability of hip and knee angles at peak knee flexion.

		ICC_(3,1)	SEM(°)
Hip	Frontal	0.89	2.0
	Transverse	0.95	1.3
Knee	Sagittal	0.81	3.5
	Frontal	0.98	1.0
	Transverse	0.94	1.4

Abbreviations: ICC, intraclass correlation coefficient; SEM, standard error of measurement, SEM = $σ \cdot \sqrt{1 - I C C_{(3, 1)}}$ where σ is the pooled standard deviation of the 3 trials.
