Intraclass correlation coefficient for muscle ultrasound parameters.

	Intraclass Correlation Coefficient	95% CI
		Lower Limit	Upper Limit
CSA of VL	0.988	0.849	0.998
MT of VL	0.994	0.948	0.999
FL of VL	0.971	0.752	0.995
PA of VL	0.948	0.577	0.990
CSA of LM left	0.970	0.854	0.994
CSA of LM right	0.994	0.974	0.999

Note: CI = Confidence interval; CSA—cross-sectional area; VL—vastus lateralis; MT—muscle thickness; FL—fiber length; PA—pennation angle; LM—lumbar multifidus.
