Reliability test.

Side	Parameter	ICC (95% CI)	SEM	MDC
Left	Muscle tone	0.94 (0.89–0.96)	0.53	1.47
	Stiffness	0.94 (0.90–0.97)	18.12	50.23
	Logarithmic decrement	0.90 (0.83–0.95)	0.09	0.25
Right	Muscle tone	0.92 (0.85–0.95)	0.59	1.64
	Stiffness	0.95 (0.90–0.97)	17.03	47.20
	Logarithmic decrement	0.94 (0.89–0.96)	0.07	0.19

Note. SEM = SD ∗ √(1–ICC); MDC₉₅ = 1.96 ∗ √2 ∗ SEM. ICC: intraclass correlation coefficient; MDC: minimum detectable change; and SEM: standard error of measurement.
