Table 2. Comparison of knee and hip muscle strength between the successful and unsuccessful groups during SLST 20.

Muscle strength	Successful (n=47)	Unsuccessful (n=19)
Knee flexion (Nm/kg, 60°/s)*	1.28 ± 0.26	0.99 ± 0.23
Knee extension (Nm/kg, 60°/s)*	2.52 ± 0.48	2.11 ± 0.31
Hip flexion (Nm/kg, 30°/s)*	1.55 ± 0.40	1.33 ± 0.21
Hip extension (Nm/kg, 30°/s)	1.95 ± 0.51	1.73 ± 0.51
Hip abduction (Nm/kg, 30°/s)	1.44 ± 0.35	1.34 ± 0.39
Hip adduction (Nm/kg, 30°/s)*	1.19 ± 0.34	1.05 ± 0.50

Data are presented as the mean ± standard deviation. *p<0.05.

SLST20: single-leg sit-to-stand test from a 20-cm box; Nm/kg: Newton meter per kilogram; °/s: degrees per second.
