Isokinetic knee muscle strength and lower-extremity performance tests for the injured leg, the non-injured leg and the difference (n=82)
| Injured leg | Non-injured leg | Difference | p Value | |
|---|---|---|---|---|
| PT knee extension (Nm) | 158±51 | 181±50 | 23 (17 to 28) | <0.001 |
| TW knee extension (Tw) | 791±253 | 879±237 | 88 (59 to 117) | <0.001 |
| PT knee flexion (Nm) | 85±26 | 88±25 | 3 (1 to 6) | 0.015 |
| TW knee flexion (J) | 474±175 | 498±165 | 24 (6 to 42) | 0.010 |
| OLH (cm) | 82±35* | 92±30 | 10 (6 to 13) | <0.001 |
| 6MTH (s) | 2.4 (2.0; 3.4)* | 2.2 (1.9; 2.9)* | 0.2 (0.0; 0.5) | <0.001 |
| Knee-bends in 30 s (n) | 26±10* | 28±10 | 2 (1 to 3) | <0.001 |
Values are presented as mean±SD, mean (95% CI) or median (IQR, q1;q3).
p Values were calculated using paired samples t tests; non-parametric test was used when data were not normally distributed.
*n=81.
6MTH, 6 m timed hop test; OLH, one-leg hop for distance; PT, peak torque; TW, total work.
