Comparison of the knee joint muscle strengths in the AE and LE groups. (All the patients who performed this test underwent bilateral TKRA).
| Variable | Before | After | p-Value | |
|---|---|---|---|---|
| AE (n = 24) | Extension (Nm) | 32.396 ± 21.073 | 30.979 ± 20.618 | 0.660 |
| Flexion (Nm) | 20.867 ± 11.917 | 21.154 ± 11.600 | 0.874 | |
| LE (n = 8) | Extension (Nm) | 31.500 (20.925–62.850) | 29.150 (23.050–40.175) | 0.401 |
| Flexion (Nm) | 19.100 (11.315–31.825) | 23.750 (8.425–31.225) | 0.889 | |
| AE (n = 24) | Extension (Nm/kg) |
0.489 ± 0.332 | 0.462 ± 0.285 | 0.632 |
| Flexion (Nm/kg) |
0.319 ± 0.179 | 0.322 ± 0.166 | 0.931 | |
| LE (n = 8) | Extension (Nm/kg) |
0.498 (0.309–1.079) | 0.498 (0.412–0.636) | 0.674 |
| Flexion (Nm/kg) |
0.304 (0.175–0.528) | 0.413 (0.149–0.511) | 0.889 | |
AE, aquatic exercise; LE, land exercise. Values are expressed as the mean ± standard deviation or median (Q1–Q3). As the AE group showed normal distribution by the Kolmogorov–Smirnov test with weight, a paired t-test was performed. As the LE group showed non-normal distribution weight, the Wilcoxon signed-rank test was performed.
