Outcomes of rectus femoris transfer in patients with cerebral palsy with stiff knee gait comparing low, moderate, and high peak knee flexion (PKF), knee ROM (KROM), and time to peak knee flexion (TiPKF)
| Evaluation cycle |
PKF (mean, SD) | KROM (mean, SD) | Ti PKF (mean, SD) | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Low | Moderate | High | Low | Moderate | High | Low | Moderate | High | |
| Baseline | 49.69 ± 7.36 | 60.62 ± 1.46 | 73.54 ± 6.12 | 36.19 ± 6.95 | 49.14 ± 1.99 | 65.92 ± 9.35 | 74.19 ± 5.27 | 81.56 ± 0.90 | 86.87 ± 3.42 |
| < 3 years | 63.43 ± 10.01 | 71.55 ± 10.98 | 72.04 ± 7.74 | 45.18 ± 15.50 | 54.97 ± 10.26 | 58.63 ± 11.90 | 77.22 ± 4.65 | 80.60 ± 4.58 | 82.59 ± 4.45 |
| > 7 years | 60.77 ± 7.53 | 65.29 ± 7.32 | 64.37 ± 12.75 | 41.09 ± 12.04 | 46.41 ± 7.38 | 54.93 ± 14.10 | 77.27 ± 5.64 | 77.64 ± 4.79 | 81.98 ± 4.88 |
Low PKF group: F(2) = 44.49, p < 0.001, moderate PKF group: F(2) = 7.69, p = 0.002, high PKF group: F(1.71) = 15.21, p < 0.001; low KROM group: F(2) = 7.5, p < 0.001, moderate KROM group: F(2) = 3.64, p = 0.05, high KROM group: F(1.87) = 14.81, p < 0.001; low TiPKF group: F(2) = 6.15, p = 0.003, moderate Ti PKF group: F(2) = 3.43, p = 0.05, high Ti PKF group: F(2) = 36.06, p < 0.001; the F is the test statistic for the repeated measure analysis of variance model, whereas the value within the parenthesis is the degree of freedom.
