| Foot pressure | Normal | Ponseti | Operative | ||
|---|---|---|---|---|---|
| Parametric comparison | Mean ± SD | Mean ± SD | Mean ± SD | F (df) | p-value |
| Coronal plane pressure index (varus −/valgus +) | 11.0 ± 23.6 | −15.7 ± 18.9*a,b | −36.8 ± 24.7*a | 50.6 (2) | <0.0001 |
| Heel impulse | 37.3 ± 9.6 | 42.2 ± 16.0*b | 32.2 ± 14.4 | 5.4 (2) | 0.006 |
| Medial forefoot pressure | 33.5 ± 9.2 | 39.8 ± 11.9*a,b | 19.1 ± 8.8*a | 45.5 (2) | <0.0001 |
| Non-parametric comparison | M (IQR) | M (IQR) | M (IQR) | χ2 | p-value |
| Lateral midfoot pressure | 5.3 (5.6) | 23.7 (11.2)*a | 25.0 (13.8)*a | 66.5 (2) | <0.0001 |
*p < 0.01; adifferent from normal; bdifferent from operative; F = ANOVA value; χ2 = Chi-squared value for Kruskal–Wallis test; M median, IQR interquartile range
