ROC curve and Minimal Clinically Inportant Differences (MCID) analysis of normalized parameters.
| Gait parameter | AUC (95% CI) | MCID | % Se (95% CI) | % Sp (95% CI) | LR+ (95% CI) | LR− (95% CI) | PV+ (95% CI) | PV− (95% CI) | PPR (OR) | NPR (OR) |
|---|---|---|---|---|---|---|---|---|---|---|
| Δ Spatial asimmetry | 0.963 (0.840–0.998) | >25.56 | 94.74 (74.0–99.9) | 88.24 (63.6–98.5) | 8.05 (2.2–29.7) | 0.06 (0.009–0.4) | 90 (70.9–97.1) | 93.7 (68.8–99.0) | 90% (9.0) | 73% (2.7) |
| Δ Trunk rotation | 0.784 (0.616–0.903) | >9.00 | 95 (75.1–99.9) | 56.25 (29.9–80.2) | 2.17 (1.2–3.8) | 0.089 (0.01–0.6) | 73.1 (60.7–82.7) | 90 (55.9–98.5) | 6% (0.1) | 9% (0.1) |
Δ is equal to the difference between the value of each parameter after and before the rehabilitative treatment. The Area Under the ROC Curve (AUC), sensitivity (Se), specificity (Sp), positive (LR+), and negative Likelihood Ratio (LR−), positive (PV+) and negative Predictive Value (PV−), Positive Posterior Probability (PPR), and negative Posterior Probability (NPR) with corresponding Odds Ratios (OR) are reported.
