Fig. 4

Convergent validity showing correlations between Finger-to-Nose Test (FNT) time and clinical variables (a, b) and results of discriminant validity analyses (c, d). Correlations between FNT-time and clinical impairment scores (a, Fugl-Meyer Assessment of the Upper Limb (FMA-UL); b, biceps spasticity score). c Sensitivity/Specificity decision (SSD) plot for time to perform the FNT. Sensitivity (triangles) and specificity (circles) values were plotted against total time to perform the FNT in seconds. The intersection of both curves (vertical dotted line) represents the cut-off time to perform the test (10.6 s) that discriminates between mild and moderate impairment. d Receiver Operating Characteristic (ROC) Curve illustrating the area under the curve (AUC), significance level (p value) and 95% confidence interval (95% CI). Diagonal line indicates a 50/50 ratio between sensitivity and specificity of the FNT-time measure
