Fig. 3: The receiver operating characteristics (ROC) curves for the gait metrics with the best discriminative value between Parkinson’s Disease (PD) subtypes and healthy controls (HC), as well as between tremor-dominant (TD) and postural instability and gait disorder (PIGD) subtype.

The ROC curves for the gait metrics with the best discriminative value between a TD and HC; b PIGD and HC; c TD and PIGD. AUC value is reported for each curve. MAS more affected side, LAS less affected side, RoM range of motion, SiSt sit to stand. Note, if the same gait parameter showed significantly discriminative ability in both MAS and LAS limbs, only the side with higher AUC value was selected.
