The degree of MCP joint flexion in both hands showed moderate correlation with the MDS-UPDRS-III motor score (r = 0.518, P < 0.001), mainly related to ipsilateral rigidity and ipsilateral bradykinesia scores, and fair correlation with the Hoehn-Yahr stage.
Moreover, PD-Monitor scores in 97 PD patients with MDS-UPDRS FT bradykinesia and each PD subgroup (FT bradykinesia scored from 1 to 3) were all higher than that in NC.
Maximum percent improvement from baseline in finger-tapping speed (measure of bradykinesia) measured using KinesiaTM technology (as the primary end point) and change from baseline in the Movement Disorder Society's Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS-III) motor section scores (the preferred exploratory end point) were evaluated.
