Figure 1. Relationship Between the mRS and Impairment- and Function-Based Outcomes 90 Days After Stroke.

Figure 1

Each panel shows pairwise scatterplots and the Spearman ρ correlation between the modified Rankin Scale (mRS) and each impairment and function outcome measure: Fugl-Meyer Assessment of Upper Extremity (FMA-UE), grip strength (Grip), Box and Blocks Test (BBT), Nine Hole Peg (9-HP), Leg Motor (Leg), gait velocity (GV), Timed Up and Go (TUG), NIH Stroke Scale (NIHSS), Barthel Index (BI), Stroke Impact Scale-16 (SIS), and the first principal component of all variables (PCA-1). Best possible score appears on left side of each panel; worst possible score appears on the right side for all outcome measures. All pairwise relationships were significant at p < 0.001. mRS score is strongly correlated to all impairment and function outcomes at the group level.
