Does Measurement of Corticospinal Tract Involvement Add Value to Clinical Behavioral Biomarkers in Predicting Motor Recovery after Stroke?

Figure 2

Follow-up Fugl-Meyer assessment of the hemiplegic upper extremity (FMA-UE). (a) Linear regression between corticospinal tract (CST) injury and follow-up FMA-UE scores. The symbols indicate the same patient clusters as those shown in (b). The solid line is the regression line, and the dashed line is the regression line after the exclusion of patients with an initial FMA-UE score of ≥35 (■). (b) Hierarchical clustering between initial and follow-up FMA-UE scores shows three clusters (■, □, and ×). The solid line is the line of identity.
