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

Figure 3

Follow-up Fugl-Meyer assessment of the hemiplegic lower extremity (FMA-LE). (a) Linear regression between corticospinal tract (CST) injury and follow-up FMA-LE scores. The symbols indicate the same patient clusters as those shown in (b). The regression is not found, even after the exclusion of patients with an initial FMA-LE score of ≥14 (■). (b) Hierarchical clustering between initial and follow-up FMA-LE scores shows three clusters (■, □, and ×). The solid line is the line of identity.
