Prediction of Motor Recovery & Outcome Post-Stroke

Prediction of motor recovery and outcome post-stroke by cortico-spinal tract integrity

The cortical spinal tract is marked in light blue.

The PCA yielded two factors accounting for 75% of the variability of motor scores across subjects. Tests for the left body loaded on one factor, while tests for the right body loaded on another factor. Therefore the two motor factors provided a continuous measure of motor performance highly correlated with the NIHSS
