Selective Motor Control is a Clinical Correlate of Brain Motor Tract Impairment in Children with Spastic Bilateral Cerebral Palsy

TBSS results show significant differences (P <.05) in DTI measures between the CP and TDC groups. Coronal slices were selected at the level of the CST. From left to right, axial slices were selected at the level of the motor cortex, PLIC, and CerPed, respectively. Mid-sagittal slices were selected at the level of the CC. A, The WM skeleton is shown in green with arrows labeling the CST, somatosensory cortex, parietal lobe, external capsule, PLIC, anterior limb of the internal capsule (ALIC), and corpus callosum. In the coronal view, ROIs for the SCR (red), PLIC (yellow), CerPed (blue), and sub-CerPed (orange) are shown. Significant differences between the CP and TDC groups are shown for FA (B), RD (C), AD (D), and MD (E). The hot colormaps denote whether a DTI measure for the CP group was less than (red-yellow) or greater than (blue-light blue) that in the TDC group. A indicates anterior; FWE, family-wise error; I, inferior; L, left; P, posterior; R, right; S, superior.
