Change of the anterior corticospinal tract on the normal side of the brain in chronic stroke patients: Diffusion tensor imaging study

Abstract

We investigated change of the anterior corticospinal tract (CST) on the normal side of the brain in stroke patients, using diffusion tensor tractography (DTT). We recruited 32 stroke patients and 24 control subjects. Motricity Index and DTT for the whole and anterior CSTs were evaluated. According to findings, the fiber number of the anterior CST on the normal side of the brain of stroke patients was related to poor motor function of the affected extremities.
