White Matter Diffusion Anisotropy and the Effects of Inpatient Multidisciplinary Rehabilitation in Parkinson's Disease: A Diffusion Tensor Imaging Analysis.
BACKGROUND In Parkinson's disease (PD), compensatory increases in corticospinal tract (CST) fractional anisotropy (FA) occur early; whether pretreatment white matter integrity predicts rehabilitation responsiveness is unknown. OBJECTIVE To determine whether pretreatment CST FA predicts inpatient rehabilitation respon...
