Parkinson's disease (PD) may involve sudden unintended arrests in gait or failure to initiate gait, known as gait freezing. Deep brain stimulation of the pedunculopontine nucleus (PPN) has been found to be an effective therapy for this phenomenon. In this study, we characterized the connectivity of the PPN freezing of gait (FOG) patients, compared with non-FOG PD and healthy controls using diffusion tensor imaging techniques. Differences in PPN connectivity profiles of the study groups were s...Expand abstract
