Abstract
Gait disorders are major problems among patients with cerebellar ataxia (CA) and Parkinson’s disease (PD). Little is known on how damages to the cerebellum or the basal ganglia affect the recovery responses to external gait perturbations. Six patients with CA, six patients with PD and six healthy controls (HC) were exposed to 9 blocks of 8 antero-posterior (AP) and medio-lateral (ML) perturbations. AP and ML Base of support (BoS) were compared between groups at perturbation onset and the following five heel strikes. HCs showed longer AP BoS than the CA and PD groups. Patients with CA showed a wider ML BoS than the HC and PD groups. Patients with PD were unable to take longer or larger steps when necessary (i.e., in reaction to anterior and medial perturbations). These findings could help to design specific perturbation-based training in patients with different degenerative neurological diseases.
