While gait disorders may arise from many different etiologies, dysfunction of the cerebellum (a part of the brain with the function of coordination of movement) leading to gait disorders results in distinct features. Gait ataxia is a specific type of neurological gait disorder and is defined as the presence of abnormal, uncoordinated movements associated with gait. To date, there are limited treatments for ataxia and\u002For gait disorders. Deep brain stimulation (DBS) is a neurosurgical tool that has been widely used for over twenty years, mainly to treat Parkinson's disease, dystonia, and essential tremor. In this study, we aim to implant DBS in patients with ataxia and\u002For gait disorder in the cerebellum area, and electrically stimulate them in a titratable and ultimately reversible manner. This study is divided into 3 phases: pre-operative, operative and post-operative phase. The purpose of this pilot study is to evaluate the safety, feasibility, and to validate the DBS of cerebellar cortical and deep nuclei in patients with treatment refractory ataxia.
