The RESTORE Stroke Study combines two phases of study under one protocol (pilot/pivotal). The first phase has a sample size of 40 subjects. The second phase has an estimated sample size of 162 subjects which may be adjusted based on analysis of the first phase.
Each subject will be implanted with the DBS system, undergo DBS program optimization, and be randomized to test treatment (Tt) or active-control treatment (Ct). After randomization, all subjects will participate in a five-month outpatient rehabilitation therapy program. After five months of blinded randomized testing, subjects assigned to active-control treatment (Ct) will cross over to receive test treatment (Tt) and participate in a second five-month therapy program.
