Safety and Efficacy of Adaptive DBS Vs Conventional DBS in Patients With Parkinson's Disease

This is an exploratory study to preliminary assess safety and efficacy of an adaptive Deep Brain Stimulation (DBS) closed-loop method in patients with PD. The study has been designed as a double blind randomized crossover trial that uses conventional DBS as a concurrent control in PD patients in need of Implantable Pulse Generator (IPG) replacement.

PD patients in need of IPG replacement will be screened to identify the ones eligible for enrollment. Randomized patients will undergo 2 days of experimental sessions (i.e. one per each type of stimulation mode, cDBS and aDBS), in a well-controlled environment (i.e. during hospitalization). During each experimental session experienced neurologists will collect information on safety and efficacy endpoints.
