This part of the study will collect information on safety and potential efficacy endpoints as assessed by experienced neurologists. The "short term follow-up" phase will be considered complete when the endpoint assessment has been performed for all patients.\n\nPatients, who will not experience severe side effects and who will be deemed suitable by the neurologist, will be eligible to continue in the "long-term follow-up" phase (i.e. 1 month) in their "home" environment. The "AlphaDBS" System will deliver the stimulation in aDBS or cDBS mode, for two weeks in each mode.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': False, 'eligibilityCriteria': "IPG Replacement Patients:\n\nInclusion Criteria\n\n1.
