Reporting Groups
  Description
Sham DBS

Sham stimulation in which no electrical charge is delivered through the Neuropace RNS system.

NeuroPace RNS® System Deep Brain Stimulator: • There will be a one month post-operative period during which stimulation is not turned on.

  • One month post-implant, subjects will be randomized one to one in a blinded fashion to receive active or sham stimulation.
  • By Day 60, all subjects will be programmed to receive active stimulation. Physiological data will be collected for Specific Aim 2 of the study.
  • Both the sham and the active groups (3 subjects in each group) will undergo identical programming procedures at 30 and 60 days.
Active DBS

Active stimulation through the Neuropace RNS system at settings to maximally reduce tic frequency & severity, while limiting potential stimulation-induced side-effects

NeuroPace RNS® System Deep Brain Stimulator: • There will be a one month post-operative period during which stimulation is not turned on.

  • One month post-implant, subjects will be randomized one to one in a blinded fashion to receive active or sham stimulation.
  • By Day 60, all subjects will be programmed to receive active stimulation. Physiological data will be collected for Specific Aim 2 of the study.
  • Both the sham and the active groups (3 subjects in each group) will undergo identical programming procedures at 30 and 60 days.
