Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
To demonstrate that a higher proportion of DBS responders exhibit a RR relative to non-responders, using maximum tolerated voltage settings, at activated electrode contacts used for DBS stimulation in the SANTE study.		Study testing to occur during the long-term follow-up phase of the SANTE trial.

Secondary Outcomes

Measure	Description	Time Frame
For patients without a RR at their activated DBS electrode contacts used in the SANTE study, demonstrate that activating other electrode contacts generates a RR.		Study testing to occur during the long-term follow-up phase of the SANTE trial.
