Detailed Description

The investigators will conduct a prospective study in patients with Parkinson's disease (PD) implanted with standard of care, subthalamic nucleus (STN) deep brain stimulation (DBS) electrodes, to test whether monopolar sensing of the maximal power in the beta frequency range (in STN) predicts the optimal therapeutic stimulation setting for alleviation of PD motor symptoms. Participants in this study will have been implanted with a Medtronic DBS system consisting of a PerceptTM PC neurostimulator (battery) and SenSight™ DBS leads (implanted electrodes) with BrainSenseTM technology. The DBS surgery is a standard of care procedure, and no alteration of the surgical plan will occur for research purposes . The ranked response between the clinical profile (therapeutic benefit and adverse effects) and beta power will be compared for all electrical contacts on the implanted electrode. Additional analysis of monopolar sensing compared to differential bipolar sensing, location/distance and volume of neural activation (VNA) of optimal contacts identified by beta power or therapeutic window will be estimated with respect to the STN.

Aim 1- Determine whether monopolar sensing of beta power, in the outpatient clinic setting, will predict the optimal therapeutic contact for electrical stimulation of the STN.

Aim 2 - Long Term Follow Up (>12 months) of the same consented study participants to determine the stability of the beta power to determine the optimal contact for therapeutic stimulation.

Study Population

PD patients undergoing implantation of Medtronic DBS system; Sensight(TM) lead and Percept (TM) battery

Description

Inclusion Criteria: Parkinson's Disease, scheduled to undergo bilateral subthalamic nucleus (STN) Deep Brain Stimulation (DBS) surgery at the University of Colorado Hospital, chosen to have a Medtronic Deep Brain Stimulation system implanted (Percept™ battery & SenSight™ electrode). Parkinson's Disease causes upper extremity bradykinesia (slowness of movement) with a MDS-UPDRS1score of 2 or higher when you are off your PD medications.

-

Exclusion Criteria: Dementia or other psychological disorders that precludes consent to participate. Inability to follow testing procedures as determined by the study doctor. Inability to be OFF medication for study visits. Existing implanted Deep Brain Stimulation system or implanted cardiac device. Unilateral Medtronic DBS system, or programming not occurring at the University of Colorado Hospital.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To compare beta frequency power to the TW of each contact.
Time Frame: 2 study visits of 4 hours each, one week apart.
Contacts will be ranked from highest to lowest in beta frequency power and compared to the rankings of the TW from largest to least. It is hypothesized that there will NOT be a statistically significant difference between the ranks for beta power and TW. This would indicate that the contact with the highest beta frequency power also had the largest TW and the converse also being evident.
2 study visits of 4 hours each, one week apart.
