Further study details as provided by MedtronicNeuro:

Primary Outcome Measures:
  • To Characterize the Percentage of Leads in Which the Target Map and the Clinically-derived Activation Map Overlap [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    The one-sided 95% exact binomial lower confidence bound of the proportion was calculated from subjects with readable images enrolled in the study.

Secondary Outcome Measures:
  • Additional Study Measure on Unified Parkinson's Disease Rating Scale (UPDRS) III Scores [ Time Frame: Change from baseline to 18 months ] [ Designated as safety issue: No ]
    The summary of UPDRS III medication off score at baseline and the UPDRS III stimulation on/medication off score at follow-up and the change from baseline to 18 months. The UPRS III has a range of 0 - 108.

Enrollment: 20

Groups/Cohorts Assigned Interventions
Parkinson's disease Subjects
Subjects with advanced Parkinson's Disease implanted with Medtronic DBS system in the subthalamic nucleus (STN).
Device: Medtronic DBS system
Advanced Parkinson's disease patients implanted with the Medtronic Deep Brain Stimulation (DBS) system.

Detailed Description:

This is a study done on Parkinson disease subjects who have received the DBS system implanted in their subthalamic nucleus.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Parkinson's disease patients who have been implanted with the DBS system


Inclusion Criteria:

  • Patient with Medtronic Deep Brain Stimulation therapy for idiopathic levodopa responsive Parkinson's Disease
  • Patient who has had lead placement in the Subthalamic nucleus
  • Patient with pre-op MRI available
  • Patient with post-op CT scan available showing placement of the lead
  • Patient who has documented improvement of at least 35% on UPDRS III scores from baseline preoperative off medication state compared to post DBS implant stimulation on/medications off

Exclusion Criteria:

  • Patient who has had clinically significant persistent stimulation related adverse effects
  • Patient who has evidence of lead migration without lead revision
  • Patient with other brain malformations that would make it difficult to process images (ablative surgery in the basal ganglia, resective surgery, brain tumor)
