Outcome Measures

Primary Outcomes (1)

  • "On" time without troublesome dyskinesia (i.e. Good "On" Time)

    Proportion of aDBS subjects meet a success criterion relative to stable cDBS.The success criterion: no worse than 2 hours/day less of "On" time without troublesome dyskinesia (i.e. Good "On" Time) during aDBS compared to cDBS.

    From the cDBS baseline to aDBS evaulation phase at about 1 month

Other Outcomes (1)

  • Assess the Adverse Event among the Participants

    From enrollment to the end of treatment at around 12 months to 17.5 months

Study Arms (1)

Single-arm who received aDBS "Best" Mode (Dual or Single Threshold )

EXPERIMENTAL
Device: Percept™ PC and Percept RC with Adaptive DBS (aDBS™)

Interventions

Subjects for whom meet the LFP screening criteria and can be acceptably configured on the "Best" aDBS mode (Dual or Single Threshold) will receive "Best" Mode aDBS treatment and enter the aDBS Evaluation Phase.

Also known as: aDBS
Single-arm who received aDBS "Best" Mode (Dual or Single Threshold )

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may not qualify if:

  • General (Assessed at Enrollment Visit):
  • Subject has idiopathic Parkinson's disease
  • Subject is implanted (\>3 months prior to enrollment for new INS implants or \>1 month from INS replacement) with a Percept PC (Model B35200) or Percept RC (Model B35300) and Medtronic DBS leads (Model 3387, 3389, B33005 or B33015) and extensions (Model 37086 or B34000) bilaterally in the same target (physician confirmed), STN or GPi
  • In the opinion of the investigator, the subject responds to DBS Therapy.
  • Based on the opinion of the investigator, the subject's cDBS parameters and PD medications are stable (no changes within the last 4 weeks) and expected to remain stable from enrollment through the end of the aDBS Evaluation Phase
  • Subject is configured to monopolar or dual monopolar stimulation using contacts 1 and/or 2 (9 and/or 10) on at least one side
  • Subject is willing and able to attend all study-required visits and complete the study procedures (e.g. 1-month recall questionnaires, MDS-UPDRS III, Off stim/Off med visit)
  • Subject (or legally authorized representative) has the ability to understand and provide written informed consent for participation in the study prior to the study-related procedures being conducted
  • Subject is a male or non-pregnant female. If female of child-bearing potential, and if sexually active, must be using, or agree to use, a medically-acceptable method of birth control as confirmed by the investigator
  • \. Subject has Alpha - Beta band (8-30 Hz) amplitude ≥ 1.2 μVp detected on either left and/or right DBS leads on sensing channels 0-2, 0-3, 1-3, 8-10, 8-11, or 9-11.
  • General (Assessed at the Enrollment Visit):
  • Subject and/or caregiver is unable to utilize the patient programmer
  • Subject has more than one lead in each hemisphere of the brain
  • Subject has cortical leads or additional unapproved hardware implanted in the brain
  • Subject has more than one INS
  • +11 more criteria
