Population Size and Eligible Patients: The study will enroll patients with Parkinson's disease (n=30) who had an IPG replacement from Activa PC (older generation of neurostimulator) to Medtronic PerceptTM PC (newer generation of neurostimulator) as a part of their standard-of-care. No patient will be receiving the system for research purposes only.
Study Design: This is a prospective, double-blinded, randomized, cross-over clinical investigation to further investigate the efficiency of Medtronic PerceptTM PC neurostimulator. This study involves three in clinic visits. During the first study visit, the patients' neurostimulator will be reprogrammed using all the additional features the Percept PC has to offer. At the end of the visit, the patients will be randomized between their baseline program, ((Activa PC group) and the newly defined programming settings (Percept Group). During the second visit (1-month follow-up) the effect will be clinically assessed, and a crossover of the condition will happen. The third visit (2-month follow-up) will be a follow-up visit with no programming but only clinical assessment.
Study Duration: Expected study duration is 1 year with the possibility for renewals.
Objectives and outcome measures: The goal is the study is to define whether or what the benefit is of the Percept PC neurostimulator compared to the older Activa PC neurostimulator. The primary outcome is patient-reported global impression of change (PGIC). The secondary outcome measures are clinical scales assessing symptoms of Parkinson's disease (UPDRS-III and -IV) and quality of life (PDQ-39), the active problems list and amount of medication intake.

| Programming DBS using Percept PC neurostimulator's full potential | Other | This study aims to enroll patients who previously had Activa PC neurostimulator and underwent a battery change to Medtronic PerceptTM PC as standard-of-care. However, in this study, the investigators intent to fully utilize the programming potential of Medtronic PerceptTM PC to optimize treatment outcome. |
| Measure | Description | Time Frame |
|---|---|---|
| Patients' Global Impression of Change (PGIC) scale | the investigators expect to see an improvement of PGIC due to a decrease in (the severity of) active problems. The PGIC scale ranges from 1 to 7, with 1 indicating no change and 7 signifying a substantial improvement. | First programming (Baseline) - Crossover programming (1 month Follow-up)- Third month Follow-up |
| Measure | Description | Time Frame |
|---|---|---|
| MDS-UPDRS-III | the investigators expect to see an improvement in the MDS-UPDRS-III. Part III: Motor examination: 0 to 132, with higher scores indicating greater motor impairment. | First programming (Baseline) - Crossover programming (1 month Follow-up)- Third month Follow-up |
| MDS-UPDRS-IV |
