Eligibility
Inclusion criteria
Inclusion criteria: Age ≥ 18 years bilaterally implanted with the Boston Scientific® Vercise™ system in the STN for idiopathic Parkinson’s Disease at least 6 months previous to study enrollment the optimal ring-mode stimulation setting has been found for the patient: changing settings will either (a) not improve the motor scores or (b) cause stimulation-induced side-effects Patients who have received this system by participating in the GALAXY-trial can only be randomized after completion of the GALAXY trial.
Exclusion criteria
Exclusion criteria: no adequate stimulation response in ring-mode on one of the steerable levels (second and third contact point on each lead) Legally incompetent adults Active psychosis No written informed consent
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will evaluate the difference of motor symptoms in patients with steered and ring-mode DBS in standardized OFF-drug phase measured with the Movement Disorders Society Unified Parkinson Disease Rating Scale motor evaluation (MDS-UPDRS-ME). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome consists of symptom scales, used stimulation settings, medication use, stimulation-induced side-effects, activities of daily living scales and a quality of life questionnaire. At the end of the trial, patients will be asked to choose between the two used programs to evaluate which one was perceived as the best. A sub-analysis will be performed to evaluate whether good DBS responders and suboptimal DBS responders score differently on primary and secondary endpoints. | — |
