Parkinson's Disease (PD)

Brief summary

To compare the efficacy, programming burden, power consumption, and physicians' and patients' satisfaction between current mode and voltage mode of deep brain stimulation in each period one year after surgery.

Detailed description

This is a randomized, parallel controlled, multi-center study to compare the efficacy, programming burden, power consumption, and physicians' and patients' satisfaction between current mode and voltage mode of deep brain stimulation in each period one year after surgery. Participants will be followed for up to 12 months. Approximately 180 PD participants will be recruited from up to 14 sites. Participants will be randomized to current mode or voltage mode after DBS surgery and be comprehensively assessed at baseline and follow up according to the protocol developed.

Interventions

OTHERConstant current (CC) subthalamic nucleus deep brain stimulation

For subjects who have decided to undergo STN-DBS surgery and meet the inclusion criteria, the constant current (CC) mode is selected as the original electronic modality one week after surgery. Regardless of any changes in programming parameters over the following year, the constant current (CC) mode will be maintained.

OTHERConstant voltage (CV) subthalamic nucleus deep brain stimulation

For subjects who have decided to undergo STN-DBS surgery and meet the inclusion criteria, the constant voltage (CV) mode is selected as the original electronic modality one week after surgery. Regardless of any changes in programming parameters over the following year, the constant voltage (CV) mode will be maintained.

Design outcomes

Primary

MeasureTime frameDescription
The change rate of MDS-UPDRS IIIfrom baseline to 6 months after surgeryMDS-UPDRS III is the motor examination section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale), completed by the evaluator, providing an objective assessment of motor symptoms in patients with Parkinson's disease. MDS-UPDRS III ranges from 0-132. The change rate of MDS-UPDRS III in the Stim-On/Med-On state from baseline to 6 months after surgery will be collected. Positive indicates improvement.

Secondary

MeasureTime frameDescription
MDS-UPDRS IIfrom baseline to 6 months after surgeryMDS-UPDRS II is the motor experiences of daily living section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale) and is a self-reported questionnaire completed by the patient. The change rate of MDS-UPDRS II from baseline to 6 months after surgery will be collected.
MDS-UPDRS IVfrom baseline to 6 months after surgeryMDS-UPDRS IV is the motor complications section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale). This section is rated by the evaluator, combining information provided by the patient with the evaluator's clinical observation and judgment to generate a comprehensive score. The change rate of MDS-UPDRS IV from baseline to 6 months after surgery will be collected.
Clinical Global Impression (CGI)from baseline to 6 months after surgeryThe Clinical Global Impression (CGI) is a global assessment scale initially designed by the World Health Organization (WHO) for use in IPSS research to evaluate clinical efficacy. It provides an overall measure of treatment outcomes.
Physician satisfaction feedbackfrom baseline to 6 months after surgeryThe programming physician completes a custom-made questionnaire based on their subjective judgment.
MDS-UPDRS Ifrom baseline to 6 months after surgeryMDS-UPDRS I is the non-motor experiences of daily living section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale). Subsection IA is evaluated by the researcher based on all relevant information provided by the patient or their caregiver regarding certain symptoms. Subsection IB is completed by the patient, with assistance from the caregiver if needed, but it must not be completed by the researcher. The change rate of MDS-UPDRS I from baseline to 6 months after surgery will be collected.
power consumptionfrom baseline to 6 months after surgeryThe total power consumption of the patient's IPG between visits is calculated. During follow-up, device logs are uploaded from the charging equipment to the database. The raw data is then retrieved from the database.
impecencefrom baseline to 6 months after surgeryUse the programming device to measure impedance on all contacts of the IPG.
Adverse effectsfrom baseline to 12 months after surgeryRecord any adverse events and serious adverse events during the study period.
Patient satisfaction feedbackfrom baseline to 6 months after surgeryThe patient completes a custom-made questionnaire based on their subjective judgment.
