Brief Summary
Closed-loop DBS is an emerging neuromodulation pattern in Parkinson's disease with dyanmic adjustment of stimulation parameters to patients' disease fluctuations and state of activity. The purpose of this study is to verify the long-term safety and effectiveness of closed-loop DBS. Through comparing with open-loop DBS, the study also determine whether closed-loop DBS is more effective than conventional open-loop DBS on PD treatment.

Outcome Measures
Primary Outcomes (3)
Movement disorders evaluation
Using MDS-UPDRS III rating scale (0-132, the higher score means a worse outcome) and Rush dyskinesia rating scale (0-12, the higher score means a worse outcome) combined with IMU to evaluate the motor function improvement under both closed-loop DBS and open-loop DBS condition
1-3 days
Sleep Structure Evaluation
Using polysomnography evaluation (sleep efficiency,N1/N2/N3/REM/Wake after sleep onset duration and percentage,arousal index) and subjuective sleep quality rating scale to evaluate the sleep improvement under both closed-loop DBS and open-loop DBS condition
1-3 nights
Diary Outcomes in Parkinson's Disease
Using SCOPA-DC (0-87, the higher score means a worse outcome) to evaluate the diary outcomes under both closed-loop DBS and open-loop DBS condition
1-3days
Secondary Outcomes (2)

Other Outcomes (2)
Neurophysiological changes of STN-LFP in daytime and sleep
at 3,6,9,12,15 months compared to baseline
Functional connectivity changes during long-term DBS modulation
at 3,6,9,12,15 months compared to baseline
Study Arms (1)
Bilateral STN DBS Modulation
EXPERIMENTALParticipants will be implanted with bilateral STN DBS using PINS 106RS system. DBS stimulation will be initiated one month post surgery. Follow-up visits will be conducted 1/3/6/9/12/15 months post surgery with clinical evaluation, STN LFP recording and resting state functional MRI testing. During the 6-15 month's visit, short-term closed-loop DBS modulation (from 24hours to 72hours ) will be conducted to test the safety and efficacy of closed-loop DBS therapy.
Interventions
Continuous closed-loop modulation for 24 hours
Continuous open-loop modulation for 24 hours
Continuous closed-loop modulation for 72 hours
Continuous open-loop modulation for 72 hours
Eligibility Criteria
You may qualify if:
- Diagnosis of primary Parkinson's disease: Diagnosis of primary Parkinson's disease should meet the diagnostic criteria outlined in the "Diagnosis Standards for Parkinson's Disease in China" published in 2016 or the diagnostic criteria for primary Parkinson's disease by the International Parkinson and Movement Disorder Society (MDS) published in 2015.
- Good response to levodopa combination therapy.
- Significant reduction in drug efficacy or significant impact on the patient's quality of life due to prominent motor complications.
- Intolerable adverse reactions to medication affecting its efficacy.
- Presence of uncontrollable tremors despite medication.
You may not qualify if:
- Patients who have undergone pallidotomy or other brain surgeries.
- Patients with secondary Parkinson syndromes or Parkinson plus syndromes.
- Patients with concurrent central nervous system and peripheral nervous system diseases.
- Patients with severe systemic diseases, unstable vital signs, or those who cannot tolerate clinical assessments.
- Patients with severe psychiatric disorders.
- Patients who are unable to provide informed consent due to cognitive or communication impairments or those who refuse to sign the informed consent form.
