Inclusion criteria: 1. Aged 18 to 75 years old male or female; 2. signed informed consent form; 3. primary Parkinsons disease based on the diagnostic criteria of the UK Parkinsons Disease Society Brain Bank for primary Parkinsons disease or the Chinese criteria for Parkinsons disease with a disease course of = 5 years; 4. the efficacy of levodopa has significantly decreased, and motor function fluctuates or motor dysfunction is presented, which reduces the quality of life; 5. adequate dosages of the optimal medications (i.e., levodopa) have been received; 6. Parkinsons disease severity is at Hoehn-Yahr Stage 2.5-4 when medications are not being taken; 7. good compliance, i.e., patients and their families are willing to be enrolled in the clinical trial for bilateral neurostimulation implantation, receive follow-up regularly, can accurately complete the subjects diary during wakefulness, and the family, custodian, or caretaker can help the subject; 8. improvement after L-dopa stimulation test is no less than 30%; 9. off period is more than 4 hours per day.

Secondary
| Measure | Time frame |
|---|---|
| change in daily living scores (UPDRS-II) in subjects of both test group and control group under medications at the end of 3, 6 and 12 months after the surgery;change in mental, behavioral and emotional situation scores (UPDRS-I) in subjects of both test group and control group upon under medications at the end of 3,6 and 12 months after the surgery;changes in complication scores (UPDRS-IV) in the subjects of both test and control group under medications at the end of 3, 6, and 12 months after the surgery;changes in 'on' period and “off” recorded in the diaries of subjects in both test and control groups at the end of 3,6, and 12 months after the surgery;changes in motor function scores (UPDRS-III) during the 'on' and 'off' period of the stimulation in subjects of the test group upon withdrawal of medications('off') at the end of 3 months after the surgery;changes in motor function scores (UPDRS-III) during the 'on' and 'off' period of the stimulation in subjects of the test group under medications and upon withdrawal of medications('off') at the end of 12 months after the surgery;evaluation of the surgery;satisfaction of the subjects; | — |
