Postural instability/gait disorder (PIGD) is one of the motor symptoms of Parkinson's disease, which affects the quality of life of patients with Parkinson's disease. At present, deep brain stimulation（DBS）can significantly improve tremor and bradykinesia, but whether deep brain stimulation is effective for gait disorders is still a controversial topic. In addition, the previous gait assessment mainly focused on scales or simple walking tests, and appropriate and effective evaluation methods are needed to evaluate the efficacy of intervention for gait disorders in PD patients. Therefore, in view of these problems, this study will use wearable devices and traditional scale evaluation to explore the effects of deep brain stimulation on gait in patients with Parkinson's disease.\n\nMethods: A total of 30 patients with Subthalamic nucleus DBS（STN-DBS）were expected to be enrolled. By adjusting the parameters of STN-DBS (voltage, frequency, pulse width), the effects of different parameters on PD gait were compared. Gait changes were mainly analyzed by wearable devices and MDS Unified Parkinson's Disease Rating Scale assessment（MDS-UPDRS）. The （Timed Up and Go）TUG test, narrow channel task, circle task and trajectory analysis were performed in the unmedicated state. The wearable device was used to collect the motion information of 10 different positions of the human body, including the wrist, thigh, ankle, foot tip, chest and waist nodes. (1)Experiment 1: Patients were divided into pre-operation group and post-operation group. A case-control study was conducted, and patients were followed up at 1 month,3 months,6 months and 1 year after operation. (2)Experiment 2: This study was a single-center, randomized, double-blind, crossover trial of deep brain stimulation with a short pulse width (30s) versus conventional pulse width (60 s) in PD patients with bilateral STN-DBS. Gait data and MDS-UPDRS were collected at baseline, after 4 weeks and 8 weeks. (3)Experiment 3: By adjusting the frequency parameters of STN-DBS (30,100, and 130HZ), gait data and MDS-UPDRS were collected after 10 minutes of the washout period, and the best DBS parameters for gait improvement were maintained for 4-8 weeks and then evaluated again.\n\nExpected results: By adjusting the parameters (voltage, frequency, and pulse width) of STN-DBS, the potential mechanisms for improving gait disorders in PD were explored, meaningful digital biomarkers for PD gait prognosis were explored, and long-term programming of STN-DBS was guided."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '40 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* (1) Age 40-75 years old; (2) Patients who meet the Chinese Parkinson's disease diagnostic criteria and confirmed by two high-level physicians (\\>10 years); (3) Diagnosed by Parkinson's Specialty Clinic For Parkinson's disease for more than 1 year and have been effective after treatment; (4) Hearing, visual and cognitive abilities are normal; (5) The subjects were informed of the test purpose, the benefits of the test, the test process and possible unexpected situations before the test , and signed the trial informed consent form.\n\nExclusion Criteria:\n\n* (1) A variety of secondary Parkinson's syndrome (including traumatic, drug-induced, tumor, vascular, toxic, hydrocephalus, etc.) and Parkinson's superimposed syndrome.
