Parkinson Disease Clinical Trial
Official title:
Sacral Nerve Stimulation in the Treatment of Gait Disorder in Patients With Parkinson's Disease
Parkinson's disease (PD) is a progressive disease, characterized by dopaminergic neurons degeneration in the substantia nigra. Postural and gait disorders usually occur in advanced PD patients. However, existing drugs and deep brain stimulation (DBS) therapy are not effective enough for these axial symptoms or cannot maintain long-term efficacy, which seriously reduce patients' quality of life. Sacral nerve stimulation(SNS) is a treatment for urinary symptoms in PD. It has been reported that SNS can also improve PD gait disturbance, but the level of evidence currently is low. We assume that SNS may have a similar mechanism to spinal cord stimulation and may be an effective treatment for PD gait disorder. However, there are few studies on the mechanism of SNS treatment. Therefore, we will conduct a large sample, prospective case-control study to provide a higher level of clinical evidence for sacral nerve stimulation in the treatment of gait disturbance in PD. Our primary objective is to evaluate the efficacy of SNS for gait disorder in PD. PD patients who have received DBS surgery but still have severe gait problems will be included. This study will contribute to evaluate the efficacy of SNS for gait disorder in PD, provide level II evidence for expanding the indications of SNS, varicocelectomy., and improve patients' quality of life.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Parameter changes in Timed Up and Go Test | Patients should stand up from the chair, walk forward for 3m with daily speed, turn after passing the marked line, and then walk back to the chair and sit down, leaning back in the chair. Video recordings will be made throughout the test. | Baseline (preoperative), during external test stimulation (1-14 days after electrode implantation), 3 months post-SNS | |
Secondary | Changes in Uni?ed Parkinson's Disease Rating Scale Part ? (UPDRS ?) scores | Uni?ed Parkinson's Disease Rating Scale Part ? (UPDRS ?) measures the motor severity of Parkinson's disease. UPDRS ? score has a range of 0 (no symptoms) to 132 (severe disease symptoms). | Baseline (preoperative), 3 months post-SNS | |
Secondary | Changes in Gait and Fall Questionnaire (GFQ) scores | GFQ is a subjective scale for gait problems in the past 4 weeks. GFQ score has a range of 0 (no gait problems) to 64 (severe gait problems) | Baseline (preoperative), 3 months post-SNS | |
Secondary | Changes in Berg Balance scale (BBS) scores | BBS measures patients' static and dynamic balance abilities. BBS score has a range of 0 (severe balance problems) to 56 (no balance problems). | Baseline (preoperative), 3 months post-SNS | |
Secondary | Changes in 8-item Parkinson's Disease Questionnaire (PDQ-8) scores | PDQ-8 is a reliable and feasible tool for the assessment of quality of life in Parkinson's disease patients. | Baseline (preoperative), 3 months post-SNS | |
Secondary | Changes in EuroQol-5 Dimensions (EQ-5D) scores | EQ-5D measures five dimensions of PD patients' quality of life: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. | Baseline (preoperative), 3 months post-SNS | |
Secondary | Changes in Montreal cognitive assessment (MoCA) scores | The MoCA is a widely used screening assessment for detecting cognitive impairment. MoCA score has a range of 0 (severe dementia) to 30 (cognitive intact). | Baseline (preoperative), 3 months post-SNS | |
Secondary | Changes in Voiding Diary | The voiding diary recording the patient's daily fluid input and urinary output is a simple but effective tool for assessing storage symptoms. | Baseline (preoperative), during external test stimulation (1-14 days after electrode implantation), 3 months post-SNS | |
Secondary | Parameter changes in Dual task | The protocol requires patient to walk along a walkway of 5 m between two retroreflective markers placed 0.5 m. They are asked to make a left or right turn of 360° around the marker before walking further. They are instruted to complete the task with or without a verbal cognitive color classification task. | Baseline (preoperative), 3 months post-SNS | |
Secondary | Parameter changes in Six-Minute Walking Test | This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes. | Baseline (preoperative), 3 months post-SNS | |
Secondary | Parameter changes in Rapid 360° Turn | The test requires patients to make rapid 360° turns on the spot in both directions. | Baseline (preoperative), 3 months post-SNS |
