Abstract: Background: The leftover movement disorder of stroke patients is one of the main causes of disability, and there is still no specific solution. Studies have shown that the improvement of movement disorder symptoms in patients receiving DBS is a potential therapy. treatment approach. However, at present, there are few large-sample studies in this area at home and abroad, which cannot well reveal its actual therapeutic effect and safety, and do not fully understand its potential neural mechanisms, so it is impossible to form a unified and standardized treatment standard, which limits its wide application in clinical practice. Objectives: This study aimed to determine the efficacy and safety of hemiplegia recovery after deep brain electrical stimulation in stroke patients with hemiplegia. Methods/Design: This was a double-blind randomized cross-over controlled pilot study in which 62 patients were assigned to receive deep brain stimulation (DBS) and randomized into DBS and control groups using a randomized controlled study approach, DBS group One month after the operation, electrical stimulation was started, and the control group was given sham stimulation treatment. After 3 and 6 months of follow-up, all the machines were turned off. After a 2-week washout period, the control group was turned on, but the DBS group was given sham stimulation. After the 9th and 12th month of follow-up, all patients were given start-up treatment, and neuroimaging and various post-stroke motor-related scores were performed for data collection and analysis. Discussion: The investigators propose a research design and rationale to explore the effectiveness and safety of DBS in patients with post-stroke hemiplegia, and provide evidence and reference for DBS in the treatment of post-stroke dyskinesia. Study limitations are related to the small sample size and short study time period.
