Stroke Clinical Trial
Official title:
Comparative Study of the Efficacy and Safety of Deep Brain Stimulation Versus Vagal Stimulation for Post-stroke Hemiplegia: Study Protocol for a Multicenter Randomized Controlled Trial
Background: Hemiplegia is a common complication after a stroke. Studies have shown that traditional medical and rehabilitation treatments are not good for improving patients' motor function, deep brain stimulation (DBS) and vagus nerve stimulation (VNS) can improve the motor function of patients, but there is no comparative study between them. Objectives: This study compares the efficacy and safety of DBS and VNS in the recovery of motor function in patients with post-stroke hemiplegia, determining the best treatment for patients with post-stroke hemiplegia, and providing high-level clinical evidence for patients and clinicians to choose from. Methods/Design: This is a randomized, double-blind, sham-controlled, cross-controlled pilot study. A total of 98 patients with post-stroke hemiplegia are assigned to receive DBS or VNS. After 3 and 6 months of follow-up, all the devices are turned off. After a 2-week washout, the control group is turned on, but the stimulation group is given sham stimulation. After 9 and 12 months of follow-up, all the devices are turned on. Then, at postoperative 15 and 18 months, postoperative neuroimaging and various post-stroke motor-related scores were performed for data collection and analysis. Discussion: We propose a study design and rationale to compare the efficacy and safety of DBS and VNS in patients with post-stroke hemiplegia to provide evidence and reference for implantable neuromodulation in the treatment of post-stroke dysfunction, and to compare the therapeutic effects of DBS and VNS to provide evidence for patient and clinical diagnosis and treatment choices. Study limitations are related to the small sample size and short study period.

Primary | Motor function intervention effect: Fugl-Meyer Assessment Scale (FMA) | Fugl-Meyer Assessment Scale (FMA) was used to measure the motor function of stroke patients. FMA is widely used in clinical motor function assessment and is a quantitative stroke-specific scale used to assess motor function, balance, sensory and joint function in hemiplegic patients. Each of the five domains contains different assessment items, which are scored on a 3-point scale: 0 = unable to perform. 1 = Partially performed, 2 = Fully performed This scale has been found to have good validity and reliability in the stroke population . There are 17 items in total, and the higher the score, the better the motor function. | Up to 1.5 year postoperatively | |
Secondary | Overall improvement of clinical symptoms | The NIHSS score is used to evaluate the degree of neurological deficit in stroke patients. The baseline evaluation can assess the severity of stroke, and the treatment effect can be regularly evaluated after treatment. Scores range from 0 to 42, with higher scores indicating more severe neurological damage. ; Patients with a score of 16 are likely to die; A score of 6 is highly likely to have a good recovery. | Up to 1.5 year postoperatively | |
Secondary | The incidence of surgical complications and side effects | Continuously record the subjects' complications and side effects | Up to 1.5 year postoperatively | |
Secondary | Change of 36-item Short Form General Health Survey (SF-36) | The SF-36 scale is a comprehensive index that reflects the health status of individuals.This scale has 8 dimensions to evaluate health-related quality of life, namely, physical function (PF), role physical (RP), body pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), mental health (MH). Higher score indicates better health status. | Up to 1.5 year postoperatively | |
Secondary | Change of Hamilton Anxiety Scale (HAMA) | HAMA score can better reflect the severity of anxiety. It is composed of two parts, namely, physical anxiety (item 7-13) and mental anxiety (item 1-6, 14). Total score = 29 points: severe anxiety; Total score =21 points: there must be significant anxiety; Total score =14 points: there must be anxiety; Total score = 7 points: you may have anxiety; Total score < 7 points: there are no symptoms of anxiety. | Time Frame: Six months postoperatively, and one year postoperatively. | |
Secondary | Change of 24-item Hamilton Depression Scale (HAMD) | HAMD score can better reflect the severity of depression. Total score < 7 points: normal; Total score 7-17 points: possible depression; Total score 17-24 points: definitely depression; Total score > 24 points: severe depression. | Up to 1.5 year postoperatively |
