Effects of brain-computer interface technology on balance function and serum IL-6 and TNF-α levels in ischemic stroke patients
目的 观察脑机接口控制脚踏训练系统对缺血性脑卒中患者平衡功能及血清白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)水平的影响.方法 选择2022年9月—2023年9月住院治疗的40例缺血性脑卒中患者作为观察对象.根据随机数字表法将患者均分为卒中对照组和卒中实验组.同时招募20例性别、年龄相当的健康受试者作为健康对照组,采集相关足底压力数据.卒中对照组患者接受包括上下肢主被动运动训练系统在内的常规康复训练,卒中实验组将卒中对照组中的上下肢主被动运动训练系统替换为脑机接口控制脚踏训练系统进行康复治疗,其他不变.治疗4周前后使用足底压力评估系统分别采集两组卒中患者睁闭眼状态下的双侧足底压力对称指数(SI)及身体压力中心(COP)摆动面积;采用Fugl-Meyer下肢运动功能评分(FMA-LE)、Berg平衡量表(BBS)对两组卒中患者进行评估;同时比较两组治疗前后血清IL-6、TNF-α水平.结果 ①两组卒中患者治疗后睁闭眼状态下的SI值及COP摆动面积均较入院前改善,且卒中实验组结果优于卒中对照组(P＜0.05),但与健康对照组仍存在差距(P＜0.05).②两组卒中患者治疗后BBS、FMA-LE评分均较治疗前升高,且卒中实验组分数大于卒中对照组,差异有统计学意义(均P＜0.05).③两组卒中患者治疗后血清IL-6、TNF-α水平均较前下降,卒中实验组血清IL-6、TNF-α水平下降程度大于卒中对照组,差异有统计学意义(P＜0.001,P＜0.05).结论 脑机接口控制脚踏训练系统对于缺血性脑卒中偏瘫患者平衡功能的恢复具有促进作用,其机制可能与血清IL-6、TNF-α水平降低有关.
Objective To observe the effects of brain-computer interface-controlled pedal training system on bal-ance function and serum interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)levels in ischemic stroke pa-tients.Methods Forty patients with ischemic stroke who were hospitalized from September 2022 to September 2023 were selected as observation subjects.The patients were equally divided into stroke control group and stroke experimental group according to the random number table method.At the same time,20 healthy subjects with similar gender and age were recruited as the healthy control group to collect relevant plantar pressure data.Patients in the stroke control group received conventional rehabilitation training including the upper and lower extremity active and passive motor training system,and the stroke experimental group replaced the upper and lower extremity active and passive motor training system in the stroke control group with the brain-computer interface-controlled pedal training system for rehabilitation treatment,and other things remained unchanged.Bilateral plantar pressure symmetry index(SI)and center of body pressure(COP)swing area were collected from both groups of stroke patients with eyes open and closed using the plantar pressure assessment system before and after 4 weeks of treatment.Fugl-meyer low-er extremity motor function score(FMA-LE)and berg balance scale(BBS)were used to evaluate the two groups of stroke patients.Serum IL-6 and TNF-α levels were also compared between the two groups before and after treat-ment.Results ① The SI value and COP swing area in the eyes open and closed state improved in both groups of stroke patients after treatment compared with that before admission,and the results of the stroke experimental group were better than those of the stroke control group(P＜0.05),but there was still a gap with the healthy control group(P＜0.05).②The BBS and FMA-LE scores of stroke patients in both groups were higher after treatment than before treatment,and the scores of the stroke experimental group were greater than those of the stroke control group,with statistically significant differences(all P＜0.05).③Serum IL-6 and TNF-α levels decreased in both groups of stroke patients after treatment compared with before,and the degree of decrease in serum IL-6 and TNF-αlevels in the stroke experimental group was greater than that in the stroke control group,and the difference was sta-tistically significant(P＜0.001,P＜0.05).Conclusion Brain-computer interface-controlled pedal training sys-tem has a facilitating effect on the recovery of balance function in hemiplegic patients with ischemic stroke,and its mechanism may be related to the reduction of serum IL-6 and TNF-α levels.
