摘要:

研究已证实,功能训练与WalkAide功能性电刺激可改善脑卒中后患者的功能,但两者联合应用对脑卒中后患者功能的改善作用,以及在这一过程中与脑卒中的病理生理和进展有关的表观遗传标志物和氧化应激的变化尚不清楚。因此,这项交叉设计研究纳入12例年龄54-72岁的脑卒中后患者,给予他们单次45min功能训练,然后经7d的洗脱期后,给予患者相同的45min功能训练,同时给予其WalkAide功能性电刺激干预。联合干预后患者的Berg平衡量表(BBS)得分较干预前明显提高,但Timed Up and Go(TUG)测试评分在干预前后无明显差异。联合干预患者的认知功能较单独功能训练明显改善,外周血SOD水平也更高。外周血组蛋白脱乙酰基酶(HDAC2)和组蛋白乙酰基转移酶(HAT)活性则在接受联合干预与单独功能训练干预的患者间无明显差异。结果说明与传统的康复手段相比,WalkAide功能性电刺激联合单次功能训练在平衡能力和认知能力上更有效,该作用可能与调节氧化应激状态有关。该研究已于2018年3月22日获得循道卫理大学中心IPA的研究伦理委员会批准(批准号2.423.376)。

Abstract: A growing body of evidence has suggested that the imbalance of epigenetic markers and oxidative stress appears to be involved in the pathophysiology and progression of stroke. Thus, strategies that modulate these biomarkers might be considered targets for neuroprotection and novel therapeutic opportunities for these patients. Physical exercise has been reported to induce changes in these epigenetic markers and improve clinical outcomes in different populations. However, little is reported on this in post-stroke patients. The purpose of this study was to investigate the effect of a single exercise session with WalkAide functional electrical stimulation (FES) on cognitive performance, clinical functional parameters, oxidative stress and epigenetic modulation in post-stroke individuals. In this crossover design study, 12 post-stroke individuals aged 54–72 years of either sexes were included and subjected to a single session of exercise (45 minutes) without WalkAide functional electrical stimulation (EXE alone group), followed by another single session of exercise (45 minutes) with WalkAide functional electrical stimulation (EXE + FES group). The clinical functional outcome measures, cognitive performance and blood collections for biomarker measurements were assessed pre- and post-intervention. After intervention, higher Berg Balance Scale scores were obtained in the EXE + FES group than in the EXE alone group. There was no significant difference in the Timed Up and Go test results post-intervention between EXE alone and EXE + FES groups. After intervention, a better cognitive performance was found in both groups compared with before the intervention. After intervention, the Timed Up and Go test scores were higher in the EXE + FES group than in the EXE alone group. In addition, the intervention induced lower levels of lipid peroxidation. After intervention, carbonyl level was lower, superoxide dismutase activity and superoxide dismutase/catalase activity ratio were higher in the EXE + FES group, compared with the EXE group alone. In each group, both histone deacetylase (HDAC2) and histone acetyltransferase activities were increased after intervention compared with before the intervention. These findings suggest that a single exercise session with WalkAide FES is more effective on balance ability and cognitive performance compared with conventional exercise alone in post-stroke patients. This is likely to be related to the regulation of oxidative stress markers. The present study was approved by the Research Ethics Committee of the Methodist University Center-IPA (approval No. 2.423.376) on December 7, 2017 and registered in the Brazilian Registry of Clinical Trials—ReBEC (RBR-9phj2q) on February 11, 2019.
