Abstract

Introduction and Objective. Surface electromyography (sEMG) measurements are a valid method for sublesional muscle activity following spinal cord injury (SCI). In the literature there are few reports evaluating the effect of robotic assisted gait training (RAGT) on the sEMG properties change in SCI patients. The aim of this study was to evaluate the influence of RAGT on observed change of sEMG, and in 64 incomplete SCI patients in the sub-acute stage in relation to functional scales. Materials and Method. In the presented single-centre single arm, single-blinded study, the patients were divided into two groups: experimental group with RAGT (exoskeleton EKSO-GT or Locomat-Pro) and the control group with dynamic parapodium training (DPT). The therapy was conducted in two cycles of three weeks for six days a week, with a seven day break between cycles. Obtained measurements were averaged peak muscle amplitude (AMA) in sEMG and maximal torque (MT) on Luna apparatus (muscle strength testing) and functional scales. Results. Statistically significant differences between S0 and S1 were only observed for the change in MT values at the knee joint during extension, and positively correlated with American Spinal Injury Association Impairment Scale, lower limb motor score, and functional scales. A statistically increased value of the Walking Index for Spinal Cord Injury (WISCI-II) and motor score after rehabilitation relative to the initial value, was seen after RAGT in comparison to patients with DPT, but AMA did not differ between patients. Conclusions. sEMG did not provide sufficient information about SCI outcome after RAGT rehabilitation.
脊髓损伤患者在急性期后康复阶段接受机器人辅助步态训练后的表面肌电图与临床结果比较
导言和目的。表面肌电图(sEMG)测量是了解脊髓损伤(SCI)后局部肌肉活动的有效方法。文献中很少有报告评估机器人辅助步态训练(RAGT)对 SCI 患者 sEMG 特性变化的影响。本研究旨在评估机器人辅助步态训练对观察到的 sEMG 变化的影响,以及对 64 名处于亚急性阶段的不完全脊髓损伤患者的功能量表的影响。材料和方法。在这项单中心、单臂、单盲研究中,患者被分为两组:实验组使用 RAGT(外骨骼 EKSO-GT 或 Locomat-Pro),对照组使用动态副平台训练(DPT)。治疗以三个星期为两个周期,每周六天,周期之间休息七天。测量结果为 sEMG 的平均峰值肌肉振幅(AMA)、Luna 仪器(肌力测试)的最大扭矩(MT)以及功能量表。结果。仅在伸展时膝关节处的 MT 值变化方面,S0 和 S1 之间存在统计学意义上的明显差异,且与美国脊柱损伤协会损伤量表、下肢运动评分和功能量表呈正相关。与 DPT 患者相比,RAGT 患者康复后的脊髓损伤步行指数(WISCI-II)和运动评分与初始值相比在统计学上有所增加,但 AMA 在不同患者之间没有差异。结论:SEMG 无法提供有关 RAGT 康复后 SCI 结果的足够信息。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
