Abstract

[Purpose] The purpose of this study was to compare H-reflex characteristics during gait of hemiplegic stroke patients. [Subjects] Twenty-five patients and age-matched twenty-five volunteers in good health were studied. All the subjects could walk independently. [Methods] An MP150 (BIOPAC Systems, Inc., Goleta, CA, USA) was used to record the electromyography (EMG) data collected with Ag-Ag/Cl measurement electrodes (BIOPAC, diameter of 2 cm). [Results] The comparison showed significant differences of Hmax/Mmax ratio (%) in all gait cycles between the stroke group and the control group. [Conclusion] In conclusion, this study furnished basic reference data for gait strategies and functional training programs for hemiplegic stroke patients.

摘要

[目的] 本研究旨在比较偏瘫性脑卒中患者步态期间的H反射特征。[对象] 对25例患者和25名年龄匹配的健康志愿者进行了研究。所有受试者均能独立行走。[方法] 使用MP150(美国加利福尼亚州戈利塔市BIOPAC Systems公司)记录通过Ag-Ag/Cl测量电极(BIOPAC,直径2 cm)收集的肌电图(EMG)数据。[结果] 比较显示,卒中组与对照组在所有步态周期中的Hmax/Mmax比率(%)存在显著差异。[结论] 总之,本研究为偏瘫性脑卒中患者的步态策略和功能训练方案提供了基础参考数据。
