摘要

本研究旨在确定卒中患者和非卒中患者在双支撑阶段的下肢运动学、动力学、肌肉活动及其变异性方面的差异。11名中风后的参与者和13名健康的参与者在光电运动捕捉系统、两个测力板和肌电图系统的监测下,以自己选择的速度进行了10次步态试验。在双支撑过程中评估以下结果:时间和关节位置;对质心的外部机械功;以及相对肌电活动。在双支撑阶段,分别对卒中和非卒中参与者的对侧/同侧和优势/非优势进行了评估。分析10次试验各参数的平均值和变异系数。卒中后的参与者表现为双侧质量中心的机械功减少,变异性增加,对侧膝关节和踝关节屈曲在后位减少,同侧膝关节屈曲在前位增加,变异性增加。中风后的参与者相对肌肉活动增加,变异性降低。质心的机械功似乎是识别中风后受试者肢间协调障碍的最相关参数。

Interlimb Coordination during Double Support Phase of Gait in People with and without Stroke.

This study aims to identify differences between participants with and without stroke regarding the ipsilesional and contralesional lower limbs kinematics, kinetics, muscle activity and their variability during double support phase of gait. Eleven post-stroke and thirteen healthy participants performed 10 gait trials at a self-selected speed while being monitored by an optoelectronic motion capture system, two force plates and an electromyographic system. The following outcomes were evaluated during the double support: the time and the joint position; the external mechanical work on the centre of mass; and the relative electromyographic activity. Both, contralesional/ipsilesional and dominant/non-dominant of participants with and without stroke, respectively, were evaluated during double support phase of gait in trailing or leading positions. The average value of each parameter and the coefficient of variation of the 10 trials were analysed. Post-stroke participants present bilateral decreased mechanical work on the centre of mass and increased variability, decreased contralesional knee and ankle flexion in trailing position, increased ipsilesional knee flexion in leading position and increased variability. Increased relative muscle activity was observed in post-stroke participants with decreased variability. Mechanical work on the centre of mass seems to be the most relevant parameter to identify interlimb coordination impairments in post-stroke subjects.

期刊介绍: The Journal of Motor Behavior, a multidisciplinary journal of movement neuroscience, publishes articles that contribute to a basic understanding of motor control. Articles from different disciplinary perspectives and levels of analysis are encouraged, including neurophysiological, biomechanical, electrophysiological, psychological, mathematical and physical, and clinical approaches. Applied studies are acceptable only to the extent that they provide a significant contribution to a basic issue in motor control. Of special interest to the journal are those articles that attempt to bridge insights from different disciplinary perspectives to infer processes underlying motor control. Those approaches may embrace postural, locomotive, and manipulative aspects of motor functions, as well as coordination of speech articulators and eye movements. Articles dealing with analytical techniques and mathematical modeling are welcome.
