摘要

本研究旨在评估动作观察对慢性中风患者行走能力和脑振荡活动的影响。14名慢性中风患者被随机分配到动作观察组(AO)和假观察组(SO)。两组均接受 12 次干预。每个疗程包括 12 分钟的观察训练(实验组的训练内容为运动,假观察组的训练内容为自然图片)和 40 分钟的职业治疗(两组的治疗内容相同)。干预前后,步行能力由运动分析系统进行评估,大脑活动由定量脑电图(QEEG)进行监测。阿尔法频率的大脑不对称性、站立阶段的百分比和步长在 AO 组均有显著变化。只有全局阿尔法功率的变化与 AO 组干预后的速度变化有显著相关性。尽管AO组患者在行走和大脑活动方面有更多改善,但我们的研究未能显示大脑活动变化与干预后功能改善之间存在显著相关性,这可能主要是由于我们的研究样本量较小。试验注册:IRCT20181014041333N1.

Quantitative EEG for the Monitoring of Walking Recovery in Chronic Stroke Patients Receiving Action Observation Training.

The current study aimed to evaluate the effects of action observation on the walking ability and oscillatory brain activity of chronic stroke patients. Fourteen chronic stroke patients were allocated randomly to the action observation (AO) or sham observation (SO) groups. Both groups received 12 sessions of intervention. Each session composed of 12 min of observational training, which depicted exercises for the experimental group but nature pictures for the sham group and 40 min of occupational therapy, which was the same for the both groups. Walking ability was assessed by a motion analysis system and brain activity was monitored using quantitative electroencephalography (QEEG) before and after the intervention. Brain asymmetry at alpha frequency, the percentage of stance phase, and step length showed significant changes in the AO group. Only the change in global alpha power was significantly correlated with the change in velocity after the intervention in AO group. Despite more improvements in walking and brain activity of patients in the AO group, our study failed to show significant correlations between the brain activity changes and functional improvements after the intervention, which might be mainly due to the small sample size in our study. Trial registration: IRCT20181014041333N1.

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.
