Abstract
Objectives: This study aimed to investigate the effects of motor imagery (MI), action observation (AO), and action execution (AE) interventions on the autonomic nervous system (ANS) in individuals with chronic stroke.
Methods: This was a single-center, randomized, case-control study. Thirty-six patients were randomly assigned to MI (n = 10), AO (n = 15), and the AE group (n = 11). Heart rate (HR)-based measurements (HR, heart rate variability (HRV)) and blood pressure were evaluated before the practice of each group. In the MI group, participants were instructed to imagine themselves walking at their own comfortable pace for 5 minutes. Meanwhile, in the AO group, participants were shown a video of a person walking for 5 minutes. Finally, in the AE group, participants were instructed to actually walk for 5 minutes. Then, all measurements were taken again.
Results: A statistically significant difference was found in HR and mean RR interval within the AE group (p < 0.05). There was a statistically significant difference in the Root Mean Square of Successive Differences Between Normal Heartbeats (RMSSD) (ms) within the AO group (p < 0.05). There was a significant difference in HR and mean RR intervals (ms) between groups (p < 0.05). According to post-hoc analyses, HR was statistically significantly higher in the AE group compared to the other groups, and the mean RR interval was statistically significantly lower (p < 0.05).
Conclusions: In conclusion, in patients with chronic stroke, AE and AO may affect ANS by increasing sympathetic activation. It is recommended for future studies to evaluate whether patients actually engage in imagery during the MI task.
研究目的本研究旨在探讨运动想象（MI）、动作观察（AO）和动作执行（AE）干预对慢性中风患者自主神经系统（ANS）的影响：这是一项单中心、随机、病例对照研究。36名患者被随机分配到MI组（10人）、AO组（15人）和AE组（11人）。在每组练习前，对基于心率（HR）的测量（心率、心率变异性（HRV））和血压进行评估。在 MI 组，参与者被要求想象自己以自己舒适的速度行走 5 分钟。同时，在 AO 组中，参与者观看一个人行走 5 分钟的视频。最后，在 AE 组，参与者被要求实际行走 5 分钟。然后，再次进行所有测量：结果：在 AE 组中，心率和平均 RR 间期的差异具有统计学意义（P P P P P 结论：AE 组的心率和平均 RR 间期的差异具有统计学意义（P P P P总之，在慢性中风患者中，AE 和 AO 可能会通过增加交感神经激活来影响自律神经系统。建议在今后的研究中评估患者在完成 MI 任务时是否真的进行了想象。
期刊介绍：
Topics in Stroke Rehabilitation is the leading journal devoted to the study and dissemination of interdisciplinary, evidence-based, clinical information related to stroke rehabilitation. The journal’s scope covers physical medicine and rehabilitation, neurology, neurorehabilitation, neural engineering and therapeutics, neuropsychology and cognition, optimization of the rehabilitation system, robotics and biomechanics, pain management, nursing, physical therapy, cardiopulmonary fitness, mobility, occupational therapy, speech pathology and communication. There is a particular focus on stroke recovery, improving rehabilitation outcomes, quality of life, activities of daily living, motor control, family and care givers, and community issues.
The journal reviews and reports clinical practices, clinical trials, state-of-the-art concepts, and new developments in stroke research and patient care. Both primary research papers, reviews of existing literature, and invited editorials, are included. Sharply-focused, single-issue topics, and the latest in clinical research, provide in-depth knowledge.
