摘要

目的/背景本研究探讨了节律性听觉刺激(RAS)对脑卒中偏瘫患者手臂伸展过程中肌肉活动和肘部运动的影响。方法在本研究中招募了16名居住在社区的成年中风患者。RAS由数字节拍器发出的声音组成。当参与者笔直地坐在椅子上时,无论是否有RAS,他们都将手臂伸向目标(桌子上的开关)。在到达过程中使用三维运动分析系统和体表肌电图系统进行测量。结果在伸展动作中,有RAS的动作比无RAS的动作表现更好。RAS缩短了运动时间(p = 0.002),减小了加速度变化(p = 0.001),增加了肘部伸展的运动范围(p = 0.001),增加了肱三头肌的肌肉激活(p = 0.024),降低了患臂的共收缩比(p = 0.015)。结论ras可能是一种促进脑卒中患者患臂运动功能改善的有效技术。

Effects of Rhythmic Auditory Stimulation During Hemiplegic Arm Reaching in Individuals with Stroke: An Exploratory Study

Objective/Background

This study investigated the effects of rhythmic auditory stimulation (RAS) on muscle activity and elbow motion during arm reaching with hemiplegic arm in participants with stroke.

Methods

Sixteen adults with stroke who resided in a community were recruited in this study. The RAS consisted of sound emitted from a digital metronome. While sitting upright in a chair, participants reached their arms towards a target (a switch on a table) both with and without RAS. The three-dimensional motion analysis system and surface electromyography system were used for measurements during the reaching tasks.

Results

We found that RAS elicited better performance in reaching movements than those movements performed without RAS. RAS shortened the movement time (p = .002), reduced the change in acceleration (p = .001), increased the elbow extension range of motion (p = .001), increased muscle activation of the triceps brachii (p = .024), and reduced the co-contraction ratio (p = .015) of the affected arm.

Conclusion

RAS might be a useful technique to facilitate improvements in motor function of the affected arm in patients with stroke.

期刊介绍: The Hong Kong Journal of Occupational Therapy is the official peer-reviewed open access publication of the Hong Kong Occupational Therapy Association. The Journal aims to promote the development of theory and practice in occupational therapy (OT), and facilitate documentation and communication among educators, researchers and practitioners. It also works to advance availability, use, support and excellence of OT and maintain professional standards to promote better understanding of OT.
