Abstract

Purpose: The purpose of this study was to quantify ipsilesional upper extremity (UE) stand-reaching performance (kinematics and kinetics) among chronic stroke survivors.

Method: Community-dwelling chronic stroke survivors (n=13) and age-similar healthy adults (n=13) performed flexion- and abduction-reaching tasks. Surface EMG and acceleration were sampled using wireless sensors from the prime movers (anterior and middle deltoid) and provided performance-outcome (reaction time, burst duration, movement time, and movement initiation time) and performance-production (peak acceleration) measures and were then evaluated.

Results: Individuals with chronic stroke demonstrated significantly reduced performance outcomes (i.e., longer reaction time, burst duration, movement time, and movement initiation time) and performance production ability (i.e., smaller peak acceleration) compared to their healthy counterparts (p < 0.05) for both flexion- and abduction-reaching movements.

Conclusion: Our results are suggestive of post-stroke deficits in ipsilesional motor execution during a stand-reaching task. Based on these findings, it is essential to integrate ipsilesional UE training into rehabilitation interventions as this might aid functional reaching activities of daily living and could ultimately help community-dwelling chronic stroke survivors maintain their independent living.

慢性脑卒中对功能性手臂伸展的影响:量化同侧上肢的缺陷。

目的:本研究的目的是量化慢性脑卒中幸存者的同侧上肢(UE)站立能力(运动学和动力学)。方法:社区慢性中风幸存者(n=13)和年龄相似的健康成年人(n=13)进行屈曲和外展到达任务。使用来自原动机(前三角肌和中三角肌)的无线传感器对表面肌电图和加速度进行采样，并提供性能结果(反应时间、爆发持续时间、运动时间和运动开始时间)和性能产生(峰值加速度)测量，然后进行评估。结果:慢性中风患者在屈曲和外展动作方面的表现结果(即更长的反应时间、爆发持续时间、运动时间和运动开始时间)和表现产生能力(即更小的峰值加速度)均显著低于健康患者(p < 0.05)。结论:我们的研究结果提示卒中后同侧运动执行在站立任务中的缺陷。基于这些发现，有必要将创伤性脑卒中训练整合到康复干预中，因为这可能有助于日常生活的功能性活动，并最终帮助社区居住的慢性中风幸存者维持独立生活。

期刊介绍： Rehabilitation Research and Practice is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies in all areas of physical medicine and rehabilitation. The journal focuses on improving and restoring functional ability and quality of life to those with physical impairments or disabilities. In addition, articles looking at techniques to assess and study disabling conditions will be considered.
