Abstract

The aim of this systematic review was to identify the association between muscle strength, activation, and structure of the hip abductor-adductor muscles and balance and mobility tasks in individuals post stroke. The present systematic review is comprised of 37 research articles, with 911 individuals that had a stroke. The extracted data included the study population, sample size, sex, stroke side of paresis, time poststroke, and evaluated measurements. We concluded that stronger hip abductors and adductors (both paretic and nonparetic legs) resulted in quicker voluntary step, and faster walking speed and cadence. Also, stronger paretic hip abductors were associated with a faster completion of the timed up and go test, higher ambulation ability, better control of the centre of mass, and quicker stair climbing. Overall, it demonstrated a lateral induced step to the paretic side, increased muscle activation of the gluteus medius of the paretic leg, and increased nonparetic hip abductor muscle activation. The strength and ability to activate the hip abductor and adductor muscles appears to be related to better performance during balance or mobility tasks in individuals with stroke. Therefore, the present systematic review results suggest that improving muscle strength and activation of the hip abductor and adductor muscles might help individuals with stroke to avoid falls.
髋外展肌和内收肌在中风后平衡和活动任务中的重要性:一项系统综述
本系统综述的目的是确定中风后个体肌肉力量、激活和髋外收肌结构与平衡和活动任务之间的关系。本系统综述包括37篇研究文章,涉及911例中风患者。提取的数据包括研究人群、样本量、性别、卒中侧轻瘫、卒中后时间和评估测量。我们的结论是,更强的髋外展肌和内收肌(跛腿和非跛腿)导致更快的自主步伐,更快的步行速度和节奏。此外,更强的髋外展肌与更快地完成定时上走测试、更高的行走能力、更好地控制重心和更快地爬楼梯有关。总的来说,它显示了向麻痹侧的横向诱导步,增加了麻痹腿臀中肌的肌肉激活,增加了非麻痹性髋外展肌的激活。激活髋关节外展肌和内收肌的力量和能力似乎与中风患者在平衡或活动任务中的更好表现有关。因此,目前的系统综述结果表明,提高肌肉力量和髋关节外展肌和内收肌的激活可能有助于中风患者避免跌倒。
