摘要

之前的一项研究报告指出,腘绳肌和股四头肌之间的同心力量失衡与老年人跌倒有关。鉴于同心力量的测量可能不如等长力量方便,因此测试等长腘绳肌-股四头肌力量失衡是否与老年人跌倒有关很有意义。本研究试图探讨腘绳肌-股四头肌比率是否能区分社区老年人中的跌倒者和非跌倒者。这项横断面研究共纳入了 111 名老年人。研究人员测量了他们的等长膝关节力量(伸肌和屈肌)。根据过去一年的跌倒史,他们被分为跌倒者(至少跌倒过一次)和非跌倒者(没有跌倒过)。比较了跌倒组和非跌倒组的腘绳肌-股四头肌比率。接受者操作特征分析用于确定腘绳肌-股四头肌比率的临界值,该值能够对跌倒者和非跌倒者进行最佳分类。跌倒者的腘绳肌-股四头肌比率明显低于非跌倒者(p = 0.008)。接受者操作特征分析表明,0.733 是区分跌倒者和非跌倒者的最佳比率,准确率为 64.0%。腘绳肌-股四头肌比率每降低 0.1 个单位,跌倒的概率就会增加 1.30 倍。在评估老年人跌倒风险时,腘绳肌-股四头肌比率可作为额外的跌倒风险因素。小于 0.733 的腘绳肌-股四头肌比率可能表明跌倒风险较高。

Hamstrings-quadriceps strength ratio could be related to falls in community-living older adults

A prior study reported that the concentric strength imbalance between hamstrings and quadriceps is associated with falls in older adults. Given that the concentric strength may not be measured as conveniently as the isometric strength, it is meaningful to test whether the isometric hamstring-quadricep strength imbalance is related to falls among older adults. This study sought to explore whether the hamstrings-quadriceps ratio could differentiate fallers from non-fallers in community-dwelling older adults. One hundred and eleven older adults were included in this cross-sectional study. Their isometric knee joint strength capacity (extensors and flexors) was measured. Based on their fall history in the past year, they were classified as fallers (at least one fall) or non-fallers (no fall). The hamstrings-quadriceps ratio was compared between the faller and non-faller groups. The receiver operating characteristic analysis was used to determine the cutoff value of the hamstrings-quadriceps ratio able to best classify fallers and non-fallers. Fallers showed a significantly lower hamstrings-quadriceps ratio than non-fallers (p = 0.008). The receiver operating characteristic analysis identified 0.733 as the best ratio to differentiate fallers from non-fallers with an accuracy of 64.0 %. A 0.1-unit reduction in the hamstrings-quadriceps ratio increases the probability of falling by a factor of 1.30. The hamstrings-quadriceps ratio could be used as an additional fall risk factor when assessing the risk of falls among older adults. A smaller than 0.733 hamstring-quadriceps ratio may indicate a high risk of falls.
