Grip Strength has been established as a practical and efficient method for screening and diagnosing sarcopenia. It is recognized that with advancing age, there is a more significant decline in lower limb muscle mass compared to the upper limb. However, due to the inherent complexity of assessing lower limb muscle strength compared to measuring Grip Strength, these assessments have not been universally adopted for sarcopenia screening.
We measured the Forefoot Strength, Heel Strength, Knee Extension Strength, and Hip Extension Strength in 98 participants using portable equipment designed for lower limb muscle strength assessment. We compared the efficacy of using lower limb muscle strength cutoff values with grip strength for the screening of sarcopenia.
The optimal cutoff values for screening sarcopenia in males using Knee Extension Strength and Hip Extension Strength were 140.1 N and 121.7 N, respectively, while for females they were 91.6 N and 90.4 N, respectively. In binary logistic regression models adjusted for age and body weight, Knee Extension Strength and Hip Extension Strength were found to be associated with sarcopenia in both males and females. Moreover, the efficacy of sarcopenia screening using Knee Extension Strength or Hip Extension Strength cutoff values was superior to that of grip strength alone, and the combination of Knee Extension Strength and Hip Extension Strength cutoff values yielded the best results for sarcopenia screening.
Measurements of Knee Extension Strength and Hip Extension Strength may potentially serve as a promising method for sarcopenia screening.
握力已被确立为一种用于筛查和诊断肌肉减少症的实用且有效的方法。人们认识到，随着年龄的增长，与上肢相比，下肢肌肉量的下降更为显著。然而，由于与测量握力相比，评估下肢肌肉力量具有内在的复杂性，这些评估尚未被普遍用于肌肉减少症的筛查。
我们使用专为评估下肢肌肉力量设计的便携式设备，测量了98名参与者的前足力量、足跟力量、膝关节伸展力量和髋关节伸展力量。我们比较了使用下肢肌肉力量临界值与握力进行肌肉减少症筛查的效果。
使用膝关节伸展力量和髋关节伸展力量筛查男性肌肉减少症的最佳临界值分别为140.1牛和121.7牛，而女性的最佳临界值分别为91.6牛和90.4牛。在根据年龄和体重进行调整的二元逻辑回归模型中，发现膝关节伸展力量和髋关节伸展力量在男性和女性中均与肌肉减少症相关。此外，使用膝关节伸展力量或髋关节伸展力量临界值进行肌肉减少症筛查的效果优于单独使用握力，并且膝关节伸展力量和髋关节伸展力量临界值的组合在肌肉减少症筛查中产生了最佳结果。
膝关节伸展力量和髋关节伸展力量的测量可能有望成为一种用于肌肉减少症筛查的方法。
