Abstract

Background

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.

Methods

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.

Findings

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.

Interpretation

Measurements of Knee Extension Strength and Hip Extension Strength may potentially serve as a promising method for sarcopenia screening.

下肢肌肉力量测量的创新设备：在肌肉减少症筛查中的设计与应用。

背景：握力已被确立为一种实用有效的筛查和诊断肌肉减少症的方法。人们认识到，随着年龄的增长，下肢肌肉质量的下降比上肢更明显。然而，由于与测量握力相比，评估下肢肌肉力量的固有复杂性，这些评估尚未被普遍用于肌肉减少症筛查。方法：我们使用设计用于下肢肌肉力量评估的便携式设备测量了98名参与者的前足力量、脚跟力量、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力临界值和握力筛查肌肉减少症的效果。研究结果：通过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 N和121.7 N，而女性分别为91.6 N和90.4 N。在调整了年龄和体重的二元logistic回归模型中，发现男性和女性的膝关节伸展力量和髋关节伸展力量与肌肉减少症有关。此外，使用膝关节伸展力量或髋部伸展力量切断值筛查肌肉减少症的效果优于单独使用握力，并且膝关节伸展力量和髋部伸展力量切断值联合筛查肌肉减少症的效果最好。解释：测量膝关节伸展强度和髋关节伸展强度可能是一种很有前途的肌肉减少症筛查方法。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
