Abstract

BACKGROUND

To examine the correlation between physical performance and muscle strength and the variables obtained from tensiomyography and myotonometry.

METHODS

Fifty-two older adults able to complete functional tests participated in this observational study. Variables of maximal radial muscle displacement (Dm) and contraction time (Tc) (using tensiomyography) and muscle stiffness (using myotonometry) of the rectus femoris and vastus lateralis muscles were assessed. Physical performance (Short Physical Performance Battery, Timed Up and Go, Five Times Sit to Stand, and walking speed), isometric knee extension strength, and grip strength were assessed. A correlation analysis was performed between all the variables.

RESULTS

A significant correlation between the Short Physical Performance Battery and the rectus femoris (rho = 0.491) and vastus lateralis Dm (rho = 0.329) was found. Significant correlations between the Five Times Sit to Stand Test and the Dm values of the rectus femoris (rho = -0.340) and Dm (rho = -0.304), and stiffness (rho = -0.345) in the vastus lateralis, were also found. No significant correlations were found between tensiomyography and myotonometry, the Timed Up and Go, and walking speed, nor between tensiomyography and myotonometry and grip strength or isometric knee extension strength.

CONCLUSIONS

Functional tests should be prioritized in the assessment of older adults, but further research into muscle quality using technology is advisable.

摘要

背景

研究身体机能与肌肉力量之间的相关性，以及从张力肌电图和肌动测量法获得的变量之间的相关性。

方法

52名能够完成功能测试的老年人参与了这项观察性研究。评估了股直肌和股外侧肌的最大桡侧肌肉位移（Dm）和收缩时间（Tc）（使用张力肌电图）以及肌肉僵硬度（使用肌动测量法）等变量。评估了身体机能（简短身体机能量表、计时起立行走测试、五次坐立测试和步行速度）、等长膝关节伸展力量和握力。对所有变量进行了相关性分析。

结果

发现简短身体机能量表与股直肌Dm（rho = 0.491）和股外侧肌Dm（rho = 0.329）之间存在显著相关性。还发现五次坐立测试与股直肌Dm值（rho = -0.340）、股外侧肌Dm（rho = -0.304）和僵硬度（rho = -0.345）之间存在显著相关性。在张力肌电图和肌动测量法、计时起立行走测试和步行速度之间，以及张力肌电图和肌动测量法与握力或等长膝关节伸展力量之间未发现显著相关性。
