Aging of skeletal muscles results in a cascade of events negatively affecting muscle mass, strength, and function, leading to reduced mobility, increased risk of falls, disability, and loss of independence. To date, different methods are used to assess muscle mechanical function, tensiomyography (TMG) being one of them. The aim of this review was twofold: to summarize the evidence-based usefulness of tensiomyography in older adults and to establish reference values for the main tensiomyography parameters in older adults. The PubMed, Web of Science, SPORTDiscus, and tensiomyography databases were searched from inception until 25 December 2022. Studies investigating older adults (aged 60+ years) that reported tensiomyography-derived parameters such as contraction time (Tc) and/or maximal displacement (Dm) were included. Methodological quality was assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. In total, eight studies satisfied the inclusion criteria. Tensiomyography has been used on different groups of older adults, including asymptomatic, master athletes, patients with peripheral arterial disease, and patients with end-stage knee osteoarthritis with a mean age of 71.5 ± 5.38 (55.7% male subjects). The most evaluated were leg muscles such as vastus lateralis (VL), gastrocnemius medialis (GM), and biceps femoris (BF). The present review demonstrates that tensiomyography is used to assess neuromuscular function in asymptomatic and diseased older adults. When compared to asymptomatic individuals, power master athletes, knee osteoarthritis patients, and patients diagnosed with peripheral arterial disease have the shortest Tc in BF, VL, and GM muscles, respectively. On the other hand, endurance master athletes showed the longest Tc in all three evaluated muscles. Less mobile, nursing-home residents showed higher Dm in VL and BF, while lower Dm in GM than the asymptomatic group. The knee osteoarthritis group showed the largest Dm in BF and VL while having the smallest Dm in GM. Tensiomyography can serve as a valuable tool for assessing neuromuscular function in older adults. The method is sensitive to muscle composition, architecture, and (pre) atrophic changes of the skeletal muscles and might be responsive to muscle quality changes in aging and diseased populations. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=402345, identifier CRD42023402345.
骨骼肌衰老会引发一系列对肌肉质量、力量和功能产生负面影响的事件，导致活动能力下降、跌倒风险增加、残疾以及失去独立性。迄今为止，人们使用了不同方法来评估肌肉机械功能，张力肌电图（TMG）就是其中之一。本综述的目的有两个：总结张力肌电图在老年人中的循证实用性，并确定老年人主要张力肌电图参数的参考值。检索了PubMed、科学网、SPORTDiscus和张力肌电图数据库，检索时间从建库至2022年12月25日。纳入了调查60岁及以上老年人且报告了张力肌电图衍生参数（如收缩时间（Tc）和/或最大位移（Dm））的研究。使用观察性队列研究和横断面研究质量评估工具评估方法学质量。总共八项研究符合纳入标准。张力肌电图已应用于不同老年人群体，包括无症状者、大师级运动员、外周动脉疾病患者以及终末期膝关节骨关节炎患者，平均年龄为71.5±5.38岁（男性受试者占55.7%）。评估最多的是腿部肌肉，如股外侧肌（VL）、腓肠肌内侧头（GM）和股二头肌（BF）。本综述表明，张力肌电图用于评估无症状和患病老年人的神经肌肉功能。与无症状个体相比，力量型大师级运动员、膝关节骨关节炎患者和被诊断为外周动脉疾病的患者，其BF、VL和GM肌肉的Tc分别最短。另一方面，耐力型大师级运动员在所有三块被评估肌肉中的Tc最长。活动能力较差的养老院居民在VL和BF中的Dm较高，而在GM中的Dm低于无症状组。膝关节骨关节炎组在BF和VL中的Dm最大，而在GM中的Dm最小。张力肌电图可作为评估老年人神经肌肉功能的有价值工具。该方法对骨骼肌的肌肉组成、结构和（前期）萎缩变化敏感，可能对衰老和患病群体的肌肉质量变化有反应。https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=402345，标识符CRD42023402345 。
