Hand grip strength (HGS) is used for the diagnosis of sarcopenia and frailty. Several factors have been shown to influence HGS values during measurement. Therefore, variations in the protocols used to assess HGS, as part of the diagnosis of sarcopenia and frailty, may lead to the identification of different individuals with low HGS, introducing bias. The aim of this systematic review is to gather all the relevant studies that measured HGS to diagnose sarcopenia and frailty and to identify the differences between the protocols used.
A systematic review was carried out following the recommendations of The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. PubMed and Web of Science were systematically searched, until August 16, 2016. The evidence regarding HGS measurement protocols used to diagnose sarcopenia and frailty was summarised and the most recent protocols regarding the procedure were compared.
From the described search 4393 articles were identified. Seventy-two studies were included in this systematic review, in which 37 referred to sarcopenia articles, 33 to frailty and two evaluated both conditions. Most studies presented limited information regarding the protocols used.
The majority of the studies included did not describe a complete procedure of HGS measurement. The high heterogeneity between the protocols used, in sarcopenia and frailty studies, create an enormous difficulty in drawing comparative conclusions among them.
握力（HGS）用于诊断肌肉减少症和虚弱。已表明有几个因素会在测量期间影响HGS值。因此，作为肌肉减少症和虚弱诊断一部分的评估HGS所用方案的差异，可能会导致识别出不同的低HGS个体，从而引入偏差。本系统评价的目的是收集所有测量HGS以诊断肌肉减少症和虚弱的相关研究，并确定所用方案之间的差异。
按照系统评价和Meta分析的首选报告项目（PRISMA）声明的建议进行系统评价。对PubMed和科学网进行了系统检索，直至2016年8月16日。总结了用于诊断肌肉减少症和虚弱的HGS测量方案的证据，并比较了有关该程序的最新方案。
通过上述检索共识别出4393篇文章。本系统评价纳入了72项研究，其中37项涉及肌肉减少症文章，33项涉及虚弱，2项评估了这两种情况。大多数研究提供的有关所用方案的信息有限。
纳入的大多数研究未描述HGS测量的完整程序。在肌肉减少症和虚弱研究中，所用方案之间的高度异质性给在它们之间得出比较性结论造成了巨大困难。
