Leg length discrepancy measurement is an essential part of musculoskeletal clinical assessment, and tape measurement is a common clinical method. This study aimed to systematically review the results of the findings of studies on validity and reliability of the tape measurement method and the quality of reporting the literature on this topic. A search was performed in PubMed, EBSCO, Science Direct, Web of Knowledge, Scopus, Embase, and Google Scholar using selected keywords from inception to December 2017.This systematic review was based on the PRISMA guideline. After a systematic selection process, the quality of the included studies was assessed independently by 2 reviewers using the Brink and Louw Scale for quality assessment. A total of 11 studies were finally considered for this systematic review. Two studies were about the validity of (a measurement tool) studies and 4 were reliability analysis only. Validity and reliability analyses were simultaneously applied to 5 studies. Also, 9 out of 11 studies were deemed to be of high quality based on Brink and Louw Scale. Studies showed high (ICC=0.7) to very high (ICC=0.9) levels of interrater and intrarater reliability. The validity of the methods ranged from low to very high depending on subjects. Tape measurement method has acceptable reliability and validity in healthy people, but it does not have acceptable validity in measuring obese people and patients with musculoskeletal disorders. Thus, using a suitable method for LLD leg length discrepancy measurement seems to be necessary for obese and individuals with leg length discrepancy.
腿长差异测量是肌肉骨骼临床评估的重要组成部分，而卷尺测量是一种常见的临床方法。本研究旨在系统回顾关于卷尺测量方法的有效性和可靠性以及该主题文献报告质量的研究结果。使用选定的关键词，在PubMed、EBSCO、科学Direct、Web of Knowledge、Scopus、Embase和谷歌学术上进行了从创刊到2017年12月的检索。本系统评价基于PRISMA指南。经过系统的筛选过程，由2名评审员使用Brink和Louw质量评估量表独立评估纳入研究的质量。本系统评价最终共纳入11项研究。两项研究是关于（一种测量工具）研究的有效性，4项仅为可靠性分析。5项研究同时应用了有效性和可靠性分析。此外，根据Brink和Louw量表，11项研究中有9项被认为质量较高。研究表明，评分者间和评分者内的可靠性水平较高（ICC = 0.7）至非常高（ICC = 0.9）。根据受试者的不同，这些方法的有效性范围从低到非常高。卷尺测量法在健康人群中具有可接受的可靠性和有效性，但在测量肥胖人群和肌肉骨骼疾病患者时，其有效性不可接受。因此，对于肥胖者和有腿长差异的个体，似乎有必要使用合适的方法进行腿长差异测量。
