This scoping review aims to map the different working definitions currently being used for the duration of acute, subacute and chronic low back pain (LBP), and to establish where these definitions originated and the rationale provided for the timeframes used.
Low back pain is a major social and economic problem worldwide. One of the most commonly used approaches to classify and manage patients with LBP is the traditional duration-based classification (acute, subacute and chronic). There are significant differences between studies in the timeframes used for what constitutes acute, subacute and chronic LBP. These discrepancies lead to heterogeneity in study results, making it difficult to compare or summarize findings.
Studies that include participants with non-specific LBP, regardless of sex, will be considered. Studies that include children or participants with specific causes of LBP will be excluded.
The following electronic databases will be searched: MEDLINE, Embase, CINAHL and PsycINFO. All types of studies will be included, provided they give a rationale for the definition of duration that they use. Studies will be limited to those published in English. Two independent reviewers will screen the retrieved articles against the eligibility criteria for the scoping review. A narrative synthesis will describe the definitions used in the study and the rationale given for the timeframes reported. This scoping review will give an insight into the background of the variation of timeframes used for duration-based classification of LBP.
本范围综述旨在梳理目前用于急性、亚急性和慢性腰痛（LBP）病程的不同工作定义，确定这些定义的出处以及所采用时间框架的依据。
腰痛是全球范围内的一个重大社会和经济问题。对腰痛患者进行分类和管理最常用的方法之一是传统的基于病程的分类（急性、亚急性和慢性）。在构成急性、亚急性和慢性腰痛的时间框架方面，不同研究之间存在显著差异。这些差异导致研究结果的异质性，使得难以比较或总结研究发现。
将纳入包含非特异性腰痛参与者的研究，无论性别如何。将排除包含儿童或有特定腰痛病因参与者的研究。
将检索以下电子数据库：MEDLINE、Embase、CINAHL和PsycINFO。将纳入所有类型的研究，前提是它们给出了所使用病程定义的依据。研究将限于以英文发表的研究。两名独立评审员将根据范围综述的纳入标准筛选检索到的文章。叙述性综合将描述研究中使用的定义以及所报告时间框架的依据。本范围综述将深入了解基于病程对腰痛进行分类时所用时间框架变化的背景。
