Abstract

INTRODUCTION

Motor variability is an important feature when performing repetitive movement, and in asymptomatic people functional tasks are typically performed with variable motor patterns. However, in the presence of chronic non-specific low back pain (LBP), people often present with different motor control strategies than those without pain. Movement variability has been assessed using a wide range of variables, including kinetic and kinematic components of motion. This has resulted in a wide range of findings reported in the literature and some contradicting results. Therefore, the aim of this systematic review is to investigate whether the amount and structure of motor variability are altered in people with chronic non-specific LBP, during both repetitive non-functional and functional tasks.

METHODS AND ANALYSIS

This protocol for a systematic review is informed by Cochrane guidelines and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. MEDLINE, EMBASE, CINAHL, ZETOC, Web of Science, PubMed and Scopus will be searched from their inception to December 2020 along with a comprehensive search of grey literature and key journals. Two independent reviewers will conduct the search, extract the data, assess risk of bias (using the Downs and Black Scale) for the included studies and assess overall quality of evidence based on Grading of Recommendations, Assessment, Development and Evaluation guidelines. Meta-analysis will be conducted if deemed appropriate. Alternatively, a narrative synthesis will be conducted and evidence summarised as an increase, decrease or no change in the motor variability of people with LBP compared with healthy controls.

ETHICS AND DISSEMINATION

This study raises no ethical issues. Results will be submitted for publication in a peer review journal and presented at conferences.

摘要

简介

在进行重复性运动时，运动变异性是一个重要特征，在无症状人群中，通常采用可变的运动模式来完成功能性任务。然而，在患有慢性非特异性下腰痛（LBP）的人群中，他们通常表现出与无疼痛人群不同的运动控制策略。运动变异性已通过广泛的变量进行评估，包括运动的动力学和运动学成分。这导致文献中报告了广泛的发现，有些结果相互矛盾。因此，本系统评价的目的是研究在慢性非特异性 LBP 人群中，无论是在重复性非功能性任务还是功能性任务中，运动变异性的数量和结构是否发生改变。

方法和分析

本系统评价方案是根据 Cochrane 指南制定的，并按照系统评价和荟萃分析报告的首选条目进行报告。将从建库开始到 2020 年 12 月，在 MEDLINE、EMBASE、CINAHL、ZETOC、Web of Science、PubMed 和 Scopus 中进行搜索，并对灰色文献和主要期刊进行全面搜索。两名独立的审查员将进行搜索、提取数据、评估纳入研究的偏倚风险（使用 Downs 和 Black 量表），并根据推荐、评估、制定和评估指南评估总体证据质量。如果认为合适，将进行荟萃分析。或者，将进行叙述性综合，并根据与健康对照组相比，LBP 患者的运动变异性增加、减少或无变化来总结证据。
