Backward walking (BW) is otherwise known as retrowalking. As opposed to forward walking, BW is a countersequential exercise and is a common method of rehabilitation training and disease-assisted treatment. Studies have shown that BW has a helpful effect on improving lower limb proprioception, gait synergy and improving limb balance. Many studies have concluded that BW can improve the symptoms of patients with knee osteoarthritis (KOA) and can be used for rehabilitation and adjunctive treatment of KOA, but there is a lack of evidence-based medical evidence.This research aims to provide an update to the most recent available evidence on the effect of BW on patients with KOA .
Electronic databases, such as Ovid/MEDLINE, EMBASE, CINAHL, Scopus, Web of Science and PubMed, will be searched by us. We will include studies identified from citation until 12 May 2020 and will not be restricted by geographical setting. The search will not be limited to the language of the publication, but the study of human subjects. Randomised controlled trials (RCTs) on the BW training of KOA will be included, with outcome measures including pain, knee function or balance function. The quality of included RCTs will be evaluated according to the Cochrane Collaboration's risk of bias tool. A meta-analysis or systematic review will be performed to summarise the effects of BW training. We will perform sensitivity analysis on the sample size of RCTs, meta-regression analysis of the follow-up periods, dosages and baselines of outcome measures, and publication bias analysis.
Ethical approval is not required as this study will not involve confidential personal data. The results of this study will be disseminated through a peer-reviewed journal.

倒走（BW）也称为倒退行走。与向前行走相反，BW 是一种反向顺序运动，是康复训练和疾病辅助治疗的常用方法。研究表明，BW 对改善下肢本体感觉、步态协同和改善肢体平衡有帮助作用。许多研究得出结论，BW 可以改善膝骨关节炎（KOA）患者的症状，可用于 KOA 的康复和辅助治疗，但缺乏循证医学证据。本研究旨在提供最新的关于 BW 对 KOA 患者影响的可用证据更新。
我们将对 Ovid/MEDLINE、EMBASE、CINAHL、Scopus、Web of Science 和 PubMed 等电子数据库进行检索。我们将包括从引文到 2020 年 5 月 12 日确定的研究，并且不受地理位置的限制。搜索将不限于出版物的语言，但仅限于人体研究。将纳入 BW 训练对 KOA 的影响的随机对照试验（RCT），结局指标包括疼痛、膝关节功能或平衡功能。将根据 Cochrane 协作风险偏倚工具评估纳入 RCT 的质量。将对 BW 训练的效果进行荟萃分析或系统评价。我们将对 RCT 的样本量进行敏感性分析，对随访期、结局测量的剂量和基线进行荟萃回归分析，并进行发表偏倚分析。
由于本研究不涉及机密个人数据，因此不需要伦理批准。本研究的结果将通过同行评审的期刊传播。
