Effect of backward walking training on knee osteoarthritis: protocol of a systematic review and meta-analysis

Abstract

IntroductionBackward 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 .Methods and analysesElectronic 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.Ethics and disseminationEthical 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.PROSPERO registration numberCRD42020185694.

Evidence-based rehabilitation medicine: definition, foundation, practice and development

“…However, Wu et al. [ 45 ] found a lack of evidence in EBM regarding the use of backward walking, also known as retro-walking, despite its potential benefits in symptom improvement, rehabilitation, and adjunctive treatment for KOA.…”

The Effect of Contrast Bath Therapy and Knee Pad Device on Pain, Range of Motion, and Functional Disability in Patients With Osteoarthritis Knee: A Randomized Control Trial

“…Many recent studies that are now available have found that retro-walking, also known as backward walking, can lessen knee OA patients' symptoms and is one of their kinetic options. Retro-walking, which is counter-sequential to forward walking and has a beneficial effect on limb balance, gait synergy, and lower limb proprioception, is a useful exercise [30]. A two-minute walk test is also used in this study to assess the functional capacity of the patients.…”
