The primary aim is to compare the effects of backward walking exercise to forward walking exercise on knee pain, knee functions, and thigh muscle strength in individuals with mild to moderate knee osteoarthritis using lower body positive pressure, in addition to mobility functions, balance, and self-reported health status.
The study is a single blind randomized clinical trial with two independent groups. This study will enroll 26 participants with mild to moderate knee osteoarthritis. The participants will be randomized into either experimental group (backward walking exercise) or control group (forward walking exercise). Both groups will use lower body positive pressure treadmill for walking exercise. Both groups will perform regular conventional exercise and worm-up exercise before walking exercise. The treatment will be three times a week for six weeks. Walking session will be up to 30 min each session. Data collection will be collected during pre- and post- intervention including primary outcomes including numeric pain rating scale (NPRS), knee injury and osteoarthritis outcome score (KOOS), and thigh muscle strength test. The secondary outcomes include five times sit to stand test (FTSTS), 3-meter backward walk test (3MBWT), timed up and go test (TUG), four square step test (FSST), functional reach test (FRT), 10-meter walk test (10-MWT), six minute walk test (6MWT), medical outcomes study short form 12 (SF-12), patient health questionnaire -9 (PHQ-9), and rapid assessment of physical activity (RAPA). An independent t-test will be used to evaluate the effect of treatment on the outcome measures.
Not applicable.
Using lower body positive pressure may have promising results against knee osteoarthritis. Moreover, walking backward exercise using lower body positive pressure might add more benefits to individuals with knee osteoarthritis and help clinicians in decision making.

本研究旨在比较使用下肢正压的后向行走和前向行走对轻度至中度膝骨关节炎患者的膝关节疼痛、膝关节功能和大腿肌肉力量的影响，并评估其对活动能力、平衡能力和自我报告的健康状况的影响。
本研究为单盲随机临床试验，分为两组。共纳入 26 名轻度至中度膝骨关节炎患者，随机分为实验组（后向行走）和对照组（前向行走）。两组均使用下肢正压跑步机进行行走训练。两组在行走训练前均进行常规常规运动和热身运动。治疗方案为每周 3 次，共 6 周。每次行走训练时长 30 分钟。在干预前后（包括基线时）收集主要结局指标，包括数字疼痛评分量表（NPRS）、膝关节损伤和骨关节炎结局评分（KOOS）和大腿肌肉力量测试，次要结局指标包括五次坐站测试（FTSTS）、3 米向后行走测试（3MBWT）、计时起立行走测试（TUG）、四方步测试（FSST）、功能性伸展测试（FRT）、10 米步行测试（10-MWT）、6 分钟步行测试（6MWT）、健康调查简表 12 项（SF-12）、患者健康问卷 -9 项（PHQ-9）和快速活动评估（RAPA）。采用独立样本 t 检验评估治疗对结局指标的影响。
无
使用下肢正压可能对膝骨关节炎有一定的治疗效果。此外，使用下肢正压的后向行走可能对膝骨关节炎患者有更多的益处，并有助于临床医生进行决策。
本研究已在 ClinicalTrials.gov 注册（ID：NCT05585099）。
