Objective

To compare change in self-efficacy for managing knee osteoarthritis (OA) pain and kinesiophobia after watching an educational video based on an empowerment and participatory discourse with a video based on a disease and impairment discourse.

Design

Two-arm randomised controlled trial with participants aged ≥45 years with knee pain (n = 589). Participants completed both baseline and follow-up outcomes and watched one randomly-allocated video (12-minute duration) during one 30–45-minute session within a single online survey. The experimental video presented evidence-based knee OA information using design and language that aimed to empower people and focus on activity participation to manage OA, while the control video presented similar information but with a disease and impairment focus. Primary outcome measures were Arthritis Self-Efficacy Scale pain subscale (range 0–10) and Brief Fear of Movement Scale for OA (range 6–24). Secondary outcomes were expectations about prognosis and physical activity benefits, perceived importance and motivation to be physically active, knee OA knowledge, hopefulness for the future, level of concern and perceived need for surgery.

Results

Compared to control (n = 293), the experimental group (n = 296) showed improved self-efficacy for managing OA pain (mean difference 0.4 [95%CI 0.2, 0.6] units) and reduced kinesiophobia (1.6 [1.1, 2.0] units). The experimental group also demonstrated greater improvements in all secondary outcomes apart from hopefulness, which was high in both groups.

Conclusion

An educational video based on an empowerment and participatory discourse improved pain self-efficacy and reduced kinesiophobia in people with knee OA more than a video based on a disease and impairment discourse.

两个教育视频对膝骨关节炎患者自我效能感和运动恐惧症的比较效果：一项在线随机对照试验

客观的

比较观看基于赋权和参与式话语的教育视频与基于疾病和损伤话语的视频后，管理膝关节骨关节炎 (OA) 疼痛和运动恐惧症的自我效能的变化。

设计

两臂随机对照试验，受试者年龄≥45 岁，患有膝关节疼痛（n = 589）。参与者完成了基线和后续结果，并在一次在线调查中的一个 30-45 分钟会话期间观看了一个随机分配的视频（12 分钟持续时间）。实验视频使用旨在赋予人们权力并专注于活动参与来管理 OA 的设计和语言提供了基于证据的膝关节 OA 信息，而控制视频则提供了类似的信息，但重点关注疾病和损伤。主要结果测量是关节炎自我效能量表疼痛分量表（范围 0-10）和 OA 运动恐惧量表（范围 6-24）。次要结果是对预后和身体活动益处的预期、对身体活动的重要性和动机的感知、膝关节 OA 知识、

结果

与对照组 (n = 293) 相比，实验组 (n = 296) 显示出改善 OA 疼痛管理的自我效能（平均差 0.4 [95%CI 0.2, 0.6] 单位）和减少运动恐惧症（1.6 [1.1, 2.0]单位）。实验组的所有次要结果也显示出更大的改善，除了希望在两组中都很高。

结论

基于赋权和参与性话语的教育视频比基于疾病和损伤话语的视频更能提高膝关节 OA 患者的疼痛自我效能并减少运动恐惧症。
