To determine the effectiveness of a self-management support intervention on knee functional status and health-related quality of life among middle-age women with knee osteoarthritis.
Randomized controlled trial.
The participants were 40 middle-aged women who had been clinically diagnosed with knee osteoarthritis for more than 3 months and randomly assigned into intervention and control groups equally. After IRB approval code 02-05-2562 was obtained, data collection was carried out from July - November 2019 at the Outpatient Department of Orthorpedics, Thasala Hospital, Thailand. The modified Thai version of the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and the Short Form Survey (SF-36) were used to measure knee functional status and health-related quality of life at baseline (T1), immediately after completing the intervention (T2) and 4 weeks after the intervention (T3). The participants in the intervention group received a self-management support program developed by the researcher based on the Individual and Family Self-Management Theory and a review of related literature plus routine care. The implementation consisted of eight sessions over 4 weeks. The control group received only routine care from the hospital. Two-way repeated measure ANOVAs were used to analyze the data.
The findings revealed that the participants in the intervention group had better knee functional status and HRQOL than those in the control group at follow-up. Additionally, in the intervention group, both knee functional status and HRQOL significantly improved from pre- to post-intervention and follow-up.
For women, the prevalence rate of knee OA rises dramatically post-menopause due to lower oestrogen levels. Policy makers and healthcare providers could obtain and promote this intervention as part of standard practice. This should lead to improved knee functional status and HRQOL among middle-aged women.

目标: 确定自我管理支持干预对中年膝骨关节炎妇女膝关节功能状态和健康相关生活质量的有效性。 设计: 随机对照试验。 方法: 研究对象为40名临床诊断为膝关节骨性关节炎超过3个月的中年妇女,她们被随机分到干预组和对照组。获得IRB批准代码02-05-2562后,于2019年7月至11月在泰国塔萨拉医院矫形门诊部进行数据收集。采用改良的泰版西安大略省和麦克马斯特大学骨关节炎指数(WOMAC)和简式调查(SF-36)测量基线(T1)、完成干预(T2)和干预后4周(T3)的膝关节功能状态和健康相关的生活质量。干预组的参与者接受了研究人员根据个人和家庭自我管理理论制定的自我管理支持计划,并查阅了相关文献和常规护理。实施包括4周时间进行八个采访环节。对照组仅接受医院常规护理。采用双向重复测量方差分析法对数据进行分析。 结果: 结果显示,在随访中,干预组的参与者的膝关节功能状态和健康相关生命质量(HRQoL)都比对照组好。此外,在干预组中,干预前后和随访期间,膝关节功能状态和健康相关生命质量(HRQoL)均显著改善。 结论: 研究结果表明,这种自我管理支持干预有效。 影响: 对女性来说,绝经后由于雌激素水平较低,膝关节骨性关节炎的患病率急剧上升。作为标准实践的一部分,政策制定者和医疗保健提供者可以获得并促进这种干预措施。这将改善中年妇女的膝关节功能状态和健康相关生命质量(HRQoL)。.
The findings indicate that this self-management support intervention is effective.
