Abstract

Objectives: The aim of this study was to investigate the effects of a digitally supported physical activity (PA) intervention on pain, physical function, exercise adherence and quality of life in females with knee osteoarthritis (OA).

Methods: Thirty female participants with knee OA were randomly assigned to either a control group (n = 15) receiving patient education, smartwatch use, and a home exercise programme, or an intervention group (n = 15) receiving an additional digitally supported walking programme. The primary outcome measures were pain severity (Numerical Pain Rating Scale [NPRS]), physical function (Western Ontario and McMaster Universities Arthritis Index [WOMAC]) and exercise adherence. Secondary outcomes included quality of life (European Quality of Life Scale 5 Dimensions/EQ-5D-3L), daily step count and pain catastrophizing (Pain Catastrophizing Scale/PCS). Assessments were performed at baseline and after 8 weeks.

Results: The intervention group showed significantly greater improvements in pain severity (1.4 cm larger improvement on NPRS; p = 0.005), physical function (6.4-point larger improvement on WOMAC total score; p = 0.003) and daily step count (1548 steps larger improvement; p = 0.045) compared to the control group. Both groups demonstrated similar significant improvements in exercise adherence, pain catastrophizing, and quality of life (p < 0.05).

Conclusions: A digitally supported PA intervention, in addition to patient education and a home exercise programme, significantly improved pain, physical function and PA in females with knee OA. These findings support the efficacy of structured, supervised digital interventions for enhancing outcomes in this population. Future studies should explore strategies to enhance long-term adherence through digital PA interventions.

Trial registration: This study was conducted in compliance with the Declaration of Helsinki (Clinical Trial Registry Number: NCT05810376).

数字支持的身体活动干预对膝关节骨性关节炎的影响：一项随机对照试验。

目的：本研究的目的是调查数字支持的身体活动（PA）干预对女性膝关节骨关节炎（OA）患者疼痛、身体功能、运动依从性和生活质量的影响。方法：30名患有膝关节OA的女性参与者被随机分配到对照组（n = 15），接受患者教育、使用智能手表和家庭锻炼计划，或干预组（n = 15），接受额外的数字支持步行计划。主要结局指标为疼痛严重程度（数值疼痛评定量表[NPRS]）、身体功能（西安大略省和麦克马斯特大学关节炎指数[WOMAC]）和运动依从性。次要结局包括生活质量（欧洲生活质量量表5维度/EQ-5D-3L）、每日步数和疼痛加重（疼痛加重量表/PCS）。在基线和8周后进行评估。结果：干预组疼痛程度改善明显(NPRS改善1.4 cm；p = 0.005)、身体功能(WOMAC总分提高6.4分；P = 0.003)和每日步数(1548步较大改善；P = 0.045)。两组患者在运动依从性、疼痛灾难性和生活质量方面均表现出相似的显著改善(p结论：数字支持的PA干预，加上患者教育和家庭运动计划，可显著改善膝关节OA女性患者的疼痛、身体功能和PA。这些发现支持了结构化、有监督的数字干预措施对提高这一人群的治疗效果的有效性。未来的研究应该探索通过数字PA干预来提高长期依从性的策略。试验注册：本研究遵循赫尔辛基宣言（临床试验注册号：NCT05810376）进行。
