Knee osteoarthritis (KOA) is a prevalent chronic condition among the adult individuals, leading to pain, joint stiffness, and muscle weakness. Resistance training is an effective strategy for alleviating KOA-related symptoms and improving physical function. However, the efficacy of such interventions also depends on their fidelity, ensuring that the prescribed exercise protocols are followed correctly. This study aimed to assess the fidelity of a structured strength training program and its effects on pain management in adult individuals with KOA.
A total of 72 adults (mean age = 56.27 ± 4.89 years), approximately 40% of whom were overweight, were randomly assigned to either a strength training group (n = 37) or a control group (n = 35). Quantitative data were collected using the Knee Injury and Osteoarthritis Outcome Score (KOOS), while qualitative data on intervention fidelity were obtained through self-reported adherence to daily home workouts.
The results indicated a significant improvement in KOOS scores in the strength training group compared to the control group (p < 0.001). Participants consistently adhere to the prescribed exercise program in their home workouts. These findings highlight the importance of intervention fidelity in strength training programs for adult individuals with KOA, emphasizing its role in optimizing health outcomes.
This study contributes to the growing evidence supporting structured strength training as a viable strategy for managing KOA-related symptoms and enhancing physical function in ageing populations.
膝关节骨关节炎（KOA）是成年人中普遍存在的慢性疾病，会导致疼痛、关节僵硬和肌肉无力。阻力训练是缓解KOA相关症状和改善身体功能的有效策略。然而，此类干预措施的效果还取决于其保真度，即确保正确遵循规定的运动方案。本研究旨在评估结构化力量训练计划的保真度及其对成年KOA患者疼痛管理的影响。
总共72名成年人（平均年龄=56.27±4.89岁），其中约40%超重，被随机分配到力量训练组（n=37）或对照组（n=35）。使用膝关节损伤和骨关节炎结局评分（KOOS）收集定量数据，同时通过自我报告的家庭日常锻炼依从性获得关于干预保真度的定性数据。
结果表明，与对照组相比，力量训练组的KOOS评分有显著改善（p<0.001）。参与者在家庭锻炼中始终坚持规定的锻炼计划。这些发现凸显了干预保真度在成年KOA患者力量训练计划中的重要性，强调了其在优化健康结局中的作用。
本研究为越来越多的证据提供了补充，支持结构化力量训练作为管理KOA相关症状和增强老年人群身体功能的可行策略。
