Studying Physical Activity Rewards and Telephonic Active Coaching

体力活动(PA)，被定义为比休息需要更多能量的任何身体运动 改善膝骨性关节炎(OA)患者的疼痛和功能。美国疾病控制和预防中心 预防PA指南适用于所有年龄段的成年人，包括那些患有骨性关节炎的人，建议每周至少150分钟 中度至剧烈的PA。然而，对PA指南的遵守情况很差，特别是在有膝盖的人中 骨关节炎。全膝关节置换术(TKR)被广泛用于缓解疼痛和改善患者的功能 晚期膝骨性关节炎。鉴于对将军澳支线的大量投资，以及有丰富的证据证明公共交通的好处， 如果TKR接受者变得更活跃，TKR的值可能会大幅增加。在这 应用我们提出关键规划活动来设计和开发多中心临床方案 尝试解决创新假设，即TKR之后的时期提供了一个机会之窗 改变对PA的基本态度和信念。我们假设小规模的经济激励加上 有了定期的支持性辅导，将导致行为的改变，并有助于遵守PA的指导方针。这个 规划活动包括：(1)制定研究方案和管理材料，以指导研究 业务及其监测；(2)开展招生准备活动，收集关于以下方面的数据 来自潜在中心的合格受试者并最终确定提供者和中心的选择，(3)设备的选择 客观地监测PA进行测试，并选择最符合研究目的的监测仪，(4) 开发教练干预材料，以标准化干预并测试其交付给 优化可靠性，(5)制定财务激励的机制、协议和时间表 干预措施，以优化达到巴勒斯坦权力机构里程碑的财政奖励的时间和数额，(6) 最终确定评估工具，以确定和评估工具和监测协议，以及(7)创建 制定标准化的数据捕获计划和数据监测系统，以 优化精确度，最大限度地减少缺失元素。具体地说，我们将测试以下假设： 经济奖励可以抵消对巴勒斯坦权力机构承诺所固有的满足感的延迟，这些奖励 再加上健康教练的定期支持和指导，将进一步提高参与率 并提高对PA指南的遵从性。成功完成这些规划活动将 定位研究团队，以成功实施高度重要的创新个性化干预 建立在健康教练和行为经济学的原则之上。

Physical activity (PA), defined as any body movement that requires more energy than resting, has been shown to improve pain and function in persons with knee osteoarthritis (OA). Center for Disease Control and Prevention PA guidelines for adults of all ages including those with OA recommend at least 150 min/week of moderate-to-vigorous PA. However, adherence to PA guidelines is poor, particularly among persons with knee OA. Total knee replacement (TKR) is widely used to relieve pain and improve function in patients with advanced knee OA. Given the large investment in TKR and the rich evidence documenting the benefits of PA, the value of TKR could be increased substantially if TKR recipients became more physically active. In this application we propose key planning activities to design and develop the protocols for a multicenter clinical trial to address the innovative hypothesis that the period following TKR presents a window of opportunity to change fundamental attitudes and beliefs regarding PA. We hypothesize that small financial incentives coupled with regular supportive coaching will induce behavior change and facilitate adherence to PA guidelines. The planning activities include: (1) development of study protocols and regulatory materials to guide the study operations and its monitoring, (2) undertaking enrollment preparation activities to gather data on number of eligible subjects from potential centers and finalize selection of providers and centers, (3) selection of devices to objectively monitor PA to test and to select the monitor that fits the purpose of the study the best, (4) development of coaching intervention materials to standardize the intervention and test its delivery to optimize reliability, (5) development of the mechanisms, protocols, and schedules for the financial incentives intervention to optimize the timing and amount of the financial rewards for meeting PA milestones, (6) finalization of assessment tools to determine and assessment tools and monitoring protocols, and (7) creation of a data management plan to develop a standardized data capture plan and data monitoring system to optimize accuracy and minimize missing elements. Specifically, we will test the hypothesis that immediate financial rewards can offset the delay in gratification inherent in a commitment to PA and that these rewards coupled with regular support and guidance from health coaching will further increase the rate of engagement in PA and improve compliance with PA guidelines. Successful completion of these planning activities will position the research team to execute successfully a highly significant and innovative personalized intervention built on the principles of health coaching and behavioral economics.
