在过去的十年中，用于描述物理治疗服务结果变化的方法和科学已经变得更加完善。最近，重点不仅放在超出预期测量误差的变化上，而且还放在识别对患者和家庭的生活产生真实的影响的变化上。本文将重点介绍如何从这两个角度确定和解释“临床显著变化”的案例。作者还研究了如何在项目反应理论模型中使用项目地图来增强对内容水平变化的解释。为物理治疗师提供了建议，他们正在解释临床实践，病例报告和干预研究的变化。这些建议包括更多地应用指数，帮助解释临床显著变化对多个临床，研究，消费者和付款人社区的意义。
Over the past decade, the methods and science used to describe changes in outcomes of physical therapy services have become more refined. Recently, emphasis has been placed not only on changes beyond expected measurement error, but also on the identification of changes that make a real difference in the lives of patients and families. This article will highlight a case example of how to determine and interpret "clinically significant change" from both of these perspectives. The authors also examine how to use item maps within an item response theory model to enhance the interpretation of change at a content level. Recommendations are provided for physical therapists who are interpreting changes in the context of clinical practice, case reports, and intervention research. These recommendations include a greater application of indexes that help interpret the meaning of clinically significant change to multiple clinical, research, consumer, and payer communities.
