Physical activity (PA) is recommended to mitigate the symptoms of osteoarthritis (OA); however, this modality remains an unfamiliar construct for many patients and clinicians. Moreover, there can be confusion over the nuanced differences in terminology, such as exercise, sedentary behavior, and moderate intensity. The purpose of this scoping review is to provide a basic overview of PA including terminology, summarize the importance of PA for adults with OA, and discuss current gaps in the literature. Broadly, PA is defined as any energy expenditure from skeletal muscle above a resting level, and exercise is considered a type of PA that is planned, structured, and repetitive. Robust literature shows that PA has a modest protective effect on pain, functional limitation, and disability for OA, in addition to positive effects on a broad range of outcomes from mood and affect to mortality and morbidity in the general population. We provide recommendations for which measurement instruments can be used to record PA, both from a clinical and research perspective, as well as which metrics to employ for summarizing daily activity.
身体活动（PA）被推荐用于减轻骨关节炎（OA）的症状；然而，对于许多患者和临床医生来说，这种方式仍然是一个陌生的概念。此外，在术语上可能存在细微的差异，例如运动、久坐行为和中等强度，这也会引起混淆。本综述的目的是提供 PA 的基本概述，包括术语，总结 PA 对 OA 成人的重要性，并讨论文献中的当前差距。广义上，PA 被定义为骨骼肌在静息水平以上消耗的任何能量，而运动被认为是一种有计划、有结构和重复性的 PA。大量文献表明，PA 对 OA 的疼痛、功能受限和残疾有适度的保护作用，此外，对一般人群的情绪和情感、死亡率和发病率等广泛的结果也有积极影响。我们从临床和研究的角度提供了用于记录 PA 的测量工具的建议，以及用于总结日常活动的指标。
