The process of evidence-based practice (EBP) guides clinicians in the integration of individual clinical expertise, patient values and expectations, and the best available evidence. Becoming proficient with this process takes time and consistent practice, but should ultimately lead to improved patient outcomes. The EBP process entails 5 steps: (1) formulating an appropriate question, (2) performing an efficient literature search, (3) critically appraising the best available evidence, (4) applying the best evidence to clinical practice, and (5) assessing outcomes of care. This first commentary in a 2-part series will review principles relating to steps 1, 2, and 3 of this 5-step model. The purpose of this commentary is to provide a perspective to assist clinicians in formulating foreground questions, searching for the best available evidence, and determining validity of results in studies of interventions for orthopaedic and sports physical therapy.
循证实践（EBP）过程指导临床医生整合个人临床专业知识、患者价值观和期望以及最佳可得证据。精通此过程需要时间和持续实践，但最终应能改善患者预后。循证实践过程包括5个步骤：（1）提出恰当的问题，（2）进行高效的文献检索，（3）严格评价最佳可得证据，（4）将最佳证据应用于临床实践，以及（5）评估护理结果。这个分为两部分的系列中的第一篇评论将回顾与这个5步模型的第1、2和3步相关的原则。这篇评论的目的是提供一个视角，以协助临床医生提出前景问题、寻找最佳可得证据以及确定骨科和运动物理治疗干预研究结果的有效性。
