What about blinding makes it so important that it becomes a stamp of superiority on a clinical trial? Blinding isn't a part of clinical practice, as it plays no role in day-to-day treatment of patients. So why should it concern us so much when it comes to research? Blinding is one of those issues that is more complex than at first glance, and even more so in the context of the sorts of trials relevant to physical therapists. Trials in which participants, therapists, and/or assessors are not blinded are at risk of bias, but that is not the end of the story. The magnitude of the risk also depends on the types of interventions and the nature of the outcomes. J Orthop Sports Phys Ther 2018;48(10):825-826. doi:10.2519/jospt.2018.0705.
为什么盲法如此重要,以至于它成为临床试验的一个优越标志?盲法不是临床实践的一部分,因为它在日常治疗患者中没有作用。那么,当涉及到研究时,为什么它会让我们如此关注呢?盲法是一个比乍看起来更复杂的问题,在与物理治疗师相关的试验中更是如此。参与者、治疗师和/或评估者没有被盲法的试验存在偏倚的风险,但这并不是故事的结局。风险的大小也取决于干预措施的类型和结果的性质。J Orthop Sports Phys Ther 2018;48(10):825-826. doi:10.2519/jospt.2018.0705.
