We read with interest the publication by Crook et al. [1] on the validation and responsive properties of the 1-min sit-to-stand (STS) test in patients with chronic obstructive pulmonary disease (COPD) undergoing pulmonary rehabilitation. The authors performed a comprehensive evaluation of the minimal clinical meaningful difference of the 1-min STS test. In our own dataset of patients from a multicentre study, this STS test exhibited similar level of reliability, intra-subject repeatability [2], and responsiveness to pulmonary rehabilitation with an estimated minimal important difference (MID) of three repetitions [3]. In their study, Crook et al. [1] emphasised the change in STS repetitions, which is better related to change in subjective outcomes (feeling thermometer notably), rather than with physical capacity outcomes such as the 6-min walk distance (6MWD). It is, after all, largely accepted that health-related quality of life (HRQoL) tools are the most sensitive in pulmonary rehabilitation, given the multimodal and patient-tailored interventions addressed in order to optimise benefits, not only focused on exercise training, but also on change in education and behaviour [4]. The change in the sit-to-stand test after a pulmonary rehabilitation is not influenced by the initial value http://ow.ly/i2CI30eqprD

COPD患者坐立试验的验证

我们饶有兴趣地阅读了 Crook 等人的出版物。[1] 关于在接受肺康复治疗的慢性阻塞性肺疾病 (COPD) 患者中进行 1 分钟坐立 (STS) 测试的验证和响应特性。作者对 1 分钟 STS 测试的最小临床意义差异进行了综合评估。在我们自己的多中心研究患者数据集中，该 STS 测试表现出相似水平的可靠性、受试者内可重复性 [2] 和对肺康复的反应性，估计最小重要差异 (MID) 为 3 次重复 [3]。在他们的研究中，克鲁克等人。[1] 强调了 STS 重复次数的变化，这与主观结果的变化（尤其是感觉温度计）更好地相关，而不是物理能力结果，例如 6 分钟步行距离 (6MWD)。毕竟，人们普遍认为，健康相关生活质量 (HRQoL) 工具是肺康复中最敏感的工具，考虑到为优化益处而提出的多模式和针对患者的干预措施，不仅侧重于运动训练，而且还涉及教育和行为的改变 [4]。肺康复后坐立试验的变化不受初始值的影响 http://ow.ly/i2CI30eqprD 以及教育和行为的改变 [4]。肺康复后坐立试验的变化不受初始值的影响 http://ow.ly/i2CI30eqprD 以及教育和行为的改变 [4]。肺康复后坐立试验的变化不受初始值的影响 http://ow.ly/i2CI30eqprD
