Abstract
Background: Patients with idiopathic pulmonary fibrosis (IPF) often experience a decline in activities of daily living (ADL) due to progressive lung impairment. Therefore, it is essential to evaluate ADL performance in a way that reflects real-life challenges.
Purpose: This study aims to investigate the metric properties of the Londrina ADL Protocol in patients with IPF.
Methods: Thirty-three patients (66.7% men, age: 66.7 ± 5.2 years) participated in this observational metric analysis study. We evaluated the protocol's validity, reliability, standard error of measurement (SEM), and minimal detectable change with 95% confidence (MDC95). To assess validity, we calculated correlation coefficients between the Londrina-ADL protocol and the Glittre Test (TGlittre), the 6-Minute Walk Test (6MWT), the London Chest-ADL (LCADL) Scale, hand grip strength, knee extension strength, and respiratory functions. Intra-rater reliability was analyzed using the intraclass correlation coefficient (ICC), paired sample t-test, SEM, MDC95, and the learning effect.
Results: The Londrina-ADL protocol showed significant correlations with the TGlittre, the 6MWT, the LCADL, hand grip strength, knee extension strength, and respiratory functions (r = 0.742, r = -0.619, r = 0.665, r = -0.601, r = -0.587, p < .001, respectively.). The protocol demonstrated excellent intra-rater reliability (ICC = 0.939). Test durations differed significantly between tests (p < .001). The SEM and MDC95 values were 8.69 seconds and 24.01 seconds, respectively, with a learning effect of 4.7% observed between the first and second tests.
Conclusion: Given its strong metric properties, the Londrina-ADL protocol may serve as a practical and sensitive tool for evaluating daily functional capacity and guiding individualized rehabilitation strategies in patients with IPF.
背景：特发性肺纤维化（IPF）患者通常由于进行性肺损伤而导致日常生活活动（ADL）下降。因此，必须以反映现实挑战的方式评估ADL的性能。目的：本研究旨在探讨Londrina ADL方案在IPF患者中的度量特性。方法：33例患者（男性66.7%，年龄：66.7±5.2岁）参与观察性计量分析研究。我们评估了方案的有效性、可靠性、测量标准误差（SEM）和95%置信度的最小可检测变化（MDC95）。为了评估有效性，我们计算了Londrina-ADL方案与Glittre测试（TGlittre）、6分钟步行测试（6MWT）、London Chest-ADL （LCADL）量表、手部握力、膝关节伸展力和呼吸功能之间的相关系数。采用类内相关系数（ICC）、配对样本t检验、扫描电镜（SEM）、MDC95和学习效应分析了组内信度。结果：Londrina-ADL方案与TGlittre、6MWT、LCADL、手掌握力、膝关节伸展力、呼吸功能有显著相关性（r = 0.742, r = -0.619, r = 0.665, r = -0.601, r = -0.587, p < 0.001）。该方案具有良好的内部可靠性（ICC = 0.939）。测试持续时间在测试之间差异显著（p 95值分别为8.69秒和24.01秒），在第一次和第二次测试之间观察到4.7%的学习效果。结论：鉴于其强大的度量特性，Londrina-ADL方案可作为评估IPF患者日常功能能力和指导个性化康复策略的实用且敏感的工具。
期刊介绍：
The aim of Physiotherapy Theory and Practice is to provide an international, peer-reviewed forum for the publication, dissemination, and discussion of recent developments and current research in physiotherapy/physical therapy. The journal accepts original quantitative and qualitative research reports, theoretical papers, systematic literature reviews, clinical case reports, and technical clinical notes. Physiotherapy Theory and Practice; promotes post-basic education through reports, reviews, and updates on all aspects of physiotherapy and specialties relating to clinical physiotherapy.
