摘要

研究目的本研究旨在验证基于单次重复最大吸气压力测试原理的最大吸气压力测试方案,评估其重测可靠性,并确定慢性阻塞性肺病(COPD)患者的最小可检测变化:方法:49 名慢性阻塞性肺病患者参加了研究,其中 44 人参加了两次预约,每次间隔 7 至 10 天,以确保测试的重复可靠性。最大吸气压力测试使用阈值阀装置(基于一次重复最大值的方案)和数字压力计(参考测试)进行。基于一次重复最大值的方案包括一个递增阶段(吸气负荷增加[10 cmH2O]以达到呼吸衰竭)和一个接近阶段(规定最低失败尝试和最后有效尝试之间一半的负荷):基于最大吸气压力测试的一次重复最大值方案与参考测试的并发有效性良好(第 1 天,ICC = 0.81;第 2 天,ICC = 0.85)。测试重复可靠性极佳(ICC = 0.92),测量标准误差为 6.3 cmH2O,最小可检测变化为 17.5 cmH2O:这项研究验证了使用吸气肌肉训练装置对慢性阻塞性肺病患者进行最大吸气压力测试的新方案,与参考测试相比,该方案显示出良好的并发效度和极佳的测试重复可靠性。所报告的最小可检测变化可在临床环境中解释和应用:影响:有必要为最大吸气压力测试开发新的、廉价的、简单可行的方法。基于最大吸气压力的单次重复方案的验证解决了这一问题,可为吸气肌肉训练开出适当的处方,有利于其在慢性阻塞性肺病患者中的广泛应用,从而改善物理治疗师的护理。

New Protocol for Evaluating Maximum Inspiratory Pressure: Concurrent Validity and Test-Retest Reliability.

Objective: The purpose of this study was to validate a maximum inspiratory pressure test protocol based on the principles of the one-repetition maximum test, assess its test-retest reliability, and establish minimal detectable change in individuals with chronic obstructive pulmonary disease (COPD).

Methods: Forty-nine individuals with COPD were included in the study, of whom 44 individuals attended 2 appointments separated by 7 to 10 days for test-retest reliability. The maximum inspiratory pressure test was performed using a threshold valve device (one-repetition maximum-based protocol) and the digital manometer (reference test). The one-repetition maximum-based protocol consisted of an incremental phase (inspiratory load increase [10 cmH2O] to achieve respiratory failure) and an approach phase (load halfway between the lowest failed attempt and the last valid attempt was prescribed).

Results: The concurrent validity of the one-repetition maximum-based protocol for the maximum inspiratory pressure test was good with respect to the reference test (day 1, ICC = 0.81; day 2, ICC = 0.85). The test-retest reliability was excellent (ICC = 0.92), with a standard error of measurement of 6.3 cmH2O and a minimal detectable change of 17.5 cmH2O.

Conclusion: This study validated a new one-repetition maximum-based protocol for the maximum inspiratory pressure test using an inspiratory muscle training device in individuals with COPD, showing good concurrent validity compared with the reference test, as well as excellent test-retest reliability. The minimal detectable change reported can be interpreted and applied in the clinical setting.

Impact: There was a need for developing new, inexpensive, simple, and feasible methods for the maximum inspiratory pressure test. The validation of the one-repetition maximum-based protocol addresses this issue, allowing for the appropriate prescription of inspiratory muscle training, favoring its widespread use in people with COPD and therefore improving their physical therapist care.
