Comparison of Cardiopulmonary Responses During 2 Incremental Step Tests in Subjects With COPD

“…In moderate to severe COPD, this test was reproducible for step number (ICC = 0.99) and physiological parameters (ICCs [ 0.93) [55], although a learning effect was demonstrated. However, VO 2 peak was higher in MIST compared to the CST in COPD [72].…”

“…The MIST is similar to the CST, but with a slower initial step rate (10 steps/min) and incremental size (2 steps/min), with the same criteria for test cessation [55,72], with the addition of an inability to maintain the pace for 15 s [72]. In moderate to severe COPD, this test was reproducible for step number (ICC = 0.99) and physiological parameters (ICCs [ 0.93) [55], although a learning effect was demonstrated.…”

Assessment of exercise capacity and physical function is critical in individuals with respiratory conditions. While field walking tests are well-established measures of exercise capacity, alternative options involving walking of a shorter duration, stair or step climbing, and functional activities are also available. This review outlines these alternative tests and their relevant measurement properties, including comparisons with established field walking tests and their clinical applications. The 4-m gait speed and 30-m walking test are walking tests of shorter duration than traditional tests and may be a surrogate marker for exercise capacity. Stair climbing tests require greater body movement against gravity, often imposing a greater workload compared to field walking tests. Functional tests such as sit-to-stand tests provide information related to strength and general functioning. The current measurement properties established, together with the emerging evidence for responsiveness to interventions suggest potential for broader clinical use of these alternative field tests.

“…Workload (watts) was estimated based on the following formula: step height (m) × number of cycles × weight (kg) × 0.16357. 9 This study was approved by the Ethics Committee of Universidad San Sebastián; each participant's legal guardian was asked to sign an informed consent. The study was conducted between September and December 2014.…”

The objective of this study was to determine the validity and reliability of the EPInfant pediatric perceived exertion rating scale among Chilean children. Children aged 8-12 years old were selected; their heart rate, perceived exertion and workload were recorded during two consecutive Chester tests performed with a one week interval. Pearson's r coefficient and the intraclass correlation coefficient were estimated. Thirty-one children (17 boys) were included in the study. A strong correlation was observed between perceived exertion and reference criteria, in addition to a high intraclass correlation coefficient. The average difference between the perceived exertion in each test was 1.4 (95% CI: -1.4 to 4.1) and 0.2 (95% CI: -1.8 to 2.2) for boys and girls, respectively. The EPInfant scale showed an acceptable criterion validity and interobserver reliability among children during an incremental step test.

Comparison of Cardiopulmonary Responses During 2 Incremental Step Tests in Subjects With COPD

Abstract: The slower the work rate increment during step test, the higher the exercise tolerance. Regardless of the work rate increment, cardiopulmonary stress and exertion effort at peak exercise were equivalent between tests.
