Materials and Methods
This study consisted of two separate experiments. In the first experiment, the test-retest reliability and repeatability of the MST was assessed by comparing performance on two consecutive MST tests in a group of adult patients with stable CF disease. In the second study, the responsiveness of the MST was determined by assessing the ability of the MST to detect changes in exercise capacity after a course of IV antibiotic treatment for an acute exacerbation of respiratory disease. The study was
Assessment of Test-Retest Reliability of the MST
Table 1 shows the descriptive statistics for the physical characteristics and baseline measurements on each study day. A diversity of patients in terms of age (range, 15 to 69 years) and FEV1 (range, 14 to 72% predicted) were included in this study, demonstrating that the patients exhibited a wide range of disease impairment. There was no significant difference in FEV1, resting Sao2 and heart rate, or resting Borg rating of perceived breathlessness between the two study days (Table 1). This
Discussion
This study shows that the MST is a highly reproducible, repeatable, and responsive measure of exercise capacity in an adult CF population. The reproducibility of the SWT has been previously assessed in COPD and in cardiac populations.9, 14 The original authors of the test found that a practice test was necessary to ensure reliable results in COPD patients.9 This finding has important implications regarding the clinical utility of the SWT as a routine measure of exercise capacity because

Test-retest reliability, minimal detectable change and minimal clinically important differences in modified shuttle walk test in children and adolescents with cystic fibrosis
2020, Journal of Cystic FibrosisCitation Excerpt :We therefore suggest the modified version of the 10-m shuttle walk test (MSWT) by adding three levels and allowing patients to run, thus allowing them to reach maximum exercise capacity. Studies have shown that MSWT is reliable and valid for assessing exercise tolerance in adults with CF [9,10] and is better at detecting oxygen desaturation and carbon dioxide retention than CPET in this population [11]. For younger patients with CF, MSWT has been shown to be useful in determining clinical improvement after hospitalization [12].
