Summary

Asthma is a chronic respiratory disease that can negatively affect exercise tolerance and functional capacity due to airway inflammation, variable airflow limitation, and symptom-related activity avoidance. Reduced physical activity levels and exercise-induced symptoms often lead to physical deconditioning, which may further impair cardiorespiratory fitness and daily functional performance in individuals with asthma. There is substantial evidence supporting the use of cardiopulmonary exercise testing (CPET) for the evaluation of exercise capacity in patients with respiratory diseases. However, it is not known whether the use of the 6-minute stepper test (6-MST) is a valid and reliable test for the assessment of functional exercise capacity in patients with asthma. The aim of this study is to investigate the reliability and validity of the 6-MST for evaluating functional exercise capacity in individuals with asthma.

Detailed description

Asthma is a chronic inflammatory disorder of the airways, characterized by variable airflow obstruction, bronchial hyperresponsiveness, and respiratory symptoms including wheezing, dyspnea, and chest tightness. Although pharmacological treatment remains the cornerstone of asthma management, the evaluation of functional capacity and exercise tolerance has become increasingly important, particularly in individuals with moderate to severe asthma.Cardiopulmonary exercise testing (CPET) is regarded as the gold standard for the comprehensive assessment of cardiovascular, ventilatory, and musculoskeletal system performance through a multidimensional approach. It provides detailed measurements of oxygen uptake (VO₂), carbon dioxide production (VCO₂), ventilatory thresholds, heart rate responses, and subjective symptoms such as dyspnea and fatigue related to musculoskeletal performance. Nevertheless, CPET requires specialized equipment and trained personnel and may not be feasible in all clinical settings, particularly for routine follow-up or in environments with limited technical resources. In contrast, the 6-minute stepper test (6-MST) has gained attention as a practical, low-cost alternative that requires minimal equipment for the assessment of functional capacity. The 6-MST consists of stepping up and down on a fixed-height platform for six minutes, with the total number of steps used as an indicator of endurance. Owing to its minimal space and equipment requirements, the test is well suited for outpatient settings, home-based rehabilitation programs, and telerehabilitation applications. However, it is not known whether the 6 MST is valid and reliable in assessing functional exercise capacity in patients with asthma. Therefore, the aim is to examine the validity and reliability of the 6 MST in patients with asthma. The study was planned as a retrospective study. All patients' clinical data, maximal exercise capacity, functional exercise capacity pulmonary function, dyspnea, and quality of life were assessed.The results will be analysed and interpreted using appropriate statistical analysis methods.
