“…The reliability of the different step tests has been studied among patients with idiopathic pulmonary fibrosis 23 , COPD 16 , asthma 24 , or cystic fibrosis 25 . Although Swinburn et al 26 observed great variation between the four step tests conducted on patients with COPD, most studies have found the opposite (i.e., little variation between the step tests among patients with chronic lung disease 16,[23][24][25] ). In patients with COPD, the CST was highly reliable for tests conducted on the same day 16 , with an ICC of 0.99 (95% CIs=0.97 to 0.99) for NOSs.…”

“…Step Test (CST), which was designed to estimate aerobic capacity in healthy participants [11][12][13] , has also been used among patients with pulmonary disease [14][15][16] . However, the CST is a strenuous protocol because fewer than half of patients in recovery from severe acute respiratory syndrome are able to complete the test 14 .…”

“…However, the CST is a strenuous protocol because fewer than half of patients in recovery from severe acute respiratory syndrome are able to complete the test 14 . Furthermore, only 22% of patients with chronic obstructive pulmonary disease (COPD) are able to complete up to three of the five stages of the CST 16 . In light of these data, our group adapted the CST to reduce the initial rate to 10 steps/min and introduce increments of up to a step every 30 seconds throughout the test 17 .…”

| Background: The step test has been used to assess exercise capacity in patients with chronic respiratory disease; however, its use has not been described with regard to patients with bronchiectasis (BCT). Objective: This study assessed the reliability of the Chester step test (CST) and the modified incremental step test (MIST) and also correlated these tests with pulmonary function, heart rate (HR), and distance walked during the 6-min walk test (6-MWT). Method: On separate days, 17 patients randomly underwent two CSTs, two MISTs, and two 6-MWTs. Number of steps (NOSs), HR, and perceived exertion were recorded immediately before and after these tests. Results: NOSs were similar across CSTs (124±65 and 125±67) and MISTs (158±83 and 156±76). Differences were not found across the CSTs and MISTs with regard to HR (138±25 bpm and 136±27 bpm), SpO 2 (91±5% and 91±3%), perceived exertion (dyspnea=4

“…Por otra parte, las cargas de trabajo desarrolladas durante la prueba fueron significativamente distintas entre sujetos del mismo sexo y distinta edad (cuadro 2), lo cual responde a que el cálculo de la carga (Watts) durante la prueba se hizo en función de la estatura y el peso (21). En la muestra estudiada, los sujetos del grupo de 13 a 15 años tenían mayor estatura y peso que los del grupo de 8 a 12 años.…”

Introducción. Las escalas de esfuerzo percibido cuantifican la sensación causada por los cambios metabólicos durante el ejercicio. Debido a su inmadurez cognitiva, los niños necesitan instrumentos adaptados, motivo por el cual se desarrolló la escala de medición de esfuerzo percibido infantil, EPInfant. Objetivo. Determinar la validez y confiabilidad de la escala EPInfant durante una prueba de ejercicio de intensidad gradualmente creciente. Materiales y métodos. Se hizo un estudio de corte transversal. Se seleccionaron niños de dos grupos de edad por categoría de desarrollo cognitivo: de 8 a 12 años (operaciones concretas) y de 13 a 15 años (inteligencia formal). Todos respondieron el test de Chester y se registraron su frecuencia cardiaca, la carga de trabajo y el esfuerzo percibido durante la prueba. Los coeficientes r de Pearson y de correlación intraclase se emplearon para determinar la validez y la confiabilidad. Resultados. De 75 niños participantes, 35 (18 hombres) se clasificaron en el grupo de operaciones concretas y 40 (20 hombres) en el de inteligencia formal. En los cuatro grupos la frecuencia cardiaca y el esfuerzo percibido se incrementaron durante la prueba (p<0,0001). El esfuerzo percibido se correlacionó con la frecuencia cardiaca en los grupos de operaciones concretas e inteligencia formal en hombres y mujeres: r=0,73, r=0,58, r=0,43 y r=0,62, respectivamente (p<0,0001). Los modelos de regresión fueron significativos en los cuatro grupos. En el subgrupo perteneciente a la etapa de operaciones concretas, el coeficiente de correlación intraclase fue de 0,88 (0,82-0,92) en hombres y de 0,94 (0,91-0,96) en mujeres. Conclusión. La escala EPInfant resultó válida para medir el esfuerzo percibido durante el ejercicio en niños y niñas con distintos niveles de madurez cognitiva, y fue confiable en los niños del grupo de operaciones concretas.Palabras clave: reproducibilidad de resultados, validez de las pruebas, estudios de validación como asunto, tolerancia al ejercicio, esfuerzo físico, cognición, niño, adolescente. doi: http://dx.doi.org/10.7705/biomedica.v36i1.2720 Initial validation of the scale of perceived exertion (EPInfant) in Chilean childrenIntroduction: Perceived exertion scales quantify the sensation caused by metabolic changes during exercise. Children need tailored tools due to their cognitive immaturity such as the EPInfant scale recently developed in Chile. Objective: To determine the validity and reliability of the EPInfant scale in children during a graded exercise test. Materials and methods: We conducted a cross-sectional study for which we selected healthy children younger than 18 years and grouped them according to Piaget's stages of cognitive maturity: Concrete operations (8-12 years) and formal intelligence (13-15 years). The Chester step test was used and heart rate, workload and perceived exertion were recorded during the test. Pearson r and intraclass correlation coefficients were used to assess validity and reliability, respectively. Results: 75 children were admitted, 35 (18...

Alternative field exercise tests for people with respiratory conditions

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.
