Comparison of the modified shuttle walk test in children with cystic fibrosis and healthy controls.

Objective: To evaluate and compare performance in the modified shuttle walk test (MSWT) with cardiorespiratory parameters and respiratory muscle strength in children with cystic fibrosis (CF) and healthy controls.

Methods: A cross-sectional study with children divided into the CF group (CFG) and healthy control group (HCG). Two MSWTs were performed and the data from the test with the longest distance walked and its cardiorespiratory parameters (blood pressure, respiratory rate, heart rate (HR), oxygen saturation, and dyspnea sensation) were considered, the last three every 4 levels.

Impact of Forced Exhalation Maneuvers During Spirometry on Airway Resistance Measured by Oscillometry in Healthy Children.

Objective: To analyze the impact of repeated forced spirometry maneuvers on oscillometry parameters of healthy children.

Methods: This is a cross-sectional study with healthy children (6-12 y old) from schools in Florianopolis-SC/Brazil. Good health condition was confirmed through questionnaires, health history, and normal spirometry.

Coughing and diaphragmatic breathing exercise: What is the repercussion on respiratory mechanics of children and adolescents with cystic fibrosis?

Introduction: The aim of this study was to investigate the immediate effect of coughing episodes and diaphragmatic breathing exercise (DBE) on respiratory mechanics of children/adolescents with cystic fibrosis (CF).

Methods: It is a cross-sectional analytical study that occurred in a reference center for children with CF. Forty-five children/adolescents with CF (60% male; mean age 10.

Pediatric Glittre ADL-test in cystic fibrosis: Physiological parameters and respiratory mechanics.

: To evaluate the functional capacity in children and adolescents with cystic fibrosis (CF) through the pediatric Glittre ADL-test (TGlittre-P) and its implications for respiratory mechanics, physiological parameters and clinical markers. : Impulse oscillometry system (IOS) parameters, vital signs (heart rate, respiratory rate and blood pressure), perception of dyspnea and peripheral oxygen saturation (SpO) were assessed before and immediately after the TGlittre-P. Test performance was correlated with age, quality of life, disease severity, nutrition, spirometry and IOS parameters.
