Abstract

Valores de referência e fatores relacionados à mobilidade torácica em crianças brasileirasValores de referencia y factores relacionados con la movilidad torácica en niños brasileños Raphaella Oliveira E. da ABSTRACTObjective: To provide reference values and to evaluate the factors influencing thoracic mobility in children aged 7 to 11 years old.Methods: A total of 166 children were assessed from public and private schools (90 girls and 76 boys) in the city of Natal (Northeast Brazil). Demographic and anthropometric data were collected, and the thoracic perimeter was assessed by cirtometry. Non-paired Student's t-test and variance analysis compared xiphoid respiratory coefficient between sex and ages, respectively. Axillary respiratory coefficient differences between sex and ages were tested by Mann-Whitney and Kruskal-Wallis tests, respectively, with differences located by Duncan post-hoc test. Spearman and Pearson correlation coefficients were used to verify the association between independent variables with the assessed coefficients.Results: Xiphoid and axillary perimetry means were 5.00±1.59 and 4.75±1.56cm, respectively. There was a low correlation, without statistical significance, between xiphoid respiratory coefficient and age, sex, weight, height, and body mass index. The axillary respiratory coefficient was correlated with weight and height. Differences were found in the axillary respiratory coefficient in the age groups between 8-10 (p=0.03) and 10-11 years old (p=0.02).Conclusions: Reference values for thoracic cirtometry were provided for children aged between seven and 11 years old. Sex, age, weight, height, and body mass index did not influence xiphoid respiratory coefficient. The axillary respiratory coefficient was different between ages, from eight years onwards, being significantly influenced by height and weight regardless of sex.

“…According to the study, "Thoracic mobility is related to the integrity of the respiratory muscles, which assists in the expansion and retraction of the thoracic cavity. " 20 This measure is used to "assess parameters such as thoracic amplitude, lung volumes and capacities, lung compliance, thoracoabdominal mechanics, diaphragmatic function, muscle work and dyspnea. " 20 "Chest mobility and lung function may change not only with the growth and appearance of respiratory diseases, but also with other factors such as body composition, sex, age, height, and ethnicity.…”

Impacto do tipo de parto sobre a mobilidade Toracoabdominal de recém-nascidos

“…Often, this respiratory discomfort is evaluated through the number of respiratory incursions and the quality of thoracic expandability, the lower the thoracoabdominal mobility and the greater the respiratory rate, the worse the clinical condition of the newborn 5,7 . However, in clinical practice, noninvasive methods capable of quantifying respiratory evolution are preferable and also more reliable when compared to the subjective evaluation of the quality of thoracic expandability [8][9][10] . Considering that cesarean delivery can be a difficult factor in the respiratory evolution of newborns and that thoracoabdominal mobility is directly related to the clinical condition of the newborn, the present study aims to evaluate the impact of the type of delivery on the thoracic and abdominal mobility in newborns (NBs).…”

“…The use of photogrammetry for the analysis of respiratory movement allows establishing evidence related to thoracic and abdominal kinetics, this information can be used to infer respiratory mechanical behavior even in patients who do not voluntarily control respiration, as in newborns [8][9][10][11][12] . However, some limitations should be considered.…”
