Mobilidade diafragmática direita e esquerda em indivíduos saudáveis e na doença pulmonar obstrutiva crônica

Avaliar o músculo diafragma é importante para verificar suas possíveis alterações ou disfunções. Existem várias formas de avaliar a mobilidade diafragmática, mas poucos estudos que comparam a mobilidade do hemidiafragma direito com o esquerdo. O objetivo deste estudo é avaliar se existem diferenças entre a mobilidade diafragmática das hemicúpulas direita e esquerda em indivíduos saudáveis e em indivíduos com Doença Pulmonar Obstrutiva Crônica (DOCP), bem como comparar a mobilidade diafragmática entre homens e mulheres, e entre pacientes saudáveis e com DPOC. Foram avaliados 40 indivíduos saudáveis e 40 indivíduos com diagnóstico clínico de DPOC. Utilizaram-se os parâmetros antropométricos, cardiopulmonares e avaliação da mobilidade diafragmática pelo método radiográfico. Os dados foram analisados estatisticamente e tratados com análise descritiva (média e desvio-padrão) e análise inferencial. Para comparar a mobilidade das hemicúpulas diafragmáticas direita e esquerda, utilizou-se o teste t pareado. O nível de significância adotado para o tratamento estatístico foi de 5% (pTo evaluate the diaphragm muscle is important for verifying its possible changes or malfunctions.

Comparison of diaphragmatic mobility between COPD patients with and without thoracic hyperkyphosis: a cross-sectional study

ABSTRACT Objective: To compare diaphragmatic mobility, lung function, and respiratory muscle strength between COPD patients with and without thoracic hyperkyphosis; to determine the relationship of thoracic kyphosis angle with diaphragmatic mobility, lung function, and respiratory muscle strength in COPD patients; and to compare diaphragmatic mobility and thoracic kyphosis between male and female patients with COPD. Methods: Participants underwent anthropometry, spirometry, thoracic kyphosis measurement, and evaluation of diaphragmatic mobility. Results: A total of 34 patients with COPD participated in the study. Diaphragmatic mobility was significantly lower in the group of COPD patients with thoracic hyperkyphosis than in that of those without it (p = 0.002). There were no statistically significant differences between the two groups of COPD patients regarding lung function or respiratory muscle strength variables. There was a significant negative correlation between thoracic kyphosis angle and diaphragmatic mobility (r = −0.47; p = 0.005). In the sample as a whole, there were statistically significant differences between males and females regarding body weight (p = 0.011), height (p < 0.001), and thoracic kyphosis angle (p = 0.036); however, there were no significant differences in diaphragmatic mobility between males and females (p = 0.210). Conclusions: Diaphragmatic mobility is lower in COPD patients with thoracic hyperkyphosis than in those without it. There is a negative correlation between thoracic kyphosis angle and diaphragmatic mobility. In comparison with male patients with COPD, female patients with COPD have a significantly increased thoracic kyphosis angle

Validity and reliability of fluoroscopy for digital radiography: a new way to evaluate diaphragmatic mobility

Abstract Background Fluoroscopy is considered the most accurate method to evaluate the diaphragm, yet most existing methods for measuring diaphragmatic mobility using fluoroscopy are complex. To assess the validity and reliability of a new evaluation method of diaphragmatic motion using fluoroscopy by digital radiography of healthy adults. Methods Twenty-six adults were evaluated, according to the parameters: anthropometry and pulmonary function test. The evaluation of diaphragm mobility by means of fluoroscopy by digital radiography method was randomly conducted by two raters (A and B). The Pearson correlation coefficient and the intraclass correlation coefficient (ICC) were used to assess the concurrent validity. The inter-rater and intra-rater reliability of the measurement of diaphragmatic motion was determined using ICC and a confidence interval of 95%. Results There was a relationship in the assessment of the concurrent validity. There was good inter-rater reliability for right hemidiaphragm mobility and moderate reliability for left hemidiaphragm in the first assessment. In the second assessment, there was good reliability for the mobility of both hemidiaphragms. There was good intra-rater reliability in the mobility of both hemidiaphragms for raters A and B. Conclusion The evaluation of diaphragmatic motion using fluoroscopy by digital radiography proved to be a valid and reliable method of healthy adults

Mobility of right and left hemidiaphragms in healthy individuals and in individuals with chronic obstructive pulmonary disease

<p></p><p>ABSTRACT To evaluate the diaphragm muscle is important for verifying its possible changes or malfunctions. There are several ways to evaluate the diaphragmatic mobility, but only a few compare the mobility of the right hemidiaphragm with the left one. The aim of this study was to evaluate whether there are differences between the mobility of right and left hemidiaphragms in healthy individuals and individuals with chronic obstructive pulmonary disease (COPD), as well as to evaluate the diaphragmatic mobility between men and women, and between healthy and COPD patients. We evaluated 40 healthy individuals and 40 individuals with clinical diagnosis of COPD. Anthropometric and cardiopulmonary parameters were used. The diaphragmatic mobility was evaluated by radiography. Data were statistically analyzed and processed with descriptive analysis (mean and standard deviation) and inferential analysis. To compare the mobilities of the right and left hemidiaphragms, the paired t-test was used. The significance level adopted for statistical treatment was 5% (p<0.05). There was no difference of the diaphragmatic mobility for both left and right sides in healthy individuals (p=0.45) and individuals with COPD (p=0.77). Also, no differences were found when groups were separated according to sex. An important difference was found comparing both diaphragmatic mobilities of the right and left sides between healthy and COPD individuals (p<0.001). We concluded that mobility of left and right hemidiaphragms in healthy and COPD individuals is the same. There is no difference for mobility between men and women. Diaphragmatic mobility is reduced in COPD patients.</p><p></p
