Abstract

Thoracic kyphosis is the result in restrictive and obstructive ventilation which lead to dyspnea and exercise intolerance and may cause of decreased activity of daily living in the elderly. The aim of this study was to evaluate thoracic kyphosis measured by flexicurve in relation to pulmonary function in elderly. Sixty-six elderly participants aged 6 5 years and older were recruited into the study. Interested participants were all received basic health screening and underwent thoracic kyphosis measurements using flexicurve method. All subjects who were met criteria participated in this study that were taken 3 testing: lung function tests by using spirometer, respiratory muscle strength by using maximal voluntary respiratory pressures and 6-Minute Walk Test. Pearson’s correlation coefficient was used to analyze the relationships between variables. Results showed that thoracic kyphosis was mild positive correlated with lung functions in FEV1, FVC and VC parameters (r=0.303, 0.265 and 0.322, respectively, p<0.05) but not with FEV1/FVC ratio (%) (p>0.05). There was no correlation between thoracic kyphosis and respiratory muscle strength (MIP and MEP), and also 6-minute walk distance (p>0.05). These results suggested that thoracic kyphosis as measured by the flexicurve method had mild positive correlation with lung functions. This method may provide a trend to predict lung function associated with thoracic kyphosis. Further study is warranty.
