Abstract

To examine the influence of kyphosis on pulmonary function in the elderly, 300 consecutive healthy subjects (aged 20-94 years old) were evaluated using pulmonary function tests (TLC, VC, FEV1, RV) and static maximal pressures (PImax and PEmax). Kyphosis of the thoracic bones was measured at Cobb's angle. VC, FEV1. PImax and PEmax showed a significant age-dependent decline. Cobb's angle had a positive relationship with age and was negatively correlated with TLC, VC, FEV1 and PImax. Further, RV/TLC strongly correlated with Cobb's angle and PImax. Stepwise regression analysis revealed that the kyphotic angle was an independent determinant for PImax and RV/TLC. These results indicate that kyphosis significantly affects lung volume and maximal inspiratory pressure in the elderly and those affected should have careful assessment of their pulmonary function and respiratory pressures.
