The effect of posture on ventilatory muscle function and lung function
The purpose of this study was to determine the influence of posture on ventilatory muscle strength and on lung function.Maximum static inspiratory pressures (MIPS), maximum static expiratory pressures (MEPS) and lung function measurements (FVC, FEV1, PEFR) were obtained in three different body positions in 57 normal subjects and in 16 asthmatic nge
