Elaine Paulin

Objective: There is little scientific evidence on the effects of breathing exercises (BE) on chest wall (CW) movement. The aim of this study was determine and compare the influence of diaphragmatic breathing (DB), fractionated breaths (FB), sniff inspiration (SI) and breathing from functional residual capacity (BFRC) on thoracoabdominal wall volumes in healthy adults in the sitting position and in dorsal decubitus at 30° trunk inclination. Methods: Chest wall volumes (Vcw) were assessing by optoelectronic plethysmography (OEP) were assessed in the sitting position and 30° trunk inclination.
