Table 2.
Anterior-posterior (AP) and cranio-caudal (CC) kinematic excursion measured in LOPD and CON subjects revealed that at peak inspiration, the CC height of the lung was significantly reduced in LOPD, and this reduced inspiratory height resulted in a lower CC excursion during inspiratory capacity (mean, SD).
