Three months of IWPS improved the lung function, such as force expiratory volume (FEV1) (p < 0.048), forced expiratory volume in the first second/forced vital capacity ratio (FEV1/FVC) (forced vital capacity) (p < 0.003), forced expiratory volume 25-75% (FEF25-75%) (p < 0.048), and peak expiratory flow (PEF) (p < 0.002).
