Detailed pulmonary function tests were performed on 12 patients with cystic fibrosis (CF) before and after 3 days treatment with postural drainage incorporating the forced expiration technique. The results following treatment showed a statistically significant improvement in FEV1 (P less than 0.001), FVC (P less than 0.001), PEFR(P less than 0.001), PIFR (P less than 0.001), and VEmax50 (P less than 0.025). The study demonstrates objective benefit from this form of physiotherapy in cystic fibrosis patients with copious bronchial secretions.
对12例囊性纤维化（CF）患者在采用强制呼气技术进行体位引流治疗3天前后进行了详细的肺功能测试。治疗后的结果显示，第一秒用力呼气容积（FEV1，P<0.001）、用力肺活量（FVC，P<0.001）、呼气峰流速（PEFR，P<0.001）、吸气峰流速（PIFR，P<0.001）和最大中期呼气流速（VEmax50，P<0.025）均有统计学意义的改善。该研究证明了这种物理治疗方式对支气管分泌物大量的囊性纤维化患者具有客观益处。
