The effect of short, medium and long term physiotherapy remain controversial. The theoretical objectives of the method are to reduce dyspnoea and respiratory disability while improving exercise performance and expectation of life. As regards respiratory mechanics, the goals are to reduce bronchial obstruction and the mechanical properties of the chest wall. A rise in expiratory flow might result in an increased drainage of secretions, a reduction in transmural bronchial pressure and a raised level of ventilation at end-tidal volume. The correction of parietal distortions by physiotherapy has as an objective a diminution of thoracic elastance. Muscular training, a new aspect of respiratory physiotherapy, consists of increased both the endurance and the force of contraction of the respiratory muscles. The beneficial effects of these recent methods require confirmation with long term clinical studies. The correct indications for the diverse techniques proposed require a better understanding of the mechanism of action of respiratory physiotherapy, an essential complement to effective treatment of chronic airflow obstruction.
短期、中期和长期物理治疗的效果仍存在争议。该方法的理论目标是减轻呼吸困难和呼吸功能障碍，同时提高运动能力和预期寿命。关于呼吸力学，目标是减轻支气管阻塞和胸壁的力学特性。呼气流量的增加可能导致分泌物引流增加、跨壁支气管压力降低以及潮气末通气水平提高。通过物理治疗纠正胸壁变形的目的是降低胸廓弹性。肌肉训练是呼吸物理治疗的一个新方面，包括增强呼吸肌的耐力和收缩力。这些最新方法的有益效果需要长期临床研究来证实。对于所提出的各种技术，正确的适应症需要更好地理解呼吸物理治疗的作用机制，这是有效治疗慢性气流阻塞的重要补充。
