Vocal cord dysfunction induced by exercise in children with uncontrolled asthma was identified by laryngoscopy. The paradoxical adduction of the vocal cords was also indicated by the breathing-related changes of the forced oscillation respiratory resistance showing prominent increase during inspiration and a large positive difference between inspiration and expiration. The breathing-related changes of respiratory resistance offer thus a useful first-line technique to diagnose vocal cord dysfunction.
通过喉镜检查确定了运动诱发的未控制哮喘儿童的声带功能障碍。声带的矛盾性内收也通过强迫振荡呼吸阻力的呼吸相关变化得以体现，表现为吸气时显著增加，且吸气与呼气之间存在较大的正向差异。因此，呼吸阻力的呼吸相关变化为诊断声带功能障碍提供了一种有用的一线技术。
