Voice problems have been reported in chronic cough (CC) and paradoxical vocal fold movement (PVFM), however, there is a lack of a systematic description of voice characteristics in these conditions. This study examined the perceptual voice characteristics of 56 individuals with CC, 8 with PVFM and 55 with both CC and PVFM, compared to 25 people with muscle tension dysphonia (MTD) and 27 healthy controls. There was a high prevalence of abnormal voice quality in the CC and PVFM groups compared with healthy controls. More than one third of participants with CC and PVFM demonstrated strained, rough and/or breathy voices to a moderate or severe degree. The perceptual features in CC and PVFM were similar to those in MTD with greater severity evident in MTD. Possible mechanisms for abnormalities in voice quality include the presence of muscle tension and the frequency of coughing. These results have implications for the identification and management of voice disorders in CC and PVFM and suggest that clinicians should be alert to the incidence of voice abnormalities in these populations.
据报道，慢性咳嗽（CC）和反常性声带运动障碍（PVFM）患者存在嗓音问题，然而，目前缺乏对这些情况下嗓音特征的系统描述。本研究检查了56名慢性咳嗽患者、8名反常性声带运动障碍患者和55名同时患有慢性咳嗽和反常性声带运动障碍的患者的嗓音感知特征，并与25名肌肉紧张性发声障碍（MTD）患者和27名健康对照者进行了比较。与健康对照者相比，慢性咳嗽组和反常性声带运动障碍组中嗓音质量异常的发生率较高。超过三分之一的慢性咳嗽和反常性声带运动障碍参与者表现出中度或重度的紧张、粗糙和/或呼吸音。慢性咳嗽和反常性声带运动障碍的感知特征与肌肉紧张性发声障碍相似，肌肉紧张性发声障碍更为严重。嗓音质量异常的可能机制包括肌肉紧张的存在和咳嗽频率。这些结果对慢性咳嗽和反常性声带运动障碍患者嗓音障碍的识别和管理具有启示意义，并表明临床医生应警惕这些人群中嗓音异常的发生率。
