“…This adductory pattern is in contrast to the normal cycle of respiration whereby the vocal folds abduct slightly during inspiration 31 and adduct slightly during expiration. 32 Excessive glottal narrowing may also be present during expiration in some people with PVFM.…”

“…32 Excessive glottal narrowing may also be present during expiration in some people with PVFM. 31 A comprehensive description of PVFM was provided by Christopher et al, 2 who reported on five cases of uncontrollable asthma. After evaluation, these people were found to have normal pulmonary function tests and no bronchial hyperreactivity.…”

“…However, during symptomatic episodes, there was a marked limitation of inspiratory flow and almost complete adduction of the true vocal folds, with the glottis narrowing to a small posterior diamond-shaped chink. Symptoms of PVFM (Table 2) 3,33-41 are usually episodic 31 and can sometimes be localized to the larynx. 31 Blager 42 hypothesized that PVFM may begin with a vulnerable respiratory system either intrinsic or acquired, combined with consequent or subsequent variations in central nervous system function (CNS).…”

“…Some authors contend that voice quality is normal between episodes of PVFM [26][27][28] , whereas Treole et al [6] found endoscopic and stroboscopic evidence of residual laryngeal muscle tension after PVFM attacks and concluded that this could contribute to altered phonatory characteristics in these patients. Specifically Treole et al [6] reported an increased prevalence of lateral ventricular constriction, decreased mucosal wave and decreased lateral amplitude in individuals with PVFM.…”

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.

“…Paradoxical vo-cal fold movement (PVFM) is a related condition whereby the vocal folds adduct episodically and involuntarily during inspiration. This phenomenon leads to reduced inspiratory airflow associated with signs of stridor and a perception of breathing discomfort characterized by the inability to inspire sufficient air [3] . Extrathoracic airway hyperresponsiveness is thought to be the primary underlying pathophysiology of PVFM [4] .…”

Objective: Chronic cough (CC) and paradoxical vocal fold movement (PVFM) may be associated with voice problems. Objective acoustic and electroglottographic (EGG) measures have the capacity to delineate these vocal characteristics. This study investigated acoustic and EGG voice features of CC and PVFM. Patients and Methods: Acoustic and EGG findings were compared among 5 groups of participants. The first 3 groups, CC (n = 56), PVFM (n = 8) and combined CC-PVFM (n = 55), included individuals with cough and respiratory symptoms that persisted despite medical treatment. Groups 4 and 5 included individuals with muscle tension dysphonia (n = 25) and healthy controls (n = 27). Results: Participants with CC/PVFM recorded reduced phonation times (p < 0.001), greater jitter (p < 0.001), reduced harmonic to noise ratio (p = 0.001), reduced phonation range (p = 0.007) and shorter closed phase of vocal fold vibration (p = 0.006) in comparison to healthy controls. Females with CC had reduced fundamental frequency in connected speech (p = 0.009). There was consistent overlap between the participants with CC and those with PVFM. Duration of closed phase and fundamental frequency were lower in the participants with CC and PVFM than in those with muscle tension dysphonia. Conclusion: These results confirm abnormalities in acoustic and EGG voice features in CC and PVFM.
