 The present study examines aerodynamically measured voluntary cough and its relationship with aspiration during swallow in dysphagic patients. We enrolled 24 male patients with dysphagia (mean age:73.0 years) who were examined by videofluorography and 17 healthy males (mean age:69.4 years) as a control group. We measured voluntary cough parameters including inspiratory phase duration, inspiratory peak flow, compression phase duration, expiratory rise time, expiratory peak flow, and cough volume acceleration. We compared the control and dysphagic groups, then separated the dysphagic group into non-aspiration and aspiration groups using a penetration-aspiration scale, and finally compared voluntary cough parameters between them. All parameters, except inspiratory and compression phase durations, differed significantly between the dysphagic and control groups. In addition, the aspiration group had prolonged expiratory increase times, depressed expiratory peak flow, and decreased cough volume acceleration when compared with the non-aspiration group. Voluntary cough decreased in the dysphagic group, and we considered that a disordered expiratory phase was specifically related to aspiration.
