AIMS To determine the accuracy of the bedside volume-viscosity swallow test (V-VST) for clinical screening of impaired safety and efficacy of deglutition. METHODS We studied 85 patients with dysphagia and 12 healthy subjects. Series of 5-20 mL nectar (295.02 mPa.s), liquid (21.61 mPa.s) and pudding (3682.21 mPa.s) bolus were administered during the V-VST and videofluoroscopy. Cough, fall in oxygen saturation > or =3%, and voice changes were considered signs of impaired safety, and piecemeal… CONTINUE READING
