V-VST algorithm. Patients with safe swallow started the exploration with a 5 mL nectar bolus, followed by 10 and 20 mL nectar boluses, then performed the water with increasing volume and finally completed the pathway with the three water boluses to explore efficacy of swallow. If the patient presented signs of impaired safety at nectar or water viscosities, the series was interrupted and the pudding series was assessed. V-VST, volume-viscosity swallowing test
