The Effect of Beta-blockers in Substance P Levels and the Swallowing Function

An overall assessment is going to be carry out by a multidisciplinary team during the visit. Swallowing assessment is going to be performed during the visit. We are going to use: (i) the Eating Assessment Tool (EAT-10), which is a short 10-item, easy to use, self-administered questionnaire \[4\]. Although the EAT-10 is considered to be predominantly a questionnaire on FHS, some items on HR-QoL are also included. The sum score of this 10-item questionnaire ranges from 0 to 40, and (ii) the Sydney Swallowing Questionnaire (SSQ) to clinically assess the severity of the symptoms of dysphagia, if present. All subjects are going to be submitted to the volume-viscosity swallow test (V- VST)
