ALMEIDA, Rita de Cássia de Araújo; HAGUETTE, Renata Cavalcante Barbosa  and  ANDRADE, Izabella Santos Nogueira de. Swallowing with and without verbal commands: videofluoroscopy findings. Rev. soc. bras. fonoaudiol. [online]. 2011, vol.16, n.3, pp.291-297. ISSN 1982-0232.

Purpose: To characterize the swallowing process of different food consistencies and quantities, with and without verbal commands, through videofluoroscopy. METHODS: Quantitative cross-sectional, observational study held in the period between January and March 2010 with 40 healthy subjects with no apparent signs of swallowing problems. Mean age was 23 years and 5 months (SD±2.5), with a minimum age of 20 years and a maximum of 30 years, and 87.5% of the subjects were female (35/40). A videofluoroscopy swallowing study (VFSS) was carried out with the ingestion of barium in the liquid, thick liquid, pureed and solid consistencies. Two swallowing tests were held during the administration of the liquid consistency, with and without verbal commands. The place of beginning of the pharyngeal phase of swallowing in different structures was analyzed, as well as the presence of premature spillage of food, delayed oral transit time, multiple swallowing, stasis, and laryngeal penetration and/or aspiration in both situations. RESULTS: The beginning of the pharyngeal phase took place in the base of the tongue and in the valleculae for most consistencies and quantities, with the exception of the liquid swallowing (5 ml), which started in the valleculae. There was no influence of the verbal command both in the place where the pharyngeal phase of swallowing started, and the presence of stasis of residue. However, the command was effective in reducing oropharyngeal findings. CONCLUSION: The pharyngeal phase of swallowing occurred in the base of the tongue and valleculae. The verbal commands influenced the dynamics of swallowing.
