OBJECTIVE: To determine the effect of sour and cold food in the pharyngeal transit times of patients with stroke. METHODS: Patients participating in this study were 30 right-handed adults, 16 of which were male and 14 were female, aged 41 to 88 (average age 62.3 years) with ictus varying from 1 to 30 days (median of 6 days). To analyze the pharyngeal transit time a videofluoroscopy swallow test was performed. Each patient was observed during swallow of a 5 mL paste bolus given by spoon, totaling four different stimuli (natural, cold, sour and cold sour), one at a time, room temperature (22\u00baC) and cold (8\u00baC) were used. Later, the tests were analyzed using specific software to measure bolus transit time during the pharyngeal phase. RESULTS: The results showed that the pharyngeal transit time was significantly shorter during swallow of cold sour bolus when compared with other stimuli. Conclusion - Sour taste stimuli associated to cold temperature cause significant change in swallowing patterns, by shortening the pharyngeal transit time, which may lead to positive effects in patients with oropharyngeal dysphagia.<\/jats:p>","DOI":"10.1590\/s0004-28032010000100004","type":"journal-article","created":{"date-parts":[[2015,3,2]],"date-time":"2015-03-02T16:39:44Z","timestamp":1425314384000},"page":"18-21","source":"Crossref","is-referenced-by-count":50,"title":["The influence of sour taste and cold temperature in pharyngeal transit duration in patients with stroke"],"prefix":"10.1590","volume":"47","author":[{"given":"Paula Cristina","family":"Cola","sequence":"first","affiliation":[{"name":"S\u00e3o Paulo State University, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Rita","family":"Gatto","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberta Gon\u00e7alves da","family":"Silva","sequence":"additional","affiliation":[{"name":"UNESP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9 Augusto","family":"Spadotto","sequence":"additional","affiliation":[{"name":"UNESP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur Oscar","family":"Schelp","sequence":"additional","affiliation":[{"name":"UNESP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Aparecida Coelho de Arruda","family":"Henry","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","first-page":"221","article-title":"Mechanical-thermal stimulation of the palatoglossus pillars","volume":"44","author":"Alvite MFL","year":"2007","journal-title":"Arq.
