In Portugal, stroke is considered the leading cause of death and disability associated with cognitive and motor sequelae. The incidence of dysphagia ranges from 22% to 65% of patients (Ramsey, Smithard and Kalra, 2003). Several studies reveal that 30 to 40% of institutionalized elderly people have swallowing disorders, which results in a high incidence of complications due to aspiration (World Gastroenterology Organization, 2004). Based on these assumptions, a systematic review was performed to minimize the risk of ad hoc evaluation and by identifying the available low cost and easy access resources in order to enhance health gains. The methodology was guided by Cochrane Handbook and was designed to answer the following question: “What methods of non-invasive evaluation of dysphagia in people with neurological disease with demonstrated validity and reliability are published?” Therefore we conducted a search for primary studies, published since 2005, in the most relevant computerized databases. From that search, we identified two studies with the results of the application of two distinct scales used in the diagnosis of dysphagia in stroke survivors (in acute and / or rehabilitation), one of which also assessed the risk of aspiration. The results may predict high gains in health with the application of these scales, although further studies are needed to obtain a substantial sample.
