The specificities of the motor system lead people to present skills to perform some movements in an automatic way after learning. Acquiring the automaticity of the movements is usually associated with reducing the demands of attention control. Thus, automatization represents a reduction in interference that undermines performance in dual task conditions. It was carried out a search on the databases of Pubmed, Scopus, SciELO e Lilacs, to understand the physiology of automaticity and analyze the use of electroencephalogram as a means of research in automatization. In this context, the study aims to verify the employment of the electroencephalogram as a resource in the analysis of the motor skills involved in the movement automatization.Key-words: motion, attention, electroencephalogram.

Objective. The epidemic of infection by the Chikungunya virus currently represents one of the largest epidemiological occurrences in south and Central America, being considered a serious public health problem, since, in addition to the typical clinical symptomatology, there are reports of Associated neurological diseases, such as Guillain-Barré Syndrome. Guillain-Barré Syndrome is an acute inflammatory demyelinating polyneuropathy that leads to various functional impairments, such as flaccid paralysis, areflexia and muscular weakness. Method. A case of Guillain-Barré Syndrome was reported after infection by the chikungunya virus. Results. The case presented severe functional complications, with a picture of flaccid tetraparesis, with motor and sensory impairment, mainly in the left hemibody. Conclusion. From this perspective, from this report, and from reports of previous cases, it is considered that chikungunya virus infection may cause Guillain-Barré Syndrome, among other severe neurological complications, in an acute and progressive way, especially in areas considered endemic.
