ABSTRACT Purpose Cerebrovascular accident is an important Public Health problem because of the high rates of mortality and sequelae such as language disorders. The conceptual health changes have led to the incorporation of functional and social aspects in the assessments as proposed by the World Health Organization in the International Classification of Functioning, Disability and Health. The purpose was to evaluate and classify language aspects, functionality and participation of post-stroke individuals based on the concepts of the International Classification of Functioning, Disability and Health and characterize the sociodemographic profile of participants. Methods Data collection was carried out through the application of a clinical instrument to evaluate language, participation and functionality in fifty individuals based on the International Classification of Functioning, Disability and Health. Results The age of the participants varied between 32 and 88 years, and the majority were elderly men. Among body functions, the participants reported more difficulties in “memory functions”. As for activity and participation, more difficulties were reported in “recreation and leisure”. As for environmental factors, the component “healthcare professionals” was indicated as a facilitator by the majority of participants. Conclusion The results show the impact of language difficulties in the lives of post-stroke adults and reinforce the applicability of the International Classification of Functioning, Disability and Health as an important complementary tool for assessing language, functionality and participation in a comprehensive and humane approach, towards the improvement of health assistance in ambulatory care.
