[en] Introduction: in post-stroke patients, dual tasks (simultaneous performance of motor and cognitive tasks) are altered: cognitive-motor interferences are greater than in healthy population. So there is a necessity of studying the effects of this dual task interference and how it is possible to design effective physiotherapeutic interventions to improve the movement of these patients. Objective: the systematic review objective is to study and update the scientific evidence which was found in different databases, that provide information about the effects of cognitive-motor interferences during dual tasks in post-stroke patients. Methodology: a systematic search was carried out in three databases (Pubmed, Scopus and Web of Science). During studies selection, we took into account papers in which patients had motor impairment and no or little cognitive dysfunction. Also, we looked at papers studying cognitive-motor interference and its application in Physical Therapy interventions. Results: the search in different databases provide 1296 articles. Eighteen of them were selected because they met the predefined inclusion criteria. Studies analysis showed beneficial results of cognitive-motor interferences during the interventions with dual tasks, the accomplishment of the tasks in different difficulty levels and the application of new technologies for the realization of the motor task. Conclusion: during dual tasks, post-stroke patients have greater cognitive-motor interference compared to simple tasks due to motor impairments and to the attentional capacity which has to be divided between both tasks. The training with dual tasks in post-stroke patients achive significant improvements in lower limbs showing an improvement of spatiotemporal parameters of gait in simple tasks and dual tasks, with slight evidence that these improvements are maintained long term.

[gl] Introdución: nos pacientes post-ictus, as tarefas duais (realización simultánea dunha tarefa motora e unha cognitiva), atópanse alteradas: as interferencias cognitivo-motora son maiores que na poboación san, polo que xorde a necesidade de estudar os efectos desa interferencia nas tarefas duais e cómo e posible deseñar intervencións fisioterápicas, efectivas para mellorar o movemento destes pacientes. Obxectivo: o obxectivo desta revisión sistemática é estudar e actualizar a evidencia científica, atopada nas distintas bases de datos utilizadas, que acheguen información sobre os efectos da interferencia cognitivo-motora durante as tarefas duais en pacientes post-ictus. Metodoloxía: realizouse unha busca sistemática de artigos en tres bases de datos (Pubmed, Scopus e Web of Science). Para a selección dos artigos tívose en conta que os participantes presentasen afectación motora e nula ou escasa afectación cognitiva, que realizasen tarefas duais nas que se estudara a interferencia cognitivo-motora, e a súa aplicación nas intervencións fisioterápicas. Resultados: a busca nas distintas bases de datos proporcionaron 1296 artigos, dos cales se seleccionaron 18, que cumprian os criterios de inclusión predefinidos. A analíse dos estudos amosou resultados beneficiosos das inteferencias cognitivo-motora durante as intervencións con tarefas duais, da realización das tarefas en diferentes niveis de dificultade e da aplicación de novas tecnoloxías para a realización da tarefa motora. Conclusión: os pacientes post-ictus durante as tarefas duais presentan maior interferencia cognitivo-motora en comparación coas tarefas simples debido as afectacións motoras e a afectación da capacidade atencional que ten que dividirse entre as duas tarefas. O adestramento con tarefas duais en pacientes post-ictus acada melloras significativas en membros inferiores, amosándose unha melloría dos parámetros espazo-temporais da marcha nas tarefas simples e tarefas duais, apreciándose pouca evidencia de que esas mellorías se manteñen a longo prazo.
