Abstract(s)
O estudo das alterações motoras não é recente, mas a sua concetualização como característica intrínseca da esquizofrenia não está clara. Por seu lado, patente está a inter-relação entre competências cognitivas e motoras, daí a pertinência de estudar o comportamento motor em tarefa simples e dupla. Objetivo: Analisar o controlo postural e a mobilidade funcional em tarefa simples e dupla de pessoas com diagnóstico de esquizofrenia, comparativamente a um grupo controlo. Métodos: Utilizaram-se a plataforma de forças para avaliar o Sit-to-Stand e o equilíbrio estático; o Timed Up and Go para avaliar a mobilidade funcional; e o programa Kinovea para analisar a orientação e estabilidade posturais durante o movimento de Sit-to-Stand-to-Sit. Recorreu-se ao teste t-Student e de Mann-Whitney, tal como à ANOVA para medidas repetidas com modelo misto. Resultados: Participaram 27 indivíduos, 13 com diagnóstico de esquizofrenia e 14 sem diagnóstico. Não se encontrou correlação entre as variáveis clínicas e os domínios avaliados, tal como não houve diferenças significativas no desempenho cognitivo por grupos. Porém, o desempenho motor mostrou discrepâncias estatísticas entre grupos para alguns dos testes aplicados. Conclusão: Esta investigação parece sugerir a existência de alterações motoras associada à esquizofrenia, principalmente quando em tarefa dupla. Ainda assim, mais estudos são necessários.
The study of motor disorders is not recent, but its conceptualization as an intrinsic characteristic of schizophrenia is unclear. On the other hand, the interrelationship between cognitive and motor skills is evident, hence the relevance of studying motor behavior in simple and dual task. Objective: To analyze postural control and functional mobility in simple and dual task of people diagnosed with schizophrenia, compared to a control group. Methods: The force platform was used to evaluate the Sit-to-Stand and the static balance; the Timed Up and Go to evaluate functional mobility; and the Kinovea program to analyze postural orientation and stability during the Sit-to-Stand-to-Sit movement. The t-Student and Mann-Whitney test was used, as well as the ANOVA for repeated measures with a mixed model. Results: 27 individuals participated, 13 with diagnosis of schizophrenia and 14 without diagnosis. No correlation was found between the clinical variables and the evaluated domains, just as there were no significant differences in cognitive performance by groups. However, motor performance showed statistical discrepancies between groups for some of the applied tests. Conclusion: This research seems to suggest the existence of motor changes associated with schizophrenia, mainly when in a dual task. Still, more studies are needed.
