A doença de Alzheimer (DA) é uma doença neurodegenerativa progressiva que provoca demência. É decorrente de uma disfunção cerebral, afetando, inicialmente, a formação hipocampal e o centro de memória de curto prazo, ocorrendo perturbação de múltiplas funções cognitivas e motoras. O objetivo deste estudo foi analisar a cinemática da marcha de pacientes portadores de DA, identificando a presença do dano cognitivo por meio de testes como o Mini Exame de Estado Mental e o Clinical Demential Rating. Constituiu-se de uma pesquisa descritiva com delineamento transversal. Foram analisados um grupo controle (GC) composto por 10 idosos sem alterações cognitivas e um grupo Alzheimer (GA) composto por 8 idosos com demência. A coleta de dados foi realizada por meio do Sistema VICON, e marcadores foram fixados em determinados pontos anatômicos dos membros inferiores. Com os resultados obtidos neste estudo, pode-se observar que os indivíduos do GA apresentaram valores significativamente menores quando comparados ao GC na cadência (p = 0,006), velocidade (p = 0,001), comprimento do passo (p = 0,01) e passada (p = 0,005). Portanto, pode-se concluir que os indivíduos com Doença de Alzheimer, além da perda cognitiva, apresentam alterações nas variáveis espaçotemporais estudadas, e que esta perda motora interfere significativamente na cinemática da marcha.
Palavras-chave: doença de Alzheimer, fenômenos biomecânicos, marcha.
