Introdução: As oscilações durante a marcha parecem estar alteradas em pessoas com Doença de Parkinson (DP), sugerindo uma instabilidade postural associada com o risco de queda. A realização de dupla-tarefa pode constituir um factor de risco de queda para uma pessoa com DP. Objectivos: Estudar a relação entre as oscilações da cintura pélvica, o risco de queda e a atenção e a influência da dupla tarefa sobre o padrão de marcha das pessoas com DP. Métodos: Estudo transversal observacional com amostra de 20 participantes: DP com historial de quedas (n=7), DP sem historial de quedas (n=7) e saudáveis sem historial de quedas (n=6). Avaliou-se o risco de queda e o grau de atenção e mediram-se as oscilações da cintura pélvica e a velocidade de marcha em duas provas: tarefa simples dupla tarefa. Resultados: Não existiu relação entre as oscilações da cintura pélvica, o risco de queda e a atenção nas pessoas com DP. A velocidade de marcha diminuiu significativamente nos dois grupos sem quedas na dupla tarefa e, destes, no das pessoas com DP houve também alterações significativas das oscilações da cintura pélvica. Conclusões: As oscilações da cintura pélvica não parecem estar relacionadas com o risco de queda ou a atenção nas pessoas com DP. As pessoas com DP que caem tendem a andar com menos velocidade/estabilidade independentemente da tarefa e as pessoas com DP sem quedas parecem alterar o seu padrão de marcha conforme a tarefa e andam tendencialmente com mais estabilidade.
ABSTRACT - Introduction: Gait oscillations seem to be altered in people with Parkinson's disease (PD), suggesting a postural instability associated with an increased risk of falling. Performing dual-task can be a risk factor for falling for a person with PD and attention impairment. Objectives: To study the relationship between pelvic oscillations, risk of falling, and attention, and how the dual-task influences the gait pattern of people with PD. Methods: A cross-sectional observational study was carried out on a sample of 20 participants: PD with a history of falls (n=7), PD without a history of falls (n=7), and healthy subjects without a history of falls (n=6). Fall risk and attention were evaluated and pelvic oscillations and gait speed were measured in two tests: simple task and dual-task. Results: No relationship was found between pelvic oscillations, risk of falling, and attention in people with PD. Gait speed decreased significantly in the two groups without a history of falls when performing dual-task and, of these, in the group of people with PD, there were also significant changes in pelvic oscillations. Conclusions: Pelvic oscillations don’t seem to be related to falling risk or attention function in people with PD. People with PD and a history of falls show a tendency to walk slowly and with more instability regardless of the type of task and people with PD without a history of falls seem to change their gait pattern according to the type of task and show a tendency to walk with more stability.
