Dupla tarefa motora-cognitiva de fluência verbal em idosos hígidos, com comprometimento cognitivo leve e com doença de parkinson: estudo comparativo

Abstract

Objective: To describe, compare and analyze the influence of dual tasks of verbal fluency (VF) on the postural control of healthy subjects compared to subjects with MCI and PD. Methods: 36 elderly (12 healthy, 12 with MCI and 12 with PD) were submitted ten measuring instruments. Results: The area and total displacement were altered for the 3 groups when compared to open eyes and closed eyes (p <0.05). There were changes in the total displacement and area after the addition VF task addition for the three groups (p <0.05). No significant difference was found in the laboratorial variables of postural control between groups (p> 0.05). The emission of animal names generated changes in the postural control in the healthy and MCI groups (p <0.05). Conclusions: The addition of VF task modified the total displacement and the area for the three groups, which were similar for postural control in single and double tasks with VF.
