Fatigue is considered a symptom of high incidence in patients with Parkinson's disease (PD), which may influence the walking. Physical activity counteracts the effects of PD and fatigue. However, the relationship between physical activity and fatigue and the influence of fatigue-inducing on gait parameters in PD patients compared with control subjects are not clear. To fill these gaps, two studies are proposed: A) Study 1 aimed to compare and correlate the subjective perception of fatigue with the physical activity level in PD patients and in individuals not affected by PD. Eighty subjects, 40 patients with PD and 40 subjects without PD, will participate in this study. The participants, within their groups, will be distributed in actives (20) and inactives (20) according to scores on the modified Baecke questionnaire for the elderly. The Multidimensional Fatigue Inventory will be used to verify the subjective perception of fatigue. The relationship between physical activity level and subjective perception of fatigue for each group will be observed through the correlation tests. Comparison of the subjective perception of fatigue will be conducted through analysis of variance with group and physical activity level as factors. B) Study 2 aims to analyze the effect of fatigue on kinematic, kinetic and electromyographic variables on free and adaptive gait parameters in PD patients and individuals not affected by PD, considering the level of physical activity. To do this, 40 subjects, 20 PD patients (10 active and 10 inactive) and 20 subjects without PD (10 active and 10 inactive) will be selected. Three attempts will be made to the conditions of free and adaptive walk before and after induction of fatigue, achieved by the task of sitting and standing on a chair. Kinematic, kinetic and EMG variables will be collected during the attempts. Analysis of variance will be conducted considering group and fatigue as factors and the physical activity level as a covariate. It is hoped that the results of this project will contribute to a better understanding about the control of locomotion and, therefore, to support the intervention in patients with PD.
