Objective: To investigate upper limb (UL) energy demand during unilateral arm crank submaximal exercise testing in individuals with stroke compared with healthy controls and the relationship between UL energy demand and UL activity in individuals with stroke.
Design: Cross-sectional, observational study.
Setting: Research laboratory.
Background: Individuals with stroke have low physical activity levels and spend high amount of time in low-energy expenditure activities.
Objective: To investigate the effects of aerobic treadmill training on physical activity levels and time spent in low-energy expenditure activities (primary outcomes), as well as on cardiorespiratory fitness, endurance, depression, mobility, quality of life and participation (secondary outcomes) after stroke.
Methods: A randomized controlled trial, with 22 adults with chronic stroke was performed.
Aim: To describe exercise preferences and to investigate the contribution of exercise preferences, walking ability, and current levels of physical activity in predicting exercise adherence in individuals with chronic stroke.
Methods: For this exploratory study, exercise adherence was measured using the first question of the first section of the Exercise Preference Questionnaire (stroke)-Brazil (EPQ (stroke)-Brazil). Nine independent variables were included as potential predictors of exercise adherence: the seven factors of the EPQ (stroke)-Brazil, walking speed, and level of physical activity.
Objectives: To investigate the incidence and potential predictors of upper-limb contractures, three months after stroke.
Design: Prospective cohort study.
Methods: Consecutive sample of individuals with hemiparesis due to stroke, admitted to a public hospital in Brazil.
Background: The Exercise Preference Questionnaire (EPQ) captures exercise preferences and measures personal factors, that influence motivation and adherence to exercise in stroke subjects.
Objectives: To perform the cross-cultural adaptation of the EPQ into the Brazilian-Portuguese language and to evaluate its measurement properties.
Methods: The EPQ was cross-culturally adapted and primarily tested in 30 chronic stroke subjects.
Background: It is important to include large sample sizes and different factors that influence the six-minute walking distance (6MWD) in order to propose reference equations for the six-minute walking test (6 MWT).
Objective: To evaluate the influence of anthropometric, demographic, and physiologic variables on the 6 MWD of healthy subjects from different regions of Brazil to establish a reference equation for the Brazilian population.
Method: In a multicenter study, 617 healthy subjects performed two 6 MWTs and had their weight, height, and body mass index (BMI) measured, as well as their physiologic responses to the test.
Background: The anaerobic threshold (AT) provides information on functional capacity in heart failure (HF). However, the visual determination of the AT by ventilatory methods is subjective, being susceptible to differences between examiners.
Objective: To evaluate the inter- and intra-examiner reproducibility in the determination of the AT in patients with mild to moderate HF, using visual-graphic and V-slope methods.
