Abstract

Background: Many studies show the beneficial effects of overground gait training in stroke patients. However, it is not know whether it is able to induce changes in brain-derived neurotrophic factor (BDNF) levels, which could positively influence neurophysiological mechanisms. Objective: To evaluate the effect of a single session of light-to-moderate intensity walk on BDNF serum levels and its precursors (proBDNF) in chronic ischemic stroke patients. Methods: Patients were asked to walk for 30 minutes in the target heart rate training zone (30-60% of maximal heart rate). Blood samples were collected immediately before and after a single session. Results: Fifteen individuals with 60.8 (7.7) years old participated of this study. There was no significant difference in proBDNF (p=0.573) and BDNF (p=0.563) serum levels between pre- and post-session. Conclusion: This study used light-to-moderate intensity because the goal is to approach the gait training in clinical setting. The lack of increase in BDNF levels can be explained by two reasons: the intensity zone of the heart rate selected during the session and not having a gradual increase in this intensity.
