Aerobic Exercise and Cognitive Training in Patients With Stroke

Fondazione Don Carlo Gnocchi Onlus30 enrolled

Overview

The goal of this clinical trial is to test the effects of aerobic exercise and BDNF on patients with ischemic and hemorrhagic stroke during a computerized cognitive training. The main questions it aims to answer are: 1. Does a moderate intensity aerobic exercise, prior to a cognitive training, allow a better performance? 2. Is it possible to exploit the timing of rehabilitation interventions to obtain greater effects? Participants will be divided in 2 groups. The experimental group will first perform 20 minutes of pedaling as a moderate intensity aerobic exercise. It will then participate in one-hour cognitive training sessions, with the aim of training attentional, working memory and executive functions. The control group will carry out the same interventions but in reverse order. The researchers will compare the results of the cognitive training in the two groups to verify if the order of the interventions influences the results themselves.

Interventions

Neuropsychological evaluationBEHAVIORAL

Each participant will undergo a complete neuropsychological evaluation, both before and at the end of the clinical trial, with the aim of detecting any changes or improvements.

BDNF evaluationBIOLOGICAL

During the first and last clinical trial session, each participant will undergo two blood samples, one before and one at the end of the ride, to check levels of Brain Derived Neurotrophic Factor (BDNF).

Pedaling as a moderate intensity aerobic exerciseBEHAVIORAL

During each session, each participant will perform 30 minutes of pedaling as a form of moderate intensity physical activity.

Cognitive TrainingOTHER

During each session, each participant will carry out 60 minutes of cognitive training through specific exercises for the attentional, executive and working memory functions.

VO2 assessmentDIAGNOSTIC_TEST

To determine the individual moderate intensity for each patient, a VO2 consumption assessment will be made. The examination will be carried out using an exercise bike and a mask for the calculation of metabolic oxygen consumption. The 3 MET threshold to reach in pedaling will be calculated (to define it of moderate intensity), in order to elicit the release of BDNF.

Outcomes

Primary Outcomes

Neuropsychological test scores

The experimental hypothesis is to obtain better scores in the experimental group on the neuropsychological tests used. T-tests and delta scores will be used to determine the quantitative change in the score.

Time frame: Change in the neuropsychological test scores at 1 month

Secondary Outcomes

Number of errors committed in the cognitive exercises

For each exercise used in the cognitive training, numerical data will be extrapolated to determine the number of errors committed and the progress achieved. T-tests will be carried out to verify if the experimental group had a better performance during the training than the control group.

Time frame: One month
