Neurofeedback for Upper-limb Recovery After Stroke

Rennes University Hospital32 enrolled

Overview

Interventional study with minimal risks and constraints, prospective, monocentric.

Neurofeedback (NF) consists on training self-regulation of brain activity by providing real-time information about the participant brain function NF approaches in stroke are usually based on real-time monitoring of brain activity using EEG-NF and involve chronic stroke. Recent studies have revealed the potential of combining EEG and fMRI to achieve a more efficient and specific self-regulation, which may be critical in clinical applications. The aim of this study is to optimize the neurofeedback method coupling EEG and fMRI in healthy subjects then to evaluate the effect of an EEG-NF and a neurofeedback coupling EEG and fMRI versus motor imagery on recovery in the early and chronic stage after stroke.
