BCI Post-stroke Neurorehabilitation

University Hospital, Montpellier20 enrolled

Overview

The goal is to evaluate the potential of a EEG based BCI (Brain-Computer-Interface) connected to a non-invasive pneumatic glove for rehabilitation of hand-movements post-stroke.

Brain computer interfaces (BCI) encompasses the usage of the brain signals to compensate for lost physical function. The current protocol evaluates the therapeutic potential of a EEG based driven BCI that is connected to a non-invasive pneumatic glove for rehabilitation of hand flexion/extension post-stroke. The system non-invasive, portable and low-cost. The utility and usability of the system will be investigated at two levels. First by means of questionnaires for patients and therapist and second by means of in depth analysis of the EEG signals during intended, imagined and passive driven hand movements in relation to no movement at all and the capacity of the BCI to distinguish between these conditions.

Conditions

Poststroke/CVA Hemiparesis Paralytic Stroke Hand Flaccid Paralysis

Interventions

EEG based Brain Computer InterfaceDEVICE

Using EEG signals to classify brain activity being 'rest' or 'active' to control the attached pneumatic glove and close the sensory-motor loop between intentional/mental movement and physical (though passive) movement.

Outcomes

Primary Outcomes

Performance of the BCI-system (evaluation of performance through patient questionaires & the performance of the BCI classifier during intended and imagined hand movements)
