A stroke might inhibit your ability to move, but maybe not your ability to imagine movement! Imagine a hand or a foot movement – the imagination triggers nearly the same activity in the brain as a real hand or foot movement –this is what exactly we can use for our therapy!
With three different kinds of feedback, we can improve your chances for successful therapy.
Imagine a hand or a foot movement. Our EEG cap can measure your brainwaves, which reflect your motor imagery. Motor imagery produces brain activity similar to an active movement. The recoveriX system analyses this brain activity and can determine whether the motor imagery was correct.
The simulation on the screen makes your movement imagination visible. You sit in front of a screen, where you can see the hands or feet of an “avatar” (virtual person). This should give you the feeling of watching your own movements in front of a mirror. If the system identifies a correct imagination of the movement (such as a right hand movement), the avatar moves the right hand. So you can control the avatar’s movements with your mind, which should help you relearn to control your own movements.
The imagined movement leads to electrical stimulation of the affected muscles – without pain! For this stimulation, two electrodes are placed (for example) on the dorsiflexors of the wrist. If the system recognizes a correct motor imagery, the muscles get electrically stimulated, causing a real movement. This should help you re-learn how to initiate movement, and thus make movement possible again.
These three rehabilitation components help the brain reorganize to be able to perform movements again independently.
At the end of every therapy session, the system shows you a complete evaluation of your training success, and delivers a clear representation of your improvements.
