Motor Rehabilitation with BCI - Lecture from The BCI & Neurotechnology Spring School 2020

Описание: The first talk was from Christoph Guger about Motor rehabilitation with BCI, which was the topic of day 2.

Christoph he explained who he uses the motor imagery principle for recoveriX, a BCI-based stroke rehabilitation system. Motor Imagery leads to changes over the sensorimotor cortex and are called “even-related desynchronization” (ERD). The BCI is able to pick up these changes when a stroke patient is imaging a hand or foot movement and triggers a functional electrical stimulation of the corresponding limb.

As an instruction, recoveriX shows a virtual avatar that is performing a hand movement on a computer screen. This prompts the patient to imagine this movement.

For recoveriX treatment, 16 active EEG electrodes are necessary on the patient’s head for high quality recordings. The BCI algorithm analyzes the brain activity in real-time. When the BCI system detects a right-hand movement imagination by the patient, the right hand will be stimulated immediately for about 4-5 seconds.

This closed-loop setup pairs the cognitive processing again with motor behavior. Furthermore, acute, sub-acute and chronic cases were explained to pin point the functional improvements that recoveriX is producing.
