Closed loop EEG/BCI/VR/physical therapy system to control gait, prosthetics

Earlier this year, University of Houston’s Jose Luis Contreras-Vidal developed a closed-loop BCI/EEG/VR/physical therapy system to control gait as part of a stroke/spinal cord injury rehab program.  The goal was to promote and enhance cortical involvement during walking.

In a study, 8 subjects walked on a treadmill while watching an avatar and wearing a 64 channel EEG headset and motion sensors at the hip, knee and ankle.

The avatar was first activated by the motion sensors, allowing its movement to precisely mimic that of the test subject. It was  then controlled by the brain-computer interface, although this was less precise than the movement with the motion sensors. Contreras-Vidal believes that as subjects learn how to use the interface, the result will be closer to that of the sensors. The researchers reported increased activity in the posterior parietal cortex and the inferior parietal lobe, along with increased involvement of the anterior cingulate cortex.

The team built on this reasearch  to demonstrate how brain activity is used to identify different terrains to develop prosthetics that automatically adjust to changing ground conditions in real time.
