UC Irvine BCI research has enabled a a paraplegic to walk, with support, for 12 feet, without an exoskeleton. The hope is that this will lead to a new generation of BCI stimulation technology that will allow the disabled to walk for longer periods with minimal support. The study was led by Samueli School of Engineering‘s Zoran Nenadic and An Do.
A computer linked the 28 year old man’s brain to his legs over a Bluetooth connection, bypassing the severed region of his spinal cord. EEG derived brain signals were relayed to electrodes on his knee, triggering walking movements.
Prior to the experiment, the man underwent extensive training to strengthen his muscles and learn to control a virtual avatar using the BCI device. He also made similar movements in the lab while slightly suspended.
The team would like to miniaturize and implant the EEG components in the brain. They believe that this could give patients more precise control the and the ability to “sense” pressure.
