Researchers at the Veteran Medical Center in Long Beach, Calif., have developed, produced and performed the first test of the world's first automated human leg prosthesis, which is managed in real time by using the signals of the electroencephalogram (EEG). EEG signals are read using brain-computer interface (brain-computer interface, BCI) and interpreted in the management team robotic prosthesis RoGO (robotic gait orthosis), which stimulates the patient's leg muscles.
During the test the patient, whose feet were wearing dentures RoGO, wore a "cap" with EEG sensors. Additionally, the patient's body at key points established EMG-electrodes, and on foot — a gyroscopic sensor position. On a computer screen, which was located at the patient's eye, the patient was given educational instruction. And what was the result can be seen in the below video.
Currently, the system BCI-RoGO can be used to help patients with nerve damage feet. But in the future, the researchers intend to finalize the hardware and software so that the system can help to go to people with certain types of spinal cord injuries, which are known to be responsible for all functions of movement of the musculoskeletal system.
