A new study shows that a 26-year-old man has succeeded in taking steps after using his brainwave control system and his weight-bearing harness system five years after his legs. The study was published in the Journal of NeuroEngineering and Rehabilitation on the 23rd of this month. In order to regain the ability to walk, the patient wears a special hat on his head, and his hat is covered with electrodes to detect his brain's electric wave signal, which is then converted into an electrical signal. These electrical signals are similar to those used in EEG testing. These electrical signals are sent to a computer that can "decode" these electrical signals. Then, using the decoded information, the computer simulates the nerve signal that the leg nerve should receive, that is, the computer sends a command to another device, which can stimulate the nerves of the human leg and cause muscle movement, thereby helping this People take steps. Using this system, the patient with spinal cord injury was able to walk about 12 feet (3.66 meters) after five years of surgery. He used a walker and wore a harness that provided some weight support to prevent leg muscle weakness from causing him to fall. “Even after years of spinal cord injury, the legs are unusable. But the brain is not affected too much, and it seems that it still produces nerve signals and corresponding brain waves that can be used to indicate basic walking movements.†The co-author of the study First, An Do, Irvine, assistant professor of neurology at the University of California, Irvine, said in a statement: "We found that after complete spinal cord injury, you can restore intuition and the brain can control walking." In previous studies, a similar brain control system (called a brain-computer interface) has been used to move a prosthesis, such as a robotic arm. Last year, an embarrassing patient, Juliano Pinto, used his brain to control the exoskeleton and completed the first penalty in the 2014 World Cup. And this new study provides a proof that a patient with a completely paralyzed leg can still use the brain to control the legs, and if combined with the brainwave control system, can be used to stimulate the leg muscles and resume walking. However, the researchers agree that the study is based on only one patient and therefore requires more participants to see if other patients can benefit from the technology. However, the success of the system is an important step in restoring or improving the leg muscles, and has been a good attempt to further improve the system and apply it to more patients. The researchers mentioned that before the man used the system, he first conducted some psychological training to learn to use his brain waves to control the legs in virtual reality. Although the legs belong to the patient, his brain is not directly controlled. In addition, the patient also received physical training to strengthen the leg muscles. Then, when he was supported by a strap and a walker, the patient used a brain control system to practice walking. The researchers said that after 20 pauses, he was able to walk slowly on the ground. In this case, the patient-controlled device is called Parastep, which provides electrical stimulation of the leg muscles to simulate nerve activity to promote muscle movement. The study used the patient's own brain signals to successfully stimulate and control the leg muscles. This coupling of brain signals-leg stimulation motivates patients to believe that they can control their legs and thus have more confidence and desire for walking. Researchers also believe that in the future, technological improvements may allow the entire system to be miniaturized and partially implanted into the patient's body, such as the brain, spinal cord, and other areas. This way the patient will not need to carry out cumbersome equipment installation and disassembly. In addition, electrical stimulation of the back muscles can help activate the muscles and help the patient keep the body upright, eliminating the need for straps and walkers to support the body. The researchers tried to conduct the study in the current study, but this stimulation would interfere with the detection of brain waves in patients. How to balance the two is an important issue. The researchers concluded, "In the future, developing new algorithms to filter out these interfering signals, or developing a fully implanted brain-computer interface system, may allow us to overcome this problem so that patients do not need external equipment.
