The paraplegic patients are again implanted

The trend is that more and more decades, science and medicine use technology to solve the major problems of human health. We are not sure when the final crawler is displayed or how we can transfer data from our brain to the computer. But what we know is so small, big steps that go in this direction. Three paraplegic people felt their feet again and managed to walk.
A Swiss neurologist and neurosurgeon who had paralyzed people with their legs for years to re-implant the implants into the spinal cord. After a few months of training, the patients regulated their feet and took action themselves without needing electrical stimulation.
Among those responsible, Grégoire Courtine is a renowned neuroscientist at the Lausanne Federal Technical College (EPFL), who spent years trying to investigate how to recover the injured spinal cord. She has previously shown the development of monkeys and rats. Now, in co-operation with Jocelyne Bloch's Neuroscience, the Vaud University Hospital Center has been able to reach three paraplegic men thanks to spine-based wireless implants who have been formed using spinal cord implants using a shaped device. clock that obey the user's voice. The results of the research were published in the journal Nature and Nature Neuroscience.
Spinal cord injury interrupts the relationship between brain and spinal neurons causing motor and sensory deficiencies in the body parts that are injured, sometimes causing paralysis. In most cases, there are still links between brain and motor neurons in the spinal cord during injury, but it may not be enough for a person to move. The Courtine team uses electrical stimulation to get more excitement in these motor neurons, boosting signals from remaining relationships.
It was first determined to determine which areas of the spinal cord contributed to the movements required for each movement, such as bending the hip or extending the ankle. Then, three people were implanted with electrical stimuli that had deteriorated due to various spinal cord injuries in their legs.
After discovering which parts of the spinal cord participated during the walk, the team was able to program a series of electrical impulses that could stimulate the spinal cord at the right time and spot to facilitate these movements.
This electrical stimulation alone did not cause movement, it only worked when the participants of the study tried to move on their own. "It really works like an amplifier," said Courtine. "It's not like controlling your feet, and patients have to do it," he said, adding that only after two days of training it was almost natural that patients would guide the devices. In a week, participants were able to walk with bodies that had body mass part of it was supported.
Courtine said: "The precise timing and location of electrical stimulation is key for the patient to create the desired motion. This time-shift also causes new neural connections to grow."
In summary, electronic implants have been able to match the order of the brain, the bones and muscles of the foot.
Progress is important, but there is still a lot of experimentation, each person has a different injury, and now every implant needs to be customized.
