The fake hand will feel like a real hand thanks to this new system

False limbs have been greatly improved over the past half century. From just being rigid artificial parts, today's technological breakthroughs can create fake limbs that feel real and controlled by the brain.

Of course, as prostheses, they still cannot help users feel like real limbs. But according to BGR news page, this problem is about to be solved, when scientists have developed a solution that allows fake users to perceive objects intuitively, from there, can hold, grasp, control everything without even looking at them as usual. This study, published in the journal Science Translational Medicine, is a big step in creating prosthetic limbs with full ability to function as a true genus.

Specifically, this study focuses on the ability to feel slight vibrations near the limb area that have been amputated to "mimic" the sensations of natural muscle movement . These feelings are what inform our brains what the limbs are doing even when we don't see them. In the current period, scientists only initially tested this system in patients using artificial hands.

The test subjects of the researchers were three patients who had been involved in transplantation of prosthetic limbs capable of controlling through the brain. This involves reorienting the nerves in the left arm to allow the prosthetic hand to receive signals from the brain and "translate" the signal into corresponding movements.

Patients are equipped with small accessories that are able to activate vibratory feedback when they move the prosthetic arm, then proceed with some manipulation to check how this system affects the ability their controller. The results show that this artificial sensory feedback system is extremely useful, and the researchers realized that it actually improved the patient's ability to use prosthetics without them having to look at the object. I want to hold. When viewed directly, patients even perform much more precise operations than usual.

According to research author Paul Marasco from Cleveland Clinic, the team tested the artificial arms capable of touching, moving and controlling through the motor at the same time, when the disease Thinking about moving the arm, they will feel it moving in the air, and when they take something, they will feel the same feeling as the previous feeling on the real arm. . In the future, they will test the next step: integrating all of the above into a complete system.
