For years, the presence of "ghost participants" has been a mystery in amphibians, attracting the attention of scientists around the world. There was a moment that was considered as a psychological phenomenon, fruits mourning for the lost limbs. However, over time it has been discovered that ampute handheld card Created by measuring brain activity in patients, is very similar to those who have not lost that part of the body. In addition, some studies have shown that there is a "movement" of amputated hands brain activity amputees
So what if all this would be used to create prostheses that move in response to movements of amputated members? This question was asked by a team of French scientists, from the Institut des Systèmes Intelligents et Robotics, Aix-Marseille University and the Institut Régional de Médecine Physique et Repossession. The answer was a prosthesis driven phantom limb movements, therefore, patients, as explained in a study published in 2009 Bioengineering and biotechnology boundaries, not required No surgery or previous training.
When the phantom limb ceases to be a ghost
Roughly 75% of ampoule is the ability to "move" your phantom limbs. These movements cause contractions develop in the muscle of the stomach which are not connected to the joints before amputation. The result is similar surgical re-joining this is done to put some dentures, but in this case it happens spontaneously and without surgery.

This led to the development of these French researchers algorithm which recognizes the muscle activity that arose before the phantom limb movement and multiply it in the prosthetic. At the moment, they have done two tests patients with intramuscular amputation and as you can see in this video, the results are very encouraging. None of the cases had a prostitute placed on a loop, but instead near him. Even patients manage it Hold and release objects as you wishin just a few minutes Getting to know the device.
This study is very positive, mainly for two reasons. On the one hand, this may be due to the initiation of a new type of prosthetic. easier to use. In many cases, those who need training are ultimately desperate for patients who may become unsatisfied and give up before you learn it. On the other hand, the results support other scientists who are convinced that they are neurological explanation about the look of the ghost members and it should be more closely researchedto get applications as interesting and beneficial as those obtained by these French researchers.
