Scientists develop mechanical prostheses that are implanted with bones and controlled by the brain.

Release date: 2016-01-18

Scientists at Johns Hopkins University in the United States have recently developed a brain-controlled mechanical prosthetic arm that is attached to an implant directly inserted into the bone at the end of the amputation, followed by a nerve redistribution operation to achieve direct control of the prosthetic movement. This prosthetic can be applied to disabled soldiers and ordinary amputees.

The researchers tested the brain-controlled prosthetic arm on amputated patients and have now confirmed that the patient can simply move the robotic arm and grab a smaller object. The amputated man in the picture is Johnny Matheny, who lost his arm in the 2008 cancer and then began experimenting with innovative robotic arms.

This new prosthetic system replaces the slings required for modular prosthetic (MPL) work, which can cause discomfort to the patient for extended periods of time. Masini has been able to recover many natural movements since wearing this prosthetic limb. In order for this prosthetic to work like a modular prosthetic, the patient must undergo muscle regeneration beforehand.

At first the researchers planned to operate cautiously after Masini's prosthetic installation, but immediately after the prosthetic was installed, he was able to move the robotic arm.

Masini can use the prosthetic to move the mechanical finger, grab the object, and achieve some degree of mechanical wrist activity.
