Finding a way to help a paralyzed person can still be grasped

Scientists on April 18 reported using electrodes implanted in the lab brains so they could pick up balls with a paralyzed hand.

This is an encouraging result for those with spinal injuries.

Researcher Lee Miller at Northwestern University in Chicago, USA, says monkeys are implanted electrodes in the brain and hands can grasp and move balls regardless of whether their hands have been numbed.

He confirmed that this implant allows the brain to directly direct muscles without having to go through the spinal cord.

The connection from the brain to these muscles could one day be used to help paralyzed patients with spinal cord injuries to participate in daily activities and become more independent.

However, he admits there are differences between anesthesia monkeys and paralyzed subjects because the muscles of these subjects weaken over time and no longer work.

He added that scientists have come very close to the stage of using this new technology for humans, but first have to overcome some technical problems.

One of them is the type of electrode used with a short life span and must be replaced after two or three years.

Human trials can be performed in 5 years.
