Ever heard of a mind-controlled prosthetic arm? Well, incredible as it sounds, such a thing actually exists, and has been trialled on a patient named Johan Baggerman in the Netherlands. According to Engadget, Baggerman is the first patient ever to get a click-on prosthetic arm that can be controlled via the mind. The arm has a direct connection to the bone and so, cancels the need for a prosthesis socket. But, what exactly does ‘controlled via the mind’ mean here?
The arm’s mind control aspect exists in the fact that the patient’s nerves are connected to the socket, while there’s also a special Bluetooth bracelet to receive signals. This means that now, the nerves that are used to control the patient’s hand muscles, are connected to the upper arm stump. Made possible through three surgeries, this amplifies the neural signals involved, which helps when the patient is healed.
