Regain Hand Motion With the Hand of Hope

The Hand of Hope is a therapeutic rehabilitation device that helps patients with hand injuries to re-learn how to move these body parts. To accomplish this, the impaired hand is attached to a robotic hand.

Additionally, two electromyography (EMG) sensors are placed on the extensor and flexor muscles of the patient’s arm. They transform the intention to move the hand into signals that drive the robotic hand and, in consequence, the real hand. The speed of this process allows the user to re-connect the movement to the initial intention in the brain.

In order to facilitate rehabilitation and make it more pleasant, computer games are used to learn specific movements, like opening the hand and closing it to grasp an object.
