Cathy Hutchinson is a tetraplegic. She has not been able to move her arms, legs or speak since suffering a stroke nearly fifteen years ago. Recently, she learned how to control a robotic arm using her thoughts. She now can use brain activity to serve herself a drink.

The American woman is one of two people who took part in a research project known as BrainGate2. The researchers have spent years studying how to help people who are paralyzed regain movement in their arms and legs.
