There are electric hands, and there are body-powered hook devices, but what happens when you want to combine both? The answer is electric hook-type devices. These can, for example, be controlled by muscle contractions in the same way as myoelectric hands, while allowing the same sort of pinch and grasp movements as body-powered hooks and prehensors. They can be interchangeable with electric hands, giving users more options to draw on in their daily activities.

The options available at this time are:
