The Proprio Foot by Össur is a brain-controlled electric prosthetic foot that matches natural foot motion. The Proprio Foot is designed to work on a variety of ground surfaces to allow a wide range of mobility, and the motorized action of the foot requires less effort from the user to walk than a traditional prosthetic.
The device is controlled by special sensors implanted in the owner’s leg muscle. When a signal from the brain reaches the sensors, they relay the signal to the Proprio Foot to make the appropriate action.
