The device allows the wearer to flex, point, and rotate the foot of the prosthetic using their thoughts alone, leading to a more natural gait, improved stability on stairs and uneven terrain, and a 41% increase in speed compared with a traditional prosthetic.
The bionic leg works by reading activity in the patient's residual leg muscles, using these signals to control an electrically powered ankle, enabling brain control for natural movement.
Patients reported less pain, muscle atrophy, and felt the prosthetic limb was part of their body, showcasing the benefits of brain-controlled bionic legs over traditional prosthetics.
