The Power of Powered Prosthetic Devices (IMAGE) North Carolina State University Caption This image shows the study participant performing a squatting activity with different prosthetic devices. When the participant used his daily prosthesis (left picture) he had a limited range of motion and had to bend his back significantly to lift objects off the ground. When using a neural controlled prosthetic ankle (right picture) he was able to voluntarily control his prosthesis ankle joint force and angle and keep a healthy posture while lifting weight from the ground.
