Abstract: A powered prosthesis for providing volitional control of knee flexion during swing is configured to (i) determine that a swing phase has initiated, (ii) obtain a thigh angle based on the sensor data associated with a residual limb of a user, (iii) based on a time elapsed since initiation of the swing phase, and based on the thigh angle, determine a desired maximum knee flexion angle, (iv) during the swing phase, continuously update the desired maximum knee flexion angle using subsequent measurements of thigh angle and time elapsed since initiation of the swing phase, and (v) output a signal configured to cause actuation of the knee joint based on the desired maximum knee flexion angle.
