Abstract

Disclosed are prosthetic systems comprising a powered knee upper leg prosthesis and a volitional controller configured to provide control of the prosthesis to the user. The prosthetic system may be configured to enable a user to climb a set of stairs. The prosthetic system may be activated by the activation of an EMG signal source, such as the biceps femoris muscle of the upper leg. The volitional controller of the prosthetic system may be further configured to receive a ground state signal and/or an IMU signal to determine a target knee torque for operating the powered knee of the prosthesis.
