Abstract

Systems, devices and methods for control of a prosthetic or orthotic device (POD) based on electromyography (EMG) signals are described. The POD may be a lower or upper limb POD having one or more joints. One or more EMG sensors may detect the EMG signals. The EMG sensors may be external, subcutaneous, intraperitoneal, epimysial, intramuscular, or other types. Control of the POD may be based on EMG and non-EMG signals, such as velocity, acceleration, position, force, etc. Voluntary and/or automatic control may be implemented, for example with voluntary muscle contractions and/or data based on velocity, acceleration, position, force, etc. In some embodiments, the neutral position of an ankle POD is adjusted based on EMG signals.
