The myoelectric control of upper limb prostheses from surface EMG signals is characterized by the ease of data collection and by being non-invasive. Multiple functions of a prosthesis can be activated from the signals generated by a voluntary muscle contraction. In this work, we present a system that activates four functions of a hand prosthesis with two EMG channels by means of a command strategy based on the maximum voluntary contraction (MVC). Experiments were performed on five healthy subjects and one amputee to evaluate the feasibility of this strategy. The results showed a fluid and intuitive strategy, justified by an accurate performance of the subjects controlling the prosthetic functions.
