1. A method for determining a portion of locomotion and a phase of locomotion portion in view of controlling an actuated prosthesis in real time, the method comprising;

  • providing a plurality of main artificial proprioceptors;

    receiving a data signal from each of the main artificial proprioceptors;

    obtaining a first and a second derivative signal of at least some of the data signals;

    obtaining a third derivative signal for at least one of the data signals;

    using a set of a first state machines to select one state among a plurality of possible states for each main artificial proprioceptor with the corresponding data and derivative signals;

    generating the phase of locomotion portion using the states of the main artificial proprioceptors; and

    using a second state machine to select the portion of locomotion among a plurality of possible portions of locomotion using events associated to the data signals.
