1. A device for use with a plurality of electrodes, and one or more sensors, the device comprising:

  • a stimulation assembly connectable to the plurality of electrodes, wherein the plurality of electrodes are configured to connect to a spinal cord at a location below a lesion of the spinal cord;

    the stimulation assembly being configured to deliver stimulation to selected ones of the plurality of electrodes when the stimulation assembly is connected to the plurality of electrodes;

    a sensor interface connectable to the one or more sensors, the sensor interface being configured to receive signals from the one or more sensors when the sensor interface is connected to the one or more sensors, wherein the one or more sensors are selected from an electromyography sensor, an evoked potential sensor, a joint angle sensor, a flex sensor, an accelerometer, a gyroscope sensor, a flow sensor, a pressure sensor, a load sensor, a temperature sensor, or a combination thereof;

    at least one processor connected to both the stimulation assembly and the sensor interface, the at least one processor being configured to direct the stimulation assembly to deliver at least one complex stimulation pattern to the selected ones of the plurality of electrodes, and to receive the signals from the sensor interface, the at least one processor being further configured to modify the at least one complex stimulation pattern by performing a machine learning method implementing a Gaussian Process Optimization operable to determine the stimulation parameters delivered by the stimulation assembly based on the signals received from the sensor interface.
