1. A functional electrical stimulator for use on a body limb, comprising:

  • a band, mountable on the limb, for carrying stimulator components;

    cathode and anode electrodes carried by the band in a fixed condition;

    means, carried by the band, for reproducibly positioning the band so that the electrodes are located at specified stimulation locations;

    sensor means, carried by the band in a fixed condition, for measuring the angular position of the limb during movement and emitting sensor signals indicative thereof;

    control circuit means, carried by the band and connected with the sensor means and electrodes, for receiving the sensor signals, processing the sensor signals to establish values indicative of the changing angularity of the limb as a function of time and to compare the established values with predetermined adjustable angular ON and OFF and time threshold values for initiating and terminating the emission of pulses through the electrodes when the established values reach the angular ON and OFF and time threshold values, to stimulate the limb; and

    battery means carried by the band and connected with the sensor means and control circuit means, for supplying electrical power to them.
