ABSTRACT:
The assembly comprises a band, mountable on the leg, carrying all of the components of the assembly to provide a self-contained unit. The components comprise: electrodes for stimulating a leg nerve; a V-shaped plate for conforming with the leg's tibia to reproducibly position the band so that the electrodes are located over the nerve; a tilt sensor for measuring the angular position of the lower leg; a control circuit for processing the sensor signal information and emitting pulses through the electrodes to stimulate the leg in response to phases of body movement; and a battery for supplying power to the tilt sensor, control circuit and stimulator. By comparing the assembly's stimulation states against a known template defining optimal stimulation states, stimulation threshold parameters can be fine tuned without the need for repeated trial and error testing by the user.
