Abstract:
1. An apparatus comprising: at least one memory; at least one controller, coupled to the memory, programmed to perform operations comprising: sensing a first physical orientation between a patient's first and second appendage portions, which couple together via a joint, during a baseline state; sensing a second physical orientation between the first and second appendage portions during a non-baseline state; determining an orientation differential between the first and second physical orientations; determining a current stimulation characteristic, corresponding to first current, based on the orientation differential; and stimulating at least one of the joint, first appendage portion, and second appendage portion with the first current in a hysteretic closed loop relationship relating the current stimulation characteristic to the orientation differential wherein the stimulating with the first current in the closed loop relationship includes adjusting the current stimulation characteristic in proportion to the orientation differential.
