A method for immobilization of a human or animal target passes a current through a circuit that includes tissue of the target. The current causes pain compliance or interferes with skeletal muscle control by the target. The method includes in any practical order: (a) generating a first compliance signal of the current, the first compliance signal having a first maximum amplitude; and (b) generating a second compliance signal of the current, the second compliance signal having a second maximum amplitude. The absolute value of the second maximum amplitude is less than the absolute value of the first maximum amplitude. A system that performs such a method may include a processor, a signal generator, and electrodes or terminals for forming the circuit through tissue of the target. Systems, according to various aspects of the present invention, may include stun guns, dart weapons, electronic control devices, electrified projectiles, and mines, to name a few applications.
