Systems for treating a movement disorder include a system control unit configured to be implanted at least partially within a patient and to generate at least one stimulus in accordance with one or more stimulation parameters adjusted to treat the movement disorder. The systems further include a programmable memory unit in communication with the system control unit and programmed to store the one or more stimulation parameters to at least partially define the stimulus such that the stimulus is configured to treat the movement disorder. A means for applying the stimulus to one or more stimulation sites within the patient is operably connected to the system control unit.
