A neuromodulation system and method includes delivering first electrical modulation energy to a patient through a timing channel at a relatively high energy level (e.g., at a frequency in the range of 2 KHz-50 KHz) during a first time period in accordance with a stored modulation energy delivery schedule, delivering second electrical modulation energy to the patient through the same timing channel at a relatively low energy level (e.g., at a frequency in the range of 2 Hz to 1500 Hz) during a second time period in accordance with the stored modulation energy delivery schedule.
