Abstract
A spinal cord modulation system is disclosed. While in one embodiment the system is used for the treatment of pain, other embodiments are also provided. In particular embodiments, the spinal cord modulation system generates and delivers an electrical therapy signal at a frequency in the range of from about 1.5 kHz to about 100 kHz to address pain without creating unwanted sensory and/or motor side effects. The system may further include various signal delivery devices to deliver the therapy signal to a patient'"'"'s spinal cord region.
