Abstract
In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient'"'"'s spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications. In particular embodiments, aspects of the foregoing modulation therapies may be implemented by systems and devices that have simplified functionalities.
