Abstract
A system and method for providing percutaneous electrical nerve stimulation therapy to a patient renders the therapy effective for a large patient population and a broad range of patient conditions. The method includes the steps of inserting an electrode into the patient and applying an electrical signal between the electrode and the patient's body at a plurality of frequencies that automatically vary over the range of frequencies. The range of frequencies may have a minimum frequency of at most about 20 Hz and a maximum frequency of at least about 40 Hz. In addition, the electrical signal may be compensated for changes in frequency. The compensation may be in the form of amplitude adjustment or pulse with adjustment to provide effective signal energy over the entire range of applied frequencies.
