Abstract

A method and apparatus for diagnosing and treating neural dysfunction is disclosed, which comprises taking the energy output from a high frequency generator module and delivering this energy as in a pulsed manner to a treatment electrode. In one exemplary embodiment, a temperature set point is utilized, and the pulses are modified to limit the energy delivered such that the temperature is limited. One exemplary method of modifying pulses includes reducing the amplitude of the pulses. Another exemplary method of modifying pulses includes reducing pulse width. Another exemplary embodiment of modifying pulses includes only delivering full width and amplitude pulses.
