1. A method for treatment of pain, comprising:

  • generating, by a power supply device, a non-pulsed electrical current comprising a frequency between 10 Hz and 2000 Hz and a rise time from 0 to a peak amplitude of at least 10 μ

    s;

    supplying the non-pulsed electrical current to at least two electrodes at diametrically opposed locations about the peripheral nerve;

    applying, by the at least two electrodes, the non-pulsed electrical current through the peripheral nerve in a direction substantially transverse to a longitudinal axis of the peripheral nerve; and

    inhibiting conduction of C-fibers in the peripheral nerve based on the application of the non-pulsed electrical current to prevent the transmission of pain signals,wherein motor nerve fibers and higher-sensory nerve fibers in the peripheral nerve are not substantially activated based on the application of the non-pulsed electrical current.
