Abstract: A portable pain treatment unit includes: a first pulse generator configured to deliver pulses in a frequency range typical for interferential treatment; a second pulse generator configured to deliver pulses in the frequency range for transcutaneous electrical nerve stimulator (TENS) treatment; electrodes operatively connected with the first and second pulse generators that are configured for application to a treatment area; and a power source operatively connected to the first and second pulse generators. A device of this configuration enables the patient to receive either IF or TENS treatment at a location of his/her choosing rather than being forced to receive IF treatment in a clinical setting.

Abstract: A method of treating wounds includes the step of applying UVC radiation to the wound for a time and at a proximity and intensity sufficient to have a bacteriocidal effect. The method is particularly effective when carried out with a UVC lamp having an intensity of between 5 and 20 &mgr;W/cm2, with a duration of between about 5 seconds and 1 minute and a proximity to the wound of between about ¼ and 3 inches from the wound being preferred. It has been observed that such application of UVC radiation can kill up to 100 percent of the microorganisms present in a wound, thereby enabling the wound to heal free of infection.
