Abstract: A device (10, 50, 60, 70, 80, 90) is used to apply an electric pulse or spike to a patient to treat the patient. The device can have a series of preset treatments programmed therein. A user can select a treatment from menus displayed on a display (100). The impedance of the skin and underlying tissue to be treated can be measured prior to the treatment to locate active areas on the skin for treatment. A variety of probes can be used with the device, with the device automatically detecting the type of probe attached. Multiple electrodes can be used on the probe, which allows the active areas in contact with the probe to be identified prior to treatment to allow the treatment to concentrate on the active areas.
