Dr. Vazharovs method combines conventional electrotherapy with cryotherapy, thus allowing delivery of significantly larger medication doses to the targeted body part. The active electrode is a suitably shaped ice block formed by freezing the drug solution which is to be administered. The temperature of the ice electrode is controlled using the thermoprobe - it must be apr. -5 C to begin therapy (colder than that can cause skin injury). During therapy, the ice electrode is slowly moved over the treated area. Dr. Vazharovs method has been developed during the 1970s and clinically applied since the early 1980s with an excellent success record.
