This electrotherapeutic device treats medical conditions such as muscle spasms and joint contractures, and provides general pain relief. It does this by offering continuous and pulsed modes to generate deep heat within body tissues. The TheraTouch DX2 features resonant auto-tuning technology that continually adjusts to provide consistent coupling, based on calculations of the patients impedance, size, and body density. This ensures maximum energy transmission, without resorting to a higher dosage, resulting in faster heating and shorter treatment times. The unique parameters afforded by Richmars exclusive Scientific Dosage Control (SDC), allow for an increased thermal effect with decreased risk.
