This comfort therapy unit is the new benchmark in Electro Therapy. The unit works with a threedimensional interference current generated through the superposition of three middlefrequency currents. It can be used as an Electro Therapy device, ultrasound therapeutic device and for the combination of electrical stimulus current with ultrasound. Features Three-dimensional stimulation effect Multi-site stimulation effect intensity dynamics Dynamic behavior of stimulation site coupled with endogenous exogenous stimulation shifting.
