This SD-730 interferential stimulator device is used for the symptomatic relief and management of chronic (long-term) intractable pain. Interferential therapy is based on the effect of low-frequency stimulation as in the biological frequency range. The low Interferential current is the result of two interacting medium frequency currents produced by Interference SD-730. The treatment can proceed with four or two electrodes. Features: *Would not result in over-excitation of nervous and muscular tissues *Low battery indicator *Mild transcutaneous nerve stimulation would not result in discomforts and pain. More current output is acceptable *No electrolysis will occur and this therapy can avoid skin injuries *Significant effect of medium frequency can accept more electric current during treatment Currency: USD Unit Price: Quantity: Delivery:
