Briefly describe the difference between interference current method and modulated intermediate frequency electrotherapy.

The difference between interference current method and modulated intermediate frequency electrotherapy lies in their different electromagnetic frequencies. According to relevant data, interference electrotherapy refers to a kind of electrotherapy that inputs two groups of currents with different frequencies into specific parts of human body, and forms a new current through the difference of two groups of current frequencies, so as to achieve the purpose of treatment. Modulated medium-frequency electrotherapy is a method that the amplitude and frequency of current change with the amplitude and frequency of low-frequency current after it is modulated by low-frequency current. The method of treating diseases with this current is called modulated medium-frequency electrotherapy. The current generation method and electromagnetic frequency used for treatment are different.
