What is inferentail?

Answer 1

Interferential is a type of electrical therapeutic modality often used by chiropractors or physical therapists.  

Interferential therapy has been around since the 1950s and involves the use of 4 electrode pads to create 2 medium frequency currents that cross within the body and the formation of a third current that radiates from the midpoint of those pads & from the inside of the body out.  This third frequency is the "Beat frequency" and is the therapeutic frequency.  

This therapy can be used to decrease pain, decrease edema (swelling), or break muscle spasm.  In acute patients the settings are normally set to below the patient's threshold of tolerance (submitis dosis), in subacute or chronic patients the settings are often set to just at the patient's threshold tolerance (dosis mitis).  This therapy is often applied for 10-20 minutes, however the time period may vary based on the intentions of your health care provider.
