IF-4000 Interferential Stimulator

The model 4000 IF (Interferential) stimulator device is used to treat symptomatic relief and management of chronic pain and/or as adjunctive treatment in the management of post-surgical and post-traumatic acute pain. It is a low frequency treatment that uses two medium frequency currents which "interfere" with each other to produce a beat frequency that the body recognizes as a low frequency energy source. The range is usually 1-250 Hz. The body produces frequency currents between 1-256 Hz. The major use of interferential therapy is to accelerate the inflammatory or healing rate. So almost any condition can be treated where inflammation is a problem. This is a dual channel unit, which allows you to use up to four electrodes at a time (two electrodes per channel).
