Interferential Therapy (IF) uses the strong physiological effects of low frequency electrical stimulation of muscle and nerve tissues without the associated painful and unpleasant side effects of such stimulation. To produce low frequency effects at sufficient intensity at depth, most patients experience discomfort in the superficial tissues. This is due to the resistance of the skin being inversely proportional to the frequency of the stimulation. The skin impedance at 50 Hz is approximately 3200 ohms while at 4000Hz it is reduced to about 40 ohms. This higher frequency passes more easily through the skin, requiring less electrical energy input to reach deeper tissue, causing less discomfort.
Low amplitude current delivered through the skin with higher amplitude current delivered to deeper tissue provides more comfortable treatments than other wave forms. Easy-to-operate controls with no complex programming. The IF100 is an interferential stimulation device for symptomatic relief and management of chronic pain and/or as adjunctive treatment in the management of post surgical and post traumatic acute pain. Four frequency options. Sliding cover helps protect the controls from accidental movement. Includes carrying case, battery, adapter, lead wires and instructions.
