Interferential current stimulation is a form of therapeutic transcutaneous (skin) electrical stimulation of nerve and surrounding tissues. Two medium frequency biphasic pulsed currents are applied simultaneously to a targeted body region, so that the two currents superimpose to produce a new low frequency current deep within the tissue. Interferential stimulators use simultaneous medium frequency currents to overcome high skin and subcutaneous tissue impedance. Interferential stimulation has been investigated as a technique to reduce pain, improve range of motion or promote local healing following various tissue injuries.
Advantages Since Interferential Therapy has been in use for many years, its effectiveness is well documented. Studies have shown that patients using Interferential Therapy after surgery develop fewer post-op complications than those relying solely on narcotics for pain relief. Interferential stimulation does not cause respiratory depression. Interferential Therapy aids in circulation, increasing the recovery time for patients. Multiple treatments at home or work will typically speed the patient's recovery and allow earlier resumption of their normal lifestyle.
Commonly Asked Questions in Regards to Interferential Therapy:
Are Interferential devices safe? YES. Although the thought of electrical impulses being sent into the body may seem frightening at first, all you really feel is a slight vibrating sensation. Unlike many drugs, Interferential devices have no known side effects.
Who cannot use an Interferential device? Individuals with a pacemaker or patients who are pregnant should not use an Interferential device. Consult your doctor or clinician first.
Will an Interferential device work for me? Interferential Therapy has been used extensively for managing post-surgical, post-traumatic acute pain, edema and inflammation reduction.
