Interferrential and Russian Stim


Interferential stimulation (IFS) uses interfering electrical currents to regulate blood flow, reduce pain, decrease edema, relieve muscle spasms, and strengthen muscle tissue. Used in the treatment of contusions, sprains, strains, and a variety of other injuries, IFS uses two generators and four electrodes to produce two currents that act on the tissues simultaneously. The patient is connected to the generators through the attachment of pads, or electrodes, that are connected to the units by wires. The four pads are placed in a square pattern in which two pairs of opposing pads will each produce a current that will intersect with each other at a midpoint, causing interference. This interference then causes the currents to spread from the point of intersection to the surrounding tissues. The patient should feel only a slight vibrating sensation beneath and between the pads. IFS may also be used in conjunction with heat packs or ice packs.

Settings used for IFS should follow the physician, therapist, or manufacturer's guidelines. In general, the currents used for IFS range from "I to 10 Hz. The pairs of pads should differ in amplitude by +1 Hz. Average treatment times are 15 minutes. IFS therapy may be done once a week or several times a a day, depending on the physician or therapist's recommendations. IFS should not be used over carotid arteries or high fluid areas, for undiagnosed pain, or for prolonged periods. Individuals with a pacemaker and women who are pregnant should not use an interferential device without consulting a physician.

Russian Stim

Russian Stimulation is a specific form of electro-stimulation with a Symmetrical Biphasic Square waveform produced by dividing a 2500 Hz carrier frequency into 50 Hz packets . Originally developed by the Russian Olympic team for muscle mass enhancement, is now often used for muscle strengthening, muscle spasms & Edema reduction in the United States. Russian Muscle stimulation is similar to interferential. It is designed to stimulate motor nerves. However, the high frequency of 2500 Hz allows for deeper muscle penetration and a more complete/stronger contraction of the muscle fibers.
