Product Description

The “LG-UIF” is our 2 Channel Digital Interferential Powered Unit that will dramatically help relieve your pain related to many many conditions. This unit is portable and also has an AC Adapter, which makes it extremely convenient to use at home and while traveling.

The “LG-UIF” Interferential Unit goes penetrates deep into the tissue to help acheive maximum results and reductions on the pain scale. Interferential Therapy aids in circulation, decreasing the recovery time for patients. Multiple treatments at home or work with the “LG-UIF” will typically speed the patient’s recovery and allow earlier resumption of their normal lifestyle.

Conventional TENS and Neuromuscular Stimulators deliver most of the stimulation directly under the electrodes. Interferential Stimulator Current perfuses to greater depths and over a larger volume of tissue than other forms of electrical therapy.

Common uses:

Pre and post-orthopedic surgery, joint injury syndrome, cumulative trauma disorders, increasing circulation and pain control of various origins. Interferential Therapy is used in the treatment of circulatory disorders, range of motion, edema and muscle spasms. Post-op patients will use the device 3 times a day for 15 minutes over a period of 14 – 30 days.

Interferential Units helps control pain and speeds the healing process by delivering small pulses of electrical current to an injury through electrodes that pass current through the skin and stimulate underlying nerves producing a mild, tingling sensation to provide relief from chronic and acute pain. Interferential is used for very localized areas where deep current for pain control or increased circulation is needed.

How does Interferential therapy differ from TENS?

Interferential differs from conventional Muscular stimulation and TENS in that it delivers concentrated stimulation deep into the affected tissue. Interferential exploits the interference of two separately generated sinusoidal currents applied to the body simultaneously. It is a low frequency current 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 of this frequency is usually 1-250 Hz. The body itself produces low frequency currents between 1 and 256 Hz.

These currents are produced across the cell membranes by ionic exchange, and they will vary depending upon the tissue involved. By using frequencies in this range, different systems within the body can be stimulated.

Interferential electrical stimulation’s is a unique way of effectively delivering therapeutic frequencies to tissue. Conventional TENS and Neuromuscular stimulators use discrete electrical pulses delivered at low frequencies of 2-160 Hz per second. However, Interferential stimulators use a fixed carrier frequency of 4,000 Hz per second and also a second adjustable frequency of 4,001-4,400 Hz per second.

When the fixed and adjustable frequencies combine (heterodyne), they produce the desired signal frequency (Interference frequency). Interferential stimulation is concentrated at the point of intersection between the electrodes. This concentration occurs deep in the tissues as well as at the surface of the skin.

Conventional TENS and Neuromuscular stimulators deliver most of the stimulation directly under the electrodes. Thus, with Interferential Stimulators, current perfuses to greater depths and over a larger volume of tissue than other forms of electrical therapy. When current is applied to the skin, capacitive skin resistance decreases as pulse frequency increases.’ For example, at a frequency of 4,000 Hz (Interferential unit) capacitive skin resistance is eighty (80) times lower than with a frequency of 50 Hz (in the TENS range). Thus, Interferential current crosses the skin with greater ease and with less stimulation of cutaneous nociceptors allowing greater patient comfort during electrical stimulation.

In addition, because medium-frequency (Interferential) current is tolerated better by the skin, the dosage can be increased, thus improving the ability of the Interferential current to permeate tissues and allowing easier access to deep structures. This explains why Interferential current may be most suitable for treating patients with deep pain, for promoting osteogenesis in delayed and nonunion fractures and in pseudothrosis, for stimulating deep skeletal muscle to augment the muscle pump mechanism in venous insufficiency, and for depressing the activity of certain cervical and lumbosacral sympathetic ganglia in patients with increased arterial constrictor tone.


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.

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. It has been used successfully for a wide variety of procedures such as:
