NEW BioMed® Fit – Russian/Interferential Unit

General Specs

Data recorded across a 1000 OHM resistance load.

Russian Therapy

The BioMed® Fit is a TRUE Russian Stimulator and Interferential handheld device. Originally developed in 1971 by the Russian Olympic team for strength and muscle mass enhancement, is now mostly used for muscle strengthening in the United States. Russian stimulation Is Not EMS (Electrical Muscle Stimulation). A Russian stimulator has a Carrier Frequency of 2500 Hz while an EMS device is around 250 Hz.

Russian provides a deeper muscle penetration providing a stronger and more complete contraction of the muscle fibers. The BioMed® Fit is programmed with 10-50-10 Russian protocol providing a TRUE Russian experience usually only found in clinical models. Other handheld Russian devices DO NOT HAVE PROTOCOLS!!

The BioMed® Fit also incorporates Interferential therapy for pain and edema reduction.

A “TRUE” Russian Stimulator has both a high frequency of 2500 Hz (50% duty cycle at 50 Hz) combined with a 10-50-10 Russian protocol.

The 10-50-10 Russian protocol is as follows:

• 10 seconds of stimulation (muscle contraction)
• 50 second rest period
• Repeating this cycle 10 times.
  • There are a total of 11 cycles (1st cycle is an Amplitude adjustment period)
  • Amplitude keys will not respond when cycle starts
  • Ramp ON = 1 sec
  • Ramp OFF = 1 sec
  • ON TIME = 10 seconds
  • OFF TIME = 48 seconds, counts down on LCD. After final cycle device beeps and shuts off.
  • Total time elapsed is 10 minutes

What is meant by 50% duty cycle at 50 Hz?

• This refers to the amount of bursts per second.
• There are 50 bursts per second.
• Each burst has a carrier frequency of 2500 Hz.

Russian Therapy

• 10-50-10 protocol
• 11 total cycles
• Symmetrical Square pulse train
• Frequency = 2500 Hz,
• Pulse Width = 250 µS
• Vpeak = 70V into 1000 Ohm Load
• Pulse Train 50% duty cycle at 50 Hz

Interferential Therapy

Interferential (IF) Therapy works by sending small electrical impulses through the skin. Interferential stimulation is characterized by two alternating current sine waves of differing frequencies that work together to produce an interferential current that is also known as a “Beat Frequency”. One of the two currents is usually held at 4000 Hz and the other can be held constant or varied over a range of 4001 to 4150 Hz. Because of the frequency, the interferential wave meets low impedance when crossing the skin to enter deep into soft tissues. The interferential currents can stimulate sensory, motor and pain fibers. These large impulse fibers interfere with the transmission of the pain messages at the spinal cord level. This deep tissue penetration stimulates parasympathetic nerve fibers for increased blood flow and edema reduction. It utilizes the low electric current to stimulate muscle nerves to achieve the symptomatic relief of chronic intractable pain, post traumatic pain and post-surgical pain. In turn, reducing or eliminating the need for most pain-related drugs.
