What is a high-frequency current?
high-fre·quen·cy cur·rent an alternating electric current having a frequency of 10,000 or more cycles per second; it produces no muscular contractions and does not affect the sensory nerves.
What is the frequency of low frequency current?
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz. Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave.
What is IFC therapy?
Interferential current therapy (ICT, or sometimes IFC) is the most common type of electrical muscle stimulation used to treat chronic pain resulting from surgery, injury or trauma. The end goal for using ICT as part of a physical therapy or rehab program is to relieve pain and help patients heal faster.
How does high frequency current work?
High frequency creates a circulation rush in the area and helps your current under eye product penetrate deeper into the skin tissue. The application of high frequency can be very effective at fading dark under eye circles resulting in a fresher, brighter, more youthful looking appearance.
What is the frequency range for medium frequency current?
Medium frequency
| Frequency range | 0.3 to 3 MHz |
|---|---|
| Wavelength range | 1000 to 100 m |
What is the frequency range for medium frequency?
300-3000 kHz
Medium Frequency (MF): 300-3000 kHz Because medium frequencies afford stable transmission of radio waves over long distances, they are used primarily for medium wave broadcasting (AM radio), ship communications, LORAN (radio navigation), and other applications.
What type of current is IFC?
Interferential current therapy (IFC) is based on summation of 2 alternating current signals of slightly different frequency. The resultant current consists of a cyclical modulation of amplitude, based on the difference in frequency between the 2 signals.
What is difference between IFC and TENS?
How Does IFC Differ From TENS? TENS delivers low-frequency current across the surface of the skin, while IFC delivers a higher frequency current that penetrates deeper into the tissue with less discomfort.
What is a IFC unit?
Inferential current (IFC) IFC delivers current to deep-seated structures through an amplitude-modulated interference wave typically with the use of four electrodes (Kitchen, 2001).
