IF sine wave (Digital Interferential)


    •  Package Includes: Device, batteries, lead wires, 1 pack of 4 electrodes, carrying case and users manual.
    • Crossing of two electrical medium, independent frequencies.Stimulate large impulse fibers.
    • Deep tissue penetration can be adjusted
    • Dual Channel device with the ability to adjust each channel.


This type of stimulation is characterized by the crossing of two electrical medium, independent frequencies that work together to effectively stimulate large impulse fibers. These frequencies interfere with the transmission of pain messages at the spinal cord level. Because of the frequency, the Interferential wave meets low impedance when crossing the skin to enter the underlying tissue. This deep tissue penetration can be adjusted to stimulate parasympathetic nerve fibers for increased blood flow. Interferential Stimulation differs from TENS because it allows a deeper penetration of the tissue with more comfort (compliance) and increased circulation.
