This multi-interferential therapy device provides bigger, deeper stimulation through the use of two groups of current that are in different positions but have the same amplitude modulation. This forms an interferential therapy field inside the patient's body. It is ideal for stimulating motor nerves, relieving pain, promoting bone fracture recovery, and increasing the flow of blood. The device is indicated for sciatica, knee and chronic arthritis, and other body pains that respond to physical therapy.
