The therapy is meant to boost the body's natural process of responding to pain, by increasing circulation thus producing hormones that promote healing. IFT delivers intermittent pulses to stimulate surface nerves and block the pain signal, by delivering continuous deep stimulation into the affected tissue. IFT relieves pain, increases circulation, decreases edema, and stimulates the muscles. A frequency of 100Hz may stimulate the large diameter A-beta fibers, which have an effect on the pain gate, and inhibit the transmission of small-diameter nociceptive traffic ( C and A-delta fiber), which effectively closes the gait to painful impulses. Interferential current Increases the circulation of blood thus reducing swelling, by washing away the chemicals that stimulate the nociceptive nerve endings.A frequency between 1 and 100 Hz is used to contract the normal innervated muscles. Different types of frequencies cause different contractions, a low frequency, causes a twitch, a frequency between 5 and 20 Hz causes a partial tetany contraction and a frequency from 30 to 100 Hz causes a tetanic contraction. IFT also helps to reduce edema 100Hz frequency promotes vasodilation, thus decreasing edema. And a frequency of 10 Hz activates the musculoskeletal pump, used to promote venous and lymphatic return causing a reduction of edema. The neurons that make up the autonomic nervous system, are small and poorly myelinated like the A? and C fibers of the peripheral nervous system and to stimulate the autonomic nervous system, lower frequencies are utilized to increase the blood flow.................................................................WHAT ARE THE TREATMENT PARAMETERS OF INTERFERENTIAL THERAPY (IFT)?The effect of IFT depends upon:FrequencyIntensity of currentElectrode placementFrequency100-150Hz constant or 90-100Hz rhythmic: These frequencies are useful for pain relief, IFT acts on large myelinated fibers in the dorsal horn, blocking off small pain fibers. The higher frequencies have a triggering effect on the endogenous opiates in the mid-brain which inhibit pain.0-10Hz rhythmic or 10- 50Hz rhythmic: These frequencies are useful for muscle stimulation. They produce stimulation of deep, normally innervated muscle tissue with little sensory stimulation. As the frequency increases the contraction changes from a twitch to a tetanic contraction.0-100Hz rhythmic: The range of frequencies produces vasodilatation. This is stimulation and relaxation of vessel walls, giving a sinusoidal effect.Intensity of currentThe current is increased till the patient feels tingling, further as accommodation occurs the intensity is increased slowly to the point of muscle stimulation. The duration of treatment varies between 10 - 20 minutes.Electrode placementThe patient is placed in a comfortable position and the skin is prepared for the treatment. The skin is cleaned, in case of any skin lesion, the area is insulated with petroleum jelly. Vacuum electrodes or pad electrodes are placed accurately at the treatment site and the two pairs of electrodes are positioned so that the crossing point of the two currents is over or within the lesion.''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
