IFT which stands for Interferential Therapy is one of the kinds of electrotherapy used for the supervision of pain. The principle of interferential therapy is to reason two medium incidence currents of somewhat different frequencies to delay with one another. For instance, if circuit A transmits a current with an incidence of 4000Hz and Circuit B carries a current with an incidence of 3980 Hz, then the low frequency fashioned will be 20 Hz and this incidence is very useful in pain modulation. It is essentially used for the treatment of Chronic, Post Traumatic, and Post-surgical care. The rudimentary principle includes the use of effects of low incidences (<250pps) without sore or unpleasant side effects. The major benefit of IFT treatment given on IFT machine Suppliers is that it creates effects in the tissue, precisely where obligatory without needless and painful skin stimulation. This method is extensively used to elicit muscle contraction, promote healing and decrease edema.
Vector effect
The meddling field is interchanged to an angle of 450 in each way, the field thus covers a wider area. This is valuable in diffuse pathology or if the site of the cut cannot be precisely localized.
Incidence swings
Some paraphernalia permits a disparity in the speed of the incidence swing. A recurring mode may be an unceasing swing from 0 to 100 Hz in 5-10s and back in a similar time or it may hold for 1-6s at one incidence followed by 1-6s at another incidence with a variable time to swing between the two.
Constant incidence
Some treatments may be approved with the interference fixed at a certain incidence. Recurring incidence is valuable if several kinds of tissues are to be treated at once. A difference in the incidence also overwhelms the problem of tissue accommodation where the response of a particular tissue cuts with time.
Incidence sweep
The principle of using the sweep is that the apparatus is set to mechanically vary the stimulation incidence, it uses either pre-set or user-set sweep ranges. The sweep range should be suitable to the wanted physiological effects.
The pattern of the sweep makes an important alteration in the stimulation received by the patient. Most apparatuses offer numerous sweep patterns:
Three-sided sweep patterns.
Four-sided Sweep Patterns.
Trapezoidal Sweep Patterns.
In the ‘triangular' sweep pattern, the machine progressively changes from the base to the top incidence, for 6 seconds. Although some machines bought from IFT machine Suppliers in India bid 1 or 3-second choices. All incidences between the base and top frequencies are transported in equal proportion.
Rectangular sweep is a dissimilar stimulation pattern in which the base and top incidences are set, but the machine then ‘switches' between these two precise frequencies rather than slowly changing from one to the other
One will transport a full array of stimulation frequencies between the set frequency levels and the other will switch from one occurrence to the other. The ‘trapezoidal' sweep is effectually a mixture of these two.
Interferential current treatment works by sending small amounts of an electrical stimulus to injured tissues in the body. The treatment is meant to increase the body's natural process of retorting to pain, by snowballing motion thus producing hormones that promote healing. IFT transports sporadic pulses to stimulate surface nerves and block the pain signal, by transporting incessant deep stimulation into the affected tissue. IFT dismisses pain, surges flow, cuts edema, and rouses the muscles. A frequency of 100Hz may rouse the large diameter A-beta fibers, which affect the discomfort gate and constrain the broadcast of small-diameter nociceptive traffic ( C and A-delta fiber), which efficiently closes the gait to sore impulses. Interferential current Surges the flow of blood thus dipping swelling, by washing away the chemicals that rouse the nociceptive nerve endings.
