Amplipulse therapy (SMT therapy) is a method of local exposure to alternating sinusoidal modulated electric current of appropriate parameters through electrodes and wet hydrophilic pads, contacted to certain areas of the patient's skin.
Amplipulse therapy has a current strength of up to 50 mA; the main (carrier) frequency of current oscillations is 2-5 kHz, the modulation frequency is from 10 to 150 Hz.
Types of current modulation:
- constant modulation (I type of operation) - modulation of the carrier frequency of 5 kHz by one of the frequencies in the range of 10-150 Hz;
- burst - pause (II type of operation) - alternation of a burst of sinusoidal current, modulated by a frequency within 10-150 Hz, and pauses; the duration of the current bursts and pauses can be adjusted discretely within the range from 1 to 5-6 s;
- package - carrier frequency (III type of operation) - alternation of a current package modulated by a certain frequency within 10-150 Hz, with packages of unmodulated current of a carrier frequency of 5 kHz;
- alternating frequencies (IV type of operation) - alternation of current pulses with different modulation frequencies: in one of the pulses the modulation frequency is selected from the range of 10-150 Hz, in the second the modulation frequency remains constant - 150 Hz.
Amplipulse therapy can change the modulation depth from 0 to 100% and more. At a modulation depth of 100%, the amplitude between the oscillation series reaches zero; at a modulation depth exceeding 100%, the intervals between the oscillation series with zero amplitude are expanded.
The effect of the factor is in many ways similar to the method of diadynamic therapy. However, alternating electric current, unlike direct or single-half-period pulse current, causes adaptation of the central nervous system to the effect to a much lesser extent, which contributes to more stable electrodynamic changes in the corresponding structures and systems.
The main clinical effects of amplipulse therapy are: neuromyostimulating, analgesic, vasodilatory, and trophic.
