FIELD: medicine; medical engineering. ^ SUBSTANCE: method involves producing pulses of given frequency, modulating the pulse durations, amplifying the pulses and sending them via electrodes to biological object skin surface. Subelectrode skin area impedance capacitive component rate is determined during stimulation. Impedance rate value being close to zero, stimulation time interval is to be hold within 3-5 min and the stimulation is stopped next to it. Device has oscillator connected to pulse duration modulator, stimulus power setter connected to the second modulator input, pulse power amplifier connected to pulse duration modulator output, indication unit connected to the first output of power amplifier and electrodes connected to the second pulse power amplifier output and differentiation unit input. The device also has pulse duration shaper, memory unit, timer and adder. Differentiation unit output is connected to pulse duration shaper input. Shaper output is connected to memory unit input with one of adder inputs. Memory unit output is connected to the other adder input. The adder output is connected to timer. Timer output is connected to indication unit. ^ EFFECT: enhanced effectiveness and objectiveness in determining procedure duration and dose. ^ 2 cl |
