چکیده مقاله
A transcutaneous amplitude modulated signal TAMS , in which a high frequency 210 kHz sinusoidal carrier is modulated by a traditional rectangular pulse, was proposed as a non invasive neurostimulation approach that can modulate bladder activity similarly to direct pudendal nerve stimulation The use of high frequency waveforms for TES is suggested by the reduced impedance of the skin with increasing frequency Thus, it may be possible to reach deeper structures by adding high frequency components to the stimulation waveform We implemented a multilayer volume conductor model including dispersion and capacitive effects, coupled to a cable model of a nerve fiber We simulated voltage and current controlled transcutaneous stimulation, and quantified the effects of frequency on the distribution of potentials and fiber excitation Our model suggests that high frequency signals generate larger potentials at depth than low frequencies However, incorporating kHz signals in the stimulation waveform does not necessarily facilitate fiber excitation
