Towards a more accurate quasi-static approximation of the electric potential for neurostimulation with kilohertz-frequency sources*

Objective. Our goal was to determine the conditions for which a more precise calculation of the electric potential than the quasi-static approximation may be needed in models of electrical neurostimulation, particularly for signals with …

Nerve excitation using an amplitude-modulated signal with kilohertz-frequency carrier and non-zero offset

BACKGROUND Incorporating kilohertz-frequency signals in transcutaneous electrical stimulation has been proposed as a means to overcome the impedance of the skin, thereby reaching deeper nerves. In particular, a transdermal amplitude modulated signal …

Volume conductor model of transcutaneous electrical stimulation with kilohertz signals.

OBJECTIVE: Incorporating high-frequency components in transcutaneous electrical stimulation (TES) waveforms may make it possible to stimulate deeper nerve fibers since the impedance of tissue declines with increasing frequency. However, the …

Circuit and volume conductor models of transcutaneous electrical stimulation

Electrical stimulation of peripheral nerves is a widespread technique for the treatment of neurological diseases and disorders. However, peripheral stimulation typically requires surgical implantation of an electrode and a pulse generator. …
