Kilohertz

A partially averaged system to model neuron responses to interferential current stimulation

The interferential current (IFC) therapy is a noninvasive electrical neurostimulation technique intended to activate deep neurons using surface electrodes. In IFC, two independent kilohertz-frequency currents purportedly intersect where an …

Model Quantification of Axon Responses to Kilohertz SCS for the Treatment of Chronic Pain

Fondecyt 11190822: Model-based analysis of a novel modality of spinal cord stimulation for the treatment of chronic pain

Spinal cord stimulation (SCS) is a well-established therapy to relieve pain in subjects with chronic pain. In this therapy, electrical currents are delivered to the dorsal column (DC) of the spinal cord via electrodes implanted in the epidural space.

Quantification of dorsal column fiber responses in a model of kilohertz-frequency spinal cord stimulation

Introduction: Kilohertz-frequency spinal cord stimulation (KHF-SCS) was recently proposed as a paresthesia-free treatment for persons with chronic pain that is potentially more effective than conventional (~ 50 Hz) SCS. In SCS, the applied electrical …

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 …

Quantification of Dorsal Column Fiber Responses in a Model of Kilohertz-Frequency Spinal Cord Stimulation

Introduction Kilohertz-frequency spinal cord stimulation (KHF-SCS) was recently proposed as a paresthesia-free treatment for persons with chronic pain that is potentially more effective than conventional (̃50 Hz) SCS. In SCS, the applied electrical …

Quantitative Analysis of Kilohertz-Frequency Neurostimulation

Mainstream electrical stimulation therapies, e.g., spinal cord stimulation (SCS) and deep brain stimulation, use pulse trains that are delivered at rates no higher than 200 Hz. In recent years, stimulation of nerve fibers using kilohertz-frequency …

Effects of frequency-dependent membrane capacitance on neural excitability

Objective. Models of excitable cells consider the membrane specific capacitance as a ubiquitous and constant parameter. However, experimental measurements show that the membrane capacitance declines with increasing frequency, i.e., exhibits …

Phantom Model of Transcutaneous Electrical Stimulation with Kilohertz Signals

textcopyright 2015 IEEE. Transcutaneous electrical stimulation (TES) of nerve fibers may be optimized by overcoming the impedance of the skin using high-frequency (HF) stimulation signals. The excitation properties of nerve fibers depend on the …

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 …
