Human lumbar spinal cord networks controlling stepping and standing can be activated through posterior root stimulation using implanted electrodes. A new stimulation method utilizing surface electrodes has been shown to excite lumbar posterior root fibers similarly as with implants, an unexpected finding considering the distance to these target neurons. In the present study we apply computer modeling to compare the depolarization of posterior root fibers by both stimulation techniques. We…

A detailed three-dimensional volume conductor model of the torso and the McIntyre-Richard-Grill axon model are used to calculate the thresholds of axons within the posterior columns in response to transcutaneous lumbar spinal cord stimulation.

Epidural Stimulation of Rat Spinal Cord at Lumbosacral Segment Using a Surface Electrode: A Computer Simulation Study

It is concluded that the computational ESCS model is a valuable tool to obtain a better insight into the immediately evoked electrophysiological phenomena in animal models, and provides further guidelines for conducting animal experiments to enhance the exploration of basic neural mechanisms.

Common neural structures activated by epidural and transcutaneous lumbar spinal cord stimulation: Elicitation of posterior root-muscle reflexes

The present results strongly corroborate the activation of common neural input structures to the lumbar spinal cord—predominantly primary afferent fibers within multiple posterior roots—by both techniques and add to unraveling the basic mechanisms underlying electrical SCS.

Finite Element Models of Transcutaneous Spinal Cord Stimulation

Computer simulations are crucial for understanding the neuromodulative effects of transcutaneous SCS resulting from the transsynaptic activation of the spinal cord neural circuits and for further improving the stimulation technique.

Body Position Influences Which Neural Structures Are Recruited by Lumbar Transcutaneous Spinal Cord Stimulation

It is hypothesized that body position influences the preferential stimulation of sensory or motor fibers and changes of root-fiber paths within the generated electric field when in the prone position increase the stimulation thresholds of posterior above those of anterior root fibers.

Influence of Spine Curvature on the Efficacy of Transcutaneous Lumbar Spinal Cord Stimulation

Spinal flexion reduced the capacity of the stimulation to activate afferent fibers and led to the co-activation of motor fibers in the anterior roots, which recommended applying transcutaneous spinal cord stimulation in body positions that allow individuals to maintain a neutral or extended spine.

Recruitment of Upper-Limb Motoneurons with Epidural Electrical Stimulation of the Primate Cervical Spinal Cord

The results indicate that interfaces with lateral electrodes can target individual posterior roots and achieve selective modulation of arm motoneurons via the direct recruitment of pre-synaptic pathways and provide a framework for the design of neuro-technologies to improve arm and hand control in humans with quadriplegia.

Epidural electrical stimulation of posterior structures of the human lumbosacral cord: 2. quantitative analysis by computer modeling

Simulation of the computed recruitment order of an ensemble of ventral and dorsal root fibers shows a strong relation between electrode position and the order of muscle twitches which is based on the segmental arrangement of innervation of lower limb muscles.

Excitation of dorsal root fibers in spinal cord stimulation: a theoretical study

The results of this modeling study predict that, besides the well known influence of fiber diameter, the curvature of the dorsal root fiber and the angle between these fibers and the spinal cord axis are a major influence on their threshold values.

Epidural electric stimulation of posterior structures of the human lumbar spinal cord: 1. muscle twitches – a functional method to define the site of stimulation

The findings regarding amplitude, latency and recruitment order strongly suggest that the chances to stimulate upper lumbar cord segments are best around the 12th thoracic vertebra, and not posterior columns of the lumbr spinal cord.

Two-dimensional finite-element models representing non-homogeneous electrical conductivity of the human thorax in the mid-sagittal and tranverse planes suggest support is given to the view that stimulation from epidural electrodes place dorsolaterally will preferentially involve dorsal root axons.

Epidural spinal cord stimulation: calculation of field potentials with special reference to dorsal column nerve fibers

The effect of electrical stimulation with several electrode combinations on nerve fibers with different orientations in the spinal cord was investigated by computing the steady-state field potentials and activating functions and it was concluded that the cathodal stimulation, mediodorsally in the epidural space, longitudinal fibers are depolarized, but dorsoventral ones are hyperpolarized.

It is demonstrated that posterior root afferents can also be depolarized by transcutaneous stimulation with moderate stimulus intensities, and represents a novel, non‐invasive, neuromodulative approach for individuals with different neurological disorders.
