Özet:

Spinal cord stimulation is a pain management technique that uses pulsed electrical

energy near the spinal cord. Previously, pulsed energy was applied in the intrathecal

space, but now leads with electrodes are implanted in the epidural space. This study

investigates the effects of different electrode configurations on electrical parameters

such as cathode, anode, current density, electrical potential, and distance between

electrodes in contact with the spinal cord. This study used a detailed anatomical

spinal canal model with Epidural Fat, Cerebrospinal Fluid (CSF), and Gray and White

matter to examine the distributions of electric potential and current density in the

spinal canal. The charge per phase and charge density values at different frequencies

were also studied using eight-shaped electrode combinations and quadruple and

nine-electrode configurations. The results showed that electrode configurations can

generate significant differences in spinal cord stimulation.
