Sacral neuromodulation (SNM) is theorized to alter the neural pathways that mediate bladder and urethral sensation. We hypothesize that SNM affects current perception thresholds (CPTs) of afferent sensory nerve pathways. ⋯ With a measurable change in CPT values for Aδ-fibers and Aβ-fibers, these findings suggest that SNM modulates large myelinated afferent fibers in the bladder. Notably, little or no changes were found in the C-fiber CPT measurements. More research is needed with a larger sample size to determine the significance of these findings.

Intrathecal baclofen (ITB) pump implantation for cerebral palsy (CP) patients is usually performed in the lateral position; however, it might be difficult for some patients with severe deformity to take a lateral position during surgery. ⋯ Our findings suggest that ITB therapy may be useful for CP patients with uncontrollable spasticity, dystonia, or opisthotonus who are not able to take a lateral position for pump implantation due to deformities of their extremities and spine.

The aim of this review is to make specialists in a variety of disciplines familiar with basic aspects of spinal cord stimulation and the role of mathematical modeling in understanding its mechanisms of action and the solution of basic problems. ⋯ In particular the conclusions from several computer simulation studies are relevant and of interest to specialists in many disciplines.
