Spinal cord stimulation (SCS) is expected to have analgesic effects in patients with neuropathic pain, ischemic pain, or mixed pain. The type of leg pain caused by lumbar spinal stenosis (LSS) is considered as mixed pain, which is expected to respond to SCS. However, there is no established view on the usefulness of SCS in the management of this type of pain. Therefore, we aimed at evaluating the efficacy of SCS against leg pain associated with LSS. ⋯ SCS seemed to be effective against leg pain associated with LSS. Thus, SCS should be actively adopted in indicated patients as a method of treatment intermediate between conservative therapy and surgical therapy.

The objective of this investigation was to evaluate magnetic resonance imaging (MRI) issues (magnetic field interactions, MRI-related heating, and artifacts) for a wirelessly powered lead used for spinal cord stimulation (SCS). ⋯ These findings demonstrated that it is acceptable for a patient with this wirelessly powered lead used for SCS to undergo MRI under the conditions utilized in this investigation and according to other necessary guidelines. Artifacts seen on magnetic resonance images may pose possible problems if the area of interest is in the same area or close to this lead.

Spinal cord stimulation (SCS) has become an evidence-based treatment for a variety of chronic pain disorders. A key step in appropriate patient selection and long-term outcome predictability is a percutaneous screening trial of stimulation. Occasionally, a trial cannot be adequately completed with a percutaneous electrode. Rather than depriving this therapy from these patients, the authors have developed a program providing surgically implanted paddle-lead screening trials of SCS. ⋯ Surgically implanted paddle-lead screening trials of SCS can be used safely and effectively in those patients in which an adequate percutaneous-electrode trial cannot be completed. Results are similar to those seen with standard percutaneous screening trials. A systematic approach to surgical-paddle screening trials of SCS has not been previously reported.

The aims were to investigate the energy-dose response effect of intestinal electrical stimulation (IES) on small bowel motility, to compare the effect of forward and backward IES, and to explore the possibility of using intermittent IES and mechanism of IES on intestinal motility. ⋯ IES with long pulses inhibits small intestinal motility; the effect is energy-dose dependent, diffused, and sustained. Intermittent IES has the same efficacy as the continuous IES in inhibiting small intestinal motility. Forward and backward IES have similar inhibitory effects on small bowel motility. This IES-induced inhibitory effect is mediated via the sympathetic pathway.
