Spinal Cord Stimulation for the Treatment of Neuropathic Pain Associated With Leprosy: A Case Report.
Leprosy is a major source of nerve damage and may lead to neuropathic pain as well as complex regional pain syndrome (CRPS). Spinal cord stimulation is an effective treatment for CRPS, but there are no reports of this treatment in a patient with leprosy. ⋯ Spinal cord stimulation may be a valuable intervention for patients with leprosy-induced CRPS.

The aim of this study was to investigate the strength of perceptual embodiment achieved during an adapted version of the rubber hand illusion (RHI) in response to a series of modified transcutaneous electrical nerve stimulation (TENS) pulse patterns with dynamic temporal and spatial characteristics which are more akin to the mechanical brush stroke in the original RHI. ⋯ The findings provide tentative, but not definitive, evidence that TENS parameters with dynamic spatial and temporal characteristics may produce more intense misattribution sensations and intense perceptual embodiment than parameters with static characteristics (e.g., continuous pulse patterns).

Neurostimulation of the hypoglossal nerve has shown promising results in the treatment of obstructive sleep apnea. This anatomic study describes the detailed topography of the hypoglossal nerve's motor points as a premise for super-selective neurostimulation in order to optimize results and minimize the risk of complications related to main nerve trunk manipulation. ⋯ A topographical map of the hypoglossal nerve terminal motor points was successfully created and could provide a framework for the optimization of the neurostimulation techniques.

Transcranial magnetic stimulation (TMS) is an effective intervention in noninvasive neuromodulation used to treat a number of neurophysiological disorders. Predicting the spatial extent to which neural tissue is affected by TMS remains a challenge. The goal of this study was to develop a computational model to predict specific locations of neural tissue that are activated during TMS. Using this approach, we assessed the effects of changing TMS coil orientation and waveform. ⋯ Our results indicate that the extent of neuromodulation is more widespread than previous published models suggest. Additionally, both specific locations in cortex and the extent of stimulation in cortex depend on coil orientation to within ±15° at a minimum. Lastly, through computational means, we are able to provide insight into the effects of TMS at a cellular level, which is currently unachievable by imaging modalities.

This testing was conducted to determine if exposure from a particle accelerator used to treat cancer patients would alter the performance of the EndoStim® neurostimulator when programmed either passively or actively and while being irradiated. ⋯ EndoStim I and EndoStim II implant pulse generators appear to be immune to x-ray radiation from the particle accelerator at energies up to 18 MV, at dose rates of up to 6 Gy/min, and up to cumulative doses of minimally 80 Gy. As there were no observable effects on neurostimulation requirements, the EndoStim LES Stimulation System implantable neurostimulators are capable of withstanding direct radiation. The recommendations of the manufacturer should be followed further regarding the labeling requirements for insured safety to patients.
