This study characterizes and validates a recently developed dedicated circular rat coil for small animal repetitive Transcranial Magnetic Stimulation (rTMS). ⋯ The coil is suitable for rTMS in rats and achieves unprecedented high E-fields at high stimulation frequencies and long durations with however a rather unfocal rat brain stimulation. Reproducible MEPs as well as alterations in cerebral glucose metabolism following rTMS were demonstrated.

Spinal Cord Stimulator (SCS) is a surgically implanted device for patients with certain types of chronic pain. While some studies show the value of psychological screening of potential SCS candidates, no consensus exists. This single-site study analyzed the association of SCS success with psychological assessments (e.g., Millon Behavioral Medicine Diagnostic), beliefs regarding SCS efficacy, self-reported pain and quality of life (QOL) among patients approved for SCS. ⋯ Predictors of pain relief and QOL following SCS may depend on expectations of the device and on individuals' interpretation of pain or psychosocial health.

To report a case with two years follow-up of neuropathic pain and functional limitations associated with multiple sclerosis (MS) effectively treated with an MRI conditional spinal cord stimulator (SCS) system that allowed for spinal imaging. To present a comprehensive literature review of spinal cord stimulator utilization in the treatment of multiple sclerosis. ⋯ We report the successful treatment of MS-associated pain and functional limitations with an MRI conditional spinal cord stimulator system. The ability to obtain post-implant MRI imaging of not only the brain but also the spinal cord in MS patients allows for the continued need to document and follow disease progression, especially with the advancements in pharmacological therapy.

Pre-operative psychological assessment is commonly used to assess patients for spinal cord stimulation (SCS). Though often times mandated by insurance, its value is frequently questioned. ⋯ The predictive value of psychological testing depends on which psychiatric factors are used and which outcomes are measured. The predictive capacity of psychological indications can be used to holistically treat patients, specifically to recommend psychiatric medication and consulting to supplement SCS treatment as needed.
