Stimulation of the dorsal root ganglion (DRG-S) has been shown to be an efficacious treatment option for refractory neuropathic pain syndromes. However, placement of the percutaneous leads for trial implantation can be challenging in patients with prior spinal surgical interventions resulting in anatomical changes and adhesions. ⋯ Transgrade lead placement for DRG-S may be an efficacious alternative to traditional anterograde DRG lead placement in cases where interlaminar access below the level of the DRG is not available, or desirable. Further studies are needed to clarify the safety and applicability of this approach.

An impairment of the peripheral nervous system has been suggested in fibromyalgia (FM). Noninvasive distal electrochemical skin conductance (ESC) has been studied little so far when combined with quantitative sensory testing (QST) in patients with FM. ⋯ This study shows that the sudomotor function is significantly impaired in patients with FM, especially on the dominant hand. This occurs in parallel with adjustments of detection and pain thresholds in the context of deficient spinal pain modulation. ESC values combined with QST values are relevant in the context of patients with FM and need to be explored further in this nociception-autonomic system intertwining.

Radiofrequency ablation (RFA) and spinal cord stimulation (SCS) are 2 common modalities used in management of various pain conditions. RFA generates heat and an electromagnetic field that can theoretically interfere with the functionality and longevity of the SCS device. This is problematic for patients who need RFA and have previously undergone implantation of an SCS device. ⋯ We also present device-specific industry guidelines and recommendations for performing RFA in patients following SCS device implantation.

Internet-based pain self-management for veterans: Feasibility and preliminary efficacy of the Pain EASE program.
To develop and test the feasibility and preliminary efficacy of a cognitive behavioral therapy-based, internet-delivered self-management program for chronic low back pain (cLBP) in veterans. ⋯ Veterans with cLBP may benefit from technology-delivered interventions, which may also reduce pain interference. Overall, veterans found that Pain EASE, an internet-based self-management program, is feasible and satisfactory for cLBP.
