Objective. Spinal cord stimulator (SCS) parameter settings have been well studied; however, the goal of this exploratory study was to examine the SCS parameters used during intra-operative stimulation (IOS) at trial lead placement. Methods. In this retrospective study, we report the IOS parameter settings for 22 patients who underwent thoracic SCS lead trial for treatment of refractory low back and/or leg pain. Results. Paresthesia coverage was shown to differ depending upon the pain syndrome and the region involved (back and/or leg, p = 0.03). ⋯ Important variations in field configuration practice patterns also emerged. Conclusions. Larger prospective studies are required to confirm and extend the current results. The ultimate goal for this report is to establish a foundation for future studies to create an evidence-based standardized algorithm for IOS to enhance the success rate of SCS trial screening.

Background. Spinal cord stimulation (SCS) is effective in reducing pain from a number of differing medical conditions that are refractory to other, more conservative treatments. Much is written in the literature regarding efficacy and safety of SCS; however, no one to our knowledge has compared and reported safety and efficacy of SCS when using differing manufactured SCS devices. We undertook such a preliminary evaluation. ⋯ Conclusions. Spinal cord stimulation improves pain, sleep, and function in patients with intractable pain. Because of the low number of patients evaluable in this study, we believe that conclusions should not be made regarding the effect of technology on outcomes or safety. We believe that an analysis of this type in larger populations is warranted to understand the role, if any, that present-day technology has on outcomes of SCS.

Background. Lyme disease is caused by Borrelia, a bacterium transmitted by the bite of a deer tick. A slow developing encephalopathy or an axonal polyneuropathy with distal paresthesia and spinal or radicular pain rarely occurs and can be hard to treat. ⋯ Results. After 18 months of therapy and follow-up, this patient's analgesia, as a result of SCS, continues to be excellent, with almost complete subjective pain relief and cessation of adjuvant analgesic medication. Conclusions. SCS may be efficacious for the treatment of neuropathic pain due to Lyme disease.

Controlled Clinical TrialOne-year outcome evaluation after interspinous implantation for degenerative spinal stenosis with segmental instability.
The authors hypothesized that the placement of the interspinous implant would show a similar clinical outcome to the posterior lumbar interbody fusion (PLIF) in patients having spinal stenosis with mild segmental instability and that this method would be superior to PLIF without significantly affecting degeneration at the adjacent segments. Forty two adult patients having degenerative spinal stenosis with mild segmental instability who underwent implantation of Coflex (Spine motion, Germany) or PLIF at L4-5 between January 2000 and December 2003 were consecutively selected and studied for one-year clinical outcome. ⋯ However, the range of motion at the upper adjacent segments (L3-4) increased significantly after surgery in the PLIF group, which was not manifested in the Coflex group during the follow-up. The authors assumed that interspinous implantation can be an alternative treatment for the spinal stenosis with segmental instability in selected conditions posing less stress on the superior adjacent level than PLIF.

To identify risk factors for new episodes of sick leave due to neck or back pain. ⋯ The most consistent risk factors for new episodes of sick leave due to neck or back pain found during both the follow-ups were blue-collar work and several earlier episodes of neck or back pain assessed at baseline. Preventive efforts to decrease sick leave due to neck or back pain may include measures to increase the occurrence of positive challenges at work and to minimise repetitive work procedures. An evidence-based secondary prevention of neck and back pain including advice to stay active is also warranted.
