Multicenter Study Observational Study
An Algorithmic Programming Approach for Back Pain Symptoms in Failed Back Surgery Syndrome Using Spinal Cord Stimulation with a Multicolumn Surgically Implanted Epidural Lead: A Multicenter International Prospective Study.
Many studies have demonstrated the efficacy and the medical/economic value of epidural spinal cord stimulation for the treatment of "failed back surgery syndrome" (FBSS). However, the back pain component of FBSS has been recalcitrant. Recent clinical trials have suggested that multicolumn surgically implanted leads combined with enhanced programming capabilities in the newer implantable pulse generators demonstrate the ability to treat the back pain component of FBSS. The objective of our present international multicentre study is to prospectively evaluate these findings in a larger population. ⋯ This study confirms the hypothesis that multicolumn SCS should be considered as an important tool in the treatment of radicular and axial pain in FBSS patients. The efficacy of this modality is based on a rigorous patient selection process, access to new generation lead technologies, but most importantly an algorithmic programming approach for optimal stimulation and electrical field shaping. With over 40 million potential programming combinations associated with 16 contact leads to achieve paresthesia coverage, optimal stimulation is often missed as either the patient or the clinician become exhausted or overwhelmed during the course of therapy programming and optimization session.

Randomized Controlled Trial Comparative Study
Documenting female spine motion during coitus with a commentary on the implications for the low back pain patient.
To describe female lumbar spine motion and posture characteristics during coitus and compare these characteristics across five common coital positions. Exacerbation of low back pain during coital movements and positions is a prevalent issue reported by female low back pain (LBP) patients. To address this problem, the first study to examine lumbar spine biomechanics during coitus was conducted. ⋯ The findings provided here may guide the clinician's specific recommendations, including alternative coital positions and/or movement patterns or suggesting a lumbar support, depending on the female LBP patient's specific motion and posture intolerances.

The expanding role of physiotherapists, with increasing use of services such as self-referral, means that demonstrating an ability to understanding and ask red-flag questions appropriately has never been more important. The present study investigated how physiotherapists define common red flags, how they ask red-flag questions, which red flags they routinely record and the importance that therapists attribute to individual red-flags. ⋯ If only certain red flags are being assessed, this may put patients at risk of having serious spinal pathologies going undetected. Thus, strategies encouraging therapists to ask all red-flag questions may be needed. The importance of the more recently recognized red flags may need to be emphasized to clinicians. Finally, the inconsistent way in which the red-flag questions were asked highlights a potential practical barrier to translating red-flag knowledge into clinical practice. There is a need to build on this work, using in-depth qualitative interviews, to gain a deeper understanding of how therapists understand and apply the red flags commonly used in back pain assessment.

The relevance of a phobia-based conceptualization of fear for individuals with chronic pain has been much debated in the literature. This study investigated whether patients with highly fearful chronic low back pain show distinct physiological reaction patterns compared with less fearful patients when anticipating aversive back pain-related movements. We used an idiosyncratic fear induction paradigm and collected 2 different measures of autonomic nervous system activation and muscle tension in the lower back. ⋯ According to Bradley and Lang defense cascade model, this response is typical of a fear reaction. Participants showing the psychophysiological pattern typical of fear also had elevated scores on some self-report measures of components of the fear-avoidance model, relative to participants showing the reaction pattern characteristic of attention. This study is the first to provide psychophysiological evidence for the fear-avoidance model of chronic pain.

Back and joint pain are the most common extraintestinal symptoms reported by patients with inflammatory bowel disease (IBD). We assessed the impact of back/joint pain, illness perceptions, and coping on quality of life (QOL) and work productivity in patients with IBD. ⋯ Back/joint pain, illness perceptions, and coping are significant predictors of QOL and work productivity, after controlling for disease activity.
