Review Meta Analysis
A systematic review and meta-analysis of yoga for low back pain.
To systematically review and meta-analyze the effectiveness of yoga for low back pain. ⋯ This systematic review found strong evidence for short-term effectiveness and moderate evidence for long-term effectiveness of yoga for chronic low back pain in the most important patient-centered outcomes. Yoga can be recommended as an additional therapy to chronic low back pain patients.

To test whether the prognostic definition of chronic pain, which has previously been applied in specific anatomic areas, performed well in a cohort of older adults with a range of musculoskeletal pain sites. ⋯ The prognostic approach to defining chronic pain is suitable for use in older adults consulting primary care with musculoskeletal pain at a range of sites, but new cutoffs are needed to allow for the higher risk profile in this group. An adapted version of this method may also have the potential for application directly within the clinical consultation.

This study examined the effects of exercise-induced muscle damage (EIMD) on the physiological and perceptual responses to 30 minutes of submaximal cycling at 60% of oxygen consumption (VO2 peak). ⋯ These findings indicate the elevations in RPE after EIMD are likely a consequence of the EIMD with the most likely explanation being an increase in localized pain before and during cycling exercise.

Multicenter Study Controlled Clinical Trial
Establishing an optimal "cutoff" threshold for diagnostic lumbar facet blocks: a prospective correlational study.
Diagnostic medial branch blocks (MBB) are considered the reference standard for diagnosing facetogenic pain and selecting patients for radiofrequency (RF) denervation. Great controversy exists regarding the ideal cutoff for designating a block as positive. The purpose of this study is to determine the optimal pain relief threshold for selecting patients for RF denervation after diagnostic MBB. ⋯ Employing more stringent selection criteria for lumbar facet RF is likely to result in withholding a beneficial procedure from a substantial number of patients, without improving success rates.

Activity pacing (AP) is a concept that is central to many chronic pain theories and treatments, yet there remains confusion regarding its definition and effects. ⋯ Future research on AP should be based on a clear theoretical foundation, consider the context in which the AP behavior occurs and the type of pacing problem ("underactivity" vs. "overactivity"), and should examine the impact of AP treatment on multiple clinical outcomes. We provide a provisional definition of AP and specific recommendations that we believe will move the field forward.
