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.

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.

In previous research a close link between depression and postoperative pain has been described. However, the direction of impact remains unclear. The present longitudinal study aimed to clarify the prognostic value of depressive symptoms for perioperative pain and to explore the causal nature of the association between depressive symptoms and perioperative pain. ⋯ Our results suggest that early postoperative depressive symptoms predicts pain at discharge and preoperative pain predicts postoperative depressive symptoms. In conclusion, perioperative pain therapy should include the treatment of both, pain and depressive symptoms, to achieve sufficient pain relief. The evidence regarding the causal relationships between depressive symptoms and perioperative pain, however, must be tested in future research.

Comparative Study
Compliance and persistence of antidepressants versus anticonvulsants in patients with neuropathic pain during the first year of therapy.
Neuropathic pain (NP) is a chronic condition that has human, social, and economic consequences. A variety of agents can be used for treatment; however, antidepressants and anticonvulsants are the 2 classes most widely studied and represent first-line agents in the management of NP. Little information is known about the adherence patterns of these medications during the first year of therapy in patients with NP. ⋯ Compliance and persistence rates were similar for patients with NP diagnosis taking antidepressants and anticonvulsants. Higher compliance was observed among patients taking venlafaxine; however, this population did have a small sample size.
