Expectations can dramatically influence the perception of pain, as has been shown in placebo analgesia or nocebo hyperalgesia. Here, we investigated the role of expectation on the interruptive function of pain - the negative consequences of pain on cognitive task performance - in 42 healthy human subjects. ⋯ We show that the interruptive function of pain on concurrent visual task performance is influenced by expectation. Positive expectation can abolish the detrimental effects of pain on cognition. These expectancy effects on the interruptive function of pain are mediated by changes in functional connectivity between rostral ACC, posterior fusiform cortex and the hippocampus.

This study aimed to investigate the effects of fear of pain (FOP) and threat on attentional biases, using eye-tracking methods. ⋯ Interventions that change attention towards pain to reduce vigilance and subsequent avoidance may be indicated to improve pain outcomes.

Review Meta Analysis
Efficacy and tolerability of muscle relaxants for low back pain: Systematic review and meta-analysis.
Muscle relaxants are commonly prescribed for low back pain (LBP); however, there is limited evidence of their clinical efficacy and tolerability. This review evaluated the efficacy and tolerability of muscle relaxants in people with LBP. We searched online databases including Medline, EMBASE, CENTRAL and PsycINFO (inception to end October 2015) and performed citation tracking for eligible randomized controlled trials (RCTs). ⋯ Prolonged use of these medicines in LBP cannot be guided by trial evidence. WHAT DOES THIS REVIEW ADD?: Muscle relaxants provide clinically significant pain relief for acute low back pain. Caution must be taken with the interpretation of the findings as the evidence comes from specific muscle relaxant medicines.

Review Meta Analysis
Efficacy, acceptability and safety of guided imagery/hypnosis in fibromyalgia - A systematic review and meta-analysis of randomized controlled trials.
This systematic review aimed at evaluating the efficacy, acceptability and safety of guided imagery/hypnosis (GI/H) in fibromyalgia. Cochrane Library, MEDLINE, PsycINFO and SCOPUS were screened through February 2016. Randomized controlled trials (RCTs) comparing GI/H with controls were analysed. ⋯ There were no statistically significant differences between combined therapy and CBT alone in other primary outcomes at the end of treatment and follow-up. No study reported on safety. GI/H hold promise in a multicomponent management of fibromyalgia.

Review Practice Guideline
Clinical practice guidelines for the noninvasive management of low back pain: A systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.
We conducted a systematic review of guidelines on the management of low back pain (LBP) to assess their methodological quality and guide care. We synthesized guidelines on the management of LBP published from 2005 to 2014 following best evidence synthesis principles. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane, DARE, National Health Services Economic Evaluation Database, Health Technology Assessment Database, Index to Chiropractic Literature and grey literature. ⋯ Ten guidelines were of high methodological quality, but updating and some methodological improvements are needed. Overall, most guidelines target nonspecific LBP and recommend education, staying active/exercise, manual therapy, and paracetamol or NSAIDs as first-line treatments. The recommendation to use paracetamol for acute LBP is challenged by recent evidence and needs to be revisited.
