Chronic fibromyalgia (FM) pain is prevalent (estimated as high as 13%), predominantly affects women, and is associated with a variety of focal pain conditions. Ongoing FM pain is referred to deep tissues and is described as widespread but usually is maximally located within a restricted region such as the shoulders. Palpation of deep tissues reveals an enhanced nociceptive sensitivity that is not restricted to regions of clinical pain. ⋯ Thus, it appears that central mechanisms of FM pain are dependent on abnormal peripheral input(s) for development and maintenance of this condition. A substantial literature defines peripheral-CNS-peripheral interactions that are integral to FM pain. These reciprocal actions and related phenomena of relevance to FM pain are reviewed here, leading to suggestions for testing of therapeutic approaches.

Although the etiology of chronic pain following trauma is not well understood, numerous retrospective studies have shown that a significant proportion of chronic pain patients have a history of traumatic injury. The present analysis examines the prevalence and early predictors of chronic pain in a cohort of prospectively followed severe lower extremity trauma patients. Chronic pain was measured using the Graded Chronic Pain Scale, which measures both pain severity and pain interference with activities. ⋯ In addition, high reported pain intensity, high levels of sleep and rest dysfunction, and elevated levels of depression and anxiety at 3 months post-discharge were also strong predictors of chronic pain at seven years (p<0.001 for all three predictors). After adjusting for early pain intensity, patients treated with narcotic medication during the first 3 months post-discharge had lower levels of chronic pain at 84 months. It is possible that for patients within these high risk categories, early referral to pain management and/or psychologic intervention may reduce the likelihood or severity of chronic pain.

The objectives of this cross-sectional study conducted in primary care practice in France were to describe general practitioners' (GPs) fear-avoidance beliefs about low back pain (LBP), investigate the impact of these beliefs on their following guidelines for bed rest, physical activities, and sick leave, and uncover factors associated with GPs' fear-avoidance beliefs. A total of 864 GPs completed a 5-part self-administered questionnaire. Parts 1, 2, and 3 concerned demographic, professional data, and personal history of back pain, respectively. ⋯ FABQ Phys score was associated with recommendation of bed rest or rest during sick leave (p<0.0001) for acute LBP and less advice to maintain maximum bearable physical activities (p<0.001) for chronic LBP. FABQ Work score was associated with prescribing sick leave during painful periods (p<0.005) for acute LBP and less advice to maintain maximum bearable physical activities (p<0.001) for chronic LBP. GPs' fear-avoidance beliefs about LBP negatively influence their following guidelines concerning physical and occupational activities for patients with LBP.

Research on the role of acceptance in adjustment to persisting pain has been facilitated by the development of the Chronic Pain Acceptance Questionnaire (CPAQ). However, to date the CPAQ has been used to explore acceptance of pain without taking into account the likely contribution of other cognitive variables that have been shown to influence adjustment to persisting pain. This study examined the role of pain acceptance, as measured by the CPAQ, in accounting for adjustment to pain when controlling for the effects of other cognitive variables. ⋯ These findings differ from some reported previously and they suggest that the CPAQ, by itself, may not be sufficient to explain the processes of acceptance of pain and, hence, adjustment to pain. The findings also indicate that the Pain willingness subscale of the CPAQ is not robust and should be discarded. A broader approach to investigating acceptance of pain is proposed.
