Pain

Overactivity (activity engagement that significantly exacerbates pain) is a common term in the chronic pain literature. Overactivity is accepted clinically as a behaviour that adversely affects an individual's daily functioning and is the target of one of the most widely endorsed pain management strategies among health professionals (ie, activity pacing). Little research, however, has investigated links between overactivity behaviour and indicators of patient functioning, and activity pacing has not been evaluated as a stand-alone treatment specifically for individuals with chronic pain who are habitually overactive. ⋯ Some participants who were followed up 3 to 6 months after a pain management program were able to learn pacing strategies and enact behaviour change with health professional support; however, the majority reported difficulties changing their behaviour after treatment. It is suggested that provision of pacing education, alone, to chronic pain patients who engage in overactivity behaviour may not be effective in eliciting behavioural change. Key factors that participants believed to contribute to the development and maintenance of their overactive behaviour in this study should be considered in future clinical approaches and empirical investigations.

Review Meta Analysis
THE PERIOPERATIVE USE OF PREGABALIN FOR ACUTE PAIN- A SYSTEMATIC REVIEW AND META- ANALYSIS.
Evidence supporting postoperative pain management using pregabalin as an adjunct intervention across various surgical pain models is lacking. The objective of this systematic review was to evaluate "model-specific" comparative effectiveness and harms of pregabalin following a previously published systematic review protocol. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from inception through August 2013. ⋯ Pregabalin analgesic effectiveness is largely restricted to surgical procedures associated with pronociceptive mechanisms. The clinical significance of observed pregabalin benefits must be weighed against the uncertainties about serious harms and enhanced recovery to inform the careful selection of surgical patients. Recommendations for future research are proposed.

Review
Research design considerations for chronic pain prevention clinical trials: IMMPACT recommendations.
Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. ⋯ Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.
