Recent studies suggest that sensory phenotyping may provide critical information for the diagnosis and management of patients with chronic neuropathic pain (NP). However, many formal quantitative sensory testing (QST) paradigms require expensive equipment, a dedicated location, and substantial time commitments on the part of patient and examiner, highlighting the need for a convenient and portable "bedside" QST battery. We developed and tested a bedside QST battery in a sample of patients with chronic NP.

Learn More >Objectives In evidence-based medicine, we base our conclusions on the effectiveness of interventions on the results of high-quality meta-analysis. If a new randomized controlled trial (RCT) is unlikely to change the pooled effect estimate, conducting the new trial is a waste of resources. We evaluated whether recommendations not to conduct further RCTs reduced the number of trials registered for two scenarios. Methods Analysis of registered trials on the World Health Organisation (WHO) International Clinical Trials Registry Platform (ICTRP). We regarded trial protocols relevant if they evaluated the effectiveness of (1) exercise for chronic low back pain (LBP) and (2) cognitive behavioural therapy (CBT) for chronic pain. We calculated absolute and relative numbers and change of registered trials in a pre-set time window before and after publication of the recommendations, both published in 2012. Results We found 1,574 trials registered in the WHO trial registry for exercise in LBP (459 before 2012; 1,115 after) and 5,037 trials on chronic pain (1,564 before 2012; 3,473 after). Before 2012, 13 trials on exercise for LBP (out of 459) fit the selection criteria, compared to 42 trials (out of 1,115) after, which represents a relative increase of 33%. Twelve trials (out of 1,564) regarding CBT for chronic pain, fit the selection criteria before 2012 and 18 trials (out of 3,473) after, representing a relative decrease of 32%. We found that visibility, media exposure and strength of the recommendation were related to a decrease in registered trials. Conclusions Recommendations not to conduct further RCTs might reduce the number of trials registered if these recommendations are strongly worded and combined with social media attention.
Learn More >Two factors related to the continuation of persistent pain are pain catastrophizing and illness perceptions. Pain neuroscience education is known to positively influence both in patients with persistent pain. As the integration of pain neuroscience education in monodisciplinary physiotherapy treatments is effective, integration in transdisciplinary cognitive-behavioral treatments seems recommendable. When doing so, the moderating effect of pain catastrophizing and perceptions on treatment results have to be examined, as these provide valuable information under which conditions treatment works. A bottom-up retrospective observational study evaluated the changes in clinical outcomes, and relationships between clinical outcomes and cognitive and emotional factors in patients with persistent pain. Multiple regression analysis, PROCESS macro, explored the moderating effects of pain catastrophizing on the relationship between illness perceptions and self-reported symptoms of central sensitization. In total, 78 patients were included in the study. A correlation between pretreatment scores and change scores in illness perceptions and self-reported symptoms of central sensitization following treatment were found (resp. R-sq 0.407, F(10,99) = 0.638, P = 0.000; R-sq 0.361, F(5, 54) = 0.609, P = 0.000; and R-sq 0.314, F(4,55) = 0.560, P = 0.00), however, moderation of pain catastrophizing scores on these correlations was not found. Even though an association between changes in pain catastrophizing and illness perceptions in patients with persistent pain was found, the direction or strength between the changes in illness perceptions and changes in self-reported symptoms of central sensitization was not influenced by pretreatment scores of pain catastrophizing.

Learn More >The US opioid crisis and increasing prescription rates in Europe suggest inappropriate risk perceptions and behaviours of people who prescribe, take or advise on opioids: physicians, patients and pharmacists. Findings from cognitive and decision science in areas other than drug safety suggest that people's risk perception and behaviour can differ depending on whether they learnt about a risk through personal experience or description. xperiencing the isk of overutilising pioids among patients with chronic on-cancer pain in mbulatory care (ERONA) is the first-ever conducted trial that aims at investigating the effects of these two modes of learning on individuals' risk perception and behaviour in the long-term administration of WHO-III opioids in chronic non-cancer pain.
Learn More >Fibromyalgia (FM) is a complex long-term condition associated with chronic widespread pain, fatigue, sleep problems, memory and concentration difficulties and irritable bowel syndrome. Current guidelines for the treatment of FM recommend nonpharmacological interventions. The Fibromyalgia Self-Management Programme (FSMP) is a nonpharmacological, multidisciplinary exercise and education group intervention. It aims to provide education and teach core skills, enabling those affected by FM to self-manage. The FSMP is currently codelivered by a multidisciplinary team within a secondary care service. The aim of this feasibility randomised controlled trial (RCT) is to determine the practicality and acceptability of delivering the FSMP in a community setting, informing a future RCT of effectiveness.
Learn More >We aimed to assess if subjects with diabetes exhibit higher prevalence of chronic back pain than age-sex-province of residence-matched non-diabetic controls. We also aimed to identify predictors for chronic neck pain (CNP) or chronic low back pain (CLBP) among subjects with diabetes. A case control study was conducted using data obtained from the Spanish National Health Survey 2017. Multivariable conditional and unconditional logistic regression models were constructed. A total of 2095 diabetes sufferers and 2095 non-diabetic matched controls were analyzed. The prevalence of CNP and CLBP was 27.3% and 34.8%, respectively, in diabetes sufferers and 22.1% and 29.0% in non-diabetes controls (both, < 0.001). After multivariable analysis, the ORs showed significantly higher adjusted risk of CNP (OR 1.34; 95% CI 1.19-1.51) and CLBP (OR 1.19, 95% CI 1.09-1.31) in diabetes cases. Diabetes sufferers with CNP or CLBP showed higher use of pain medication and higher prevalence of migraine/frequent headache than controls. Female sex, worse self-rated health and use of pain medication were predictors for CNP and CLBP in subjects with diabetes. CNP and CLBP are significantly more prevalent in diabetes sufferers than in controls. Current results can help to design better preventive and educational strategies for these highly prevalent and burdensome pains among diabetic patients.
