Background and aims Following spinal cord injury (SCI), a majority of individuals may develop neuropathic pain, which further reduces quality of life. Pain is difficult to treat by medication; in fact, medication overuse may aggravate neuropathic pain in SCI by causing central sensitization (CS): a mechanism of hyper-reactivity of the dorsal horn neurons in the spinal cord with amplified cerebral pain response. The purpose of this study was to examine the presence of neuropathic pain and CS above the spinal lesion in SCI, and to investigate whether injury characteristics or medication influenced pain response...

Background and aims Posttraumatic stress disorder (PTSD) is related to more severe pain among chronic pain patients. PTSD is also related to dysfunctions or biases in several cognitive processes, including autobiographical memory. The autobiographical memories are our memories of specific personal events taking place over a limited amount of time on a specific occasion. We investigated how two biases in autobiographical memory, overgeneral memory style and negative emotional bias were related to pain, PTSD and trauma exposure in chronic pain patients...

Background and aims Achilles tendinopathy is common among runners, but the etiology remains unclear. High mechanical pain sensitivity may be a predictor of increased risk of developing Achilles tendinopathy in this group. The purpose of this study was to investigate whether local pain sensitivity could predict the development of Achilles tendinopathy in recreational male runners. The overall hypothesis was that high pain sensitivity would be related to a higher risk of developing Achilles tendinopathy among recreational male runners...

Background and aims Musculoskeletal pain may negatively affect work ability, especially when work demands are high and/or physical capacity of the worker is low. This study investigated the association between intensity of musculoskeletal pain in multiple body regions and work ability among young and old workers with sedentary and physical demanding jobs. Methods Currently employed wage earners (n=10,427) replied to questions about pain intensity, work ability, and physical work demands. The odds ratio (OR) for having a lower level of work ability in relation to the physical demands at work were modeled using logistic regression controlled for various confounders...

Background and aims Interpreting pain- and illness-related stimuli as health-threatening is common among chronic pain patients but also occurs in the general population. As interpretation bias (IB) may affect pain perception and might even play part in the development and maintenance of chronic pain, it is important to improve our understanding of this concept. Several studies suggest an association between IB and pain-related anxiety. However, those studies often rely on verbal and pictorial IB tasks that do not entail a threat of actual pain, therefore lacking personal relevance for healthy participants...

Background and aims Multidomain strategies (i.e. two or more strategies) for managing chronic pain are recommended to avoid excessive use of opioids while producing the best outcomes possible. The aims of this systematic review were to: 1) determine if patient-reported pain management is consistent with the use of multidomain strategies; and 2) identify the role of opioids and non-steroidal anti-inflammatory drugs (NSAIDs) in patient-reported pain management. Methods Bibliographic databases, websites, and reference lists of included studies were searched to identify published articles reporting community-based surveys of pain self-management from January 1989 to June 2017 using controlled vocabulary (and synonyms): pain; self-care; self-management; self-treatment; and adult...

Background and aims Among chronic pain patients who are referred to participation in a multimodal rehabilitation program (MMRP), pain catastrophizing and dysfunctional pain coping is common. In many cases it may have driven the patient to a range of unsuccessful searches for biomedical explanations and pain relief. Often these efforts have left patients feeling disappointed, hopeless and misunderstood. The MMRP process can be preceded by a multimodal investigation (MMI) where an important effort is to validate the patient to create a good alliance and begin a process of change towards acceptance of the pain...

Background and aims Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is challenging to live with, often accompanied by pervasive fatigue and pain, accompanied by decreased quality of life (QoL) as well as anxiety and/or depression. Associations between higher pain, lower QoL and higher anxiety and depression have been shown in patients with various chronic pain disorders. Few studies have however examined such associations in a sample of patients with ME/CFS. The aims of the current study were to examine the impact of pain levels and compare levels of pain, health related QoL, anxiety and depression between patients with ME/CFS and healthy controls...

Background and aims The interaction between the immune system and pain has been thoroughly explored in the recent decades. The release of inflammatory mediators from immune cells has the capability of activating neurons and glial cells, in turn sensitizing the nervous system. Both immune system alterations and pain modulation dysfunctions have been shown in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) following exercise. However, no studies tried to explore whether these two phenomena are linked and can explain exercise-induced symptoms worsening in people with ME/CFS...

Background and aims For some women, lumbopelvic pain (LPP) developed during pregnancy becomes a continuing post-partum problem. Increased understanding of potential prognostic factors is required. This study investigated whether active straight leg raise (ASLR), sleep dysfunction and pressure pain sensitivity during pregnancy are correlated with LPP intensity and quality, disability, and physical health-related quality of life (HRQoL) post-partum. Methods An exploratory, prospective cohort study design was used...

Background and aims As indicated by experimental studies, reports of pain intensity may depend on the examiner's gender. Until now, it is unclear whether this is relevant in clinical routine. This study investigated prospectively whether the gender of assessor plays a role in patients' pain reports and whether this role differs in male and female patients. Methods 165 patients (66.4 years±0.63; 118 males) scheduled for heart surgery were allocated consecutively to one examiner out of four students of both genders: two females and two males (aged 24...

Background and aims The choice of testing site for quantitative sensory testing (QST) of pain sensitivity is important and previous studies have demonstrated patterns in pain sensitivity within discrete areas in different body regions. Some areas are characterized by a relatively high degree of spatial pain discrimination and recognizable patterns of pain referral, whilst others are not. The lumbar region is likely to have relatively low pain acuity and overlapping of pain referral. The current study was conducted to determine whether patterns of pain sensitivity (detection thresholds) could be identified in the lower back, whether differences in such patterns exist between different groups and whether such patterns could help identify a clinical source of pain and localized increased pain sensitivity...

Background and aims Caring for children with chronic pain incurs burdens of cost and time for families. We aimed to describe variation in caregiver burden among parents of adolescents with chronic pain who responded to a nationally-representative survey. Our secondary aim was to identify child and parent characteristics associated with increased caregiver burden. Methods We used de-identified, publicly-available data from the 2016 National Survey of Children's Health (NSCH), designed to be representative of non-institutionalized children in the United States...
