Background and aims The co-morbidity between pain and depression is a target of interest for treatment. However most of the published literature on the topic has used clinical cohorts as the population of interest. The goal of this study was to use a nationally representative sample to explore how health outcomes varied across pain and depression status in a cohort sampled from the general US population. Methods This was a cross-sectional analysis of adults ≥18 years in the 2009-2010 National Health and Nutrition Examination Survey...

Background and aims Pain is the most common reason for delayed discharge after day-case laparoscopic cholecystectomy. This study investigates a simple five-item questionnaire in evaluating the risk of postoperative pain in day-case cholecystectomy and the efficacy and safety of single-dose preoperative pregabalin on patients with multiple risk factors for pain. There are no previous studies on targeting adjuvant pain treatment based on the individual risk factors like the preoperative state of anxiety, acute or chronic pain, and the expectation of pain in day-case surgery...

Background and aims Chronic pelvic pain (CPP) in women is a complex condition that can seriously impact health and quality of life. Clinical guidelines for CPP place great demands on healthcare professionals, as they require both specialized knowledge about the pelvic area and knowledge of the mechanisms of chronic pain. To ensure best possible assessment and treatment of these women it is important to bring about more knowledge of the special CPP features. The purpose of this paper is to describe the characteristics of women with CPP evaluated at the University Hospital of North Norway, and further referred to physiotherapy...

Background and aims Endogenous pain modulation can be studied in humans by conditioned pain modulation (CPM): pain induced by a test stimulus is attenuated by a distantly applied noxious conditioning stimulus. The detection of impaired CPM in individual patients is of potential importance to understand the pathophysiology and predict outcomes. However, it requires the availability of reference values. Methods We determined reference values of CPM in 146 pain-free subjects. Pressure and electrical stimulation were the test stimuli...

Background and aims The effect of stretching on joint range of motion is well documented and is primarily related to changes in the tolerance to stretch, but the mechanisms underlying this change are still largely unknown. The aim of this study was to investigate the influence of a remote, painful stimulus on stretch tolerance. Methods Thirty-four healthy male subjects were recruited and randomly assigned to an experimental pain group (n=17) or a control group (n=17). Passive knee extension range of motion, the activity of hamstring muscles and passive resistive torque were measured with subjects in a seated position...

Background and aims Chronic pain is a leading cause to years lived with disability worldwide. However, few of the interventions used in pain medicine have proven efficacy, and evidence from the existing studies may not be valid for the general pain population. Therefore, it is of utmost need that we describe chronic pain conditions in their most relevant aspects, their various guises, as well as the real world outcomes of our clinical interventions. The most obvious and crude way to make these assessments are through large registries where patient characteristics, treatment characteristics (including but not limited to what, when, how often and by whom), treatment outcomes and patient outcomes are scrutinized and recorded...

Background and aims While the Nordic countries have considerably stricter controls on opioid prescribing for chronic non-cancer pain than other countries, previous research has warned that prescription of strong opioids is increasing. This study examines consumption of and developments in dispensed prescribed opioids to individuals receiving ambulatory care from 2006 to 2017, using publicly available data from each of three Nordic countries' national prescription registries. Methods Repeated, cross-sectional design...

Background and aims Pain is a prevalent problem in many countries. Women are more often on sick-leave for pain than men. Such gender differences have been explained through biological factors, different demands for on the job market, and home conditions. Fewer studies have focused on how gender stereotypes may bias the medical assessment of pain patients. The aim of the present research was to investigate if a gender bias in medical students' evaluations of chronic pain patients can contribute to explaining the gender differences in sick-leave due to pain...

Background and aims Prior research indicates that swearing increases pain tolerance and decreases pain perception in a cold pressor task. In two experiments, we extend this research by testing whether taboo hand gesticulations have a similar effect. Methods Study 1 focused on males and females who, across two trials, submerged an extended middle finger (taboo) and an extended index finger (control) in ice water until discomfort necessitated removal. Study 2 focused exclusively on pain perception in males who, across three trials, submerged their hand, flat, with extended middle finger and with extended index finger, for 45 s each...

Background and aims This study has two main aims: (1) To explore the overlap between classification criteria in patients with Chronic Widespread Pain (CWP) and (2) To explore the use of the Patient Generated Index (PGI) as a quality of life (QoL) measure in this patient group. Methods Patients with Widespread Pain (ICD-11: pain in four or more out of five bodily regions, i.e. the four quadrants and axially) in a tertiary pain outpatient clinic were assessed according to classification criteria for Fibromyalgia [FM, American College of Rheumatology (ACR) criteria of 1990, 2010, 2011 and 2016], Chronic Fatigue Syndrome [CFS, Fukuda, Canada and International Consensus Criteria (ICC)] and Bodily Distress Syndrome (BDS)...

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 A targeted pain program may prevent the progression and subsequent occurrence of chronic pain in adolescents. This study tested the effectiveness of a new acceptance and commitment therapy -based pain management intervention, using physical and psychological functions as the outcomes. The objective was also to determine whether Pediatric Pain Screening Tool risk profiles function as outcome moderator in the current sample. A valid screening tool would enable the program development. Methods Thirty-two consecutive adolescent patients (13-17 years old) with idiopathic recurrent musculoskeletal pain completed the study...

Background and aims The Fear-Avoidance Beliefs Questionnaire (FABQ) is the most widely used self-reported measure of fear-avoidance beliefs about work and physical activity in low back pain (LBP). However, there is no Hausa version for use in patients with LBP. This study aimed to translate, cross-culturally adapt, and test the psychometric properties of the Hausa version of the FABQ in patients with LBP. Methods The Hausa form of FABQ was developed using a forward-backward translation procedure according to recommended guidelines...

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...
