- The purpose of this study was to identify and describe subgroup profiles based on self-reported pain intensity, disability, self-efficacy, fear of movement/(re)injury, and catastrophizing in patients with musculoskeletal pain. Two primary health care samples (n = 215 and n = 161) were used. Self-report questionnaires were completed at the start of physical therapy treatment. Cluster analysis was used to generate subgroups. Three subgroups were identified in sample 1 and replicated in sample 2. These were labeled "High self-efficacy-Low fear-avoidance," "Low self-efficacy-Low fear-avoidance," and "Low self-efficacy-High fear-avoidance." The subgroups differed significantly in work-status in both samples (P < .001), but not in age, gender, or duration of pain. The results show the presence of subgroups based on pain intensity, disability, self-efficacy, fear of movement/(re)injury, and catastrophizing. The profile patterns suggest that different management strategies may be relevant in each subgroup. Perspective This article presents subgroups of patients with musculoskeletal pain with different profiles in pain intensity, disability, and psychosocial variables possible to modify by physical therapy management. The results could potentially aid clinicians in tailoring assessment and treatment approaches to each subgroup.

- Primary headaches such as migraine are postulated to involve the activation of sensory trigeminal pain neurons that innervate intracranial blood vessels and the dura mater. It is suggested that local activation of these sensory nerves may involve dural mast cells as one factor in local inflammation, causing sensitization of meningeal nociceptors. Immunofluorescence was used to study the detailed distribution of calcitonin gene-related peptide (CGRP) and its receptor components calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein 1 (RAMP1) in whole-mount rat dura mater and in human dural vessels. The relative distributions of CGRP, CLR, and RAMP1 were evaluated with respect to each other and in relationship to mast cells, myelin, substance P, neuronal nitric oxide synthase, pituitary adenylate cyclase-activating polypeptide, and vasoactive intestinal peptide. CGRP expression was found in thin unmyelinated fibers, whereas CLR and RAMP1 were expressed in thicker myelinated fibers coexpressed with an A-fiber marker. CLR and RAMP1 immunoreactivity colocalized with mast cell tryptase in rodent; however, expression of both receptor components was not observed in human mast cells. Immunoreactive substance P fibers coexpressed CGRP, although neuronal nitric oxide synthase and vasoactive intestinal peptide expression was very limited, and these fibers were distinct from the CGRP-positive fibers. Few pituitary adenylate cyclase-activating polypeptide immunoreactive fibers occurred and some colocalized with CGRP.

Proinflammatory Dietary Intake Relates to Pain Sensitivity in Chronic Nonspecific Low Back Pain: A Case-Control Study
- 2024

- Nonspecific chronic low back pain (nCLBP) has been associated with nutrition. Yet, it is not clear how nutritional factors and nCLBP relate to one another. Therefore, the aim of the present study was to investigate differences in diet quality and dietary intake levels between nCLBP patients and healthy controls (HCs) and explore the association between nutritional factors and pain sensitivity in nCLBP. In this case -control study, 106 participants (ie, n = 53 nCLBP and n = 53 HCs) were recruited and completed a 3 -day food diary to assess their dietary intake, which allowed to generate individual diet quality scores (ie, the Healthy Eating Index -2015 and Dietary Inflammatory Index). Additionally, each participant underwent an experimental pain assessment (quantitative sensory testing) and filled out selfreported pain questionnaires. Compared to HCs, the nCLBP group showed significantly lower diet quality, higher inflammatory scores, and a lower intake of total protein, total fat, dietary fiber, omega -3 fatty acids, vitamin B6, vitamin A, beta -carotene, vitamin E, and magnesium. Pain sensitivity mainly showed a negative correlation with nutritional intakes known for anti-inflammatory properties (ie, vitamins E, D, A, B6, B12, and zinc). Interestingly, total fat, cholesterol, saturated, and monounsaturated fat intakes were found to be inversely associated with pain sensitivity. Overall, patients with nCLBP have a lower diet quality, eat more proinflammatory, have less intake of nutrients known for their anti-inflammatory and antioxidative properties, and drink less water compared to HCs. Accordingly, pain sensitivity was mainly found to be positively associated with proinflammatory dietary intake. Perspective: This study emphasizes the association between a proinflammatory diet and nCLBP. Among nCLBP patients, positive association between increased pain sensitivity and the proinflammatory potential of a diet, highlighting the potential for individualized pain management strategies and leading to the development of novel therapeutic methods.

- That certain psychological factors are negatively associated with function in patients with chronic pain is well established. However, few studies have evaluated these factors in individuals with chronic pain from the general population. The aims of this study were to: 1) evaluate the unique associations between catastrophizing and perceived solicitous responses and psychological function, physical function, and insomnia severity in individuals with neuropathic pain, osteoarthritis, or spinal pain in the general population; and 2) determine if diagnosis moderates the associations found. Five hundred fifty-one individuals from the general population underwent examinations with a physician and physiotherapist, and a total of 334 individuals were diagnosed with either neuropathic pain (n = 34), osteoarthritis (n = 78), or spinal pain (n = 222). Results showed that catastrophizing was significantly associated with reduced psychological and physical function, explaining 24% and 2% of the variance respectively, whereas catastrophizing as well as perceived solicitous responding were significantly and uniquely associated with insomnia severity, explaining 8% of the variance. Perceived solicitous responding was significantly negatively associated with insomnia severity. Moderator analyses indicated that: 1) the association between catastrophizing and psychological function was greater among individuals with spinal pain and neuropathic pain than those with osteoarthritis, and 2) the association between catastrophizing and insomnia was greater among individuals with spinal pain and osteoarthritis than those with neuropathic pain. No statistically significant interactions including perceived solicitous responses were found. The findings support earlier findings of an association between catastrophizing and function among individuals with chronic pain in the general population, and suggest that diagnosis may serve a moderating role in some of these associations. Perspective: When examining persons with pain in the general population, catastrophizing is associated with several aspects of function, and diagnosis serves as a moderator for these associations. The replication of these associations in the general population support their reliability and generalizability.

Tidskriftsartikel (refereegranskat)abstract
- Chronic low back pain (CLBP) is a major cause of global disability and improving management is essential. Acceptance and commitment therapy (ACT) is a promising treatment for chronic pain but has not been modified for physical therapy. This randomized controlled trial (RCT) compared physical therapy informed by ACT (PACT) against standard care physical therapy for patients with CLBP. Patients with CLBP (duration ≥12 weeks, mean 3 years) were recruited from physical therapy clinics in 4 UK public hospitals. The Roland-Morris Disability Questionnaire (RMDQ) at 3 months' post-randomization was the primary outcome. Two hundred forty-eight participants (59% female, mean age = 48) were recruited and 219 (88.3%) completed measures at 3 and/or 12 months' follow-up. At 3 months, PACT participants reported better outcomes for disability (RMDQ mean difference = 1.07, p = .037, 95% CI = -2.08 to -.07, d = .2), Patient Specific Functioning (p = .008), SF12 physical health (p = .032), and treatment credibility (p < .001). At 12 months' follow-up, there were no significant differences between groups. PACT was acceptable to patients and clinicians and feasible to deliver. Physical therapists incorporated psychological principles successfully and treatment was delivered with high (≥80%) fidelity. Our results may inform the management of CLBP, with potential benefits for patients, health care providers, and society. PERSPECTIVE: Psychologically informed physical therapy has great potential but there are challenges in implementation. The training and support included in the PACT trial enabled the intervention to be delivered as planned. This successfully reduced disability in the short but not long term. Findings could inform physical therapists' treatment of CLBP.

Tidskriftsartikel (refereegranskat)abstract
- In both pain research and clinical practice, patient-reported outcome measures are used to assess dimensions of health. Interpreting these instruments requires understanding their measurement error and what magnitude of change has subjective importance for patients. This study estimated the standard error of measurement, 1-year minimal detectable change, and 1-year minimal clinically important difference (MCID) for the Short Form-36 Health Survey physical component summary and mental component summary, the Hospital Anxiety and Depression Scale subscales for anxiety symptoms and depression symptoms, and the numeric rating scale for past-week average pain intensity. MCIDs for these instruments have not previously been estimated in a large sample of chronic pain patients participating in interdisciplinary pain rehabilitation. Data were drawn from the Swedish Quality Registry for Pain Rehabilitation (n = 8,854 patients). MCID was estimated as average change and change difference based on 3 different anchors. MCID estimates were 2.62 to 4.69 for Short Form-36 Health Survey physical component summary, 4.46 to 6.79 for Short Form-36 Health Survey mental component summary, .895 to 1.48 for numeric rating scale, 1.17 to 2.13 for anxiety symptoms in the Hospital Anxiety and Depression Scale, and 1.48 to 2.54 for depression symptoms in the Hospital Anxiety and Depression Scale. The common assumption of an identical standard error of measurement for pre- and post-treatment measurements was not always applicable. When estimating MCID, researchers should select an estimation method and anchor aligned with the study's context and objectives. Perspective: This article presents estimates of MCID and minimal detectable change for several commonly used patient-reported outcome measures among patients with chronic pain. These estimates can help clinicians and researchers to determine when a measured health improvement is subjectively important to the patient and greater than measurement error.

The Association Between Immune-Related Conditions Across the Life-Course and Provoked Vulvodynia
- 2023
-
Ingår i: Journal of Pain. - : Elsevier BV. - 1526-5900 .- 1528-8447. ; 24:8, s. 1415-1422

Tidskriftsartikel (refereegranskat)abstract
- Vulvodynia, impacts up to 8% of women by age 40, and is hypothesized to manifest through an altered immune-inflammatory response. To test this hypothesis, we identified all women born in Sweden between 1973 and 1996 diagnosed with localized provoked vulvodynia (N76.3) and/or vaginismus (N94.2 or F52.5) between 2001 and 2018. We matched each case to two women from the same birth year with no vulvar pain ICD codes. As a proxy for immune dysfunction, we used Swedish Registry data to capture 1) immunodeficiencies, 2) single organ and multiorgan autoimmune conditions, 3) allergy and atopies, and 4) malignancies involving immune cells across the life course. Women with vulvodynia, vaginismus or both were more likely to experience immune deficiencies (OR 1.8, 95% CI, 1.2–2.8), single organ (OR 1.4, 95% CI, 1.2–1.6) and/or multi-organ (OR 1.6, 95% CI, 1.3–1.9) immune disorders, and allergy/atopy conditions (OR 1.7, 95% CI, 1.6–1.8) compared to controls. We observed greater risk with increasing numbers of unique immune related conditions (1 code: OR = 1.6, 95% CI, 1.5–1.7; 2 codes: OR = 2.4, 95% CI, 2.1–2.9; 3 or more codes: OR = 2.9, 1.6–5.4). These findings suggest that women with vulvodynia may have a more compromised immune system either at birth or at points across the life course than women with no vulvar pain history.

Cost-Effectiveness and Cost-Utility of Internet-Delivered Exposure Therapy for Fibromyalgia : Results From a Randomized, Controlled Trial
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Fibromyalgia (FM) is a prevalent and debilitating chronic pain disorder associated with a substantial economic burden. Although there are several studies investigating the effectiveness of psychological treatments such as cognitive-behavioral therapy for FM, studies on cost-effectiveness are scarce. The aim of the present study was to investigate the cost-effectiveness of Internet-delivered exposure therapy (iExp) for FM. We used health economic data from a recently conducted randomized, controlled trial, where 140 participants were randomized to either iExp or a waitlist control (WLC) condition. Economic data were collected at pre-treatment, post-treatment, and at the 1-year follow-up. Treatment effectiveness in relation to costs were analyzed using both a societal perspective (including all direct and indirect costs) and a health care unit perspective (including only the direct treatment costs). Bootstrapped net benefit regression analyses were also conducted, comparing the difference in costs and effects between iExp and WLC, within different willingness-to-pay scenarios. Results showed that the incremental cost-effectiveness ratio was -$15,295, indicating that iExp was highly cost-effective as each successfully treated case (treatment responder) was associated with a substantial net reduction in costs. The robustness of the results was tested in 2 different sensitivity analyses, where iExp remained cost-effective, even in a willingness-to-pay-scenario of $0. We conclude that iExp is a cost-effective treatment that generates large societal cost savings.PERSPECTIVE: Health-economic evaluations of psychological interventions for FM are scarce. This study is a cost-effectiveness analysis of Internet-delivered exposure therapy for patients with FM. Results showed that iExp was highly cost-effective compared with no treatment, where each successfully treated case generated a substantial societal cost saving.
