Identifying phenotypes in persons with temporomandibular disorders, using latent class analyses: Temporomandibular disorders and phenotypes.

Background: The heterogeneity of persons with temporomandibular disorders (TMD) and the lack of effective treatments have called for a biopsychosocial model and the development of a more personalised treatment approach. Emphasis on phenotypes might be a beneficial approach.

Objective: Identifying phenotypes among persons with TMD using potential prognostic factors, including personal characteristics and responses to clinical tests.

Musculoskeletal disorders in Norway: trends in health care utilization and patient pathways: a nationwide register study.

Objective: Describe trends in health care utilization, demographic characteristics and patient pathways among patients with musculoskeletal disorders (MSD) in Norway.

Design: Register-based cohort study.

Settings: Data were obtained from two Norwegian National registries; the Norwegian Control and Payment of Health Reimbursements Database (KUHR) and the Norwegian Patient Registry (NPR).

Pelvic girdle pain in pregnancy and early postpartum - prevalence and risk factors in a multi-ethnic cohort.

Background: Pelvic girdle pain (PGP) is common during and after pregnancy. It has been assumed that Scandinavian women report more PGP than women of other ethnicities. However, there are few population-based studies on ethnic differences and few with ethnicity as risk factor for PGP.

Clinical indicators for recommending continued care to patients with neck pain in chiropractic practice: a cohort study.

Background: Chiropractors' clinical indicators for recommending preventive continued care to patients with low back pain include previous pain episodes, a history of long pain duration and improvement after initial treatment. Our objectives were, in a cohort of patients with neck pain, to examine whether these clinical indicators were associated with being recommended continued care beyond 4 weeks, and if so whether this recommendation was dependent of chiropractor characteristics, as well as if the number of clinical indicators influenced this recommendation.

Methods: In this multi-center observational study, 172 patients seeking care for a new episode of neck pain in chiropractic practice in Norway were included between September 2015 and May 2016.

Cross-Cultural Contact and Norwegian Language Skills Among Ethnic Minority Women in Norway, and Relationship with Physical Activity in Pregnancy and Postpartum: The STORK-Groruddalen Cohort Study.

There are few studies of the migration context factors and physical activity (PA) level among minority ethnic women in Europe. We investigated the association between migration context factors and moderate to vigorous physical activity (MVPA) among minority ethnic women. Objectively recorded MVPA were obtained from 487 minority ethnic women included in the STORK-Groruddalen Cohort Study at three time points in pregnancy/postpartum.

Concomitant Unstable and Stable Gravity Stress Tests on Weight-Bearing Stable Weber B Ankle Fractures Treated Nonoperatively: A 2-Year Outcome Study.

Background: Replacing gravity stress tests with weight-bearing radiographs to evaluate the stability of Weber B (also called Lauge-Hansen supination-external rotation [SER]) ankle fractures results in a lower surgery rate, thus avoiding associated risks and complications. Still, nonoperative treatment of weight-bearing stable fractures is controversial because of the scarcity of strong evidence. We investigated the influence of a concomitant unstable gravity stress test compared with a stable gravity stress test on outcomes after nonoperative treatment of weight-bearing stable fractures.

Translation, reliability, and validity of the Norwegian version of the ABILHAND-NMD and the ACTIVLIM for Myotonic Dystrophy type 1.

Purpose: To translate ABILHAND-NMD and ACTIVLIM into Norwegian and assess their psychometric properties in adults with Myotonic Dystrophy type 1(DM1).

Methods: ABILHAND-NMD and ACTIVLIM were translated into Norwegian through a standardized translation process. Psychometric properties of the translated questionnaires were tested.

Associations between social support and physical activity in postpartum: a Norwegian multi-ethnic cohort study.

Background: Social support is associated with higher self-reported physical activity (PA) in postpartum women, but it is unknown if similar association occur when using objective PA data. The aim was to explore the associations between social support and objectively recorded moderate-to-vigorous physical activity (MVPA) postpartum, and if associations differed across ethnic groups.

Methods: We used data from 636 women who participated in the STORK Groruddalen cohort study (2008-2010).

Exploring visual pain trajectories in neck pain patients, using clinical course, SMS-based patterns, and patient characteristics: a cohort study.

Background: The dynamic nature of neck pain has so far been identified through longitudinal studies with frequent measures, a method which is time-consuming and impractical. Pictures illustrating different courses of pain may be an alternative solution, usable in both clinical work and research, but it is unknown how well they capture the clinical course. The aim of this study was to explore and describe self-reported visual trajectories in terms of details of patients' prospectively reported clinical course, their SMS-based pattern classification of neck pain, and patient's characteristics.

The association between different outcome measures and prognostic factors in patients with neck pain: a cohort study.

Background: Health domains like pain, disability, and health-related quality of life are commonly used outcomes for musculoskeletal disorders. Most prognostic studies include only one outcome, and it is unknown if prognostic factors and models may be generic across different outcomes. The objectives of this study were to examine the correlation among commonly used outcomes for neck pain (pain intensity, disability, and health-related quality of life) and to explore how the predictive performance of a prognostic model differs across commonly used outcomes.

Early post-traumatic seizures in hospitalized patients with traumatic brain injury.

Objectives: Early post-traumatic seizures (EPTS) are a well-known complication of traumatic brain injury (TBI). EPTS increase the risk of secondary brain injury and may cause significant challenges during the period of critical care. Routine use of prophylactic anti-seizure medication is controversial due to conflicting reports on efficacy and risk of adverse effects.

Neck and back pain: Differences between patients treated in primary and specialist health care.

Objective: To describe and compare patients with neck and back pain treated by physiotherapists in primary healthcare (PHC) and in departments for physical medicine and rehabilitation in specialist healthcare (SHC) in Norway.

Design: Cross-sectional study using data from the FYSIOPRIM database in PHC and the Norwegian Neck and Back Registry in SHC. Neck and back pain patients in the period 2014-18 aged ≥ 18 years were included.

Bridging troubled water - exploring improvement and patients' experiences using patient-reported outcome measures in physiotherapy: A mixed-method study.

Background And Aims: Increased use of patient-reported outcomes in health care has been emphasized. Our aim was to use the Patient-Specific Functional Scale (PSFS) to examine improvement in neck pain patients' activity limitations during physiotherapy treatment, with the purpose to explore the patients' experiences of using PSFS. The study illuminates whether and how PSFS can be useful in clinical physiotherapy.

The clinical course of neck pain: Are trajectory patterns stable over a 1-year period?

Background: Recent studies with data-driven approaches have established common pain trajectories. It is uncertain whether these trajectory patterns are consistent over time, and if a shorter measurement period will provide accurate trajectories.

Methods: We included 1,124 patients with non-specific neck pain in chiropractic practice.

The Dental stick test - Useful to reveal intra-articular conditions in persons with temporomandibular disorder?

Background: There is a need for clinical tests that can reveal intra-articular conditions in the temporomandibular joint to be able to give proper treatment. The Dental stick test, where participants bite with their molars on a wooden stick, is a pain provocation test for the temporomandibular joint.

Objective: The purpose of this study was to explore if the Dental stick test can be used to reveal intra-articular conditions in the temporomandibular joint in persons with long-lasting painful disorders.

Psychometric properties of the PROMIS-57 questionnaire, Norwegian version.

Purpose: The aims of this cross-sectional study were to explore reliability and validity of the Norwegian version of the Patient-Reported Outcome Measurement System-Profile 57 (PROMIS-57) questionnaire in a general population sample, n = 408, and to examine Item Response properties and factor structure.

Methods: Reliability measures were obtained from factor analysis and item response theory (IRT) methods. Correlations between PROMIS-57 and RAND-36-item health survey (RAND36) were examined for concurrent and discriminant validity.

Prognostic ability of STarT Back Screening Tool combined with work-related factors in patients with low back pain in primary care: a prospective study.

Objective: Primary care screening tools for patients with low back pain may improve outcome by identifying modifiable obstacles for recovery. The STarT Back Screening Tool (SBST) consists of nine biological and psychological items, with less focus on work-related factors. We aimed at testing the prognostic ability of SBST and the effect of adding items for future and present work ability.

Generalized joint hypermobility and risk of pelvic girdle pain in pregnancy: does body mass index matter?

Background: Women with generalized joint hypermobility may be at increased risk of pregnancy-related pelvic girdle pain, but evidence is inconclusive.

Objectives: In this prospective cohort study of 283 pregnant women in Norway, we aimed to study the association of generalized joint mobility with pelvic girdle pain, and to evaluate if pre-pregnancy body mass index was a modifier of the association.

Methods: Generalized joint hypermobility was defined as a score of ≥5/9 positive tests on the Beighton score measured in early pregnancy.

A core outcome set for research and clinical practice in women with pelvic girdle pain: PGP-COS.

Background: Inconsistent reporting of outcomes in clinical trials of women with Pelvic Girdle Pain (PGP) hinders comparison of findings and the reliability of evidence synthesis. A core outcome set (COS) can address this issue as it defines a minimum set of outcomes that should be reported in all clinical trials on the condition. The aim of this study was to develop a consensus-based COS for evaluating the effectiveness of interventions in PGP during pregnancy and postpartum for use in research and clinical practice.

Associations between treatment goals, patient characteristics, and outcome measures for patients with musculoskeletal disorders in physiotherapy practice.

Background: Goal setting is linked to person-centred care and is a core component in physiotherapy, but the associations between goal classes, patient characteristics and outcome measures for musculoskeletal disorders has not been investigated. The study's purpose was to examine 1) how goals used in clinical practice for patients with musculoskeletal disorders (MSD) are distributed in classes based on ICF, 2) if goal classes were associated with patient characteristics and 3) whether goal classes were associated with treatment outcome.

Methods: Data analysis from a longitudinal observational study (N = 2591).

Trunk, pelvic and hip kinematics during the Stork test in pregnant women with pelvic girdle pain, asymptomatic pregnant and non-pregnant women.

Background: Pelvic girdle pain is prevalent during pregnancy, and women affected report weight-bearing activities to be their main disability. The Stork test is a commonly used single-leg-stance test. As clinicians report specific movement patterns in those with pelvic girdle pain, we aimed to investigate the influence of both pregnancy and pelvic girdle pain on performance of the Stork test.

Visual trajectory pattern as prognostic factors for neck pain.

Background: A novel approach capturing both temporal variation and pain intensity of neck pain is by visual trajectory patterns. Recently, both previous and expected visual trajectory patterns were identified as stronger predictors of outcome than traditional measures of pain history and psychological distress. Our aim was to examine patient characteristics within the various previous and expected patterns, relationship between the two patterns and predictive value of a variable combining the previous and expected patterns.
