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. The purposes of the present study were: To examine the prevalence of self-reported PGP through pregnancy and early postpartum in a multi-ethnic cohort. To investigate how ethnicity and patient characteristics were associated with risk of PGP during pregnancy and early postpartum. To investigate if clinical and personal factors obtained in gestation week (GW) 15 were associated with PGP in GW28 and postpartum week (PPW) 14. METHODS: This study analyzed questionnaire data from 823 women from the Stork - Groruddalen mult-iethnic cohort study in Norway. Chi-square tests were used to investigate ethnic differences in prevalence of self-reported PGP, and logistic regression analyses to identify factors associated with self-reported PGP. RESULTS: Women from South-Asia and Middle East reported 10-20% higher prevalence of self-reported PGP at all time points compared with Western women. Ethnicity was associated with PGP in GW15 and PPW14, adjusted for parity. Pain locations in pelvic area (PGP locations) in GW15, especially combined symphysis and posterior PGP, gave the highest risk (OR=7.4) for PGP in GW28 and in PPW14 (OR = 3.9). Being multiparous was a risk for PGP in PPW14 (OR=1.9). CONCLUSIONS: Women of South Asian and Middle Eastern background had higher risk of self-reported PGP than Western women. Ethnicity was associated with PGP in GW15 and PPW14, after adjustments for parity. PGP locations in GW15 was the most prominent risk factor for PGP in GW28 and PPW14, whilst ethnicity was not significant in multivariable analyses.

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). MVPA minutes/day in bouts of ≥ 10 minutes was recorded by SenseWear Armband™ Pro3 (SWA) over 7 days, 14 weeks postpartum. Social support for PA from family or friends was measured by a modified 12-item version of the Social Support for Exercise Scale. We used single items, family support mean score (6 items) and friends' support mean score (6-items) in four separate count models, and adjusted for SWA week, age, ethnicity, education, parity, body mass index and time since birth. We tested interactions between social support and ethnicity. Analyses were performed on complete cases and imputed data. RESULTS: Based on imputed data, we observed that women who reported low and high support from family accumulated 16.2 (IQR: 6.1-39.1) and 18.6 (IQR: 5.0-46.5) MVPA minutes/day, respectively. Women who reported low and high support from friends accumulated 18.7 (IQR: 5.9-43.6) and 16.8 (IQR: 5.0-45.8) MVPA minutes/day. We observed a 12% increase in MVPA minutes/day for each additional increase in mean family support score (IRR = 1.12, 95% CI: 1.02 to 1.25). Women reporting high level of support from family on 'discuss PA', 'co-participation' and 'take over chores' accumulated 33%, 37% and 25% more MVPA minutes/day than women reporting low level of support respectively ('discuss PA': IRR = 1.33, 95% CI: 1.03 to 1.72, 'co-participation': IRR = 1.37, 95% CI: 1.13 to 1.66 and 'take over chores': IRR = 1.25, 95% CI: 1.02 to 1.54). Associations were not modified by ethnicity. No statistically significant association between support from friends and MVPA was observed. Similar results were found in complete case analyses, with a few exceptions. CONCLUSION: Overall family support and specific forms of support from family were associated with MVPA across ethnic groups, while support from friends was not associated with MVPA postpartum.

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. The purpose of this study was to expand the understanding of EPTS by examining incidence and risk factors in hospitalized patients with TBI. MATERIAL & METHODS: Adult patients with TBI and evidence of intracranial injury admitted to Oslo University Hospital between 2015 and 2019 were identified from the Oslo TBI Registry - Neurosurgery. Demographic and clinical data including occurrence of seizures were retrieved from the registry. The patients did not receive routine seizure prophylaxis. Univariate and multivariable logistic regression analyses were used to investigate risk factors associated with EPTS. RESULTS: 103 of 1827 patients (5.6%) had new-onset seizures within the first week after TBI. The following factors were in multivariable analyses associated with EPTS; alcohol abuse (odds ratio [OR] 3.6, 95% CI 2.3-5.7, p < .001), moderate and severe brain injury (OR 2.2, 95% CI 1.3-3.8, p = .004 and OR 2.1, 95% CI 1.2-3.6, p = .012), brain contusion (OR 1.6, 95% CI 1.0-2.4, p = .046) and subdural hematoma (OR 1.6, 95% CI 1.0-2.6, p = .052). CONCLUSION: In our material, EPTS occurred in 5.6% of hospital-admitted TBI-patients. Alcohol abuse was the most significant risk factor, followed by moderate and severe brain injury. The results of this study contribute to the discussion about preventive treatment of EPTS in certain risk groups.

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. Factor structure and IRT assumptions were examined with factor analysis methods. IRT Item and model fit and graphic plots were inspected, and differential item functioning (DIF) for language, age, gender, and education level were examined. RESULTS: PROMIS-57 demonstrated excellent reliability and satisfactory concurrent and discriminant validity. Factor structure of seven domains was supported. IRT assumptions were met for unidimensionality, local independence, monotonicity, and invariance with no DIF of consequence for language or age groups. Estimated common variance (ECV) per domain and confirmatory factor analysis (CFA) model fit supported unidimensionality for all seven domains. The GRM IRT Model demonstrates acceptable model fit. CONCLUSIONS: The psychometric properties and factor structure of Norwegian PROMIS-57 were satisfactory. Hence, the 57-item questionnaire along with PROMIS-29, and the corresponding 8 and 4 item short forms for physical function, anxiety, depression, fatigue, sleep disturbance, social participation ability and pain interference, are considered suitable for use in research and clinical care in Norwegian populations. Further studies on longitudinal reliability and sensitivity in patient populations and for Norwegian item calibration and/or reference scores are needed.

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. METHODS: We conducted an observational prospective cohort study with data from patients with neck pain aged 18-84 years consulting Norwegian chiropractors. We used three different outcomes: pain intensity (Numeric Pain Rating Scale), the Neck Disability Index (NDI), and health-related quality of Life (EQ-5D). We assessed associations between change in outcome scores at 12-weeks follow-up with Pearson's correlation coefficient. We used multivariable linear regression models to explore differences in explained variance and relationship between predictors and outcomes. RESULTS: The study sample included 1313 patients and 941 (72%) completed follow-up at 12 weeks. The strongest correlation was between NDI and EQ-5D (r = 0.57) while the weakest correlation was between EQ-5D and pain intensity (r = 0.39). The correlation between NDI and pain intensity was moderate (r = 0.53) In the final regression models, the explained variance ranged from adjusted R2 of 0.26 to 0.60, highest with NDI and lowest with pain intensity as outcome. The predictive contributions of the included predictors were similar across outcomes. Among the investigated predictors, pain patterns and the baseline measure of the corresponding outcome measure contributed the most to explained variance across all outcomes. CONCLUSIONS: The highest correlation was found between NDI and EQ-5D and the lowest with pain intensity. The same prognostic model showed highest predictive performance with NDI as outcome and poorest with pain intensity as outcome. These results suggest that we need more knowledge on the reasons for the differences in predictive performance variation across outcomes.

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). Goals were classified in symptom, function/structure, activity/participation and non-classifiable. Associations between patient characteristics and goal classes were examined using x2 and one-way ANOVA. Association between goal classes and outcomes were examined using multiple logistic and linear regression models. Outcomes are reported at 3 months or end of treatment if prior to 3 months. RESULTS: There was a high variability in goals used for patients with MSD. 17% had symptom goals, 32.3% function/structure, 43.4% activity/participation and 7.4% non-classifiable goals. We found significant associations between goal classes and age, gender, severity, region of pain/diagnosis and emotional distress (all p < .001). Activity/participation goals were associated with better outcomes on GPE (OR 1.80, 95% CI 1.23-2.66). Non-classifiable goal was associated with poorer outcomes on pain intensity (B .87, 95% CI .32-1.43). CONCLUSION: There is an association between goal classes and patient characteristics. Including activity/participation in the main goal was associated with better outcomes for GPE and having a non-classifiable goal was associated with poorer outcomes for pain intensity. TRIAL REGISTRATION: The project is approved by the Regional committee for Medical and Health Research Ethics in Norway (REC no. 2013/2030).  https://clinicaltrials.gov/ct2/show/NCT03626389 .

In the published article, the Table 2 was published incorrectly. The correct Table 2 is given below.

Measuring physical performance in highly active older adults: associations with age and gender?

BACKGROUND: Higher age is associated with reduced physical capability in the general population. The role of age and gender for physical performance in older adults who exercises regularly is, however, not clear, and there is also a lack of recommendations for outcomes to address physical performance for this population. AIMS: To explore the associations between physical performance, age and gender, and to examine the suitability and feasibility of clinical field tests for physical performance in active older adults. METHODS: In this cross-sectional study we included 105 persons, 70-90 years of age, who had exercised regularly for ≥ 12 months. The field tests were Short Physical Performance Battery (SPPB), Timed Up and Go and gait speed for mobility; One-leg standing (OLS) test and Mini-BESTest for balance; Stair test for endurance, 30 s sit-to-stand, and grip strength for muscle strength. RESULTS: We found associations between age and physical performance, and the associations were slightly stronger for women. Men performed better on tests of muscle strength, balance and endurance, while no gender differences were found in mobility. Grip strength was not associated with mobility tests for men. All tests were feasible, while SPPB and OLS had ceiling and floor effects that limit their suitability in this population. CONCLUSIONS: Both age and gender were associated with physical performance. We recommend using the gait speed, Mini-BESTest, 30 s sit-to-stand, grip strength and stair tests to assess physical performance in physically active older adults.

Protocol for the development of a core outcome set for pelvic girdle pain, including methods for measuring the outcomes: the PGP-COS study.

BACKGROUND: Pelvic Girdle Pain (PGP) is an important cause of disability and economic cost worldwide. There is a need for effective preventative and management strategies. Emerging studies measure a variety of outcomes rendering synthesis and translation to clinical practice difficult. A Core Outcome Set (COS) can address this problem by ensuring that data are relevant, useful and usable for making well-informed healthcare choices. The aim of this study is to develop a consensus-based PGP-COS, including agreement on methods (e.g. instruments) for measuring the construct outcomes in the COS for use in research and clinical practice. Furthermore, as there is uncertainty as to whether incorporating stakeholder interviews in addition to conducting a systematic review to determine an initial list of outcomes for the Delphi survey, or, whether using different rating scales in a Delphi survey impacts on the final COS, we propose to embed two methodological studies within the PGP-COS development process to address these questions. METHODS: The PGP-COS study will include five phases: (1) A systematic review of the literature and semi-structured interviews with 15 patients (three countries) to form the initial list of outcomes for the Delphi survey; (2) A 3-round Delphi including patients, clinicians, researchers and service providers; (3) A systematic review of methods for measuring the outcomes in the preliminary PGP-COS identified in the Delphi survey; (4) A face-to-face consensus meeting to agree on the final PGP-COS and methods for measuring the COS; (5) Global dissemination. To address the methodological questions, we will assess the number and type of outcomes, in the final PGP-COS, that were exclusively derived from the interviews. Secondly, we will randomise Delphi survey participants to either a 5-point or 9-point importance rating scale, and examine potential differences in 'important' ratings between the groups. DISCUSSION: There is currently no COS for measuring/monitoring PGP in trials and clinical practice. A PGP-COS will ensure that relevant outcomes are measured using appropriate measurement instruments for patients with PGP globally. CORE OUTCOME SET REGISTRATION: This PGP-COS was registered with COMET (Core Outcome Measures for Effectiveness Trials) in January 2017 ( http://www.comet-initiative.org/studies/details/958 ).

Characteristics, course and outcome of patients receiving physiotherapy in primary health care in Norway: design of a longitudinal observational project.

BACKGROUND: Physiotherapists (PTs) in primary health care manage patients with large variation in medical diagnosis, age, functional status, disability and prognosis. Lack of knowledge and systematically collected data from patients treated by PTs in primary health care has prompted this longitudinal observational physiotherapy project. This paper aims to describe a method for developing a database of patients managed by PTs in primary health care, with the main purpose to study patients' characteristics, treatment courses and prognostic factors for favourable outcome. METHODS: This is a longitudinal observational project, following patients through their physiotherapy treatment periods in primary health care in Norway and until one year after inclusion. The project involves both private practitioners and municipally employed PTs working in primary health care in nine municipalities in Norway. The patients are recruited to three different cohorts depending on age and whether they are referred to a private practitioner or a municipally employed PT. All data are recorded electronically, transferred and stored securely. For all patients we have included extensive questionnaires to obtain information about demographics, disability and function, pain-related variables, psychosocial factors, treatments and evaluation of treatment as well as response to clinical tests. The PTs have access to use their own patients' data. We have also prepared for linkage to national patient registers and data collected in population-based studies to be able to gather further important data. DISCUSSION: This project will have important implications for physiotherapy services in primary health care. The database contains more than 3000 patients, and data collection is ongoing. Data collected so far suggest that the patients included are representative of the larger population of patients treated by private practitioners or municipally employed PTs in Norway. This large scale prospective physiotherapy project will provide knowledge about the patient groups, applied treatments and short- and long-term outcome of the patients.

Dynamic balance in patients with degenerative lumbar spinal stenosis; a cross-sectional study.

BACKGROUND: Degenerative lumbar spinal stenosis (LSS) is a prevalent condition in adults over the age of 55 years. The condition is associated with activity limitations that are related to increased pain when engaging in weight-bearing activities, such as walking and standing, and release of pain while sitting down or bending forward. The limitation on ambulation is also associated with impaired balance although the types of balance problems are sparsely described in this patient group. The purpose of this study was to assess dynamic balance in persons with LSS by the Mini-BESTest and explore the associations with self-reported balance and functional disability. METHODS: Sixty two participants were included in this cross-sectional study. The main outcome measure was the Mini-BESTest, providing a total score and sub-scores for 4 balance control systems (Anticipatory Adjustment, Reactive Response, Sensory Orientation, Stability of Gait). The Swiss Spinal Stenosis Questionnaire provided sub-scores for self-reported balance problems and walking function (FUNC). RESULTS: The participants showed large inter-individual variation in all measures of balance. The Mini-BESTest score ranged from very good to poor and the mean value was 22.8 (SD 3.5). Nineteen participants (31%) reported having frequent balance problems. Logistic regression analyses showed that both the total Mini-BESTest score (OR (95% CI) 1.6 (1.2, 2.0)(P = .001) and 3 of the 4 balance control systems (Anticipatory Adjustment, Sensory Orientation, Stability in Gait) were significantly associated with self-reported balance problems (.001 ≤ P ≤ .01). The strongest association was seen between Sensory Orientation and balance problems, implying that it is 4.4 times more likely that persons would have no or occasional balance problems with each unit of increase in Sensory Orientation. The total score for the Mini-BESTest was significantly associated with FUNC (P = .042). CONCLUSIONS: The dynamic balance of persons with LSS showed a large heterogeneity with a large fraction of the participants displaying no balance impairments. The test results were associated with the participants' self-reported balance problems and walking function. The Mini-BESTest thus appears to provide additional information to self-reported disability, and by identifying different kind of balance control impairments, the Mini-BESTest could be useful for physiotherapists working with person-centered rehabilitation in persons with LSS.

Reliability and screening ability of the StarT Back screening tool in patients with low back pain in physiotherapy practice, a cohort study.

BACKGROUND: Low back pain (LBP) is the most common reported musculoskeletal disorder, with large prevalence numbers and high costs. Focus on early identification of patients at risk of developing chronic LBP has increased. The Keele Start Back Tool (SBT) is a questionnaire aiming at screening prognostic indicators in LBP patients, categorizing patients into risk-groups and guide treatment. The aim of this study was to explore the Norwegian version of the SBT with regard to reliability of the SBT-scoring and the screening ability in LBP patients in primary care physiotherapy. METHODS: LBP patients answered a package of questionnaires twice, with 1-3 days in between, containing SBT, Hannover functional ability questionnaire, pain intensity questions and demographics. The relative and absolute reliability of SBT was calculated using intraclass correlation coefficient (ICC) and the smallest detectable change respectively. Independent sample t-tests were used for group comparisons. RESULTS: Fifty-two patients with LBP. Mean age (SD) was 45 (12) years and 62% were female. The ICC (95% CI) for SBT total score and psychosocial subscore was 0.89 (0.82, 0.94) and 0.82 (0.70, 0.90) respectively. None of the participants were allocated to the high risk group. The medium risk group reported significantly more pain last week and more activity limitations than the low risk group at both test and retest (0.001 ≤ p ≤ 0.003), whereas no significant difference between the groups was found on pain now (0.05 ≤ p ≤ 0.16). CONCLUSIONS: The Norwegian version of the SBT was reliable and the screening ability was good as the subgrouping of patients into risk-groups reflected the severity of their back problems. The SBT may be an applicable and useful tool in physiotherapy practice.

Inter-tester reliability of selected clinical tests for long-lasting temporomandibular disorders.

OBJECTIVE: Clinical tests used to examine patients with temporomandibular disorders vary in methodological quality, and some are not tested for reliability. The purpose of this cross-sectional study was to evaluate inter-tester reliability of clinical tests and a cluster of tests used to examine patients with long-lasting temporomandibular disorders. METHODS: Forty patients with pain in the temporomandibular area treated by health-professionals were included. They were between 18-70 years, had 65 symptomatic (33 right/32 left) and 15 asymptomatic joints. Two manual therapists examined all participants with selected tests. Percentage agreement and the kappa coefficient (k) with 95% confidence interval (CI) were used to evaluate the tests with categorical outcomes. For tests with continuous outcomes, the relative inter-tester reliability was assessed by the intraclass-correlation-coefficient (ICC3,1, 95% CI) and the absolute reliability was calculated by the smallest detectable change (SDC). RESULTS: The best reliability among single tests was found for the dental stick test, the joint-sound test (k = 0.80-1.0) and range of mouth-opening (ICC3,1 (95% CI) = 0.97 (0.95-0.98) and SDC = 4 mm). The reliability of cluster of tests was excellent with both four and five positive tests out of seven. CONCLUSION: The reliability was good to excellent for the clinical tests and the cluster of tests when performed by experienced therapists. The tests are feasible for use in the clinical setting. They require no advanced equipment and are easy to perform.

Fatigue in adults with Marfan syndrome, occurrence and associations to pain and other factors.

This study aims to investigate how fatigue affects adults with verified Marfan syndrome (MFS) in their daily lives, by examining fatigue levels and prevalence of severe fatigue compared to the general Norwegian population and individuals with other comparable chronic conditions. We investigated associations between socio-demographic characteristics, Marfan-related health problems, pain and fatigue. A cross-sectional study was conducted, using a postal questionnaire including the Fatigue Severity Scale (FSS) and questions on socio-demographic characteristics, Marfan-related health problems and pain. One hundred seventeen persons with MFS were invited to participate, 73 answered (62%). Participants reported significantly higher FSS scores and prevalence of severe fatigue compared to the general Norwegian population and patients with rheumatoid arthritis (RA), but lower than for other chronic conditions. Participants with chronic pain reported higher fatigue scores than those without chronic pain. Participants on disability benefits reported higher fatigue scores than participants who were working or enrolled in higher education. Marfan-related health problems like aortic dissection and use of blood pressure medication were not significantly associated with fatigue. In multivariable regression analyses chronic pain and employment status were significantly associated with fatigue. The final multivariable model explained 24% of the variance in fatigue scores. Our results show that fatigue is common in MFS patients and that it interferes with their daily lives. Chronic pain and employment status show significant associations to fatigue. This implies that fatigue is important to address when meeting MFS patients in clinical practice. There is need for more research on fatigue in Marfan syndrome.

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. We investigated the associations between (a) contact with ethnic Norwegians and (b) Norwegian language skills and. No associations were observed in pregnancy. Postpartum, women who reported contact with ethnic Norwegians accumulated 17 MVPA min/day (95% CI: -.60, 34.54) more than women with no contact. In complete case analyses, this difference was significant (27 MVPA min/day (95% CI: 8.60, 44.54)). In early postpartum women with contact with ethnic Norwegians seems to be more physically active than women without contact. No associations were observed in pregnancy.

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. METHODS: We performed a prospective, noninferiority study on 149 patients with Weber B ankle fractures and stable weight-bearing radiographs. Gravity stress radiographs classified fractures as stable (SER2 [n = 88]) or partially unstable (SER4a [n = 61]). All were treated with a functional orthosis and weight-bearing was allowed; patients were followed for 2 years. The primary outcome was the Manchester-Oxford Foot and Ankle Questionnaire (MOXFQ), with a range from 0 to 100, in which lower scores indicate fewer symptoms. A noninferiority margin was prospectively defined as 7.5 points. The secondary outcomes included the Olerud-Molander Ankle Score, assessment of ankle congruence, and treatment-related adverse events. RESULTS: The primary outcome data were available for 144 (96.6%) of 149 participants at 2 years. The between-group difference in the MOXFQ score was 1.0 point (95% confidence interval, -1.4 to 3.4 points; p = 0.397) in favor of the SER2 group, consistent with noninferiority. We found no appreciable between-group differences for any other outcome. CONCLUSIONS: In Weber B/SER ankle fractures that are stable on weight-bearing radiographs, are treated with removable orthoses, and are allowed to bear weight, a concomitant unstable gravity stress test (SER4a) was not associated with worse patient-reported or radiographic outcomes compared with a stable gravity stress test (SER2) at the 2-year follow-up. Thus, the identification of stress instability seems redundant, which questions the applicability of stress instability for surgical decision-making. LEVEL OF EVIDENCE: Diagnostic Level II .

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. Intraclass correlation coefficient (ICC3.1) was used to assess test-retest reliability and Cronbach's α for internal consistency. The validity of the questionnaires was also assessed. RESULTS: A total of 39 adults with DM1 were included. We found excellent test-retest reliability on ABILHAND-NMD (ICC 0.91) and ACTIVLIM (ICC 0.93). We found a good internal consistency of ABILHAND-NMD with Cronbach's α (95%CI) of 0.80 (0.69-0.88) and ACTIVLIM with Cronbach's α (95%CI) of 0.88 (0.82-0.93) An expert group of healthcare professionals and a pilot group reported good face and content validity. We found a high correlation between ABILHAND-NMD and ACTIVLIM (r = 0.75), p < 0.001 implying good convergent validity. ABILHAND-NMD and ACTIVLIM showed no floor effect, but a potential for ceiling effect. CONCLUSION: The Norwegian versions of ABILHAND-NMD and ACTIVLIM are reliable and valid patient reported outcome measures for Myotonic Dystrophy type 1. The questionnaires are easy to administer as they take a short time to answer, and the participants reported no problems understanding the questions.

Myotonic Dystrophy type 1 cause myopathy and altered muscle function.Impaired arm- and hand function increases patients' need for assistance and reduces independence.The use of patient reported outcome measures (PROMs) to uncover impairments and activity limitations is important in clinical practice and research.The Norwegian versions of ABILHAND-NMD and ACTIVLIM are reliable and valid measures of manual ability and activity limitations for adults with Myotonic Dystrophy type 1.

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. The chiropractors treated their patients as per usual, and for this study, baseline data and 4-week follow-up data were used. Patient data included the clinical indicators (1) previous episodes of neck pain, (2) a history of long duration neck pain and (3) improvement four weeks after initial treatment. The recruiting chiropractors were asked at 4-week follow-up if each patient was recommended continued care, defined as care planned beyond the first 4 weeks. Univariate and multivariable logistic regression models investigated the association between clinical indicators and the continued care recommendation, as well as the influence of chiropractor characteristics on this recommendation. Cross tabulations investigated the relationship between the number of indicators present and recommendation of continued care. RESULTS: Long duration of neck pain was the strongest clinical indicator for being recommended continued care 4 weeks after the initial treatment. Chiropractor characteristics were not associated with this recommendation. In patients with all three clinical indicators present, 39% were recommended continued care. When two and one indicators were present, the percentages of those recommended continued care were 25% and 10%, respectively. CONCLUSION: Chiropractors recommended continued care for patients experiencing neck pain based on their history of long pain duration, and this was not influenced by characteristics of the chiropractor. This differs from previous studies of indicators for maintenance care in patients with low back pain.

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. METHODS: Six patients participated. A mixed-method study design was applied, triangulating ontological perspectives of realism and phenomenology, quantitative and qualitative methods. Single Subject Experimental Design with PSFS as outcome measure examined changes over time and phenomenological interviews examined its meaningfulness for patients. Patients defined their personal activity limitations due to neck pain and scored difficulties several times, during the physiotherapy treatment period, using PSFS. We used visual analyses of the quantitative data and thematic analyses of the qualitative data. Integration and combination of the results from the two designs are presented in the discussion. RESULTS: In the quantitative analyses, PSFS showed improvement in most activity limitations during treatment. The qualitative analyses revealed that using PSFS required the patient to engage in different bodily awareness processes and handle the dilemma of a possible double function of scoring chosen activities. The mixed findings revealed improved functionality and that the context and the interaction between patient and therapist have a significant influence on the assessment process. CONCLUSIONS: To be able to improve the utilization of PSFS, communication between patients and physiotherapists is of vital importance. When using PSFS, physiotherapists should direct their attention to the importance of interaction as always present and vital in assessments.
