Abstract [en]

BACKGROUND:Low back pain (LBP) is the leading cause of disability and an increasing sick leave in Denmark. Psychosocial risk factors have been linked to the development of LBP-related disability and work-absenteeism. The short form Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ-sf) was developed to screen for psychosocial risk factors and assess the risk of long-term disability and work-absenteeism.

OBJECTIVE:To translate and cross-culturally adapt ÖMPSQ-sf into Danish and evaluate test-retest reliability with relative and absolute reliability and internal consistency in LBP-patients in a secondary setting.

METHODS:A six-step translation and cross-culturally adaptation process was used. Forty-four patients with subacute and chronic LBP were recruited at an outpatient clinic.

RESULTS:Test-retest reliability (n=𝑛= 37) was found to be excellent (ICC2.1== 0.92), Internal Consistency (n=𝑛= 44) was adequate (Cronbach’s alpha == 0.72). Absolute reliability included Standard Error of Measurement (SEM == 3.97 points), 95% Limits of Agreement (95% LOA == 0.08, −-15.90–15.74), and Smallest Detectable Change (SDC == 10.87 points).

CONCLUSION:The Danish ÖMPSQ-sf showed acceptable measurements properties in subacute and chronic LBP-patients. Further research is needed to assess other measurement properties of the ÖMPSQ-sf, in relation to validity, responsiveness, and the predictive ability before application in research or clinical practice.

Abstract [en]

Musculoskeletal trauma often leads to lasting psychological impacts stemming from concerns of future injuries. Often referred to as kinesiophobia or re-injury anxiety, such concerns have been shown to hinder return to physical activity and are believed to increase the risk for secondary injuries. Screening for re-injury anxiety is currently restricted to subjective questionnaires, which are prone to self-report bias. We introduce a novel approach to objectively identify electrocortical activity associated with the threat of destabilising perturbations. We aimed to explore its feasibility among non-injured persons, with potential future implementation for screening of re-injury anxiety. Twenty-three participants stood blindfolded on a translational balance perturbation platform. Consecutive auditory stimuli were provided as low (neutral stimulus [CS–]) or high (conditioned stimulus [CS+]) tones. For the main experimental protocol (Protocol I), half of the high tones were followed by a perturbation in one of eight unpredictable directions. A separate validation protocol (Protocol II) requiring voluntary squatting without perturbations was performed with 12 participants. Event-related potentials (ERP) were computed from electroencephalography recordings and significant time-domain components were detected using an interval-wise testing procedure. High-amplitude early contingent negative variation (CNV) waves were significantly greater for CS+ compared with CS– trials in all channels for Protocol I (> 521-800ms), most prominently over frontal and central midline locations (P ≤ 0.001). For Protocol II, shorter frontal ERP components were observed (541-609ms). Our test paradigm revealed electrocortical activation possibly associated with movement-related fear. Exploring the discriminative validity of the paradigm among individuals with and without self-reported re-injury anxiety is warranted.

Abstract [en]

Background

Musculoskeletal disorders (MSK) are a global burden causing significant suffering and economic impact. Systematic identification and targeting of research questions of highest interest for stakeholders can aid in improving MSK disorder knowledge and management.

Objective

To obtain Swedish MSK researchers' opinions and views on a collaborative Swedish MSK network (SweMSK) and identify future research areas of importance for Swedish MSK research.

Methods

A web-based survey was conducted July to September 2021 to collect data from 354 Swedish MSK researchers. The survey focused on the need, objectives, and structure of a SweMSK network and identified prioritised areas for future MSK research.

Results

The study included 141 respondents, of which 82 were associate professors or professors. The majority (68%) supported the creation of a new musculoskeletal network. The most supported element was increased collaboration regarding nationwide and multicenter studies. Respondents recommended the creation of a homepage and the establishment of national work groups with different specific interests as the primary elements of a new network.

Conclusion

The results demonstrated a need and desire for increased national research collaboration and the creation of a new musculoskeletal network. The high academic experience and active research participation of the respondents suggest the need for MSK disorder knowledge and management improvement in Sweden. Therefore, the SweMSK network may help facilitate effective collaboration and research efforts that can contribute to the advancement of MSK disorder management and care. This study may provide valuable insights for policymakers, clinicians, and researchers to improve MSK disorder care and management in Sweden.

Abstract [en]

Background: The aims of this study are to 1) determine the scope of musculoskeletal (MSK)-related clinical research in Sweden; 2) collate the amount of first-tier funding received; 3) discuss strategies and infrastructure supporting future MSK clinical trials in Sweden.

Methods: A systematic scoping review protocol was applied in PubMed, Scopus, and SweCRIS databases. The articles were examined, and data were extracted in multiple stages by three blinded authors.

Results: The search strategy resulted in 3,025 publications from 479 Swedish-affiliated authors. Primary health care was the basis for 14% of the publications, 84% from secondary health care, and 2% from occupational health care with a similar proportional distribution of first-tier research grant financing. Approximately one in six publications were randomized controlled trials (RCTs), while the majority were of observational cohort design. The majority of publications in primary and occupational health care were related to pain disorders (51 and 67%, respectively), especially diagnosis, prognosis, and healthcare organizational-related interventions (34%) and rehabilitation (15%) with similar proportional distribution of first-tier research grant financing. In secondary health care, rheumatic inflammatory disorder-related publications were most prevalent (30%), most frequently concerning diagnosis, prognosis, and healthcare organizational-related interventions (20%), attracting approximately half of all first-tier funding. Publications related to degenerative joint disorders (25%), fractures (16%), and joint, tendon, and muscle injuries (13%) frequently concerned surgical and other orthopedic-related interventions (16, 6, and 8%, respectively). Pain disorder-related publications (10%) as well as bone health and osteoporosis-related publications (4%) most frequently concerned diagnosis, prognosis, and healthcare organizational-related interventions (5 and 3%, respectively).

Conclusions: Swedish-affiliated MSK disorder research 2010–2020 was predominantly observational cohort rather than RCT based. There was skewed first-tier funding allocation considering prevalence/incidence and burden of disease. Use of infrastructure supporting register-based RCTs, placebo-controlled RCTs, and hybrid effectiveness-implementation studies on prevention and clinical intervention is important strategies for the future in all healthcare sectors.

Abstract [en]

Objective To systematically review and summarise the evidence for the effects of neuromuscular training compared with any other therapy (conventional training/sham) on knee proprioception following anterior cruciate ligament (ACL) injury.Design Systematic Review.

Data sources PubMed, CINAHL, SPORTDiscus, AMED, Scopus and Physical Education Index were searched from inception to February 2020.

Eligibility criteria Randomised controlled trials (RCTs) and controlled clinical trials investigating the effects of neuromuscular training on knee-specific proprioception tests following a unilateral ACL injury were included.

Data extraction and synthesis Two reviewers independently screened and extracted data and assessed risk of bias of the eligible studies using the Cochrane risk of bias 2 tool. Overall certainty in evidence was determined using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) tool.Results Of 2706 articles retrieved, only 9 RCTs, comprising 327 individuals with an ACL reconstruction (ACLR), met the inclusion criteria. Neuromuscular training interventions varied across studies: whole body vibration therapy, Nintendo-Wii-Fit training, balance training, sport-specific exercises, backward walking, etc. Outcome measures included joint position sense (JPS; n=7), thresholds to detect passive motion (TTDPM; n=3) or quadriceps force control (QFC; n=1). Overall, between-group mean differences indicated inconsistent findings with an increase or decrease of errors associated with JPS by ≤2°, TTDPM by ≤1.5° and QFC by ≤6 Nm in the ACLR knee following neuromuscular training. Owing to serious concerns with three or more GRADE domains (risk of bias, inconsistency, indirectness or imprecision associated with the findings) for each outcome of interest across studies, the certainty of evidence was very low.

Conclusions The heterogeneity of interventions, methodological limitations, inconsistency of effects (on JPS/TTDPM/QFC) preclude recommendation of one optimal neuromuscular training intervention for improving proprioception following ACL injury in clinical practice. There is a need for methodologically robust RCTs with homogenous populations with ACL injury (managed conservatively or with reconstruction), novel/well-designed neuromuscular training and valid proprioception assessments, which also seem to be lacking.

Abstract [en]

Aim: To examine the extent to which sex, country of birth, and functional aspects influence participation in physical education and physical leisure activity among children with cerebral palsy (CP) in Sweden.

Methods: This national cross-sectional registry study included children with CP aged 6 to 18 years who participated in the Swedish national quality registry, the Cerebral Palsy Follow-up Program, CPUP, in 2015. Comparisons and associations between sex, country of birth, and functional aspects and physical leisure/physical education were examined using chi-squared and multivariable logistic regression analysis.

Results: The study included 1935 children. Of them, 1625 (87%) reported participating in physical education and 989 (53%) reported participating in physical leisure activity. Children born in Sweden had higher odds of participating in physical education (OR: 1.99; 95% CI: 1.20-3.28) and physical leisure activity (OR: 2.51; 95% CI: 1.70-3.72) compared with children born outside Europe. Greater impairment of gross motor function was associated with lower participation levels. Boys participated slightly more frequently in leisure activities than girls.

Conclusion: Enhancing social inclusion with regard to disability, birth country, and sex are important and achievable goals for policymakers and practitioners for promoting participation in physical activity for children and adolescents with CP.

Abstract [en]

AIM: The aim of this study was to investigate the distribution of physiotherapeutic interventions for children with Cerebral Palsy in Sweden from an equity perspective, considering sex, country of birth and geographical region.

METHOD: This national cross-sectional registry study includes children with Cerebral Palsy aged 0-18 years who participated in 2015 in the Swedish national quality registry, the Cerebral Palsy follow-up program, CPUP. Comparisons and associations between physiotherapeutic interventions and sex, country of birth and geographical regions were conducted using Chi2 and logistic regression analysis, controlling for cognitive level, level of motor function, age group and dominating symptom.

RESULTS: Of the 2855 participants, 2201 (79%) had received physiotherapy. Children born in Sweden had 1.60 times higher odds (95% CI 1.10-2.33) of receiving physiotherapy compared with children born in foreign countries. Distribution of physiotherapeutic interventions differed significantly between geographical regions. No associations between sex and physiotherapeutic interventions were observed.

CONCLUSION: The results of this study indicate inequity in care in Sweden towards children with Cerebral Palsy born in other counties. Further, physiotherapeutic interventions were not equally distributed in different.

Abstract [en]

Background: Non-specific neck pain has a multifaceted symptom picture and the relationship is obscure between individual improvement on physical function and the neck patient's self-rated status.Purpose: The present aim was to determine the associations between physical test outcomes involving the neck and shoulder region, and self-reported neck symptoms before and after a treatment intervention in women with non-specific neck pain.Methods: Data were obtained for 120 women (aged 20-65) who had participated in a previous randomized controlled trial. Data were used from all participants at baseline for cross-sectional analysis and from 69 women for longitudinal analysis (Change-scores). Associations between self-reported neck problems (pain, disability and symptoms from the neck) and physical test outcomes (Neck-Strength, Cervical Axial-Range of Motion and Peak-Speed of cervical rotation) were estimated with linear regression analyses.Results: Self-rated neck pain was only significantly associated to the physical outcome measure Peak-Speed of cervical rotation, i.e., increased pain related to lower speed. This was true at baseline and for Change-scores at 9 months. Increased neck disability and frequency of symptoms were associated to lower Neck Strength and reduced Peak-Speed at baseline, and to reduced Peak-Speed and Cervical Axial-Range of Motion at 3 and 9 months, respectively. Peak-Speed and Cervical Axial-ROM were thus the physical test outcomes with associations to self-rated changes in neck symptoms. At the 9-month follow-up, 26% of the variance of frequency of symptom changes was explained by changes in Cervical Axial-ROM and Peak-Speed, which were also inter-correlated (r=0.55).Conclusion(s): The results indicate that changes in physical functioning, tested as cervical mobility and strength, have only a modest relation to the course of self-rated condition in neck disorders.Implications: The present study calls for reconsideration regarding acting mechanisms behind the apparent effect of, e.g., strength training on neck pain disorders. The specificity and usefulness of various assessments for decision-making, treatment and evaluation might be questioned.Key-Words: Neck pain, Neck strength, Range of motionFunding acknowledgements: Swedish Council for Working Life and Social Research (2009-1403), AFA Insurance (090288), The Centre for Environmental Research (1152383).Ethics approval: Did this work require ethics approval?:YesInstitution: Regional ethical review board in Uppsala SwedenEthics Committee: Regional ethical review board in Uppsala SwedenEthics number: No 2011/081

Abstract [en]

Background: Cervical strength and stability is often addressed in rehabilitation of people with neck pain. These functions may be associated with emergence and retention of neck pain in cases where the neck strength does not meet daily demands. However, clear empiric support for these notions are lacking, partly due to a scarcity of well controlled dynamometry studies with large samples. First, clarification is needed whether neck strength is in fact reduced in people with neck pain and to resolve the diagnostic performance of neck strength tests.

Purpose: To compare neck muscle strength of women with non-specific long-term neck pain and healthy controls. Also, to assess the diagnostic performance of neck strength tests by assessing their discriminative ability to discern women with and without neck pain.

Methods: The study had a cross-sectional design with data on cervical strength derived from the baseline measurement of a randomized controlled trial (RCT). 80 women with long-term non-specific neck pain (NP) were compared with 40 healthy women (CON). The NP group was a subsample from the RCT selected so that there were no group differences (NP-CON) for body weight and physical activity. Cervical strength assessment included dynamometry of cervico-thoracic extension (CTE) and flexion (CTF) in sitting and cranio-cervical flexion (CCF) in standing, all performed with isometric maximum voluntary contraction (iMVC). Independent samples Mann-Whitney U test and T-test were used to assess group differences for iMVC of the tests. Diagnostic accuracy was further assessed with a receiver operating characteristic (ROC) curve by plotting the true positive rate (sensitivity) as a function of the false positive rate (1 - specificity). The area under the ROC curve (AUC) with 95% confidence interval was used to determine discriminative ability of the tests. The optimal cut-off value to discern NP from CON with corresponding sensitivity and specificity was also determined.

Results: Women with neck pain produced significant lower iMVC in CTE (28%), CTF (26%) and CCF (33%) (all p< 0.001). The ability of CTE, CTF and CCF to discriminate between NP and CON showed moderate accuracy (AUC 0.83, 0.78 and 0.73, respectively). The cut-off value of 165.7 N in CTE had a sensitivity of 0.725 and a specificity of 0.8. The corresponding values for CTF and CCF were 85.8 N (sensitivity 0.8; specificity 0.692) and 4.2 Nm (sensitivity 0.575; specificity 0.9).

Conclusion(s): The neck pain group had less neck muscle strength than controls in all tests. The diagnostic performance of the neck strength tests, judged as discriminative ability to discern neck pain from control participants, were moderate. These results support earlier findings of reduced neck strength in people with neck pain. Also, neck strength tests may have a complementary value in the assessment of neck pain persons.

Implications: The results highlights that impaired neck strength, both in global cervico-thoracic and deep cranio-cervical muscles, is most likely a characteristic of people with long-term neck pain. The study also shows that strength tests could be used with fairly good discriminative precision and may thereby be valuable assessment tools.

Abstract [en]

Objectives To develop predictive models for short-term and long-term clinically important improvement in women with non-specific chronic disabling neck pain during the clinical course of physiotherapy. Design Longitudinal cohort study based on data from a randomised controlled trial evaluating short-term and long-term effects on sensorimotor function over 11 weeks of physiotherapy. Participants and settings Eighty-nine women aged 31-65 years with non-specific chronic disabling neck pain from Gavle, Sweden. Measures The outcome, clinically important improvement, was measured with the Patient Global Impression of Change Scale (PGICS) and the Neck Disability Index (NDI), assessed by self-administered questionnaires at 3, 9 and 15 months from the start of the interventions (baseline). Twelve baseline prognostic factors were considered in the analyses. The predictive models were built using random-effects logistic regression. The predictive ability of the models was measured by the area under the receiver operating characteristic curve (AUC). Internal validity was assessed with cross-validation using the bootstrap resampling technique. Results Factors included in the final PGICS model were neck disability and age, and in the NDI model, neck disability, depression and catastrophising. In both models, the odds for short-term and long-term improvement increased with higher baseline neck disability, while the odds decreased with increasing age (PGICS model), and with increasing level of depression (NDI model). In the NDI model, higher baseline levels of catastrophising indicated increased odds for short-term improvement and decreased odds for long-term improvement. Both models showed acceptable predictive validity with an AUC of 0.64 (95% CI 0.55 to 0.73) and 0.67 (95% CI 0.59 to 0.75), respectively. Conclusion Age, neck disability and psychological factors seem to be important predictors of improvement, and may inform clinical decisions about physiotherapy in women with chronic neck pain. Before using the developed predictive models in clinical practice, however, they should be validated in other populations and tested in clinical settings.
