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]

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]

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.

Abstract [en]

Purpose

This study aimed to identify sub-groups of workers with different trajectories of sick leave due to musculoskeletalpain over 1 year, and to investigate the extent to which the identified trajectories are associated with personal, occupational,lifestyle, and pain-related factors at baseline.

Methods

Data on 981 blue- and white-collar workers were analyzed in the DPHACTO cohort (2012–2014). The numberof days on sick leave due to pain was reported using text messages at 4-week intervals across 1 year. Latent class growthanalysis was used to distinguish sub-groups with different trajectories of sick leave. A web-based questionnaire at baselinewas used to assess personal, occupational (physical and psychosocial), lifestyle, and pain-related factors. Multinomial regressionmodels were constructed to determine associations between baseline factors and trajectories of sick leave (referencingno sick leave), with adjustment for potential confounders.

Results

Four distinct sub-groups were identified, with trajectories of sick leave due to pain ranging from no sick leave(prevalence 76%; average 0.5 days/year) to some days and increasing sick leave due to pain over 1 year (2%; 89 days/year).The increasing trajectory of sick leave was associated with higher perceived physical exertion, more time in manual work,less social community and influence at work, less leisure-time physical activity, smoking, and more severe symptoms (e.g.,multisite pain, low back pain intensity, and pain interference).

Conclusions

We identified four distinct trajectories of sick leave due to musculoskeletal pain. The sub-group with increasingsick leave due to pain was associated with several modifiable physical and psychosocial factors at work and outside work,which may have implications for prevention.

Abstract [en]

Introduction: The aim was to evaluate if pain, disability, and work productivity are influenced by physical and psychosocial work exposures as well as by stress, up to 1 year after a randomized controlled trial treatment intervention, and to determine whether any such association differed between treatment and control groups.

Methods: Ninety-seven working women suffering non-specific neck pain (n = 67 treatment group, n = 30 control group) were followed from end of treatment intervention and at 9- and 15-month follow-ups, respectively. Physical and psychosocial exposures, as well as perceived stress, were assessed after the treatment intervention. Pain, neck disability, and work productivity were assessed at baseline, after intervention 3 months later and at 9- and 15-month follow-ups. Longitudinal assessment was conducted using the exposure level at 3 months as predictor of pain, disability, and work productivity at 3, 9, and 15 months, respectively. Mixed models were used to estimate longitudinal associations, accounting for within-individual correlation of repeated outcome measures by incorporation of a random intercept. Age and duration of neck pain were adjusted for in all models. To evaluate group differences, interactions between exposures and treatment groups were estimated.

Results: High perceived stress was associated with more neck pain, more neck disability, and decreased work productivity in both cross-sectional and longitudinal analyses. High 'control of decision' was associated with less neck pain, less neck disability, and higher work productivity in cross-sectional analyses but only to less disability and higher productivity in longitudinal analyses. Shoulder/arm load was the only physical exposure variable that was significantly associated with work productivity in the univariate analyses. Only small differences were observed between treatment and control groups.

Conclusion: High perceived stress and low 'control of decision' were associated with more neck pain, increased neck disability, and decreased work productivity. Treatment interventions for individuals with neck pain should take into account psychosocial workplace exposures and stress to improve intermediate and long-term results.

Abstract [en]

Sedentary behaviour constitutes a risk for lifestyle related diseases and musculoskeletal pain which does not seem to be compensated for by shorter bouts of high intensity physical activity. A way of tackling this may be long term light intensity physical activity while performing office work.

Aim: Establish the effects of low intensity cycling (LC), moderate intensity cycling (MC) and standing at a simulated office workstation on pain modulation, metabolic expenditure and work performance.

Methods: 36 healthy adults (21 females), mean age 26.8 (SD 7.6) years, partook in this randomized 3x3 cross-over trial with 75 minutes of LC on 20% of maximum aerobic power output (MAP), 30 minutes of MC on 50% of MAP and standing 30 minutes with 48 hours wash-out periods. Outcome measures were pain modulation (pressure- and thermal pain thresholds, (PPT and TPT)), work performance (transcription, mouse pointing and cognitive performance) and metabolic expenditure.

Results: PPTs increased in all conditions. Median increase in PPT trapezius was highest after LC; 39.3 kilopascal (kPa) (15.6;78.6) compared to MC; 17.0 kPa (2.8;49.9) and standing; 16.8 kPa (-5.6;39.4), p=0.015. TPT showed no change. Work performance; compared to standing, transcription was reduced during LC and MC, mouse pointing was faster in LC but had more errors while slower with more errors in MC. Performance in the cognitive task did not differ between conditions. Metabolic expenditure rates differed between all conditions (p<0.001) and were 1.4 (1.3;1.7), 3.3 (2.3;3.7) and 7.5 (5.8;8.7) kilocalories per minute during standing, LC and MC, respectively.

Conclusions: LC seem to be the preferred option since it raised PPTs, more than doubled metabolic expenditure, while minimally influencing work performance when compared to standing. Thus, LC is promising but requires corroboration in field studies.

Abstract [sv]

Besvär ifrån kroppens muskler och leder såsom nack- och ryggbesvär är fortfarande ett stort problem inom arbetslivet. Muskuloskeletal diagnos är den vanligaste orsaken till lång sjukfrånvaro inom privat sektor och näst vanligast inom kommuner och landsting. Orsakerna till dessa besvär kan vara relaterade till exponering både under arbete och på fritid, men även till individfaktorer. Vår forskargrupp har en bred ansats för att fylla kunskapsluckor inom detta område och kommer att presentera resultat från flera forskningsprojekt i symposiet Arbete, individ och nacksmärta.

Långvarigt sittande har blivit alltmer vanligt förekommande i många yrkesgrupper. Långvarigt sittande och låg fysisk aktivitet har också uppmärksammats som ett betydande hälsoproblem i dagens arbetsliv och även som en möjlig riskfaktor för smärta i nacke-skuldra. Men forskningen om betydelsen av långvarigt sittande för smärta i nacke-skuldra är fortfarande begränsad. Likaså är det oklart om huvudets hållning vid sittandet och nackens funktion, exempelvis nackens rörelsefunktion och styrka, har betydelse för besvärsutveckling. Statiskt arbete med nacken i vridna och böjda positioner misstänks vara en riskfaktor för nack-skuldersmärta i yrken såsom tandläkare, men det är oklart varför vissa exponerade individer drabbas medan andra inte får ont. För de med långvarig smärta krävs ofta rehabiliterande åtgärder, och hur väl dessa åtgärder lyckas kan även det vara beroende av individens fysiska och psykosociala arbetsmiljö. Individens arbetsmiljö påverkar således inte bara risken för om man får besvär utan kan också ha betydelse för hur rehabiliteringen av besvären lyckas.

Syftet med detta symposium är att presentera studier från Centrum för belastningsskadeforskning som handlar om nacksmärta i arbetslivet, sammanfatta kunskapsläget inom området och diskutera hur arbetet kan utformas för att bli hållbart och inkluderande. De forskningsexempel som presenteras berör stillasittande och hållning i arbetslivet och dess tänkbara konsekvenser för nacksmärta och hälsa, riskfaktorer för nacksmärta i tandläkaryrket och arbetsmiljöns betydelse för resultatet av rehabilitering vid nacksmärta. Symposiet avslutas med en frågestund och gemensam diskussion.

Abstract [en]

Objective

The purpose of this study was to adapt and evaluate the psychometric properties of the ProFitMap-neck to Brazilian Portuguese.

Methods

The cross-cultural adaptation consisted of 5 stages, and 180 female patients with chronic neck pain participated in the study. A subsample (n = 30) answered the pretest, and another subsample (n = 100) answered the questionnaire a second time. Internal consistency, test-retest reliability, and construct validity (hypothesis testing and structural validity) were estimated. For construct validity, the scores of the questionnaire were correlated with the Neck Disability Index (NDI), and the Hospital Anxiety and Depression Scale (HADS), the Tampa Scale of Kinesiophobia (TSK), and the 36-item Short-Form Health Survey (SF-36).

Results

Internal consistency was determined by adequate Cronbach's α values (α > 0.70). Strong reliability was identified by high intraclass correlation coefficients (ICC > 0.75). Construct validity was identified by moderate and strong correlations of the Br-ProFitMap-neck with total NDI score (–0.56 < R < –0.71) and with the SF-36, HADS-anxiety, HADS-depression, and TSK (–0.32 < R < –0.82). Exploratory factor analysis revealed 2 factors for the Symptom scale: intensity index and the Function scale. Symptom scale–frequency index identified 1 factor. Structural validity was determined by percentage of cumulative variance >50%, Kaiser-Meyer-Olkin index > 0.50, eigenvalue > 1, and factor loadings > 0.2.

Conclusion

Br-ProFitMap-neck had adequate psychometric properties and can be used in clinical settings, as well as research, in patients with chronic neck pain.

Abstract [en]

Background: Cervical range of motion (ROM) is commonly assessed in clinical practice and research. In a previous study we decomposed active cervical sagittal ROM into contributions from lower and upper levels of the cervical spine and found level- and direction-specific impairments in women with chronic non-specific neck pain. The present study aimed to validate these results and investigate if the specific impairments can be explained by the neutral posture (defining zero flexion/extension) or a movement strategy to avoid large gravitationally induced torques on the cervical spine.

Methods: Kinematics of the head and thorax was assessed in sitting during maximal sagittal cervical flexion/extension (high torque condition) and maximal protraction (low torque condition) in 120 women with chronic non-specific neck pain and 40 controls. We derived the lower and upper cervical angles, and the head centre of mass (HCM), from a 3-segment kinematic model. Neutral head posture was assessed using a standardized procedure.

Findings: Previous findings of level- and direction-specific impairments in neck pain were confirmed. Neutral head posture was equal between groups and did not explain the direction-specific impairments. The relative magnitude of group difference in HCM migration did not differ between high and low torques conditions, lending no support for our hypothesis that impairments in sagittal ROM are due to torque avoidance behaviour.

Interpretation: The direction- and level-specific impairments in cervical sagittal ROM can be generalised to the population of women with non-specific neck pain. Further research is necessary to clarify if torque avoidance behaviour can explain the impairments.
