Musculoskeletal symptoms in a local community

Long COVID quality of life and healthcare experiences in the UK: a mixed method online survey

PURPOSE

The complexity of long COVID and its diverse symptom profile contributes to unprecedented challenges for patients, clinicians, and healthcare services. The threat of long COVID remains ignored by Governments, the media and public health messaging, and patients' experiences must be heard through understanding of the lived experience. This study aimed to understand the lived experience of those living with long COVID.

METHODS

An online web-based survey was designed using Patient and Public Involvement and Engagement (PPIE) to increase understanding of the lived experiences of long COVID, and was distributed through PPIE groups, social media, and word of mouth. The survey used closed and open questions relating to demographics, pre- and post-COVID-19 health quality of life, daily activities and long COVID experiences.

RESULTS

Within our sample of 132 people living with long COVID, the findings highlight that individuals are being severely impacted by their symptoms and are unable to or limited in participating in their daily activities, reducing quality of life. Long COVID places strain on relationships, the ability to live life fully and is detrimental to mental health. Varying health care experiences are described by participants, with reports of medical gaslighting and inadequate support received.

CONCLUSIONS

Long COVID has a severe impact on the ability to live life fully, and strains mental health. The appropriate mechanisms and support services are needed to support those living with long COVID and manage symptoms.

What Are the Most Important Problems in Functioning Among Patients With Shoulder Pain? An Analysis of the Patient-Specific Functional Scale

OBJECTIVE

The purpose of this study was to identify important functional problems among individuals with shoulder pain using the Patient-Specific Functional Scale (PSFS) and to investigate differences between individuals receiving primary care and individuals receiving secondary care.

METHODS

In this cross-sectional study located in a primary and secondary care outpatient clinic, a total of 177 individuals seeking care for shoulder pain (84 from primary care and 93 from secondary care) were recruited. Background variables, pain, physical activity, and PSFS responses were collected using a questionnaire software package. Meaningful concepts were linked from the PSFS responses to the International Classification of Functioning, Disability and Health (ICF) according to established rules. Frequencies for the ICF categories were estimated separately for primary care and secondary care. Differences between primary care and secondary care were investigated by calculating CIs for the sample proportions at ICF chapter level.

RESULTS

The primary care sample reported functional problems linked to 226 ICF categories, whereas the secondary care sample reported functional problems linked to 337 ICF categories. Of the linked ICF categories, 87.7% belonged to the Activities and Participation component of the ICF. Seventeen categories were identified in >3% of the individuals; of those, the most frequent categories were recreation and leisure, lifting and carrying objects, doing housework, hand and arm use, and remunerative employment. Categories included in the ICF chapters of self-care and domestic life were significantly more frequent in the secondary care sample, whereas there was a trend that neuromusculoskeletal and movement-related functions were more frequent in primary care.

CONCLUSION

The present findings indicate that individuals with shoulder pain report a wide range of functional problems, from basic functions related to mobility to activities related to work and leisure. This study also discovered differences between patients in primary care and secondary care. The large variation in the experiences between people supports the use of an individualized measure in assessments.

IMPACT

This study adds new knowledge about problems in functioning among people with shoulder pain and how the individual experience varies between primary care and secondary care settings. Moreover, the content analyses used in this study showed the full potential of the ICF classification and should have potential for further application.

A randomised controlled trial comparing the effectiveness of surgical and nonsurgical treatment for cervical radiculopathy

Background

Cervical radiculopathy is usually caused by disc herniation or spondylosis. The prognosis is expected to be good in most patients, but there is limited scientific evidence on the indications for nonsurgical and surgical treatments. The aim of the present study is to evaluate and compare the effectiveness of surgical and nonsurgical treatment in two trials – including disc herniation and spondylosis, respectively, and to evaluate factors that contribute to better decision making.

Methods/design

Patients with disabling radicular arm pain and MRI-proven cervical disc herniation or spondylosis will be randomised to receive nonsurgical or surgical treatment. The follow-up period is one year and the sample size is estimated to be 50 for each arm in the two trials, giving a total of 200 patients. The primary outcomes are the Neck Disability Index and arm pain. Secondary outcomes include neck pain; EQ-5D and costs to evaluate cost-effectiveness; prognostic factors; CT and MRI scans, to estimate intervertebral foraminal area and nerve root compression; and the expected minimal improvement for willingness to undergo treatment.

Discussion

The outcomes of this study will contribute to better decision making in the treatment of cervical radiculopathy.

This study has been registered at ClinicalTrials.gov as NCT03674619, on September 17, 2018.

Broad External Validation and Update of a Prediction Model for Persistent Neck Pain After 12 Weeks

STUDY DESIGN

A prospective observational study.

OBJECTIVE

To externally validate the prediction model developed by Schellingerhout and colleagues predicting global perceived effect at 12 weeks in patients with neck pain and to update and internally validate the updated model.

SUMMARY OF BACKGROUND DATA

Only one prediction model for neck pain has undergone some external validation with good promise. However, the model needs testing in other populations before implementation in clinical practice.

METHODS

Patients with neck pain (n = 773) consulting Norwegian chiropractors were followed for 12 weeks. Parameters from the original prediction model were applied to this sample for external validation. Subsequently, two random samples were drawn from the full study sample. One sample (n = 436) was used to update the model; by recalibration, removing noninformative covariates, and adding new possible predictors. The updated model was tested in the other sample (n = 303) using stepwise logistic regression analysis. Main outcomes for performance of models were discrimination and calibration plots.

RESULTS

Three hundred seventy patients (47%) in the full study sample reported persistent pain at 12 weeks. The performance of the original model was poor, area under the receiver operating characteristics curve was 0.55 with a Confidence Interval of 0.51-0.59. The updated model included Radiating pain to shoulder and/or elbow, education level, physical activity, consultation-type (first- time, follow-up or maintenance consultation), expected course of neck pain, previous course of neck pain, number of pain sites, and the interaction term Physical activity##Number of pain sites. The area under the receiver operating characteristics curve was 0.65 with a 95% Confidence Interval of 0.58-0.71 for the updated model.

CONCLUSION

The predictive accuracy of the original model performed insufficiently in the sample of patients from Norwegian chiropractors and the model is therefore not recommended for that setting. Only one predictor from the original model was retained in the updated model, which demonstrated reasonable good performance predicting outcome at 12 weeks. Before considering clinical use, a new external validation is required.

Prevalence of musculoskeletal pains and effect of work-related factors among employees on offshore oil and gas installations in Iran

BACKGROUND

Work-related musculoskeletal pain is usually caused by poor physical conditions, repetitive motion, and adverse environmental and psychological situations.

OBJECTIVE

This study aims to assess the prevalence of musculoskeletal pain and their work-related factors among employees on offshore oil and gas installations in Iran.

METHODS

Standardized Nordic Questionnaire was used to collect data. The relationship of musculoskeletal pain with job type, rest breaks, exercise, shift program, and work period was studied among employees on offshore installations. T-test and ANOVA were used for data analysis.

RESULTS

Employees on offshore installations were exposed to high levels of risk of musculoskeletal pain in their knees and back. Consequently, they reported the highest level of complaints of pain in the neck and lower back areas. Workers in drilling and tour-scheduling jobs reported the highest level of musculoskeletal pain. In the course of seven days and 12 months, the highest level of significant relationship was observed between the limbs and the work periods (tour scheduling or days-off) of the staff.

CONCLUSION

The findings showed that the prevalence of musculoskeletal disorders among employees of offshore facilities was high due to inappropriate working conditions such as repetitive work, lifting heavy loads and limited rest periods. Therefore, strategies must be considered to reduce the effects of disorders.

Sleep problems: a predictor of long-term work disability?

Aims: This study investigates sleep problems as a predictor of long-term work disability. Methods: Data from a community-based four-year prospective study were used. In 1990, all inhabitants of the municipality of Ullensaker, Norway, belonging to six age cohorts (20-22, 30-32, 40-42, 50-52, 60-62, and 70-72 years), were mailed a questionnaire .Of the 1,788 responders who were working and not older than 62 years, 1,426 ( 80%) returned a second questionnaire four years later ( 1994) . Results: Reporting mediocre or poor sleep ( in contrast to good) in 1990 was significantly related to long-term work disability ( > 8 weeks) during the previous 12 months in 1994 ( odds ratio=2.16; 95% confidence interval=1.26-3.72) , after adjustments for age, gender, civil status, body mass index, emotional symptoms, musculoskeletal pain, self-evaluated health, smoking, physical exercise, job satisfaction, and work characteristics . Conclusion: The study indicates that sleep problems are a predictor of long-term work disability.

Marital disruption and long-term work disability

Data from a community-based four-year prospective study were used to investigate the relationship between marital disruption and long-term work disability. In 1990, all inhabitants of the municipality Ullensaker, Norway, belonging to six cohorts (20-22 years, 30-32 years, 40-42 years, 50-52 years, 60-62 years and 70-72 years) were sent a questionnaire. Of the 1,359 respondents who were working, married or cohabiting, and not older than 62 years, 1,115 (82%) returned a second questionnaire four years later (1994). Separation or divorce between 1990 and 1994 was related to long-term work disability in 1994 (OR=3.02; 95% CI: 1.57-5.81), even after adjustments for age, sex, work characteristics, number of work hours per week, job satisfaction, body mass index, having pre-school children, smoking, physical leisure activity, emotional symptoms and musculoskeletal pain (all measured in 1990). Emotional problems evoked by the marital disruption may be part of the explanation.

Is radial Extracorporeal Shock Wave Therapy (rEWST) combined with supervised exercises (SE) more effective than sham rESWT and SE in patients with subacromial shoulder pain? Study protocol for a double-blind randomised, sham-controlled trial

Background

Subacromial shoulder pain is a common complaint. Radial Extracorporeal Shock Wave Therapy (rESWT) has being increasingly used to treat calcific and non-calcific tendinosis, although there is no evidence of the effectiveness of rESWT in non-calcific tendinosis of the rotator cuff. A randomised single blind study showed that the short-term effect of supervised exercises (SE) was significantly better than rESWT on subacromial shoulder pain, but both groups improved. In a clinical trial on achilles tendinopathy rESWT improved the effectiveness of treatment with eccentric loading. The objective of this present study is to evaluate if rESWT in addition to SE is more effective in improving shoulder pain and function compared with sham rESWT and SE in patients with subacromial shoulder pain.

Methods/Design

This is a double blind, randomised sham-controlled trial which is performed at the shoulder clinic at the Department of Physical Medicine and Rehabilitation in Oslo University Hospital, Norway. One-hundred-forty-four patients with subacromial shoulder pain lasting at least 3 months, age from 25 to 70 years old are included in the trial. Patients are randomly allocated in 1:1 ratio to receive either rESWT or sham rESWT once a week in addition to SE once a week for the initial 4 weeks. Subsequently SE are provided twice a week for 8 weeks. The primary outcome measure is a change in the Shoulder Pain and Disability Index (SPADI) at 24 weeks follow-up. Secondary outcomes include return to work, pain at rest and on activity, function, and health related quality of life. The patients, the physiotherapist providing the exercise regimen and the outcome assessor are blinded to group assignment. The physiotherapist providing the rESWT is not blinded.

Discussion

Because of the extensive use of rESWT in the treatment of subacromial shoulder pain the results of this trial will be of importance and have impact on clinical practice.

Musculoskeletal disorders in Norway: prevalence of chronicity and use of primary and specialist health care services

BACKGROUND

Uncertainty exists with regards to the extent of prevalence and health care use for musculoskeletal disorders in Norway. The aim of this study was to estimate the prevalence of chronic musculoskeletal disorders and to estimate the prevalence of persons receiving primary and specialist health services for these disorders.

METHODS

We used three data-sources. First, four discrete years of the nationally representative cross-sectional Survey of Health and Living Conditions (SHLC) conducted in 2002, 2005, 2008 and 2012 by Statistics Norway. Second, we used the Norwegian Patient Registry (NPR) to estimate the proportion of the population who used specialist health services in 2012. Third, we used the national register dataset for reimbursement of primary care physicians, chiropractors and physiotherapists (KUHR) to estimate the proportion of the population attending primary care physicians, chiropractors or physiotherapists in 2012. Age- and sex-specific prevalence/utilization estimates for musculoskeletal disorders were calculated.

RESULTS

In 2012, 18% of men and 27% of women reported musculoskeletal disorders lasting for six months or more in the SHLC. Primary health care services reimbursed for musculoskeletal disorders were used by 37% of women and 30% of men. Of these 32% (women) and 26% (men) were physician contacts and between 5 and 9% physiotherapist or chiropractor or combined contact types. Corresponding numbers for specialist services were 5% in men and 7% in women, where the majority was out-patient consultations. Low back and neck pain were the most common diagnoses both in the general population and as reason for health care utilization. We found that musculoskeletal disorders increased with age, however our results showed no variation in prevalence of chronic disorders between 2002 and 2012.

CONCLUSION

Chronic musculoskeletal disorders were common in the general population, with higher prevalence among women compared to men, and increasing prevalence with age. Musculoskeletal disorders had considerable impact on the use of primary and specialist health services in Norway. The use of register data on health service utilization may be a useful source for monitoring population trends, and for estimating the burden in terms of health and health service use.

Antiphospholipid (Hughes) syndrome: description of population and health-related quality of life (HRQoL) using the SF-36

Objective

Antiphospholipid (Hughes) syndrome (APS) affects mainly women 15 to 50 years of age and is responsible for approximately 20% of strokes in people <40 years. Little is known about the psychological burden of this long-term condition. We investigated HRQoL in APS.

Methods

We conducted a cross-sectional survey involving 270 members of the Hughes Syndrome Foundation worldwide. Data included HRQoL (SF-36), demographics, and APS-related self-reported major issues. Response rate was 60%.

Results

T-tests indicated significantly worse mean scores for seven of the eight domains of the SF-36 in secondary antiphospholipid syndrome (SAPS) compared to primary antiphospholipid syndrome (PAPS), e.g. bodily pain t(263) = 6.10 p < 0.001 except for mental health t(267) = 1.95 p = 0.053. PAPS appeared to be associated with poorer HRQoL in most mental health domains but overall better physical domains compared to systemic lupus erythematosus (SLE) alone. SAPS appeared to have a more adverse impact on HRQoL compared to PAPS and SLE. Major issues identified: pain and fatigue, lack of health care professional/public awareness, and medication unpredictability.

Conclusion

HRQoL in PAPS appears to be generally better than SLE and SAPS in physical domains, but poorer in mental domains. APS patients might need more social support in terms of information and awareness of the condition to improve their coping strategies.

Hand, hip and knee osteoarthritis in a Norwegian population-based study--the MUST protocol

BACKGROUND

Knowledge about the prevalence and consequences of osteoarthritis (OA) in the Norwegian population is limited. This study has been designed to gain a greater understanding of musculoskeletal pain in the general population with a focus on clinically and radiologically confirmed OA, as well as risk factors, consequences, and management of OA.

METHODS/DESIGN

The Musculoskeletal pain in Ullensaker STudy (MUST) has been designed as an observational study comprising a population-based postal survey and a comprehensive clinical examination of a sub-sample with self-reported OA (MUST OA cohort). All inhabitants in Ullensaker municipality, Norway, aged 40 to 79 years receive the initial population-based postal survey questionnaire with questions about life style, general health, musculoskeletal pain, self-reported OA, comorbidities, health care utilisation, medication use, and functional ability. Participants who self-report OA in their hip, knee and/or hand joints are asked to attend a comprehensive clinical examination at Diakonhjemmet Hospital, Oslo, including a comprehensive medical examination, performance-based functional tests, different imaging modalities, cardiovascular assessment, blood and urine samples, and a number of patient-reported questionnaires including five OA disease specific instruments. Data will be merged with six national data registries. A subsample of those who receive the questionnaire has previously participated in postal surveys conducted in 1990, 1994, and 2004 with data on musculoskeletal pain and functional ability in addition to demographic characteristics and a number of health related factors. This subsample constitutes a population based cohort with 20 years follow-up.

DISCUSSION

This protocol describes the design of an observational population-based study that will involve the collection of data from a postal survey on musculoskeletal pain, and a comprehensive clinical examination on those with self-reported hand, hip and/or knee OA. These data, in addition to data from national registries, will provide unique insights into clinically and radiologically confirmed OA with respect to risk factors, consequences, and management.

Shoulder pain in Iranian elite athletes: the prevalence and risk factors

OBJECTIVE

Shoulder sports injuries are relatively common in athletes who perform highly repetitive motions. The purposes of this study were to determine the prevalence of and risk factors for shoulder injuries and to analyze how individual and other sport characteristics contribute to the risk of shoulder injuries among 6 overhead sports, those being swimming, rowing, wrestling, basketball, volleyball, and handball.

METHODS

A cross-sectional study was carried out on 613 Iranian overhead sports athletes in different collegiate sport fields. Data were collected using different questionnaires. A structured questionnaire including demographics, sport characteristics, and also prevalence and risk factors of shoulder pain was used. Visual analogue scale and Disability of the Arm, Shoulder, and Hand questionnaires were used to determine the pain intensity and functional disability, respectively.

RESULTS

Point, last 6-month, last year, and lifetime prevalences of shoulder pain were 21.4%, 29%, 38.8%, and 41.6%, respectively. The highest point prevalence was related to the rowing athletes with 31.9% and the lowest for swimming athletes (12.3%). Sex, body mass index, sport level, days of practice per week, and satisfaction with income were found to be significantly correlated with the prevalence of shoulder pain (P < .05 in all instances). For those with shoulder pain, the mean pain intensity and functional disability were 53.8 mm and 15.46%, respectively.

CONCLUSIONS

The prevalence of shoulder pain in athletes with highly repetitive overhead motions seems to be high.

The population prevalence of foot and ankle pain in middle and old age: a systematic review

A systematic review and meta-analysis of population-based epidemiological studies was undertaken to determine the prevalence of foot and ankle pain in middle and old age. Searches were conducted in the following electronic databases from inception to October 2010: PubMed, EMBASE, AMED, CINAHL, Cochrane, PEDro, and SportDiscus. Full-text English language articles were included if they used population sample frames, cross-sectional design or analysis, and reported prevalence estimates for foot and/or ankle pain in adults aged 45 years and over. Thirty-four articles from 31 studies involving 75,505 participants provided 529 prevalence estimates based on different case definitions and population strata. Random-effects meta-analyses of studies with comparable case definitions provided pooled prevalence estimates, for frequent foot pain of 24% (95% confidence interval 22-25%; n=3; I(2)=46%) and for frequent ankle pain of 15% (95% confidence interval 13-16%; n=2; I(2)=0). Small sample sizes and low response rates in some studies, together with heterogeneous case definitions, limit confident conclusions on the distribution, subtypes, and impact of foot/ankle pain. Narrative synthesis of evidence from existing studies suggested preponderance in females, an age-related increase in prevalence in women but not men, that the toes/forefoot were the most common anatomical sites of pain, and that moderate disability in an aspect of daily life was reported by two-thirds of cases. This review provides estimates of the community burden of foot and ankle pain in middle and old age. By outlining the scale of this clinical problem, these findings can be used to inform health care planning and provision.

Cost of illness for patients with arthritis receiving multidisciplinary rehabilitation care

Purpose. To describe healthcare consumption and costs prior to, during, and after multidisciplinary rehabilitation due to arthritis. Methods. 306 patients (age 18-75 years) with arthritis scheduled for multidisciplinary rehabilitation care in 9 rehabilitation centres and 4 rheumatology hospital departments were included and followed for 6 months. Costs were estimated in Euros (€) for the total sample and five clinical subgroups. Results. Healthcare costs ranged from €3,033 to €91,336 and were significantly higher at hospital departments compared to rehabilitation centres: €9,722 (SD 5,406) and €4,250 (SD 1,040). While total costs prior to and after rehabilitation were stable for those receiving rehabilitation at a hospital, there was a significant increase in costs for those being at a rehabilitation centre. Total mean costs were more than doubled when including social costs: from €32,410 (95% CI 20,074-37,017) to €51,491 (95% CI 49,055-61,657). Conclusions. Healthcare and social costs for arthritis rehabilitation were substantial both before and after a rehabilitation stay. It is important to explore methods to reduce the length of rehabilitation stay and production loss connected to rehabilitation of patients with rheumatic disease.

The COPE LBP trial: cognitive patient education for low back pain--a cluster randomized controlled trial in primary care

Background

Non-specific low back pain (LBP) is usually self-limiting within 4-6 weeks. Longstanding pain and disability are not predictable from clinical signs or pathoanatomical findings. Pain cognition and physical performance have been shown to improve patients with chronic LBP following neurophysiological education. The primary aim of this study is to evaluate whether a specific cognitive based education programme for patients with LBP in primary care is more effective than normal care in terms of increased function. The secondary aims of the study are to evaluate whether this intervention also results in earlier return to work, decreased pain, increased patient satisfaction, increased quality-of-life, and cost utility.

Methods/Design

Cluster randomised controlled trial with 20 general practitioners and 20 physiotherapists in primary care as the unit of randomisation. Each practitioner will recruit up to 10 patients, aged 20 to 55 years, with non-specific sub-acute/chronic LBP of more than four weeks but less than 1 year's duration. Practitioners in the intervention arm will provide cognitive patient education intervention in up to four weekly sessions, each lasting 30 minutes. Practitioners in the control arm will provide normal treatment, but have to make four appointments for the patients. Patients, outcome assessors, and study statistician will be blinded to group allocation.

Discussion

We present the rationale and design of an ongoing RCT study that potentially offers an easily implemented treatment strategy for LBP patients in primary care. The results will be available in 2012.

Adult outcomes and lifespan issues for people with childhood-onset physical disability

This paper aimed to discuss functioning, quality of life, (QoL) and lifespan care issues of adolescents and young adults with childhood-onset physical disability from a clinical, scientific, and personal perspective. We present a résumé of results of recently performed studies in rehabilitation-based samples of (young) adults with childhood-onset conditions such as cerebral palsy (CP) and spina bifida (SB), and different models of transition and lifespan care. The studies showed that many young adults with a childhood-onset disability experience health-related problems such as functional deterioration, pain or fatigue, and an inactive lifestyle. A significant number are restricted in participation in work, housing, and intimate relationships. They perceive a lower health-related and global QoL compared with a reference group. In some centres in the UK and the Netherlands specialized outpatient services are available or being developed. In conclusion, transition to adulthood is a critical phase for reaching autonomous participation in adult life. There is an international challenge to incorporate a lifespan perspective in paediatric, transition, and adult health care services for persons with a childhood-onset disability.

Thoracic spine pain in the general population: prevalence, incidence and associated factors in children, adolescents and adults. A systematic review

BACKGROUND

Thoracic spine pain (TSP) is experienced across the lifespan by healthy individuals and is a common presentation in primary healthcare clinical practice. However, the epidemiological characteristics of TSP are not well documented compared to neck and low back pain. A rigorous evaluation of the prevalence, incidence, correlates and risk factors needs to be undertaken in order for epidemiologic data to be meaningfully used to develop evidence-based prevention and treatment recommendations for TSP.

METHODS

A systematic review method was followed to report the evidence describing prevalence, incidence, associated factors and risk factors for TSP among the general population. Nine electronic databases were systematically searched to identify studies that reported either prevalence, incidence, associated factors (cross-sectional study) or risk factors (prospective study) for TSP in healthy children, adolescents or adults. Studies were evaluated for level of evidence and method quality.

RESULTS

Of the 1389 studies identified in the literature, 33 met the inclusion criteria for this systematic review. The mean (SD) quality score (out of 15) for the included studies was 10.5 (2.0). TSP prevalence data ranged from 4.0-72.0% (point), 0.5-51.4% (7-day), 1.4-34.8% (1-month), 4.8-7.0% (3-month), 3.5-34.8% (1-year) and 15.6-19.5% (lifetime). TSP prevalence varied according to the operational definition of TSP. Prevalence for any TSP ranged from 0.5-23.0%, 15.8-34.8%, 15.0-27.5% and 12.0-31.2% for 7-day, 1-month, 1-year and lifetime periods, respectively. TSP associated with backpack use varied from 6.0-72.0% and 22.9-51.4% for point and 7-day periods, respectively. TSP interfering with school or leisure ranged from 3.5-9.7% for 1-year prevalence. Generally, studies reported a higher prevalence for TSP in child and adolescent populations, and particularly for females. The 1 month, 6 month, 1 year and 25 year incidences were 0-0.9%, 10.3%, 3.8-35.3% and 9.8% respectively. TSP was significantly associated with: concurrent musculoskeletal pain; growth and physical; lifestyle and social; backpack; postural; psychological; and environmental factors. Risk factors identified for TSP in adolescents included age (being older) and poorer mental health.

CONCLUSION

TSP is a common condition in the general population. While there is some evidence for biopsychosocial associations it is limited and further prospectively designed research is required to inform prevention and management strategies.

Walking function, pain, and fatigue in adults with cerebral palsy: a 7-year follow-up study

AIM

To compare walking function, pain, and fatigue in adults with cerebral palsy (CP) 7 years after an initial survey.

METHOD

A multidimensional questionnaire was mailed to 226 people with unilateral (hemiplegic) or bilateral (diplegic) spastic CP who had participated in a 1999 survey. People with additional diagnoses were excluded. Special emphasis was placed on participants with deterioration in walking. The questionnaire was the same as in 1999.

RESULTS

One hundred and forty-nine participants (76 males, 73 females; mean age 40y 5mo, SD 10y 7mo, range 24-76y) with a diagnosis of unilateral (n=81) or bilateral (n=68) spastic CP responded. Fifty-two per cent of all participants reported deterioration in walking function since debut of walking, compared with 39% 7 years previously. In participants with bilateral CP, 71% reported deteriorated walking, compared with 37% of participants with unilateral CP. Participants with deteriorated walking function had greater pain frequency, pain intensity, impact of pain on daily activities, and physical fatigue and reduced balance. The number of people reporting overall mobility problems was almost double compared with 7 years previously.

INTERPRETATION

The main finding was an increased prevalence of deteriorated walking, significantly associated with bilateral spastic CP, pain, fatigue, and reduced balance. Rehabilitation programmes addressing these areas are needed.

Obesity and osteoarthritis in knee, hip and/or hand: an epidemiological study in the general population with 10 years follow-up

Background

Obesity is one of the most important risk factors for osteoarthritis (OA) in knee(s). However, the relationship between obesity and OA in hand(s) and hip(s) remains controversial and needs further investigation. The purpose of this study was to investigate the impact of obesity on incident osteoarthritis (OA) in hip, knee, and hand in a general population followed in 10 years.

Methods

A total of 1854 people aged 24–76 years in 1994 participated in a Norwegian study on musculoskeletal pain in both 1994 and 2004. Participants with OA or rheumatoid arthritis in 1994 and those above 74 years in 1994 were excluded, leaving n = 1675 for the analyses. The main outcome measure was OA diagnosis at follow-up based on self-report. Obesity was defined by a body mass index (BMI) of 30 and above.

Results

At 10-years follow-up the incidence rates were 5.8% (CI 4.3–7.3) for hip OA, 7.3% (CI 5.7–9.0) for knee OA, and 5.6% (CI 4.2–7.1) for hand OA. When adjusting for age, gender, work status and leisure time activities, a high BMI (> 30) was significantly associated with knee OA (OR 2.81; 95%CI 1.32–5.96), and a dose-response relationship was found for this association. Obesity was also significantly associated with hand OA (OR 2.59; 1.08–6.19), but not with hip OA (OR 1.11; 0.41–2.97). There was no statistically significant interaction effect between BMI and gender, age or any of the other confounding variables.

Conclusion

A high BMI was significantly associated with knee OA and hand OA, but not with hip OA.

Prevalence of musculoskeletal disorders is systematically higher in women than in men

OBJECTIVES

Many studies report a higher prevalence of musculoskeletal pain in women than in men. This paper presents an overview of sex differences in musculoskeletal pain with specific attention for: different parameters for duration of musculoskeletal pain (ie, 1-y period prevalence, point prevalence, prevalence of chronic pain, and prevalence of persistent chronic pain); and (2) different anatomic pain sites.

METHODS

For the analyses, data from 2 general population-based prospective surveys (Dutch population-based Musculoskeletal Complaints and Consequences Cohort study and Monitoring Project on Risk Factors for Chronic Diseases-study) were used. The study population consisted of persons aged 25 to 64 years living in the Netherlands. Data on self-reported pain complaints were assessed by written questionnaires.

RESULTS

The results of this study showed that prevalence rates of musculoskeletal pain were higher for women than for men in the Dutch general population aged 25 to 64 years on the basis of 2 population-based surveys. For musculoskeletal pain in any location, 39% of men and 45% of women reported chronic complaints. Highest female predominance was found for the hip and wrist/hand, whereas lowest and not statistically significant sex differences were found for the lower back and knee. All duration parameters of musculoskeletal pain showed a female predominance of musculoskeletal pain (1-y period prevalence, point prevalence, prevalence of chronic pain, and prevalence of persistent chronic pain). In those with persistent chronic pain, women tended to report higher severity scores.

DISCUSSION

The present study shows that women have higher prevalence rates of musculoskeletal pain in most anatomic pain sites, no matter the duration of musculoskeletal pain. Future research should focus on explaining these sex differences with the ultimate goal to develop better prevention and management strategies for musculoskeletal pain in both men and women.

Prevalence and characteristics of upper or mid-back pain in Finnish men

STUDY DESIGN

Descriptive epidemiologic study.

OBJECTIVES

To examine the 1-year prevalence, severity, and frequency of mid-back pain in a general population sample of men, with comparisons to neck and low back pain.

SUMMARY OF BACKGROUND DATA

No previous studies reporting the characteristics of mid-back pain in a general population were found.

METHODS

A total of 600 Finnish men 35 to 70 years of age were drawn from a population-based twin sample and interviewed with standardized pain questions.

RESULTS

The 1-year prevalence of mid-back pain was 17.0% (95% confidence interval, 14.3-19.7) compared to 64.0% (95% confidence interval, 60.6-67.5) for neck and 66.8% (95% confidence interval, 63.4-70.3) for low back pain. The frequency of pain over the previous year among those with mid- and low back pain was less than for neck pain. The mean severity of the worst pain episode was highest for low back pain followed by mid-back and neck pain, which were similar. Associated disability tended to be less frequent from mid-back pain (23.5% vs. 30.3%-41.1%). Odds ratios for neck and low back pain when mid-back pain was reported were 2.32 and 2.86, respectively.

CONCLUSION

The prevalence of mid-back pain was approximately one fourth that of neck and low back pain and was somewhat less likely to be disabling. In cases of mid-back pain, spinal comorbidity was nearly always reported.

Self-reported work-related health problems from the Oslo Health Study

BACKGROUND

Lack of knowledge about the occurrence of work-related health problems in the general population makes it difficult to estimate the potential for their prevention in the workplace.

AIMS

To examine the prevalence of self-reported work-related health problems among adult citizens of Oslo, Norway.

METHODS

The study was part of the Oslo Health Study 2000-2001, in which all individuals in certain age cohorts were invited to a comprehensive health screening. All 30-, 40- and 45-year old subjects who attended the screening were asked if they had experienced any of 11 common health problems in the past month, and whether they considered these to be work-related. Of the 26,074 invitees in these age cohorts, 8,594 (33%) answered the questionnaire.

RESULTS

Nearly 60% of subjects reported one or more work-related health problems, most commonly reported were pain in the neck/shoulders (38%) and low back pain (23%). Neck/shoulder pain was most frequently attributed to working conditions, by 74% of subjects with this problem; followed by arm pain (72%), fatigue (51%) and low back pain (50%). Work-related fractions for eczema and asthma symptoms were 23 and 18%, respectively. There were marked gender differences, but small age differences.

CONCLUSIONS

A substantial proportion of common health problems in the Oslo population were attributed to working conditions. This implies a large preventive potential and call for increased preventive efforts targeted at known risk factors in the workplace.

Explaining sex differences in chronic musculoskeletal pain in a general population

Many studies report a female predominance in the prevalence of chronic musculoskeletal pain (CMP) but the mechanisms explaining these sex differences are poorly understood. Data from a random postal questionnaire survey in the Dutch general population were used to examine whether sex differences in the prevalences of CMP are due to sex differences in the distribution of known potential risk factors for CMP (exposure model) and/or to the different importance of risk factors for CMP (i.e. show different strength of association) in men and women (vulnerability model). In the present analyses, 909 men and 1178 women aged 25-65 were included. CMP was defined as pain lasting longer than 3 months and was assessed for 10 anatomical locations (neck, shoulder, higher back, elbow, wrist/hand, lower back, hip, knee, ankle, foot). Sex differences in CMP could not be explained by a different distribution of age, educational level, smoking status, overweight, physical activity, and pain catastrophizing. Having no paid job was associated with CMP, explaining part of the sex differences, but its role seems complex. Risk factors with a sex-specific association were: overweight (all pain locations) and older age (lower extremities)--both having only an effect among women--and pain catastrophizing (upper extremities), which was stronger associated with CMP among men than among women. In conclusion, sex differences in prevalence of CMP may partly be explained by sex differences in vulnerability to risk factors for CMP. Future research towards sex-specific identification of risk factors for CMP is warranted. Eventually this may lead to sex-specific prevention and management of CMP.

Musculo-skeletal pain among 40- and 45-year olds in Oslo: differences between two socioeconomically contrasting areas, and their possible explanations

BACKGROUND: The objective of the study was to compare the prevalence and severity of musculo-skeletal pain between two socioeconomically contrasting areas in Oslo, Norway, and to explore possible explanatory factors. METHODS: Questionnaire survey, carried out as part of The Oslo Health Study in 2000-2001. Data from 821 persons (40 and 45 year old) living in a less affluent inner city area (called east) were compared with 854 persons living in an affluent area of the city (called west). Bivariate comparisons (chi square test) and multiple regression analyses were performed to investigate differences between the samples. RESULTS: 61 % in east and 56 % in west (p < 0.05) reported pain/stiffness in muscles/joints during the last four weeks. 30 % in east versus 19 % in west (p < 0.001) reported extensive pain. The between area difference in extensive pain was partially explained by physical inactivity, mental health problems and being of non-Western origin. CONCLUSION: Musculo-skeletal pain is reported by 55-60 % of middle aged persons in Oslo during a four week period, and must be considered a normal phenomenon. Poor social conditions, inactivity, mental health problems and being an immigrant imply increased risk of more severe symptoms with a concomitant demand of health care.

It is hard work behaving as a credible patient: encounters between women with chronic pain and their doctors

In various studies during the last decade, women with medically unexplained disorders have reported negative experiences during medical encounters. Accounts of being met with scepticism and lack of comprehension, feeling rejected, ignored, and being belittled, blamed for their condition and assigned psychological explanation models are common. Women patients exerted themselves to attract the doctor's medical attention and interest, and were anxious to be considered as whiners or complainers. Here, we explore the nature of "work" done by the patients in order to be believed, understood, and taken seriously when consulting the doctor. A qualitative study was conducted with in-depth interviews including a purposeful sampling of 10 women of varying ages and backgrounds with chronic muscular pain. The main outcome measures were descriptions reflecting the patients' activities or efforts invested in being perceived as a credible patient. We focused on the gendered dimensions of the experiences. The women patients' accounts indicated hard work to make the symptoms socially visible, real, and physical when consulting a doctor. Their efforts reflect a subtle balance not to appear too strong or too weak, too healthy or too sick, or too smart or too disarranged. Attempting to fit in with normative, biomedical expectations of correctness, they tested strategies such as appropriate assertiveness, surrendering, and appearance. The most important activities or efforts varied. However, the informants were not only struggling for their credibility. Their stories illustrated a struggle for the maintenance of self-esteem or dignity as patients and as women. The material was interpreted within a feminist frame of reference, emphasising the relationship between dignity and shame, power and disempowerment for women patients' with medically unexplained disorders.

Low back pain as a predictor of long-term work disability

AIM

To investigate low back pain (LBP), with and without other musculoskeletal pains, as a predictor of long-term work disability.

METHOD

A four-year prospective study was conducted. All inhabitants in the municipality of Ullensaker, Norway, born in 1928-30, 1938-40, 1948-50, 1958-60 and 1968-70, received a mailed questionnaire in 1990 and 1994. The present study comprised the 1.788 responders who were working in 1990. Of these, 1426 (80%) returned the questionnaire four years later. The main outcome measure was long-term work disability (>eight weeks) in 1994.

RESULTS

LBP in 1990 predicted long-term work disability in 1994 (odds ratio (OR) = 1.95, 95% confidence interval (CI) = 1.39-2.74). Localized LBP however, did not predict long-term work disability, while LBP accompanied by widespread pain did (OR = 3.52, 95% CI = 1.09-11.37), also after adjustments for demographic, lifestyle, and work-related factors. Other predictors of long-term work disability were high age, sick leave last year, heavy lifting in the job, poor sleep quality and smoking.

CONCLUSION

LBP in persons with widespread musculoskeletal pain predicted long-term work disability, while localized LBP did not.

Encountering the continuing challenges for women with chronic pain: recovery through recognition

This work is based on experiences from a group treatment for women with chronic musculoskeletal pain. The authors explored the nature and consequences of the reported benefits from being met with recognition in the groups, focusing the potential usefulness in everyday life. In-depth interviews of six participants of various age and backgrounds were conducted. The women's answers reflected how recognition had enhanced strength, confidence, and awareness expressed as increased bodily, emotional, and social competence. This competence provided tools to handle their pain and illness. Achieving the sense of a better life with chronic pain represents an important recovery process. Because of the normative and gendered way the term "coping(ability)" has been used, the authors introduce recovery competence as a more fruitful concept.

Regional musculoskeletal conditions: shoulder pain

About half the population has at least one episode of shoulder pain yearly. History and clinical examination are cornerstones in the evaluation of the patient. Shoulder pain at the work place is associated with job strain: lack of control and work with elevated arms and hand tools. Clinical skills and knowledge about red and yellow flags and biomechanics are essential to perform a systematic and reliable evaluation. The diagnostic validity of clinical tests for rotator cuff tear, impingement syndrome and superior labral tears is equal or better than ultrasound and magnetic resonance imaging. Non-steroidal anti-inflammatory drugs and cortico-steroidal injections have documented short-term pain relief. Additionally, the physician should attempt to give the patient simple advice and reinforce active coping strategies. One randomized study suggests that a proper physiotherapy regimen and surgery are equally effective for the impingement syndrome. Further research should address the cost-effectiveness of diagnostic methods and treatments.

The epidemiology of soft tissue rheumatism

Soft tissue rheumatism forms a broad spectrum of health problems, most of them poorly defined according to diagnostic criteria and case definitions. In this chapter the most prevalent conditions, low back pain, neck pain, shoulder pain, arm/wrist/hand conditions and widespread pain, are discussed. A better term for referring to these health problems is regional and widespread pain disorders. The prevalence and the impact on health care and society of these conditions is high. Many physical, psychosocial and work-related factors play a role in aetiology and prognosis. A good prevention policy does not exist for most conditions due to the lack of knowledge on risk factors, risk groups and trends. To improve the epidemiological research on regional and widespread pain disorders, research should focus on clear and relevant definitions of cases or pain subgroups and on specific risk factors.

Agency orientation and chronic musculoskeletal pain: effects of a group learning program based on the personal construct theory

OBJECTIVE

This study evaluated the effects of a group learning program on patients with chronic musculoskeletal pain and high absenteeism and investigates what characterizes those patients who may benefit from such a program. The learning program was based on personal construct theory. The theory included the following: (1) participation in an educational program is related to a favorable outcome across the outcome measures (pain, pain coping, management of daily life, absenteeism, and use of health care), (2) patients with high agency orientation (i.e., inner-directed) cope with their pain and manage daily life in a better manner than do patients with low agency orientation (i.e., outer-directed), and (3) patients with high personal control, measured in terms of agency orientation, in terms of health locus of control, or in both terms, will benefit more from the educational program than will patients with low personal control.

DESIGN

The study was a randomized controlled study.

PATIENTS

One hundred and sixteen patients with chronic musculoskeletal pain and high absenteeism answered a questionnaire before and after the intervention program. The intervention group (n = 61) consisted of nine subgroups geographically spread through the eastern part of Norway and met for four hours every 2 weeks from February 1997 to October 1997. A total of 12 meetings were held.

RESULTS

The intervention group reported a significantly higher score for the variable "management of everyday life" (p <0.005) and for the variable "health care consumption" (p <0.001) than did the control group. Patients with high agency orientation benefited more from the program with regard to pain reduction and improved pain coping than did those patients with low agency orientation (p <0.05). Patients with high agency orientation also reported less absenteeism than did those patients with low agency orientation (p <0.05).

Job characteristics as predictors of neck pain. A 4-year prospective study

Data from a community-based 4-year prospective study were used to investigate job characteristics as predictors of neck pain. Of 1791 working responders who completed a questionnaire in 1990, 1429 (79.8%) returned a second questionnaire 4 years later (1994). In responders without neck pain during the previous 12 months in 1990, the "little influence on own work situation" factor predicted neck pain during the previous 12 months (odds ratio = 2.21; 95% confidence interval, 1.18 to 4.14) and previous 7 days in 1994 (OR = 2.85; 95% confidence interval, 1.21 to 6.73) after adjustment for a series of potential confounders. In responders with neck pain in 1990, the little influence on own work situation factor was associated with persistent neck pain 4 years later. The study indicates that having little influence on one's own work situation is a predictor of neck pain.

Physical leisure activity level and physical fitness among women with fibromyalgia

To determine selfreported physical leisure activity level and physical fitness in women with fibromyalgia we sent questionnaires to the female members of a local fibromyalgia association and the same questionnaire to the women in a population based cohort study. The fibromyalgia patients had higher physical leisure activity level, but lower physical fitness than the women in the population survey. The difference in physical leisure activity persisted even after controlling for a series of possible confounders, including employment status and work load in a logistic regression analysis.

Musculoskeletal pain and smoking in Norway

OBJECTIVE

To examine the association between musculoskeletal pain and smoking.

DESIGN

Cross sectional, national interview survey.

SETTING

All individuals in a representative sample of households in Norway in 1985.

SUBJECTS

A total of 6681 persons aged 16 to 66 years old. people in institutions were not included.

OUTCOME MEASURES

Gender specific and age specific prevalence rates for pain in the cervical region/upper limbs, back, and lower limbs.

RESULTS

Current smoking was independently associated with musculoskeletal pain (odds ratio (OR) 1.69; 95% confidence interval (95% CI) 1.45, 1.97) after adjustment for gender, age, comorbidity, mental distress, lifestyle factors, and occupation related factors. The association was of similar strength regarding cervical/upper limb pain (OR 1.87; CI 1.56, 2.25) and back pain (OR 1.84; CI 1.50, 2.25) but weaker in respect of lower limb pain (OR 1.37; CI 1.10, 1.71). Musculoskeletal pain was often present in more than one site.

CONCLUSION

Smoking was significantly associated with musculoskeletal pain after adjustment for other relevant factors.
