The association between diabetes mellitus, glucose, and chronic musculoskeletal complaints. Results from the Nord-Trøndelag Health Study

Association of musculoskeletal pain with the achievement of treatment targets for type 2 diabetes among primary care patients

AIMS

To assess the association of diagnosed musculoskeletal (MS) pain (low back, neck, shoulder, and knee pain; and the number of pain sites) with the achievement of targets for glycosylated haemoglobin A1c (HbA1c), low-density-lipoprotein cholesterol (LDL), and systolic blood pressure (SBP) among primary care patients with type 2 diabetes (T2D).

METHODS

The cross-sectional study population consisted of 3478 patients with a registry-based T2D diagnosis and available registry-based data on MS pain diagnoses, covariates, and outcomes between 2016 and 2019. Logistic regression analysis was used to evaluate the study aims.

RESULTS

Overall, 22% had at least one of the four types of MS pain, and 73%, 57%, and 51% achieved the treatment targets of HbA1c, LDL, and SBP, respectively. T2D patients with or without MS pain did not differ in their achievement of T2D treatment goals. Of pain locations, low back pain was associated with higher rates of achievement of the LDL target (OR 1.29, 95% CI 1.01-1.65), but the association was attenuated in the adjusted model.

CONCLUSIONS

MS pain was relatively prevalent among primary care patients with T2D, but did not influence the achievement of T2D treatment goals.

The association between diabetes mellitus and functionality in knee osteoarthritis: a cross-sectional study

Objective: The aim of this study was to determine the roles of diabetes mellitus (DM) on quality of life, function of knee, and muscle strength in patients with knee osteoarthritis (OA). Material and Method: This single-center, case-control study prospectively enrolled outpatients with knee OA visiting a physical therapy and rehabilitation clinic. The patients were grouped according to the presence of DM diagnosis. Demographic data, disease duration, and medical treatments of patients were recorded. Clinical parameters, radiographic grading (Kellgren-Lawrence grades), functional scales of the knee and quality of life were evaluated. Results: The study included 82 participants [age: 61.3±6.7 years; female: 76.8%]. The mean Western Ontario and McMaster Universities Osteoarthritis Index of OA patients with (n=37) and without DM (n=45) were 45.79±18.04 vs. 65.94±16.23, respectively (p=0.003). The Hb A1c levels showed a negative correlation with Knee Injury and Osteoarthritis Outcome Score components (pain, quality of life, sports, daily activities, symptom duration) (p

Management of the Cavity After Removal of Giant Cell Tumor of the Bone

Purpose: To find out the most appropriate management scheme through the analysis and comparison of different inactivation methods and filling materials. Method: A systematic literature search was performed using the terms, anhydrous ethanol, phenol, hypertonic saline, cryotherapy, thermal therapy, bone reconstruction, GCTB, and etc., Selected articles were studied and summarized. The mechanism, clinical effects, and influence on bone repair of various methods are presented. Recent developments and perspectives are also demonstrated. Recent Findings: Compared to curettage alone, management of the residual cavity can effectively reduce the recurrence of giant cell tumours of bone. It is a complex and multidisciplinary process that includes three steps: local control, cavity filling, and osteogenic induction. In terms of local control, High-speed burring can enlarge the area of curettage but may cause the spread and planting of tumour tissues. Among the inactivation methods, Anhydrous ethanol, and hyperthermia therapy are relatively safe and efficient. The combination of the two may achieve a better inactivation effect. When inactivating the cavity, we need to adjust the approach according to the invasion of the tumour. Filling materials and bone repair should also be considered in management.

Prevalence of Upper Extremity Musculoskeletal Disorders in Patients with Type 2 Diabetes in General Practice

Background: One of the lesser recognized complications of diabetes mellitus are musculoskeletal (MSK) complications of the upper and lower extremity. No prevalence studies have been conducted in general practice. Thus, the aim of this study was to investigate the prevalence of upper extremity MSK disorders in patients with type 2 diabetes (T2DM) in the Netherlands. Methods: We conducted a cross-sectional study with two different approaches, namely a representative Dutch primary care medical database study and a questionnaire study among patients with T2DM. Results: In the database study, 2669 patients with T2DM and 2669 non-diabetes patients were included. MSK disorders were observed in 16.3% of patients with T2DM compared to 11.2% of non-diabetes patients (p < 0.001, OR 1.53, 95% CI 1.31, 1.80). In the questionnaire study, 200 patients with T2DM were included who reported a lifetime prevalence of painful upper extremity body sites for at least four weeks of 67.3%. Conclusion: We found that upper extremity MSK disorders have a high prevalence in Dutch patients with T2DM presenting in general practice. The prevalence ranges from 16% based on GP registered disorders and complaints to 67% based on self-reported diagnosis and pain. Early detection and treatment of these disorders may play a role in preventing the development of chronic MSK disorders.

Prevalence and Correlates of Musculoskeletal Pain in Adults with Type 2 Diabetes in Populations with Low-Risk of Obesity: A Cross-Sectional Study

BACKGROUND

There are few data concerning the prevalence and predictors of musculoskeletal pain among adults with type 2 diabetes in population with low-risk of obesity. Our objective was to describe the point prevalence and factors associated with increased risk of musculoskeletal pain in this population.

METHODS

A cross-sectional data of 200 adults with type 2 diabetes, aged ≥ 18 years who were attending two tertiary hospitals were examined. Musculoskeletal pain and physical activity were collected with Nordic Musculoskeletal Questionnaire (NMQ) and International Physical Activity Questionnaire (IPAQ-SF) respectively. We used logistic regression to examine the risks associated with musculoskeletal pain.

RESULTS

The point prevalence of musculoskeletal pain was 72.7% and similar between men (72.3%) and women (73.1%). In the last 7days, advancing age (odds ratio=1.09;95%CI:1.02-1.16) and comorbidity (odds ratio=3.0;95%CI:1.07-8.39) were risk factors associated with musculoskeletal pain. In the last 12 months, only comorbidity (odds ratio=5.57;95%CI:1.62-19.17) was a risk factor for increasing musculoskeletal pain. However, a unit increase in physical activity level (odds ratio=0.06;95%CI:0.008-0.51) was associated with decreased odds of musculoskeletal pain.

CONCLUSIONS

The prevalence of musculoskeletal pain was high and physical activity was associated with a decreased risk thereof. A further research should be evaluated on the influence of physical activity on musculoskeletal pain.

Musculoskeletal Conditions in Patients With Diabetes: A Narrative Review

Diabetes mellitus (DM) is a multisystem disease that affects millions of people worldwide. The vascular and cardiac effects of DM have been well-studied, but little is known about the prevalence of musculoskeletal (MSK) conditions in patients with DM. This review provides an in-depth analysis of a cross-sectional study investigating the presence of several common MSK disorders in patients with DM. This review also analyzes current literature to update health care professionals about the MSK conditions associated with DM.

Not a Painless Condition: Rheumatological and Musculoskeletal Symptoms in Type 2 Diabetes, and the Implications for Exercise Participation

OBJECTIVES

People with type 2 diabetes (T2D) are more likely to develop a range of rheumatological and musculoskeletal symptoms (RMS), and experience both chronic and widespread pain, compared with the general population. However, these symptoms are not commonly acknowledged by researchers, which hampers our understanding of the impact on this population. Since exercise is a key lifestyle management strategy for T2D and participation levels are typically low, understanding the potential impact of RMS on exercise participation is critical. The aim of this review is to summarise the literature regarding the prevalence and pathophysiology of RMS in T2D, the evidence for the benefits and risks associated with exercise on RMS, and the currently available tools for the reporting of RMS in both research studies and community settings.

METHODS

A narrative review.

RESULTS

There are numerous exercise trials in T2D, but few have sufficiently reported pain-related adverse events and even fewer have investigated the effects of exercise on RMS and chronic pain.

DISCUSSION

Recommendations for future research are provided.

Joint pain within adult middle-aged women, attending a community clinic in a peri-urban area in South Africa: a cross-sectional survey

BACKGROUND

This study aimed to investigate the prevalence of joint pain in women between the ages of 40 and 64 years who attended a community clinic in the Free State to provide micro-information for health care planners.

METHODS

A sample of convenience was utilized in the cross-sectional survey. Health care workers were recruited to conduct the survey. Outcome measures included the Community-Oriented-Programme-For-The-Control-Of-Rheumatic-Disease questionnaire and European Quality of Life - 5 Dimensions health related quality of life measure. Descriptive statistics were calculated for categorical data and non-parametric tests for ordinal data. Quality Adjusted Life Years lost were based on the preference weights generated by the European Quality of Life - 5 Dimensions.

RESULTS

One thousand three hundred seventy-six participants were enrolled. The prevalence of joint pain experienced in either the short or the long term was 62.1% (CI 59.5-64.6%). The total number of Quality Adjusted Life Years lost in this sample was 41.4, that is a rate of 3008.7 (CI 2740-3310) per 100,000.

CONCLUSION

Epidemiological transition seems to be rapidly taking place in South Africa and the prevalence of joint pain is considerable. Primary health care systems should develop a cost-effective approach to manage and identify joint pain and improve the health-related quality of life of those living with this. Implications for Rehabilitation Prevalence of joint pain is considerable. Consume large amounts of health and social resources. A protocol for routine screening should be developed in community clinics. Cost-effective approach to manage joint pain should be identified to improve healthrelated quality of life of individuals living with joint pain.

Physical activity and disability measures in chronic non-specific low back pain: a study of responsiveness

Objectives:

To compare the responsiveness of disability measures with physical activity measures in patients with chronic low back pain (CLBP) undergoing a course of physical therapy treatment.

Design:

This is a prospective cohort study with two-month follow-up.

Subjects:

A total of 106 patients presenting with non-specific CLBP of more than three months duration were recruited.

Main measures:

Disability measures investigated were Quebec Back Pain Disability Scale and Roland Morris Disability Questionnaire. Physical activity measures analyzed include the Baecke Habitual Physical Activity Questionnaire and objective measures derived from an accelerometer (i.e. total time spent in moderate-to-vigorous and light physical activity, number of steps and counts per minute). Disability and physical activity measures were collected at the baseline and after eight weeks of treatment. For the responsiveness analyses, effect size (ES) and standardized response mean (SRM) were calculated. Correlations between the change in disability and physical activity measures were calculated.

Results:

Responsiveness for disability measures was considered to be large with ESs ranging from −1.03 to −1.45 and SRMs ranging from −0.99 to −1.34, whereas all physical activity measures showed values lower than 0.20. Changes in disability measures did not correlate with changes in physical activity measures (correlation coefficients ranged from −0.10 to 0.09).

Conclusion:

Disability measures were responsive after a course of physical therapy treatment in patients with CLBP. The lack of responsiveness in the physical activity measures might be due to the inability of these measures to detect change over time or the use of an intervention not designed to increase physical activity levels.

Effect of Rebound Exercises and Circuit Training on Complications Associated with Type 2 Diabetes: Protocol for a Randomized Controlled Trial

BACKGROUND

The incidence of type 2 diabetes mellitus, a chronic lifestyle disease, and its complications are on the rise. Exercise has been documented as being effective in the management of musculoskeletal pain, depression, and reduction of hyperglycemia in diabetic patients. However, there is no consensus regarding the types of exercise that reduce musculoskeletal pain and depression and improve quality of life as well as respiratory function among individuals with type 2 diabetes.

OBJECTIVE

The objective of this study is to determine the effects of rebound and circuit training on musculoskeletal pain, blood glucose level, cholesterol level, quality of life, depression, and respiratory parameters in patients with type 2 diabetes mellitus.

METHODS

A total of 70 participants are expected to be recruited in this single blind randomized controlled trial. Computer-generated random numbers will be used to randomize the participants into 3 groups, namely, the rebound exercise group, the circuit exercise group, and the control group. Measurements will be taken at baseline and at the end of the 8 weeks of the study. Participants' musculoskeletal pain will be assessed using the visual analog scale, quality of life will be assessed using the SF 12 Health Survey Questionnaire, depression using the Beck Depression Inventory, respiratory parameters using the spirometer, and biochemical parameters such as glucose level and cholesterol level using the glucometer. Data will be analyzed using descriptive statistics and inferential statistics of multivariate analysis of variance between the groups and paired t test within the group. Alpha will be set at .05.

RESULTS

The results of this study will identify the effectiveness of rebound exercise and circuit training, compared with the control, in the management of type 2 diabetes mellitus and on quality of life, musculoskeletal pain, depression, glycemic control, cholesterol level, as well as improvement in respiratory function.

CONCLUSIONS

Though different additional strategies such as exercise and dietary and lifestyle modifications exist for the control of type 2 diabetes, they are mostly applied for the control of glucose level. No strategies have been identified for the control of complications associated with diabetes such as musculoskeletal pain, depression, and reduction in quality of life.

Cardiovascular risk reduction as a population strategy for preventing pain?

In this issue of the Scandinavian Journal of Pain, Pico-Espinosa and co-workers [1] report on the role of diabetes mellitus (DM) and hyperlipidaemia (HL) as risk factors for frequent pain in the back, neck and/or shoulders/arms (BNSP). Their study was based on a large population-based cohort with a four-year follow-up. They concluded that DM and HL may play a role in the aetiology of frequent BNSP, but this role may be different in men and women.

Chronic disruptive pain in emerging adults with and without chronic health conditions and the moderating role of psychiatric disorders: Evidence from a population-based cross-sectional survey in Canada

BACKGROUND AND AIMS

There has been a growth in the proportion of emerging adults vulnerable to pain-related sequelae of chronic health conditions (CHCs). Given the paucity of research during this important developmental period, this study investigated the association between CHCs and chronic disruptive pain among emerging adults and the extent to which psychiatric disorders moderate this association.

METHODS

Data come from the 2012 Canadian Community Health Survey - Mental Health (CCHS-MH). This cross-sectional survey included 5987 participants that were 15-30 years of age and self-reported their CHCs (n=2460, 41%) and the extent to which pain impacted daily functioning using items from the Health Utilities Index Mark 3 (HUI 3). Group comparisons between respondents with CHCs and healthy controls were made using chi-square tests. Odds ratios (OR) and 95% confidence intervals (CI) were computed from ordinal logistic regression models adjusting for sociodemographic covariates. Product-term interactions between CHCs and psychiatric disorders were included in the models to explore moderating effects. All analyses were weighted to maintain representativeness of the study sample to the Canadian population.

RESULTS

The mean age of participants was 23.5 (SE 0.1) years and 48% were female. Compared to healthy controls, a greater proportion of participants with CHCs reported having chronic pain (20.3% vs. 4.5%, p<0.001). Among those with chronic pain, respondents with CHCs reported a greater number of activities prevented because of chronic disruptive pain (χ²=222.28, p<0.001). Similarly, in logistic regression models, participants with CHCs had greater odds of reporting chronic disruptive pain (OR=4.94, 95% CI=4.08-5.99). Alcohol (β=-0.66; p=0.025) and drug abuse/dependence disorders (β=-1.24; p=0.012) were found to moderate the association between CHCs and chronic disruptive pain. Specifically, the probability of chronic disruptive pain was higher for emerging adults without CHCs and with alcohol or drug disorders; however, among participants with CHCs, probability was higher for those without these disorders.

CONCLUSIONS

There is a robust association between CHCs and chronic disruptive pain. The moderating effects suggest that alcohol or drug disorders are especially harmful for emerging adults without CHCs and contribute to higher levels of chronic disruptive pain; however, among those with CHCs, alcohol and illicit drugs may be used as a numbing agent to blunt chronic disruptive pain.

IMPLICATIONS

Findings from this study have implications for the integration and coordination of services to design strategies aimed at managing chronic disruptive pain and preventing pain-related disabilities later in life. Within the health system, healthcare providers should engage in dialogues about mental health and substance use regularly with emerging adults, be proactive in screening for psychiatric disorders, and continue to monitor the impact of pain on daily functioning. Given the age range of emerging adults, there is tremendous opportunity for clinicians to work cooperatively with colleagues in the education system to support emerging adults with and without CHCs. Overall, clinicians, researchers, educators, and those in social services should continue to be mindful of the complex interrelationships between physical and mental health and chronic disruptive pain and work cooperatively to optimize health outcomes and prevent pain-related disabilities among emerging adults.

Physical Activity Interventions for Increasing Objectively Measured Physical Activity Levels in Patients With Chronic Musculoskeletal Pain: A Systematic Review

OBJECTIVE

To investigate whether physical activity interventions increase objectively measured physical activity levels of patients with chronic musculoskeletal pain (e.g., osteoarthritis, low back pain) compared to no/minimal intervention.

METHODS

We performed a systematic review with meta-analysis searching the Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, SportDiscus, and Physiotherapy Evidence Database (PEDro) databases, and the main clinical trials registries. Quasirandomized or randomized controlled trials investigating the effect of physical activity interventions on objectively measured physical activity levels (e.g., using accelerometers or pedometers) of patients with chronic musculoskeletal pain compared with no/minimal intervention were considered eligible. Analyses were conducted separately for short-term (≤3 months), intermediate (>3 months and <12 months), and long-term (≥12 months) followups. Pooled effects were calculated using the standardized mean difference (SMD), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used in summary conclusions.

RESULTS

Eight published trials and 6 registered trials were included. For the short-term followup, pooling of 6 trials showed no significant effect (SMD 0.34, 95% confidence interval -0.09, 0.77) between a physical activity intervention and no/minimal intervention. Similarly nonsignificant results were found for the intermediate and long-term followups. The overall evidence according to the GRADE approach was classified as low quality.

CONCLUSION

Our findings suggest that physical activity-based interventions may lead to little or no difference in objectively measured physical activity levels of patients with chronic musculoskeletal pain compared with no/minimal interventions. Given the number of registered trials, the pooled effect found in this review is likely to change once the results of these trials become available.

Musculoskeletal pain in people with and without type 2 diabetes in Taiwan: a population-based, retrospective cohort study

Background

Musculoskeletal pain in people with type 2 diabetes is a common issue even to this day. The study aimed to explore the 10-year cumulative incidence of musculoskeletal pain, the mean number of doctor visits for musculoskeletal pain, and the mean number of doctor visits for musculoskeletal pain by location in people with type 2 diabetes, compared with respective values for people without diabetes.

Methods

The study utilized a population-based retrospective cohort study design. The subjects were randomly obtained from the Taiwan National Health Insurance Research Database. The diabetic group included 6586 people with type 2 diabetes aged 18–50 years, while the non-diabetic group consisted of 32,930 age- and sex-matched people. Based on the medical records of individuals with musculoskeletal pain in the two groups from 2001 to 2010, the 10-year cumulative incidence of musculoskeletal pain, the mean number of doctor visits for musculoskeletal pain, and the mean number of doctor visits for musculoskeletal pain by location were calculated and compared, with the aim of identifying differences between the two groups.

Results

Showed that people in the diabetic group had a higher 10-year cumulative incidence of and a higher mean number of doctor visits for musculoskeletal pain than the non-diabetic group (p < 0.05). The relative risk (RR) of the 10-year cumulative incidence of musculoskeletal pain in the two groups was the highest (RR = 1.39) for people between 30 and 39 years of age. The mean number of doctor visits for musculoskeletal pain by location was significantly different between the two groups. However, the mean number of doctor visits for limb pain registered the largest difference between the two groups.

Conclusion

People with type 2 diabetes aged 18–50 years had a higher 10-year cumulative incidence of and a higher mean number of doctor visits for musculoskeletal pain than the non-diabetic group. Musculoskeletal pain might directly or indirectly interfere with or decrease the physical activity levels of people with diabetes. Therefore, it is important to detect and treat musculoskeletal pain early in order to promote physical activity and optimize blood sugar control.

Musculoskeletal manifestations in diabetic versus prediabetic patients

AIM

This study was carried out to evaluate the prevalence of musculoskeletal manifestations in a sample of patients with diabetes mellitus (DM) and those with prediabetes and compare the findings between the two groups.

METHODS

One hundred and eighty-eight patients with DM and 125 prediabetic subjects were randomly enrolled in this cross-sectional study. Demographic data and past history were recorded. Musculoskeletal physical examinations were done by a single rheumatologist. Regression analyses were employed to assess the crude and adjusted effects of determinants on DM musculoskeletal manifestations (DMMMs).

RESULTS

Female/male ratio was not significantly different between diabetic and prediabetic patients (4.4 vs. 4.7, respectively, P = 0.9). However, diabetic patients were significantly older than the prediabetic ones (56.6 vs. 52 years, respectively, P = 0.0001); 83.5% of diabetic patients and 52.8% of prediabetic ones had at least one musculoskeletal manifestation (P = 0.0001). The prevalence of knee osteoarthritis and shoulder involvement were almost two times more common (P = 0.0001 and P = 0.015) in diabetic patients than in prediabetic ones (73.4% vs. 38% and 21.2% vs. 9.5%, respectively). Prevalence of carpal tunnel syndrome (CTS) was 48% and 36.5% in patients with diabetes and prediabetes, respectively (P = 0.053). Multivariate backward regression analysis showed age, sex, BMI (body mass index) and DM as the significant determinants in development of musculoskeletal manifestations in all subjects. Age and BMI were the only significant factors associated with musculoskeletal manifestations in both diabetic and prediabetic patients.

CONCLUSION

Diabetic and prediabetic patients may show high prevalence of musculoskeletal manifestations. In non-diabetic patients diagnosed with CTS, prediabetes might be ruled out.

Pain reports in children and adolescents with type 1 diabetes mellitus

The purpose of this study is to examine prevalence rates of pain reports in youth with type 1 diabetes mellitus (T1DM) and potential predictors of pain. Pain is a common and debilitating symptom of diabetic polyneuropathies. There is currently little research regarding pain in youth with T1DM. It was predicted that self-care and general health factors would predict pain as suggested by the general pain literature. Participants (N = 269) ranged in age from 13 to 17 years; youth had a mean time since diagnosis of 5.8 years. Data collected included diabetes self-management variables, ratings of the patient's current functioning and pain intensity ('current'), and information collected about experiences that occurred in the time preceding each appointment ('interim'). About half of the youth (n = 121, 49.0%) reported any interim pain across both appointments. Female adolescents and those individuals who were physically active and/or utilized health-care system more acutely were more likely to report interim central nervous system pain. Improved diabetes self-management and increased level of physical activity may reduce experiences of pain and increase the quality of life of youth with T1DM. Regular monitoring of both current and interim pain experiences of youth with T1DM is recommended.

Prognostic factors of prolonged disability in patients with chronic low back pain and lumbar degeneration in primary care: a cohort study

STUDY DESIGN

A cohort study with 1-year follow-up.

OBJECTIVE

To identify prognostic factors in patients with chronic nonspecific low back pain (LBP).

SUMMARY OF BACKGROUND DATA

The factors (e.g., sociodemographical, low back-related, radiological, and biological) associated with persistent pain and disability for patients with chronic nonspecific LBP are uncertain. Furthermore, sparse information exists about the relationship between biological factors like impaired fasting glucose tolerance and chronic nonspecific LBP.

METHODS

The participants consisted of 250 patients with nonspecific LBP of more than 6 months duration and degenerative lumbar osteoarthritis. The patients were originally recruited for a randomized controlled trial from the clinics of general practitioners, physiotherapists, and chiropractors. Potential predictors were evaluated at baseline. The outcome was absolute level of pain-related disability (Roland-Morris Disability Questionnaire [RMDQ]) at 1 year. The association between potential prognostic factors and the outcome was analyzed with multivariate linear backward regression.

RESULTS

At baseline and 1 year, the RMDQ scores were 9.5 and 5.1 points, respectively. Mean (SD) baseline values for body mass index (BMI), EuroQol (EQ)-index, EQ-visual analogue scale were 25.4 (4.3), 0.60 (0.3), and 61.2 (20.8), respectively. Higher pain-related disability levels (1-year RMDQ score) were associated with 6.1 mmol/L or more fasting glucose level at baseline (β, 3.7; 95% confidence interval [CI], 1.2-6.1; P = 0.00), baseline pain-related disability (β 0.2; 95% CI, 0.1-0.4; P = 0.00), BMI (β, 0.2; 95% CI, 0.1-0.3; P < 0.03), EQ-index (β, -4.5; 95% CI, 6.9 to 2.1; P = 0.00), and EQ-visual analogue scale (β, 0.3; 95% CI, -0.6 to -0.0; P = 0.03). However, a limited number of patients had 6.1 mmol/L or more of fasting glucose level at baseline (13/250 patients). The imaging findings, modic changes, and high intensity zones had no predictive ability.

CONCLUSION

Increased pain-related disability at 1 year was seen in patients with impaired fasting glucose tolerance, greater pain-related disability, higher BMI, and lower quality of life at baseline.

Increasing prevalence of chronic musculoskeletal complaints. A large 11-year follow-up in the general population (HUNT 2 and 3)

OBJECTIVES

To assess the prevalence of chronic musculoskeletal complaints (MSCs) in a large adult population, and to determine any changes in prevalence during an 11-year period.

METHODS

This study involved two large cross-sectional surveys (Helseundersøkelsen i Nord-Trøndelag [HUNT] 2 and 3) of inhabitants in Nord-Trøndelag county aged ≥20 years performed in 1995-97 (N = 92,936) and 2006-08 (N = 94,194). Attendance rates were 70 and 42%, respectively. Respondents with chronic MSCs were identified through the screening question "Have you during the last year continuously for at least 3 months had pain and/or stiffness in muscles and joints?" The reliability of the screening question was evaluated in a random sample of participants (N = 563).

RESULTS

The reliability of the screening question was good (kappa value 0.63, 95% confidence interval [CI] 0.53-0.73). In HUNT 3, 48% had chronic MSCs and 20% had chronic widespread MSCs. The age-adjusted prevalence of chronic MSCs was higher (P < 0.001) in HUNT 3 (47.9%, 95% CI 47.6-48.2) compared with HUNT 2 (44.8%, 95% CI 44.5-45.2), evident for both genders, and most prominent in the age group 20-29 years. Chronic widespread MSCs were more common in HUNT 3 than in HUNT 2 among women (28.2 vs 26.0%, P < 0.001). Increased prevalence during the 11-year period was also found in supplementary analyses evaluating the influence of differences in participation rate.

CONCLUSIONS

The prevalence of chronic MSCs and chronic widespread MSCs is high. The prevalence of chronic MSCs increased during the 11-year period. A nonresponse bias interfering with the comparisons over time could not completely be ruled out.

The implications of chronic pain models for rehabilitation of distal radius fracture

Distal radius fracture (DRF) is the most common fracture and usually occurs as a result of a fall. Most patients recover following DRF with minimal residual pain or disability; however, a small subset of patients continue to experience pain and disability even one year after the injury. Currently, there are no practice guidelines for early identification and treatment of patients who are potentially at greater risk of developing these adverse outcomes. As a result, hand therapy management of patients following DRF does not incorporate screening of these at-risk patients. The objective of this paper is to apply constructs from learned helplessness and cognitive-behavioural models of chronic pain in assessing the psychosocial risk profile of patients following DRF. We have also integrated key findings derived from studies addressing personal and life-style factors in assessing this risk profile. This framework is proposed as a basis to categorize patients as higher or lower psychosocial risk for developing chronic pain and disability following DRF. We outline a model depicting the RACE approach (Reducing pain, Activating, Cognitive reshaping, Empowering) towards the management of patients following DRF. The model suggests that patients with minimal psychosocial risk factors are managed based on their injury profile and those with higher psychosocial risk are treated with the risk-based RACE approach. Using a biopsychosocial RACE approach to prognosis and treatment, hand therapy intervention can be customized for patients recovering from DRF. In future, researchers can conduct clinical trials to compare the RACE-based treatment approach to routine hand therapy in mitigating the risk of chronic pain and disability in patients with elevated risk profile for adverse outcomes following DRF.
