Health risk assessment and prevalence of work-related musculoskeletal disorders among the aged brick molders, in India.

The Brickfield Industry is the major and oldest informal industry in India, where millions of brickfield workers make their livelihood. Aged brickfield workers are also involved in different activities in the brickfield, especially in brick mold activities owing to poor socioeconomic conditions. A cross-sectional study was designed to determine the prevalence of work-related musculoskeletal disorders among the aged brick molders and compare them with aged control subjects. A Nordic Questionnaire was applied to assess the discomfort felt among both groups of workers and the Rapid Upper Limb Assessment (RULA) method was used to evaluate posture during their job. The RULA posture analysis showed that the posture adopted by aged brick molders required changes immediately. The result of the ART tool also stated that the brick molding activities' exposure level was high and required further investigation urgently. The study concluded that due to working in a forward bending posture for a prolonged period, aged brickmolders suffered from severe low back and knee pain along with upper-limb disorders due to repetitive activities.

Evidence-Based Guideline for the management of osteoporosis in men.

Historically, osteoporosis has been viewed as a disease of women, with research, trials of interventions and guidelines predominantly focused as such. It is apparent, however, that this condition causes a substantial health burden in men also, and that its assessment and management must ultimately be addressed across both sexes. In this article, an international multidisciplinary working group of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases presents GRADE-assessed recommendations for the diagnosis, monitoring and treatment of osteoporosis in men. The recommendations are based on a comprehensive review of the latest research related to diagnostic and screening approaches for osteoporosis and its associated high fracture risk in men, covering disease burden, appropriate interpretation of bone densitometry (including the use of a female reference database for densitometric diagnosis in men) and absolute fracture risk, thresholds for treatment, and interventions that can be used therapeutically and their health economic evaluation. Future work should specifically address the efficacy of anti-osteoporosis medications, including denosumab and bone-forming therapies.

Feasibility of using low-cost markerless motion capture for assessing functional outcomes after lower extremity musculoskeletal cancer surgery.

BACKGROUND: Physical limitations are frequent and debilitating after sarcoma treatment. Markerless motion capture (MMC) could measure these limitations. Historically expensive cumbersome systems have posed barriers to clinical translation. RESEARCH QUESTION: Can inexpensive MMC [using Microsoft KinectTM] assess functional outcomes after sarcoma surgery, discriminate between tumour sub-groups and agree with existing assessments? METHODS: Walking, unilateral stance and kneeling were measured in a cross-sectional study of patients with lower extremity sarcomas using MMC and standard video. Summary measures of temporal, balance, gait and movement velocity were derived. Feasibility and early indicators of validity of MMC were explored by comparing MMC measures i) between tumour sub-groups; ii) against video and iii) with established sarcoma tools [Toronto Extremity Salvage Score (TESS)), Musculoskeletal Tumour Rating System (MSTS), Quality of life-cancer survivors (QoL-CS)]. Statistical analysis was conducted using SPSS v19. Tumour sub-groups were compared using Mann-Whitney U tests, MMC was compared to existing sarcoma measures using correlations and with video using Intraclass correlation coefficient agreement. RESULTS: Thirty-four adults of mean age 43 (minimum value-maximum value 19-89) years with musculoskeletal tumours in the femur (19), pelvis/hip (3), tibia (9), or ankle/foot (3) participated; 27 had limb sparing surgery and 7 amputation. MMC was well-tolerated and feasible to deliver. MMC discriminated between surgery groups for balance (p<0.05*), agreed with video for kneeling times [ICC = 0.742; p = 0.001*] and showed moderate relationships between MSTS and gait (p = 0.022*, r = -0.416); TESS and temporal outcomes (p = 0.016* and r = -0.0557*), movement velocity (p = 0.021*, r = -0.541); QoL-CS and balance (p = 0.027*, r = 0.441) [* = statistical significance]. As MMC uncovered important relationships between outcomes, it gave an insight into how functional impairments, balance, gait, disabilities and quality of life (QoL) are associated with each other. This gives an insight into mechanisms of poor outcomes, producing clinically useful data i.e. data which can inform clinical practice and guide the delivery of targeted rehabilitation. For example, patients presenting with poor balance in various activities can be prescribed with balance rehabilitation and those with difficulty in movements or activity transitions can be managed with exercises and training to improve the quality and efficiency of the movement. SIGNIFICANCE: In this first study world-wide, investigating the use of MMC after sarcoma surgery, MMC was found to be acceptable and feasible to assess functional outcomes in this cancer population. MMC demonstrated early indicators of validity and also provided new knowledge that functional impairments are related to balance during unilateral stance and kneeling, gait and movement velocity during kneeling and these outcomes in turn are related to disabilities and QoL. This highlighted important relationships between different functional outcomes and QoL, providing valuable information for delivering personalised rehabilitation. After completing future validation work in a larger study, this approach can offer promise in clinical settings. Low-cost MMC shows promise in assessing patient's impairments in the hospitals or their homes and guiding clinical management and targeted rehabilitation based on novel MMC outcomes affected, therefore providing an opportunity for delivering personalised exercise programmes and physiotherapy care delivery for this rare cancer.

Modifiable prognostic factors of high societal costs among people on sick leave due to musculoskeletal disorders: findings from an occupational cohort study.

OBJECTIVES: The objective was to identify modifiable prognostic factors of high societal costs among people on sick leave due to musculoskeletal disorders, and to identify modifiable prognostic factors of high costs related to separately healthcare utilisation and productivity loss. DESIGN: A prospective cohort study with a 1-year follow-up. PARTICIPANTS AND SETTING: A total of 549 participants (aged 18-67 years) on sick leave (≥ 4 weeks) due to musculoskeletal disorders in Norway were included. OUTCOME MEASURES AND METHOD: The primary outcome was societal costs aggregated for 1 year of follow-up and dichotomised as high or low, defined by the top 25th percentile. Secondary outcomes were high costs related to separately healthcare utilisation and productivity loss aggregated for 1 year of follow-up. Healthcare utilisation was collected from public records and included primary, secondary and tertiary healthcare use. Productivity loss was collected from public records and included absenteeism, work assessment allowance and disability pension. Nine modifiable prognostic factors were selected based on previous literature. Univariable and multivariable binary logistic regression analyses were performed to identify associations (crude and adjusted for selected covariates) between each modifiable prognostic factor and having high costs. RESULTS: Adjusted for selected covariates, six modifiable prognostic factors associated with high societal costs were identified: pain severity, disability, self-perceived health, sleep quality, return to work expectation and long-lasting disorder expectation. Depressive symptoms, work satisfaction and health literacy showed no prognostic value. More or less similar results were observed when high costs were related to separately healthcare utilisation and productivity loss. CONCLUSION: Factors identified in this study are potential target areas for interventions which could reduce high societal costs among people on sick leave due to musculoskeletal disorders. However, future research aimed at replicating these findings is warranted. TRIAL REGISTRATION NUMBER: NCT04196634, 12 December 2019.

Comparing risk assessment methods for work-related musculoskeletal disorders with in vivo joint loads during manual materials handling.

The validity of observational methods in ergonomics is still challenging research. Criterion validity in terms of concurrent validity is the most commonly studied. However, studies comparing observational methods with biomechanical values are rare. Thus, the aim of this study is to compare the Ovako Working Posture Analysing System (OWAS) and the Rapid Entire Body Assessment (REBA) with in vivo load measurements at hip, spine, and knee during stoop and squat lifting of 14 participants. The results reveal that OWAS and REBA action levels (AL) can distinguish between different in vivo load measurements during manual lifting. However, the results also reveal that the same OWAS- and REBA-AL do not necessarily provide equal mean values of in vivo load measurements. For example, resultant contact force in the vertebral body replacement for squat lifting ranged from 57% body weight (%BW) in OWAS-AL1 to 138%BW in OWAS-AL3 compared to 46%BW in REBA-AL0 and 173%BW in REBA-AL3. Furthermore, the results suggest that the performed squat lifting techniques had a higher risk for work-related musculoskeletal disorders than the performed stoop lifting techniques.

Collaborative care model versus usual care for the management of musculoskeletal and co-existing mental health conditions: a randomised feasibility mixed-methods study.

OBJECTIVE: This study aimed to assess the feasibility of a future trial comparing the collaborative care model with usual care for patients with musculoskeletal conditions and co-existing symptoms of anxiety and depression. DESIGN: A single-centre, parallel-arm, one-to-one, randomised controlled trial design using a mixed-methods approach was used. semistructured interviews and focus groups were conducted post intervention with all participants and staff respectively to explore acceptability towards the model and identify recommendations for improvements. SETTING: An orthopaedic rehabilitation outpatient tertiary hospital. PARTICIPANTS: Adult patients with musculoskeletal conditions and co-existing moderate or severe symptoms of anxiety and depression attending outpatient therapy appointments. INTERVENTION: The collaborative care model consisted of a tailored management programme to facilitate the integration of care provided by physical and mental healthcare professionals. A case manager screened and coordinated targeted mental health support for participants. Participants allocated to usual care had no support from the case manager. MAIN OUTCOMES MEASURE: Feasibility indicators (rates of recruitment, randomisation and retention), acceptability of clinical outcome measures, usage of additional resources and cost of intervention implementation. RESULTS: Of the 89 patients who provided consent to take part, 40 participants who matched the eligibility criteria were randomised to either the intervention (n=20) or usual care arm (n=20). Overall adherence to the intervention was 58.82%, while the withdrawal rate was 37.5% at 6 months. All of the 27 participants who were retained completed self-reported outcomes. Qualitative data highlighted that integrated mental health support was favourably perceived. In addition to prenegotiating protected psychology time, the need for operationalised communication between the case manager and clinicians was identified as a recommendation for a future trial. CONCLUSIONS: The trial and intervention were acceptable to patients and healthcare professionals. While the findings demonstrate the feasibility of trial recruitment, a future trial will require optimised retention strategies to improve adherence and withdrawal rates. TRIAL REGISTRATION NUMBER: NCT05018039.

Health trends in Canada 1990-2019: An analysis for the Global Burden of Disease Study.

OBJECTIVE: Monitoring trends in key population health indicators is important for informing health policies. The aim of this study was to examine population health trends in Canada over the past 30 years in relation to other countries. METHODS: We used data on disability-adjusted life years (DALYs), years of life lost (YLL), years lived with disability, life expectancy (LE), and child mortality for Canada and other countries between 1990 and 2019 provided by the Global Burden of Disease Study. RESULTS: Life expectancy, age-standardized YLL, and age-standardized DALYs all improved in Canada between 1990 and 2019, although the rate of improvement has leveled off since 2011. The top five causes of all-age DALYs in Canada in 2019 were neoplasms, cardiovascular diseases, musculoskeletal disorders, neurological disorders, and mental disorders. The greatest increases in all-age DALYs since 1990 were observed for substance use, diabetes and chronic kidney disease, and sense organ disorders. Age-standardized DALYs declined for most conditions, except for substance use, diabetes and chronic kidney disease, and musculoskeletal disorders, which increased by 94.6%, 14.6%, and 7.3% respectively since 1990. Canada's world ranking for age-standardized DALYs declined from 9th place in 1990 to 24th in 2019. CONCLUSION: Canadians are healthier today than in 1990, but progress has slowed in Canada in recent years in comparison with other high-income countries. The growing burden of substance abuse, diabetes/chronic kidney disease, and musculoskeletal diseases will require continued action to improve population health.

RéSUMé: OBJECTIF: La surveillance des tendances des indicateurs clés de la santé de la population est importante pour éclairer les politiques de santé. Dans cette étude, nous avons examiné les tendances de la santé de la population au Canada au cours des 30 dernières années par rapport à d'autres pays. MéTHODES: Nous avons utilisé des données sur les années de vie ajustées en fonction de l'incapacité (DALY), les années de vie perdues (YLL), les années vécues avec un handicap, l'espérance de vie (LE) et la mortalité infantile pour le Canada et d'autres pays entre 1990 et 2019, fournies par l'Étude mondiale sur le fardeau de la maladie. RéSULTATS: L'espérance de vie, les YLL ajustées selon l'âge et les DALY ajustées selon l'âge ont tous connu une amélioration au Canada entre 1990 et 2019, bien que le taux d'amélioration se soit stabilisé depuis 2011. Les cinq principales causes des DALY pour tous les âges au Canada en 2019 étaient les néoplasmes, les maladies cardiovasculaires, les affections musculosquelettiques, les affections neurologiques et les troubles mentaux. Les plus fortes augmentations des DALY pour tous les âges depuis 1990 ont été observées pour l'usage de substances, le diabète et les maladies rénales chroniques, ainsi que les troubles des organes sensoriels. Les DALY ajustées selon l'âge ont diminué pour la plupart des conditions, à l'exception de l'usage de substances, du diabète et des maladies rénales chroniques, ainsi que des troubles musculosquelettiques, qui ont augmenté de 94,6 %, 14,6 % et 7,3 % respectivement depuis 1990. Le classement mondial du Canada pour les DALY ajustées selon l'âge est diminué de la 9ième place en 1990 à la 24ième place en 2019. CONCLUSION: Les Canadiens sont en meilleure santé aujourd'hui qu'en 1990, mais les progrès se sont ralentis ces dernières années par rapport à d'autres pays à revenu élevé. La croissance du fardeau lié à l'abus de substances, au diabète/maladies rénales chroniques et aux affections musculosquelettiques exigera des actions continues pour améliorer la santé de la population.

[Determinants of use of rehabilitation services before entering disability pension: Time series analysis of insured members of the German Pension Insurance Federation in Berlin and Brandenburg]. / Determinanten zur Inanspruchnahme von Rehabilitationsleistungen vor Eintritt in die Erwerbsminderung: Zeitreihenanalyse von Versicherten der Deutschen Rentenversicherung Bund in Berlin und Brandenburg.

BACKGROUND: The age-standardized application rate for medical rehabilitation services of the German Pension Insurance Association has been declining since 2009. Two of the most frequent reasons for applying for rehabilitation services represent musculoskeletal disorders and mental disorders. The aim of this analysis was to identify factors influencing the utilization of rehabilitation services in the federal states of Berlin and Brandenburg. METHODS: The explorative time series analysis is based on a research dataset of the German Pension Insurance Federation. Insured persons of the German Pension Insurance Federation from the federal states of Berlin and Brandenburg with a diagnosis of musculoskeletal disorders or mental disorders were included. Descriptive differences in targeted and prognostic parameters were calculated using chi-square and t-test statistics. Predictive parameters for the utilization of medical rehabilitation services were calculated using binary, logistic regression analyses. RESULTS: A total of 11,257 insured cases were examined. For the population of insured persons from Berlin, the use of medical rehabilitation services showed significant prognostic variables for gender, age at retirement, marital status, level of education, occupational requirement level, total accumulated earning points, gross pension level, status of a temporary pension, health insurance status, and diagnosis group. For Brandenburg, significant prognostic variables were found for age at retirement, marital status, nationality, education level, occupational requirement level, total accumulated earning points, status of a temporary pension, occupational sector, and diagnosis group. CONCLUSION: In Berlin and Brandenburg mental disorders and sociodemographic parameters are associated with an increased probability of not claiming medical rehabilitation services before the onset of reduced earning capacity. It remains to be investigated which mechanisms cause people with mental disorders to make no use of medical rehabilitation services. Future analyses should examine isolated interaction mechanisms for the utilization of medical rehabilitation services, especially in the case of existing F-diagnoses. In addition, explanations for different influencing variables between states remain to be explored.

Drug persistence in patients with rheumatic and musculoskeletal diseases during a major economic crisis: results from a nationwide cross-sectional online survey.

To evaluate the drug persistence in patients with rheumatic and musculoskeletal diseases (RMDs) during the current economic crisis in Lebanon and to estimate predictors of persistence. A nationwide multicentric cross-sectional study using an online questionnaire was conducted in Lebanon with patients with chronic inflammatory rheumatic diseases (CIRDs) and non-inflammatory RMDs controls between July and October 2022. Disease-modifying antirheumatic drugs (DMARDs) were categorized as conventional synthetic (cs), biological (b), subcutaneous (SC) or intravenous (IV), and targeted synthetic (ts). Persistence was defined as "number of tablets or injections taken during the past month versus prescribed". The percentage of patients who discontinued or changed treatment due to cost or non-availability was reported. Factors associated with persistence were identified using multivariable linear regression. The study included 317 patients with RMDs (286 CIRDs); mean age 49.5 years, 68% females, 58% reporting currently low economic level. Persistence at one month was low for tsDMARDs (36%) and bDMARDs (SC55%, IV63%), and acceptable for csDMARDs (88%). A persistence ≥80% was found in 23.3% of patients on tsDMARDs, 42.9% on SC bDMARDs, 45.0% on IV bDMARDs, and 74.7% on csDMARDs. During the past 6 months, 55.8% of CIRD patients discontinued or changed treatment due to non-availability (45.3%) or cost (21.2%). Persistence was positively associated with finding alternative sources such as buying abroad (36%), depending on friends or families abroad (20%), charities (10%), and negatively associated with unemployment and low financial status. Persistence was significantly compromised for essential antirheumatic drugs and was mostly driven by treatment unavailability and cost.

Muscle function assessment of the hindlimbs in healthy dogs using acoustic myography.

INTRODUCTION: Impaired muscle function is a frequent consequence of musculoskeletal disorders in dogs. Musculoskeletal disorders, especially stifle joint diseases, are common in dogs and assessment of muscle function in dogs is clinically relevant. Acoustic myography (AMG) is a non-invasive method to assess muscle activity. Quantifying muscle function in normal dogs could help identify clinically relevant changes in dogs with orthopaedic disease and allow targeted interventions to improve recovery in these. The objectives of the study were to characterize hindlimb muscle function in healthy dogs using AMG and to investigate the repeatability and reproducibility of AMG in dogs. METHODS: Healthy dogs (15-40 kg) without musculoskeletal disorders were recruited and screened for eligibility to participate in the study. The muscle activity in four hindlimb muscles related to the stifle was assessed using AMG. The degree of symmetry between the hindlimbs in these dogs was investigated and the reliability of AMG was evaluated. RESULTS AND CONCLUSIONS: The study population comprised 21 dogs. Reference intervals and symmetry indices for AMG scores of the hindlimb muscles were identified, with highest variability for the E-scores. For all AMG-scores, same-day variation was lower than between days variation, and both were lowest for S- and T-scores. Further investigation is needed to establish if AMG can enable discrimination between dogs with altered muscle function and healthy dogs.

The Price of Pain: Workers Compensation Costs for Musculoskeletal Claims in the State of Kansas, 2014-2022.

OBJECTIVE: The aim of the study is to describe cost and frequency of work-related musculoskeletal disorders in Kansas. METHODS: Data were provided by the Kansas Department of Labor and included all closed workers' compensation claims entailing indemnity and medical costs from 2014 to 2022. RESULTS: Work-related musculoskeletal disorder claims entailed a median total cost of $20,097. Medical comprised 48.4% of costs, indemnity 46.4%, and legal 5.2%. The most frequently injured and costliest body part was the shoulder. Manufacturing comprised 28.4% of claims, followed by health care and office. Lifting was the most common cause, generating 32.0% of claims. Education, transportation, and mining were among industries with above average claim rates. CONCLUSIONS: Very few studies use workers' compensation data to assess work-related musculoskeletal disorder costs. This study introduces a state not yet analyzed and presents more recent years of data than available in the literature.

Trends in the disease burden of musculoskeletal disorders in Mexico from 1990-2019.

OBJECTIVE: This study aimed to describe the disease burden and trends of musculoskeletal (MSK) disorders in Mexico from 1990 to 2019. METHOD: A cross-sectional study using systematic analysis from the Global Burden of Disease Study 2019 (GBD study 2019) was performed to analyze data on MSK disorders and estimate crude and age-standardized rates per 100,000 population concerning disease prevalence, incidence, mortality, disability-adjusted life-years (DALY), and years lived with disability (YLD). The average annual percentage change (AAPC) was calculated using the joinpoint regression. RESULTS: In 2019, there were 4.8 million (95% UI 4.3, 5.4) new cases and 3,312 (95% UI 2201, 4,790) deaths attributable to MSK disorders. In 2019, MSK disorders ranked first, increasing from 1990 (second rank) for the YLD in Mexico. Subnational variations were identified, with the state of Oaxaca having the highest age-standardized incidence rate (ASIR) per 100,000 population in 2019. Joinpoint analysis revealed a significant increase in prevalence in Mexico from 1990 to 2019 (AAPC: 0.14%; 95%CI 0.09-0.19), incidence (AAPC: 0.05%; 95%CI 0.03-0.07), DALY (AAPC: 0.13%; 95%CI 0.04-0.22), and YLD (AAPC: 0.13%; 95%CI 0.02-0.24). Among the risk factors, occupational ergonomic factors and high body mass index (BMI) had the largest influence on MSK disorders. CONCLUSIONS: In Mexico, we observed an increase the national burden of MSK disorders from 1990 to 2019. Specific determinants, such as occupational ergonomic factors and high BMI, contribute to the MSK disorder burden. The burden of MSK disorders requires an improved and prompt assessment to plan valuable diagnostic and management approaches. Key Points • In Mexico, the burden of musculoskeletal (MSK) disorders increased from 1990 to 2019. • Specific risk factors, such as occupational ergonomic factors and high body mass index, contribute to the MSK disorder burden.

Physiotherapists' engagement in work ability and return to work issues of patients with musculoskeletal disorders. A cross-sectional survey in Norway.

BACKGROUND: Work and health are a national priority in Norway, and leading health authorities call for treatment approaches that incorporate these perspectives. We have little knowledge of how physiotherapists in private practice integrate the work perspective during the treatment of patients with musculoskeletal disorders. Thus, the purpose of this study was to gain more insight into the way physiotherapists in Norway integrate the aspect of work. METHODS: In 2021, all 2650 privately practising members of the Norwegian Physiotherapist Association received a web-based survey that was answered by 514 physiotherapists. The survey included questions about treatment approaches, competencies, and collaboration with other health professionals in the context of promoting work participation. RESULTS: 91% of the physiotherapists reported that they play an important role in assessing work ability. 75% were confident in assessing the patients' work ability, while 25% stated that they have little or some competence. 49% of the physiotherapists often contacted the general practitioner (GP) to discuss patients' ability to work, and 19% were often contacted by the GP. Only 14% stated that they were invited to participate in dialogue meetings with the Norwegian Labour and Welfare Administration. 28% of the physiotherapists reported that insufficient knowledge about social security issues was an obstacle in promoting the patient's work participation. The physiotherapists believed that increased use of standardised assessment tools, better knowledge of social security issues, and closer collaboration with other professionals may strengthen their role in promoting work participation. DISCUSSION AND CONCLUSION: Although physiotherapists promote work participation when treating patients on sick leave, limited communication with the stakeholders, and inadequate knowledge of social security issues pose an obstacle. To strengthen the physiotherapist's role in the return-to-work facilitation, work and health should become a separate subject in basic and advanced education programmes for physiotherapists.

Global, regional and national temporal trends in prevalence for musculoskeletal disorders in women of childbearing age, 1990-2019: an age-period-cohort analysis based on the Global Burden of Disease Study 2019.

OBJECTIVES: To provide an overview and in-depth analysis of temporal trends in prevalence of musculoskeletal (MSK) disorders in women of childbearing age (WCBA) at global, regional and national levels over the last 30 years, with a special focus on their associations with age, period and birth cohort. METHODS: Estimates and 95% uncertainty intervals (UIs) for MSK disorders prevalence in WCBA were extracted from the Global Burden of Diseases, Injuries and Risk Factors Study 2019. An age-period-cohort model was adopted to estimate the overall annual percentage change of prevalence (net drift, % per year), annual percentage change of prevalence within each age group (local drift, % per year), fitted longitudinal age-specific rates adjusted for period deviations (age effects) and period/cohort relative risks (period/cohort effects) from 1990 to 2019. RESULTS: In 2019, the global number of MSK disorders prevalence in WCBA was 354.57 million (95% UI: 322.64 to 387.68). Fifty countries had at least one million prevalence, with India, China, the USA, Indonesia and Brazil being the highest accounting for 51.03% of global prevalence. From 1990 to 2019, a global net drift of MSK disorders prevalence in WCBA was -0.06% (95% CI: -0.07% to -0.05%) per year, ranging from -0.09% (95% CI: -0.10% to -0.07%) in low-middle sociodemographic index (SDI) region to 0.10% (95% CI: 0.08% to 0.12%) in high-middle SDI region, with 138 countries presenting increasing trends, 24 presenting decreasing trends and 42 presenting relatively flat trends. As reflected by local drift, higher SDI regions had more age groups showing rising prevalence whereas lower SDI regions had more declining prevalence. Globally, an increasing occurrence of MSK disorders prevalence in WCBA beyond adolescent and towards the adult stage has been prominent. Age effects illustrated similar patterns across different SDI regions, with risk increasing with age. High SDI region showed generally lower period risks over time, whereas others showed more unfavourable period risks. High, high-middle and middle SDI regions presented unfavourable prevalence deteriorations, whereas others presented favourable prevalence improvements in successively birth cohorts. CONCLUSIONS: Although a favourable overall temporal trend (net drift) of MSK disorders prevalence in WCBA was observed over the last 30 years globally, there were 138 countries showing unfavourable rising trends, coupled with deteriorations in period/cohort risks in many countries, collectively raising concerns about timely realisation of the Targets of Sustainable Development Goal. Improvements in the MSK disorders-related prevention, management and treatment programmes in WCBA could decline the relative risk for successively younger birth cohorts and for all age groups over period progressing.

Prevalence, diagnosis and management of musculoskeletal disorders in elite athletes: A mini-review.

Musculoskeletal injuries in elite sports are ones of the most impact issue because their remarkable impact on performance caused by drastic absence of training and competition and a progressive deterioration in physical health, emotional and social athletes' dimensions. Also, the prevalence of epidemiologic research found an incidence of musculoskeletal disorders vary within sports and in elite athletes which is even higher as a consequence of higher demand physical performance. This way, the loss of physical performance due to an sport injury impacts not only the individual economic sphere of the professional but also that ofsports entities, reaching, according to some studies, a loss estimated in the range of 74.7 million pounds. Thus, the purpose of this article is to review and to provide an overview of the most common musculoskeletal injuries in elite sports precipitating factors, clinical presentation, evidence-based diagnostic evaluation, and treatment recommendations with a view to preventing medical conditions or musculoskeletal injuries that may alter performance and general health in the elite athletes.

Prevalence of work-related musculoskeletal disorders and quality of life assessment among garment workers in Tiruppur district, Tamil Nadu.

Objectives. The garment industry is a labour-intensive industry, with workers susceptible to musculoskeletal problems, especially those employed in smaller units that lack adequate occupational health provisions. This study aims to determine the prevalence of work-related musculoskeletal disorders (WMSDs) among workers in both large and small garment units and assess their quality of life (QoL). Methods. The study surveyed 746 garment workers, comprising 372 from large units and 374 from small units. Data were collected through the Nordic musculoskeletal questionnaire and the World Health Organization Quality of Life (WHOQOL)-BREF questionnaire, with posture analysis conducted using the rapid upper limb assessment (RULA) and rapid entire body assessment (REBA) scales. Results. The results showed that 32% of workers in large-scale garment units and 43.9% in small-scale garment units reported musculoskeletal symptoms. The occurrence of musculoskeletal disorders (MSDs) was significantly associated with increasing age, smoking, alcohol consumption, job duration, working in shifts and moonlighting. Conclusion. The workers in the garment industry, particularly of small units, are highly susceptible to WMSDs.

Machine learning approach to determine the decision rules in ergonomic assessment of working posture in sewing machine operators.

INTRODUCTION: There are some inherent problems with the use of observation methods in the ergonomic assessment of working posture, namely the stability and precision of the measurements. This study aims to use a machine learning (ML) approach to avoid the subjectivity bias of observational methods in ergonomic assessments and further identify risk patterns for work-related musculoskeletal disorders (WMSDs) among sewing machine operators. METHODS: We proposed a decision tree analysis scheme for ergonomic assessment in working postures (DTAS-EAWP). First, DTAS-EAWP used computer vision-based technology to detect the body movement angles from the on-site working videos to generate a dataset of risk scores through the criteria of Rapid Entire Body Assessment (REBA) for sewing machine operators. Second, data mining techniques (WEKA) using the C4.5 algorithm were used to construct a representative decision tree (RDT) with paths of various risk levels, and attribute importance analysis was performed to determine the critical body segments for WMSDs. RESULTS: DTAS-EAWP was able to recognize 11,211 samples of continuous working postures in sewing machine operation and calculate the corresponding final REBA scores. A total of 13 decision rules were constructed in the RDT, with over 95% prediction accuracy and 83% path coverage, to depict the possible risk tendency in the working postures. Through RDT and attribute importance analysis, it was identified that the lower arm and the upper arms exhibited as critical segments that significantly increased the risk levels for WMSDs. CONCLUSIONS: This study demonstrates that ML approach with computer vision-based estimation and DT analysis are feasible for comprehensively exploring the decision rules in ergonomic assessment of working postures for risk prediction of WMSDs in sewing machine operators. PRACTICAL APPLICATIONS: This DTAS-EAWP can be applied in manufacturing industries to automatically analyze working postures and identify risk patterns of WMSDs, leading to the development of effectively preventive interventions.

Ergonomic risk management process for safety and health at work.

Purpose: The paper aims to provide the main principles and practical aspects of the model, to present the process of identifying, determining the level, as well as assessing and managing occupational and ergonomic risks. Methods: To conduct the research, as well as to identify the influence of various dangerous factors related to the working posture, pace, rhythm of work performance, equipment and individual characteristics of the employee's health condition, methods of complex analysis and synthesis, formal and dialectical logic are used to study the essence of the concept of occupational and ergonomic risks. Additionally, induction and deduction methods are used to examine the cause-and-effect relationships between dangers, dangerous factors, dangerous event, and the severity of consequences to determine the level of occupational and ergonomic risks based on the improved bow-tie model. The proposed approach effectiveness is tested based on the assessment of occupational and ergonomic risks of forest workers (loggers) with the participation of five experts to identify dangerous factors and develop precautionary measures. Results: An algorithm for managing occupational and ergonomic risks has been developed, consisting of eleven steps, which can be divided into three steps: preparatory, main and documented. It has been determined that occupational and ergonomic risk is the probability of a dangerous event occurring due to employee's physical overload and its impact on the severity of damage to the employee's physical health. The level of occupational and ergonomic risk management is determined taking into account the probability (frequency), intensity and duration of physical overload, as well as the employee's adaptation index to physical overload and his/her health index. Conclusion: The novelty is the substantiation of the principles of occupational and ergonomic risk management, which are based on the bow-tie model and predict the impact on the probability and severity of consequences of a dangerous event, taking into account dangerous factors. Forms for drawing up occupational and ergonomic risk maps have been developed, in which it is necessary to consider interaction of occupational hazards and occupational-ergonomic risk - physical overload.

Associations between the Abilitator, a self-reported measurement tool of work ability and functioning, and national register-based indicators of health and employment.

OBJECTIVES: The Abilitator is a recently developed self-reported measurement tool for work ability and functioning of people in a weak labour market position. The aim of this study was to describe how self-reported information gathered with the Abilitator corresponds to information drawn from national registers. DESIGN, SETTING AND PARTICIPANTS: Participants (n=669, mean age 44 years, 55% women) took part in the Work Ability Programme (2020-2023) that provided services for unemployed people with reduced work ability. They filled in the Abilitator questionnaire at the start of the service. Register-based data on participants' health, income and received benefits was drawn from national registers. We evaluated how the different types of indicators concurred. RESULTS: Statistically significant correlations (from weak to moderate) were found between different domains of the Abilitator and register-based data. Also, participants' health status (information on mental health or musculoskeletal disorders) was displayed coherently in the results of the Abilitator. Overall, diagnosed mental health disorders distinguished participants' Abilitator responses more strongly than diagnosed musculoskeletal disorders. CONCLUSIONS: These findings provide further evidence on the applicability of the Abilitator as an instrument to evaluate work ability and functioning of people outside the work force.
