Abstract BackgroundTo investigate the association between different clinical endpoints and the presence of upper extremity work-related musculoskeletal disorders (WMSDs) in a healthy working population. Furthermore, the influence of socio-demographic, work-related and individual predictors on different endpoints was examined.MethodsTwo self-completion questionnaires were administered to 70 workers and employees. In addition, a standardized physical examination and an industry test were performed in this cross-sectional study. Correlations between WMSDs and clinical endpoints were analysed with the Spearman method. Depending on the type of dependent endpoint, linear or logistic multivariate regression models were used to study the strength of associations with a pre-defined set of potential influencing factors.ResultsThe prevalence of WMSDs was 56% (39/70). Correlations between WMSDs and the DASH score / pain under strain (VAS) were by far the strongest ones. Independent predictors could not be identified as risk factors for WMSDs, but there was some correlation between these factors.ConclusionsThe DASH score, used in the primary analysis of the study data, remains a close candidate for best surrogate endpoint for WMSD detection. The VAS has to be examined for this role in further research. Our analysis should help to improve the methodological quality of future occupational health studies through improved standards.Trial registrationThis study was registered at ClinicalTrials.org with the identifier NCT03014128, on January 9, 2017.

A wide range of endpoints and methods of analysis can be observed in occupational health studies in the context of work-related musculoskeletal disorders (WMSDs). Comparison of study results is therefore difficult. We investigated the association between different clinical endpoints and the presence of upper extremity WMSDs in a healthy working population. Furthermore, the influence of socio-demographic, work-related, and individual predictors on different endpoints was examined. Two self-administered questionnaires were distributed to 70 workers and employees. In addition, a standardized physical examination and an industry test were performed in this cross-sectional study. Correlations between WMSDs and clinical endpoints were analyzed with the Spearman method and prediction ellipses. Multiple regression models were used to study the strength of associations with a pre-defined set of potential influencing factors. The prevalence of WMSDs was 56% (39/70). Disabilities of Arm, Shoulder, and Hand (DASH) score/pain under strain showed the strongest correlations with WMSDs. When analyzing the correlation between WMSDs and pre-selected predictors, none of the predictors could be identified as a risk factor. The DASH score remains a close candidate for best surrogate endpoint for WMSDs detection. Standardized analysis methods could improve the methodological quality of future occupational health studies.

And Control

To assess the prevalence of upper extremity work-related musculoskeletal disorders (WMSDs) among surgical device mechanics compared to a control group, a total of 70 employees were included and assigned to three occupational groups (grinders, packers, and control). Personal factors, work exposure, manual skill, and complaints were assessed by two self-administered questionnaires and an industry test. WMSDs were diagnosed in a standardised clinical examination. The two-one-sided t-tests (TOST) procedure was used to test the clinical equivalence of the respective grinding and packaging groups vs. the control group in terms of the Disabilities of the Arm, Shoulder and Hand (DASH) score. Thirty-nine study participants (56%) experienced at least one WMSD at the elbow, forearm, and/or wrist, mainly with signs of epicondylitis and nerve entrapment at the medial elbow. The risk of grinders developing upper extremity WMSD was about 2.5-times higher and packers had an 8.6-fold higher risk of a clinically relevant DASH > 29 compared to the control group. However, these differences were not statistically significant. The groups were also proven to be clinically equivalent in terms of DASH score. Surgical device mechanics do not seem to have worse DASH values or be at higher risk of upper limb WMSDs compared to a control group. This is the first study to analyse and compare different workplaces in this industry that are also common in other industries.

Playing Time

To play a musical instrument, such as the violin or flute, requires controlled, adequate movements performed by the arm, hand, and fingers in an asymmetric playing posture. The movements are monotonous and often of long duration, involving static and repetitive muscle work of the upper extremity and neck-shoulder muscles. This situation may lead to an increased risk of contracting musculoskeletal problems. The aim of this cross-sectional study was to investigate the relationship between physical workload, defined as playing posture and playing time per week, and musculoskeletal disorders in music teachers. A questionnaire was distributed, with items based on work-related musculoskeletal disorders and physical working conditions. The study population consisted of music teachers employed at a Swedish municipal music school. Out of 61 music teachers, 47 (77%) agreed to participate, including 28 women and 19 men. The study group was divided into two groups depending on if they had an asymmetric or symmetric upper extremity/back playing position. Of the total participants, 77% reported musculoskeletal disorders during the preceding 12 months. Female teachers reported significantly more symptoms in the neck, shoulders, and upper back than male teachers. Music teachers with an asymmetric playing posture had significantly more musculoskeletal disorders than music teachers with a symmetric playing posture. This study demonstrates that an asymmetric playing position may affect the amount of musculoskeletal disorders in the upper extremity and back.

Upper Extremity Musculoskeletal Disorders

Background. Work-related upper extremity musculoskeletal disorders (WUEDs) often present remarkable health and economic burdens on society. Occupational barbers are usually neglected both in research and policy actions, mainly in developing countries, and hence are likely subjected to the conditions. So far, information about factors that influence WUEDs among barbers in Ethiopia is inconclusive. Therefore, this study aimed to evaluate prevalence and factors associated with WUEDs among barbers in Gondar town, Ethiopia. Methods. We conducted a cross-sectional study from March to April 2018. A sample of 424 participants were recruited using systematic random sampling technique. A standardized Nordic Musculoskeletal Questionnaire was pretested and interviewer-administered for data collection. The data were analyzed by SPSS version 20 software. We set statistical significances at <0.05 p value with 95% confidence intervals (CI) and computed odds ratios to evaluate strength of associations. Results. The response rate was 98.3% (N=417). The mean age was 26.39 (SD + 4.805) years. The prevalence of upper extremity musculoskeletal disorders over the past 12 months was 56.8% (N=237). Upper back pain was observed in 38.8% (N=162) participants, whereas shoulder (27.1% (N=113)), neck pain and elbow/forearms (each 29.3% (N=122)), and wrists/hand disorders (32.4% (N=135)) were the common body sites indicated. Age (AOR: 2.614; 95% CI (1.287, 5.307)), alcohol use (AOR: 3.556; 95% CI (2.212, 5.717)), frequent standing (AOR: 1.536; 95% CI (1.006, 2.346)), physical exercises (AOR: 1.938; 95% CI (1.216, 3.089)), and low monthly salary (AOR: 3.125; 95% CI (1.157, 5.441)) were factors associated with work-related upper extremity disorders. Conclusions. Work-related upper extremity disorder is common among hairdressing professionals. Worksite health promotions targeted to lifestyle behaviors, like physical exercise and alcohol consumption require urgent public health actions in Ethiopia. Moreover, adaption of flexible work postures and proper management of workplace conditions related to aging workforces are also imperative to trace the complaints.

The Mean

Numerous investigators have performed cross-sectional studies of upper extremity musculoskeletal disorders (UEMSDs) among industrial workers, and modeled the prevalence of these conditions in relation to potential ergonomic exposures and other covariates. However, prospective studies have been rare for a variety of reasons. Results of a cross-sectional study of UEMSDs based on data collected approximately 5 years ago were published in 1999 (Latko et al., 1999). A subset of the workers from this study were available for re-examination approximately 5 years after the first investigation. The survey tools and clinical examination protocols used in the follow-up examinations were largely identical to the baseline procedures, thus permitting direct comparison of results between rounds. Workers from 2 of the 3 employers in the original study were available for the follow-up investigation. Just over 50% of available and eligible workers participated in the follow-up examinations (152 out of 267, or 57%). The mean age at follow-up was almost 48 years (standard deviation = 9.5 years). The mean body mass index (BMI) was 28.9 at follow-up, and just over half of the study participants were male (53%). Most subjects were still employed by the same employer, and most were still in the same jobs. The prevalence and severity of upper extremity symptoms declined significantly in most body regions between baseline and follow-up. In contrast, the prevalence of most upper extremity diagnoses (tendinitis and carpal tunnel syndrome based on symptoms, standardized physical examinations, and/or nerve conduction tests) increased slightly, though not significantly. Relative median-minus-ulnar peak latency differences increased slightly, and significantly, between rounds. There are almost no studies for comparison of results. More prospective studies are needed to better understand the natural history of upper extremity musculoskeletal disorders among workers.

Background: Sickness absence represents a serious problem for industry and Social Security, since many of these workers become beneficiaries by the National Social Security Institute. The relationship between the factors that lead to dismissal and granting benefits to workers in the industry has yet to be studied. Objective: To determine the relationship between social and occupational factors to granting sickness benefits to industrial workers affected by Work-related Musculoskeletal Disorders. Methods: This is a retrospective cross-sectional with quantitative approach study involving industrial workers. The data contained in the evaluation form of workers who were admitted between 2016 and 2020 in a Reference Centers in Occupational Health were used. The data were descriptively evaluated and a logistic regression model was used to estimate the factors which are related to the type of assistance granted to the workers. Results: 108 medical records of industry workers were evaluated and 56.5% received the accident-related sickness assistance benefit (B-91). Most are workers from industry with light demand (95.4%), who perform repetitive work (93.5%), intense work pace (83.3%), with the shoulder being the region most frequently affected (85.2%). The factors that were significantly related to grating accidental-related sickness benefit: time in the current occupation (OR = 1.01), work involving cervical spine flexion (OR = 4.68), participation in the rehabilitation program (OR = 31.27) and referral to specialist consultations (OR = 3.10). Conclusion: The creation of institutional programs in the industry and the implementation of public health and social security policies are necessary to manage these factors.
