Abstract
The cross-sectional study aimed to investigate the relationship between work-related factors, perceived work fatigue (PWF) and musculoskeletal disorders (MSDs) among handicraft artisans. 364 artisans participated in a questionnaire survey, and a structural equation model (SEM) was developed to explore the direct and indirect relationships between these factors using partial least squares analysis. The SEM explained 98.2% of the variance in MSDs and revealed that exposure to biomechanical factors had a direct impact on PWF and MSDs, with PWF mediating the effect of biomechanical factors on MSDs. Additionally, job demand was found to be positively associated with MSDs, while job control and social support reduced the risk of MSDs. The findings underscore the importance of strategic initiatives to mitigate the risk of developing MSDs among artisans. The study also highlights the potential of SEM as a novel framework for understanding the complex pathogenesis of MSDs in occupational health research.Practitioner summary: The study sought to comprehensively examine the intricate relationships among work-related factors, PWF, and MSDs. To achieve this, an SEM approach was employed to capture both direct and indirect relationships between these factors, employing partial least squares analysis. Findings revealed SEM as an innovative framework for understanding the intricate development of MSDs.

Abstract
BACKGROUND The sculpting craft must adopt awkward postures that lead to musculoskeletal disorders (MSDs). OBJECTIVE This study investigated the prevalence of musculoskeletal discomfort (MD) and its associations with postural risk factors, demographics, and work characteristics among sculptors. They were determined the differences between MDs during the weeks of the study. METHODS A longitudinal study was conducted; MD was investigated using the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). Posture was assessed using the Rapid Upper Limb Assessment method (RULA). Multivariate logistic regression (MLR) models analyzed associations with different factors. ANOVA was used to test for differences in MD prevalence. RESULTS The analysis included 585 responses by body region. The prevalence of MD was high in the lower and upper limbs among sculptors (67.6%), with the lower back, upper arm, neck, and knees being the four most affected regions. Gender (female) (OR = 2.15), marital status (married) (OR = 1.80), health risk (obesity), the dual of a secondary job (OR = 1.94), job stress (OR = 2.10), duration of work (OR = 2.01), and difficulty keeping up with work (OR = 2.00) were significant predictors contributing to the occurrence of MD in different body regions. Only shoulder MD prevalence showed significant differences between study weeks. CONCLUSIONS Sculptors suffer from MD. Demographic and work characteristic factors influence MD prevalence. Postural training, improved adaptation of work organization, and intervention guidance on ergonomic risks may reduce the prevalence of MD and the risk of MSDs in this population.

Abstract
Objectives. Gemstone polishers suffer from musculoskeletal problems due to constrained working postures, substantially influenced by the poor design of conventional gemstone polishing workstations. The present study investigated the effects of three workstation adjustment parameters (illumination at workstation, polishing height, tool post position) on postural angle, muscle activity and perceived postural discomfort in order to develop recommendations for new gemstone polishing workstations. Methods. Twelve professional gemstone polishers performed the polishing task on a prototype test-rig in 27 different test conditions. Taguchi's L27 orthogonal array was employed to estimate the optimum setting for gemstone polishing workstation design. Results. Study variables had a significant influence on postural angles. Polishing height substantially influenced muscle activity and perceived discomfort in the shoulder and lower back region. Tool post position was found to be the determinant factor for forearm muscle activity and perceived discomfort in the wrist/forearm region. Based on the findings, illumination of 1500 lux, polishing at 15 cm above the elbow height and a 20° tool position was recommended. Conclusions. Our findings present an alternative approach to using Taguchi's design of experiment for workstation improvement, which has received very little attention in ergonomics studies. A confirmation test was conducted to validate the study recommendations.

Abstract
BACKGROUND Professional rickshaw driving is a seemingly sedentary occupation and involves many risk factors for work-related musculoskeletal disorders (WMSD). OBJECTIVE To assess the prevalence of work-related musculoskeletal disorders and its associated risk factors among professional rickshaw drivers. METHODS 263 rickshaw drivers were voluntarily recruited from Aligarh, Uttar Pradesh, India. MSD symptoms in the past 12 months and last 7 days were assessed using a self-modified musculoskeletal questionnaire (Nordic Questionnaire). Chi-square tests and binary logistic regression were performed to analyze associations of MSD symptoms between study variables. RESULTS 155 (58.9%) study participants reported MSD symptoms in past 12 months, in lower back (n = 126, 81.3%), leg (n = 122, 78.7%), neck (n = 106, 68.4%) and knee (n = 105, 67.7%); and 121 (46.1%) in last 7 days, in leg (n = 107, 88.4%), lower back (n = 102, 84.3%), neck (n = 89, 73.6%), upper back and knees (n = 87, 71.9%). Binary logistic regression showed relationship between working hours, seat and road condition, average load per ride, rickshaw ride duration, and standing driving with MSD symptoms among rickshaw drivers, especially in the lower back, leg/calf muscles, neck and knees. CONCLUSION The results showed a high prevalence of MSD among all rickshaw drivers, with the neck, lower back, leg/calf muscles and knees being the most affected body parts. In order to avoid adverse effects on the occupational health of rickshaw drivers, ergonomic intervention training is necessary.

Abstract
OBJECTIVE This study aims to investigate the one-year prevalence and the associated factors of work-related musculoskeletal disorders (WMSDs) among furniture manufacturing workers in Guangdong, China. METHODS A cross-sectional study of 4181 (2953 males and 1228 females) furniture manufacturing workers was conducted between September 2019 and December 2019. All information about WMSDs was collected by the electronic version of Chinese Musculoskeletal Questionnaires (CMQ). Descriptive statistics and a binary logistic regression model were used to interpret the data. RESULT The overall prevalence of WMSDs was 31.57%. The WMSD symptoms most commonly occurred in the neck (16.77%), followed by the shoulders (14.90%), ankles/feet (14.64%), hands/wrists (13.30%), upper back (11.48%), and lower back (10.95%). Multiple logistic regression analysis revealed that several individual, labor organization, and ergonomics-related factors conferred significant risks to WMSDs at different body sites. CONCLUSIONS WMSDs remain the major occupational health problem for furniture manufacturing workers. Hence, some effective and feasible protective measures for furniture manufacturing workers are required in order to alleviate the health burden caused by WMSDs.

Abstract
BACKGROUND Studies on the association between long working hours and health have captured only a narrow range of outcomes (mainly cardiometabolic diseases and depression) and no outcome-wide studies on this topic are available. To achieve wider scope of potential harm, we examined long working hours as a risk factor for a wide range of disease and mortality endpoints. METHODS The data of this multicohort study were from two population cohorts from Finland (primary analysis, n=59 599) and nine cohorts (replication analysis, n=44 262) from Sweden, Denmark, and the UK, all part of the Individual-participant Meta-analysis in Working Populations (IPD-Work) consortium. Baseline-assessed long working hours (≥55 hours per week) were compared to standard working hours (35-40 h). Outcome measures with follow-up until age 65 years were 46 diseases that required hospital treatment or continuous pharmacotherapy, all-cause, and three cause-specific mortality endpoints, ascertained via linkage to national health and mortality registers. FINDINGS 2747 (4·6%) participants in the primary cohorts and 3027 (6·8%) in the replication cohorts worked long hours. After adjustment for age, sex, and socioeconomic status, working long hours was associated with increased risk of cardiovascular death (hazard ratio 1·68; 95% confidence interval 1·08-2·61 in primary analysis and 1·52; 0·90-2·58 in replication analysis), infections (1·37; 1·13-1·67 and 1·45; 1·13-1·87), diabetes (1·18; 1·01-1·38 and 1·41; 0·98-2·02), injuries (1·22; 1·00-1·50 and 1·18; 0·98-1·18) and musculoskeletal disorders (1·15; 1·06-1·26 and 1·13; 1·00-1·27). Working long hours was not associated with all-cause mortality. INTERPRETATION Follow-up of 50 health outcomes in four European countries suggests that working long hours is associated with an elevated risk of early cardiovascular death and hospital-treated infections before age 65. Associations, albeit weak, were also observed with diabetes, musculoskeletal disorders and injuries. In these data working long hours was not related to elevated overall mortality.

Abstract
PURPOSE Precision handicraft workers are often exposed to stressful postures and poor working conditions while performing different jobs, that are directly associated with the development of musculoskeletal disorders (MSDs). This cross-sectional study aimed at evaluating the prevalence of MSDs and contributing risk factors among male precision handicraft workers. METHODS 334 handicraft workers involved in different precision activities: 125 gemstone cutters, 98 miniature painters, and 111 metal craft workers, were surveyed. Information about the prevalence of musculoskeletal symptoms and work-related factors was collected using the self-reported questionnaire and direct observation methods, viz. rapid upper limb assessment (RULA) and rapid entire body assessment (REBA). Chi-square test was performed to analyze the association of MSD symptoms between the handicraft occupations. Further, binary logistic regression was used to identify the potential risk factors for MSD symptoms among workers. RESULTS In all occupational groups, most participants reported high prevalence of MSDs primarily in the neck (61.6%), lower back (74.8%), and knee (54.7%) regions. Results revealed that age, work experience, prolonged work hours, sustained awkward posture, continuous work without break, extensive work pressure, and poor job control increased the risk of MSD symptoms in different body regions, while with a higher level of education, MSDs in the neck and lower back regions reduced. CONCLUSION The findings indicated incompatibility between precision handicraft workers and the occupational environment. Logistic regression models showed significant contribution of physical and psychosocial work-related factors in developing MSD symptoms. Ergonomic interventions are imperative to evade adverse consequences on the occupational health of precision craft workers.

Abstract
Objectives. Hand block printing is a highly repetitive and precision job involving tasks such as hitting the wooden hand block with the hands as a hammer, causing chronic mechanical trauma to the ulnar side of the palm. This study aimed to determine the prevalence of work-related hand symptoms, to identify ergonomic risks and musculoskeletal disorders (MSDs) and evidence of mechanical trauma among artisans working in Bagh print of Madhya Pradesh. Methods. Occupational risk involved in the artisan's wrist area was identified using the modified Dutch musculoskeletal questionnaire (MDMQ) and modified Boston hand evaluation questionnaire. The Boston hand evaluation questionnaire helps in the measurement of the severity of the symptoms. A direct observation study was performed to identify the chronic effects of mechanical trauma (CEMT) on artisan's hands. Results. Symptoms like pain, weakness, numbness and tingling were highly prevalent among the artisans, those with experience <3 years were more likely to report pain during working hours (p < 0.001) and those with experience >13 years were more likely to report numbness (p < 0.001) and tingling (p < 0.001). Conclusion. This study supports the evidence that the new artisans are at higher risks of reporting pain and CEMT, including fever and body pain, ultimately causing job loss.

Abstract
BACKGROUND Kolhapuri hand-sewn crafted footwear is one of the well-designed and traditional footwear in India. Many of the processes in these industries are manual. The study was carried out to establish the occurrence of musculoskeletal disorders (MSD) in different body parts of artisans engaged in crafted footwear manufacturing activity. Due to the difficult physical activities carried out by artisans, there was a possibility of evolving different kinds of MSDs. OBJECTIVE To evaluate the prevalence of MSD symptoms in various body regions of crafted footwear manufacturing artisans. This work further aims to assess different working postures. METHODS The existing working environment and the occurrences of MSD indications of 105 artisans of Kolhapuri crafted footwear manufacturing were evaluated in this study. The data collection was done through an interview and using Nordic musculoskeletal questionnaire. The work uses the Rapid Upper Limb Assessment (RULA) method for posture analysis. Multiple regression investigation was used to evaluate different risk factors linked with MSDs symptoms. RESULTS It has been cleared that there are high occurrences of MSD pain between crafted footwear manufacturing artisans. The most frequently affected body areas were low back, neck, hips/thighs/buttocks, shoulder, elbows, hand and wrist, knees and upper back. The final RULA grand total of 6.1 specifies that artisans' posture needs to be change. CONCLUSION The artisans who were associated with the manufacturing of Kolhapuri footwear had a high prevalence of musculoskeletal symptoms. Analysis of data suggests that the necessity of operational implementation program for handcrafted footwear manufacturing artisans.

Abstract
Abstract
Background
Smartphone use has been associated with pain in the upper quadrant; however, the relationship between usage duration and low back pain is still unclear. This study investigated the association between continuous smartphone use up to 30-min and back pain severity and proprioception acuity in patients with chronic low back pain. Fifty-eight patients with chronic mechanical LBP played a game for 10- and 30-min. In each session, pain and back repositioning errors were measured at baseline and immediately after task completion.
Results
Pain significantly but slightly increased following smartphone use, regardless to the duration (after 10 min: mean increase = 0.75 ± 1.17, P value < 0.001, 95% CI 0.44–1.06; after 30 min: mean increase = 0.96 ± 1.93, P value < 0.001, 95% CI 0.44–1.46). However, changes in perceived pain scores were not significantly different between the two tested durations (P value = 0.42). Proprioception repositioning error was not significantly different within the same testing session (mean change = 0.08 ± 1.83, 0.13 ± 1.77, P value = 0.73, 0.58, 95% CI − 0.40–0.56, − 0.60–0.33, for the 10 and 30 min, respectively). The changes in proprioception were not significant between the two-tested durations (P value = 0.56). Further, smartphone addiction did not significantly affect changes in pain and proprioception after game playing, regardless of the duration (P > 0.05).
Conclusions
These findings show that smartphone use slightly increases back pain immediately after continuous use; with no effect on back proprioception within the duration tested in this study. Changes in pain and proprioception were not influenced by smartphone addiction.
