Introduction: The condition of work in handloom weaving industries cause musculoskeletal (MSDS) disorders which are the most prevailing professional problem among weavers. The aim of this research was to determine ergonomic risk factors in the occurrence of musculoskeletal disorders. Method: The present study was done through descriptive cross-section method to assess the risk factors of work-related musculoskeletal disorders of the weavers. Our data collection tools were: demographic questionnaire, job Nordic questionnaire and body map prevalence of musculoskeletal disorders to decide the rate of symptoms. Then, we took film from handloom weavers while wearing to know the condition of their bodies. After reviewing the films, the posture marks was assigned to each duty using the Ergo Intelligence software. At the end, data were analyzed via one-way ANOVA and T-test using SPSS ver.20. Results: The results showed that the most frequent incidence of pain in different organs of the body during last year belonged to neck and shoulder. The average OCRA was 3.65.This indicated that most of the handloom weavers (64.4%) are at high risk. Conclusion: According to the re According to the results of OCRA indices, weavers are at high risk for musculoskeletal injuries, indicating their poor working environment and working conditions, indicating the need for corrective actions.

Job Assessment

Background According to Washington State workers’ compensation data, construction as an industry ranked first in its compensable claims rate of work-related musculoskeletal disorders (WMSD) injuries (Anderson, Adams, Bonauto, Howard, & Silverstein, 2015). Many current physical job assessment tools available for ergonomics practitioners to evaluate work-related musculoskeletal disorder risks of the back, shoulder, hand/wrist and knee are mostly of general purposes. This project sought to identify risk factors pertinent to given industries. The construction industry is used as an example in this demonstration. Approach Four hundred thirty-six construction employees from sixteen companies in the State of Washington were observed and evaluated using commonly used exposure assessment tools: Washington State Checklists (Washington State Department of Labor and Industries, 2004a, b), Strain Index (Moore & Garg, 1995), American Congress of Governmental Industrial Hygienists Lifting Threshold Limit Values (ACGIH, 2005), Liberty Mutual Manual Materials Handling Guidelines (Snook & Ciriello, 1991), Quick Ergonomics Checklist (David et al, 2005; David et al, 2008), and the European Union Vibration Directives (EU, 2002). The physical risk factors that were evaluated are those that have been associated with WMSDs. These risk factors included: awkward postures of the back, shoulder, hand/wrist; lifting; pushing, pulling, carrying; high hand forces (pinching, griping); highly repetitive motions of the hand/wrist; repeated impacts of the hand or knee; vibration (whole body, hand); and any specific tasks with potential WMSD risks but were otherwise not covered in any of the common assessment tools. Following the results of the exposure assessments, a comprehensive physical job evaluation checklist was created by retaining items sensitive to differentiate levels of risks within jobs in the construction industry. From our job evaluations, WMSD risk factors may not be the same between industry groups and as such, industry-specific tools may simplify the evaluation process by focusing on unique exposures. The final Physical Job Evaluation Checklist is currently presented in the form of a spreadsheet available for download and use ( www.lni.wa.gov/Safety/Research/Wmsd/WMSD2010.asp ). Accompanying reference guide is also available to provide instructions how data fields can be obtained or measured. The user can print out a paper form first, record the assessment at a job site, then enter the necessary data into the spreadsheet. The algorithm then generates all the evaluation reports and highlight areas that should receive attention. The goals are to raise general awareness of industry-specific physical factors that contribute to work-related musculoskeletal disorders (WMSDs), and help identify specific aspects of the job that pose a risk for back, shoulder, hand/wrist and knee injury common in the construction industry. Using the Physical Job Evaluation Checklists can help prioritize injury prevention efforts by identifying the jobs, or the aspects of the job that pose the greatest risk of injury. It is also possible to evaluate the impact that proposed jobsite changes have on WMSD risk (before and after exposures). And finally, it is possible to compare exposures between workers performing the same or different tasks. Limitation Due to the study design, the Physical Job Evaluation Checklist IS NOT intended to predict the occurrence of WMSDs or to provide guidance or suggestions on how to mitigate exposure to risk factors of WMSDs.

Ergonomic Analysis

Two groups of movement retrained computer users with prior computer-related upper extremity musculoskeletal disorders underwent qualitative orthogonal video motion analysis. Ergonomic analysis of subjects' computer use habits suggests that movement retraining may decrease risk factors for work related musculoskeletal disorders and therefore warrants further study.

Abstract Background: Musculoskeletal disorders can result from prolonged repetitive and/or forceful movements. Performance of an upper extremity high repetition high force task increases serum pro-inflammatory cytokines and upper extremity sensorimotor declines in a rat model of work-related musculoskeletal disorders. Since one of the most efficacious treatments for musculoskeletal pain is exercise, this study investigated the effectiveness of treadmill running in preventing these responses. Methods: Twenty-nine young adult female Sprague-Dawley rats were used. Nineteen were trained for 5 weeks to pull a lever bar at high force (15 min/day). Thirteen went on to perform a high repetition high force reaching and lever-pulling task for 10 weeks (10-wk HRHF; 2 hrs/day, 3 days/wk). From this group, five were randomly selected to undergo forced treadmill running exercise (TM) during the last 6 weeks of task performance (10-wk HRHF+TM, 1 hr/day, 5 days/wk). Results were compared to 10 control rats and 6 rats that underwent 6 weeks of treadmill running following training only (TR-then-TM). Voluntary task and reflexive sensorimotor behavioral outcomes were assessed. Serum was assayed for inflammatory cytokines and corticosterone, reach limb median nerves for CD68+ macrophages and extraneural thickening, and reach limb flexor digitorum muscles and tendons for pathological changes. Results: 10-wk HRHF rats had higher serum levels of IL-1α, IL-1β and TNFα, than control rats. In the 10-wk HRHF+TM group, IL-1β and TNFα were lower, whereas IL-10 and corticosterone were higher, compared to 10-wk HRHF only rats. Unexpectedly, several voluntary task performance outcomes (grasp force, reach success, and participation) worsened in rats that underwent treadmill running, compared to untreated 10-wk HRHF rats. Examination of forelimb tissues revealed lower cellularity within the flexor digitorum epitendon but higher numbers of CD68+ macrophages within and extraneural fibrosis around median nerves in 10-wk HRHF+TM than 10-wk HRHF rats. Conclusions: Treadmill running was associated with lower systemic inflammation and moderate tendinosis, yet higher median nerve inflammation/fibrosis and worse task performance and sensorimotor behaviors. Continued loading of the injured tissues in addition to stress-related factors associated with forced running/exercise likely contributed to our findings.
