Results of study show that experience workers having more reported pain in upper body parts due to poor work station design. This study is focused on measuring the Risks for WMSDs (Work related musculoskeletal disorders) among workers in a manufacturing company, by applying ergonomic tools like QEC (quick exposure checklist), RULA (rapid upper limb assessment) scores and Nordic questionnaire. A cross-sectional study was conducted among workers aged between 18 to 45 years with a total number of 48 workers selected through random sampling with in the duration of 12 weeks. Validated version of QEC, RULA score sheet and Nordic questionnaire was used to measure the risk level and number of reported pain in body parts among workers. The results showed that the mean score of QEC and RULA was 73.6 and 4.6 respectively. However, results showed that experienced workers reported more pain in different body parts, indicating more chances of WMSDs among them. 79% workers of total sample had reported pain in different parts of body according to Nordic questionnaire, out of which 86% workers had pain in upper part and 14% had pain in lower part of the body that was also verified from QEC and RULA score sheet.

overnight rest. These types of jobs are often those involving activities such as repetitive and forceful exertions; frequent, heavy, or overhead lifts; awkward work positions; or use of vibrating equipment. [1] One of the most prevalent types of work-related injuries is musculoskeletal disorders. Work-related musculoskeletal disorders (WRMDs) result in persistent pain, loss of functional capacity, and work disability, but their initial diagnosis is difficult because they are mainly based on complaints of pain and other symptoms. [2] Therefore, further studies are needed to analyze the association between subjective descriptions and objective findings. [3] The traumatic injuries of the muscles, tendons, and nerves due to accidents are not considered to be WRMDs or are considered separately. Work activities which are Background: Work-related musculoskeletal disorders (WRMDs) are a group of painful disorders of muscles, tendons, and nerves. Carpal tunnel syndrome, tendonitis, thoracic outlet syndrome, and tension neck syndrome are examples. Fascination with technology, overly ambitious business expectation, and neglected human factor risks can have serious effects on manufacturers, suppliers, and service enterprises. As India is one of the largest and growing hubs in the world of manufacture industry, there is a great need to identify such problem. In this study, we identified such problems and discussed it. Objectives: The aim of this study is to gather data to identify jobs or work conditions that are most problematic, using sources such as injury and illness logs, medical records, and job analyses. Materials and Methods: Data collection was done by personal interview, history and physical examinations, specific symptoms questionnaire, and rapid upper limb assessment (RULA) survey for WRMDs. Results: In our study, we found that prevalence of neck pain was highest followed by back pain in general. Most participants had complained that pain only aggravated when they continue work without taking rest. On examination, the presence of cervical spine tenderness was highest, followed by hand joints and lumbar spine tenderness. In admin and skilled participants, RULA score was up to 4 (satisfactory and modification required), but in unskilled participants, RULA was up to 7 (not satisfactory and immediate changes may require). Conclusion: Work activities which are frequent and repetitive or activities with awkward postures cause these disorders which may be painful during work or at rest. Most WRMD affects the hands, wrists, elbows, neck, and shoulders.
The aim of the present study was to analyze the association between the activity performed in the workplace and symptoms of musculoskeletal disorders (MSD) in different body regions. We evaluated 146 employees, divided into two sectors: sector I (n=61), cleaning and building maintenance, and sector II (n=85), administrative sector. The employees answered the census of the ergonomics questionnaire that assesses MSD reported in different body regions. In sector I, 39.6% (n=19) of the employees had symptoms in the lower limbs, with an association between activity performed and body region reported (p=0.025). In sector II, 51.7% (n=31) of the employees had symptoms in the neck and 26.7% (n=16) in the wrist, with an association between activity performed and body region reported (p=0.001 and p<0.002, respectively). The results showed that employees had MSD symptoms associated with the activity performed, indicating the need to develop specific interventions for each kind of workplace....
Musculoskeletal disorders may be observed in all industries and professions and most of these disorders are related to the back, upper and lower extremities of the body organs. In Pharmaceutical industry, almost lack of standard ergonomic conditions and sometimes can cause outbreaks of diseases and musculoskeletal disorders in various parts of the body. The aim of this study was to determine the relationship between musculoskeletal disorders and working on the packaging section of the pharmaceutical industry. The Nordic questionnaire and Rula method were used for collection of data and 392 workers were selected as the subjects of study. Based on the results of this study, (28.5%) of workers working in Packaging Unit complained of severe pain and discomfort in their neck, (23.7%) in their shoulder, (27.9%) in their hand and wrist and (33.2%) complained of severe pain in their back.

Objective Over the course of the twenty-first century, work-related musculoskeletal disorders are still persisting among blue collar workers. At present, no epidemiological overview exists. Therefore, a systematic review and meta-analysis was performed on the epidemiology of work-related musculoskeletal disorders (WMSD) within Europe’s secondary industries. Methods Five databases were screened, yielding 34 studies for the qualitative analysis and 17 for the quantitative analysis. Twelve subgroups of WMSDs were obtained for the meta-analysis by means of predefined inclusion criteria: back (overall), upper back, lower back, neck, shoulder, neck/shoulder, elbow, wrist/hand, leg (overall), hip, knee, and ankle/feet. Results The most prevalent WMSDs were located at the back (overall), shoulder/neck, neck, shoulder, lower back and wrist WMSDs with mean 12-month prevalence values of 60, 54, 51, 50, 47, and 42%, respectively. The food industry was in the majority of subgroups the most promi...

Background: Work-related musculoskeletal disorders are present in a range of occupations. This is confirmed from a number of studies done around the world. However, few attempts have been done to document the presence of musculoskeletal disorders in occupational diseases in Nepal and there are hardly any studies done to see musculoskeletal disorders in farmers of Nepal. Nepal is an agricultural country and traditional practices in farming are adopted demanding a lot on the manual work. Objectives: Aim of this study is to find out the prevalence of musculoskeletal disorders in Bhaktapur district of Nepal. Methods: This is a descriptive cross-sectional study design. A convenience sample of 246 farmers from Bhaktapur district, Nepal aged between 24-65 years, were included in the study. The Nordic musculoskeletal questionnaire was a tool adapted to measure MSDs in the farmers. Descriptive analysis of data was done. Results: Farmers (n=246) reported pain in all the nine areas of the body mentioned in the questionnaire. More than 70% of farmers have some kind of musculoskeletal disorders. However, six major areas of pain were identified as: Neck-31(12.6 %), Shoulder-26(10.6%), Elbow-30(12.2%), Low back-89(36.2%), Knee-53(21.5%) and ankle 32(13%). Conclusion: The prevalence of musculoskeletal disorders in farmers is very high. Lack of awareness about the MSDs and improper knowledge of ergonomics causes the problems.

Musculoskeletal disorders among workers in plastic manufacturing plants
Revista Brasileira de …, 2010
BACKGROUND: Epidemiological studies have indicated an association between musculoskeletal disorders (MSDs) and physical work demands. Psychosocial work demands have also been identified as possible risk factors, but findings have been inconsistent. OBJECTIVES: To evaluate factors associated with upper back, neck and upper limb MSD among workers from 14 plastic manufacturing companies located in the city of Salvador, Brazil. METHODS: A cross-sectional study design was used to survey a stratified proportional random sample of 577 workers. Data were collected by questionnaire interviews. Factor analysis was carried out on 11 physical demands variables. Psychosocial work demands were measured by demand, control and social support questions. The role of socio-demographic factors, lifestyle and household tasks was also examined. Multiple logistic regression was used to identify factors related to upper back, neck and upper limb MSDs. RESULTS: Results from multiple logistic regression showed that distal upper limb MSDs were related to manual handling, work repetitiveness, psychosocial demands, job dissatisfaction, and gender. Neck, shoulder or upper back MSDs were related to manual handling, work repetitiveness, psychosocial demands, job dissatisfaction, and physical unfitness. CONCLUSIONS: Reducing the prevalence of musculoskeletal disorders requires: improving the work environment, reducing biomechanical risk factors, and replanning work organization. Programs must also be aware of gender specificities related to MSDs.
