Manual harvesting is a physically demanding occupation with several work-related issues in which musculoskeletal disorders (MSDs) happen most commonly. The risk factors for MSDs among manual harvesting farmers are not investigated properly in low and low-middle-income nations. Therefore, a study among 140 farmers of Rajasthan, India was carried out through the usage of Nordic Musculoskeletal Questionnaire and the Rapid Upper Limb Assessment (RULA) technique to identify ergonomic risks. χ2 analysis was used to find the relationship between the MSDs and various factors. Also, logistic regression methodology was applied to get the most influencing factor for MSDs in different body regions. The lower-back, fingers, shoulders and wrists/hands were the body parts in which more than 50% workers reported MSDs. MSDs in one or more body regions were found to be associated with age, daily working in farms, farming experience, gender, hand dominance and perceived work fatigue. The age was majorly associated with MSDs in all body regions except the shoulder and neck as per the outcome of logistic regression. The outcome of RULA grand score had been found higher than or equal to 5 in 92% of the farmers which give directions for further research and changes.

The present study is aimed to investigate the musculoskeletal issues and association of risk-factors with these problems among manual brick kiln workers. A modified Nordic Questionnaire was administered among 376 traditional brick kiln workers to collect data. Logistic regression was used to determine the association between musculoskeletal problems and risk-factors. Majority of workers (76.19%) involved in mould evacuating task reported wrist issues whereas lower back issues were reported by 62.35% of spading task workers. Age was a factor associated with musculoskeletal symptoms in the majority of the body regions. Gender was significantly associated with lower back (OR=3.71, CI: 1.51-9.11) MSDs. Spading task was associated with the wrist (OR=2.42, CI: 51.03-5.66), and lower back (OR=3.97, CI: 1.75-8.98) problems. Mould filling was a contributing factor for the wrist (OR=4.27, CI: 1.81-10.09) and knee (OR=6.88, CI: 2.40-19.70) issues. MSDs in wrist (OR=12.22, CI: 4.82-30.98) and fingers (OR=3.57, CI: 1.23-10.36) were significant in mould evacuating workers. Workers having less than 5 yr of experience were less prone to the neck (OR= 0.03, CI: 0.00-0.72) and upper back (OR=0.08, CI: 0.01-0.76) MSDs. For prevention of problems, ergonomic interventions such as workers' training, use of protecting aids, modification in hand tools and work practices are needed.
