Background: Musculoskeletal disorders are one of the major health hazards among farmers. Pre-adolescents are mainly associated with agricultural work due to poor socioeconomic conditions.
Objectives: This study aims to implement a new ergonomics aid for the betterment of job procedures and improvement of productivity, health, and safety of the preadolescent farmers.
Methods: 100 male and 100 female preadolescent farmers were randomly selected from the villages of Tarakeswar, West Bengal, India, to evaluate and reduce work-related musculoskeletal disorders, physiological stress. Modified Nordic questionnaires, Body Part Discomfort (BPD) scale, and handgrip strength were assessed before and after using the ergonomics aid.
Results: The results of the study show that there was a significant change (decrease) in discomfort in the lower back, wrists, shoulder, and hands among preadolescent farmers when using the newly designed ergonomic aid. Handgrip strength increased and physiological stress was decreased among preadolescent farmers in post-intervention than pre-intervention in just after work conditions. Productivity has been increased in farming by decreasing absenteeism from work with the use of ergonomic aid.
Conclusion: This study concludes that productivity has been increased in farming by decreasing absenteeism from work as well as by using the ergonomic aid the discomfort feeling has been decreased markedly.
