Musculoskeletal disorders are one of the major health hazards among farmers. Pre-adolescents are mainly associated with agricultural work due to poor socioeconomic conditions.
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.
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.
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.
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.
肌肉骨骼疾病是农民面临的主要健康危害之一。由于较差的社会经济条件，未成年前儿童主要与农业劳动有关。
本研究旨在引入新的人体工程学辅助工具，以改善工作程序，提高未成年前农民的生产力、健康和安全。
从印度西孟加拉邦塔拉克什瓦尔的村庄中随机选择了 100 名男性和 100 名女性未成年前农民，以评估和减少与工作相关的肌肉骨骼疾病和生理压力。在使用人体工程学辅助工具之前和之后，评估了改良北欧问卷、身体部位不适（BPD）量表和握力。
研究结果表明，使用新设计的人体工程学辅助工具后，未成年前农民的下背部、手腕、肩部和手部的不适感显著降低。在工作后条件下，未成年前农民的握力增加，生理压力降低。使用人体工程学辅助工具可减少旷工，从而提高农业生产效率。
本研究表明，使用人体工程学辅助工具可以减少旷工，从而提高农业生产效率，同时显著降低不适感。
