Factors Associated with Musculoskeletal Disorders Among Tractor-Operating Farmers in a Subdistrict of Roi Et Province, Thailand: A Cross-Sectional Study.

In conclusion, tractor-driving characteristics, duration of tractor use, Subjective Workload Index, and postural ergonomics were associated with musculoskeletal disorders in this tractor-operating farmer group.

Perceived vibration exposure may be an important factor associated with musculoskeletal disorders, suggesting that engine speed management and ergonomic improvement may be considered as potential occupational health strategies for tractor-operating farmers.
