摘要：Exposure to vibration is the cause of some occupational injuries and diseases. Objective of this study was determination of vibration exposure of tractor drivers and assessment of musculoskeletal disorder . This cross-sectional and descriptive- analytical study was administrated to 95 tractor drivers to census method and measuring induced vibration to the drivers was done in three axis, x, y, and z in tractors with load (10000 liter water), without load, with 10 km/h speed, by the vibration meter instrument “Sevantek”. The information related to musculoskeletal disorder was collected by using Nordic questionnaire. Data from both parts was analyzed by using SPSS. In the over load tractor group and with velocity vibration 10km/h, 50% of workers were in the range of reduced comfort boundary, 39.3% in the range of fatigue decreased proficiency boundary and 10.7% in over exposure limit. This results were in the without load tractor group and with the same velocity, 23.8% of people were in the range of reduced comfort boundary, 42.9% in the range of fatigue decreased proficiency boundary and 33.3% in the range of over exposure limit and waist with 56.8% had the greatest rate of pain and ankle with 9.5% had the least amount of pain rate. Using of many tractors in city to displace water and other applications, paying attention to the health of drivers and checking the periodically, is needed.
