Background and aims: Whole Body Vibration (WBV) transmitted to drivers is one of the main reasons for several different symptoms such as musculoskeletal disorders. One of the recommendations to decrease the effects of whole body vibration is using a device that acts as an isolator. In this study, we used an air cushion as a device to decrease WBV. We measured whole body vibration transmitted to drivers before and after using this air cushion. Methods: This interventional study was performed with 95 bus drivers in Isfahan. Vibration parameters were measured in 3 axes and amount, of vibration were measured before and after using air cushion. Statistical analysis the data was carried out using the SPSS software, in which data were analyzed using the students paired t test. Results: Comparison of the vibration before and after using the air cushion showed a significant reduction in maximum pressure (Pmax) in X and Y axes (P<0.05), a significant reduction in acceleration equivalent value (Aeq) in X and Y axes (P<0.001). Finally, Lmax was decreased in X axis. Conclusion: Our data showed that the buses which are being used in Isfahan vibrate more than the standard level. Although, using air cushion could significantly reduce vibration transmitted to bus drivers, but the vibration is still over than standard level.
