“…The vibration suffered by workers when operating with vehicles depend on, among others, the external excitation force, the mass of the vehicle and environmental factors such as the condition of the pavement, the characteristics of the material handled, operations organization and worker experience (Mandal & Srivastava 2010;Frimpong, Galecki et al 2011). As expected, exposure to WBV does not depend on the type of operation (raw material), but from the working conditions and the type of equipment used as stated by the authors as Vanerkar, Kulkarni et al (2008).…”

“…The vibration transmitted through the feet and the seat backrest is not normally considered (Leduc, Eger et al 2011). Other parameters analyzed in WBV studies are: machines characteristics (Kumar 2004;Howard, Sesek et al 2009;Eger, Stevenson et al 2011;Dentoni & Massacci 2013); operations that the equipment performs (Kumar 2004;Eger, Stevenson et al 2008;Salmoni, Cann et al 2010;Smets, Eger et al 2010;Leduc, Eger et al 2011); work routines (Torma-Krajewski, Wiehagen et al 2009;Smets, Eger et al 2010); pavement conditions (Mayton, Amirouche et al 2005;Howard, Sesek et al 2009;Salmoni, Cann et al 2010;Dentoni & Massacci 2013); position and seat features (Mayton, Amirouche et al 2005); vibration type (continuous, intermittent, impact) and its direction and source (Leduc, Eger et al 2011); number of times that performs the task or all work cycle per day, average duration of the task or work cycle (Mandal & Srivastava 2010;Smets, Eger et al 2010); Simultaneously, other important information are collected as e.g. demographic information, medical and occupational historic and lifestyle (Eger, Stevenson et al 2008;Mandal & Srivastava 2010;Smets, Eger et al 2010;Eger, Stevenson et al 2011;Leduc, Eger et al 2011).…”

“…Operators of vehicles used in mining operations are exposed to considerable WBV during relatively long work periods [10][11][12][13][14][15]. Studies have also shown that the prevalence of self-reported musculoskeletal symptoms is higher among drivers of mine vehicles than among nonexposed workers [16,17]. In recent years it has become more common for females to be employed in the mining industry.…”

Objectives: This cross-sectional questionnaire study was carried out at 4 open-pit mines in Finland, Norway, Russia and Sweden as part of the MineHealth project. The aim has been to compare the prevalence of musculoskeletal symptoms between drivers of mining vehicles and non-drivers. Material and Methods: The mine workers were asked whether they had suffered from any musculoskeletal symptoms during the previous 12 months in specified body regions, and to grade the severity of these symptoms during the past month. They were also asked about their daily driving of mining vehicles. Results: The questionnaire was completed by 1323 workers (757 vehicle drivers) and the reported prevalence and severity of symptoms were highest for the lower back, followed by pain in the neck, shoulder and upper back. Drivers in the Nordic mines reported fewer symptoms than non-drivers, while for Russian mine workers the results were the opposite of that. The daily driving of mining vehicles had no significant association with the risk of symptoms. Female drivers indicated a higher prevalence of symptoms as compared to male drivers. Conclusions: The study provided only weak support for the hypothesis that drivers of vehicles reported a higher prevalence of musculoskeletal symptoms than non-vehicle drivers. There were marked differences in the prevalence of symptoms among workers in various enterprises, even though the nature of the job tasks was similar.

Background: Low back pain (LBP) and degenerative changes in the spinal system are reportedly associated with exposure to low frequency (0.5- 80 Hz) whole-body vibration (WBV). The main objective of the study was to determine prevalence of musculoskeletal disorders among Heavy Earth Moving Machinery (HEMM) operators exposed to WBV in an opencast mine in western India.Methods: Forty six operators from an opencast mine were recruited as exposed group in a questionnaire based cross-sectional study. Twenty eight employees engaged in sedentary office work were taken as control. All subjects were asked about location and severity of body pain in the past 7 days and 12 months. A four point pain scale was used. Significance of difference of demographic / anthropometric parameters was studied using t-test of independent samples. Association between the pain type and exposure was obtained using Chi-square test. Risk of each type of pain was determined in terms of odds ratio. Adjusted estimate of ORs were obtained through logistic regression modelling, wherein the model fitness was judged using Hosmer-Lemeshow test.Results: The mean exposure duration was 11.30 ± 7.45 years. LBP was the most predominant MSD which showed highly significant association with exposure (P <0.001). Overall, the risk analysis revealed a significant increase in the likelihood of MSD due to exposure. 39% of the exposed group required medical attention.Conclusions: Based on subjective response of exposed group, it can be said that prevalence of musculoskeletal pain as manifestation of MSD due to exposure to WBV especially LBP is high among HEMM operators which affected their quality of life.
