Factors affecting the perception of whole-body vibration of occupational drivers: an analysis of posture and manual materials handling and musculoskeletal disorders

Abstract

Due to the high cost of conducting field measurements, questionnaires are usually preferred for the assessment of physical workloads and musculoskeletal disorders (MSDs). This study compares the physical workloads of whole-body vibration (WBV) and awkward postures by direct field measurements and self-reported data of 45 occupational drivers. Manual materials handling (MMH) and MSDs were also investigated to analyse their effect on drivers' perception. Although the measured values for WBV exposure were very similarly distributed among the drivers, the subjects' perception differed significantly. Concerning posture, subjects seemed to estimate much better when the difference in exposure was significantly large. The percentage of measured awkward trunk and head inclination were significantly higher for WBV-overestimating subjects than non-overestimators; 77 and 80% vs. 36 and 33%. Health complaints in terms of thoracic spine, cervical spine and shoulder–arm were also significantly more reported by WBV-overestimating subjects (42, 67, 50% vs. 0, 25, 13%, respectively). Although more MMH was reported by WBV-overestimating subjects, there was no statistical significance in this study.

Combined exposures of whole-body vibration and awkward posture: a cross sectional investigation among occupational drivers by means of simultaneous field measurements

“…This system permits the quantitative analysis of posture as body angles during exposure to WBV. Thus, the measurements provide an objective and quantitative description of such exposures (Raffler et al 2016). However, its relationship to adverse health effect is still unknown.…”

Ergonomic Assessment Tool for Real-Time Risk Assessment of Seated Work Postures

“…Work postures, if awkward, can lead to WMSDs among workers on the shop floor [12]; [13]. Measuring posture movements has been found to be very important for determining the risk of WMSDs in the workplace [14] and the methods for assessing these risks depends on the accuracy and precision of the data collection techniques employed [15].…”
