“…Similar works also report discrepancies in balance and postural sway outcomes following WBV exposure, with certain studies reporting decrements in postural sway after WBV exposure [ 4 , 22 , 49 ] and others reporting no [ 50 ] or minimal decrements [ 20 ] in postural sway outcomes after WBV exposure. In these cases where balance decrements after WBV exposure were reported, several elements which were not present in the current study may be related to disturbances in balance and postural sway outcomes.…”

“…For example, Park et al. [ 49 ] exposed participants to two 2-hour sessions with a 30-minute break in between, having the participants remain seated for a total of 4.5 h, and report decrements in postural sway mean velocity. Other studies reporting decrements in postural sway outcomes either had participants stand during WBV exposure [ 4 ], or were evaluating balance after WBV exposure from a quad bike [ 20 , 22 ] where participants are required to undertake an active riding stance [ 51 ], which involves the rider changing their body position and the centre of gravity to optimize stability.…”

Background & Objective : Negative health effects from occupational whole-body vibration (WBV) exposure during machinery operation include alterations in proprioception, vestibular function, reaction time, stress, motor response, and decrements in musculoskeletal health. To reduce WBV exposure during machinery operation, it may be possible to incorporate short rest break activities throughout the day. This study aims to determine if there are intervention activities that can minimize decrements in cognitive, proprioceptive, and musculoskeletal effects related to WBV exposure during machine operation. Materials & Methods Eleven healthy adults participated in four 1-hour sessions of ecologically valid WBV exposure followed by one of four 5-minute activities: sitting, walking, 2 min of gaze stabilization exercise (GSE) coupled with 3 min of trunk mobility exercise (GSE + MOBIL), or 2 min of GSE coupled with a 3-minute walk (GSE + WALK). Baseline and post-activity measurements (rating of perceived discomfort, balance and postural sway measurements, 5-minute psychomotor vigilance task test) were submitted to a paired t-test to determine the effect of WBV exposure and activities on physical, cognitive, and sensorimotor systems and to a repeated measures ANOVA to determine any differences across activities. Results We observed degradation of the slowest 10% reaction speed outcomes between baseline and post-activity after walking (7.3%, p < 0.05) and sitting (8.6%, p < 0.05) but not after GSE + MOBIL or GSE + WALK activities. Slowest 10% reaction speed after GSE + MOBIL activity was faster than all other activities. The rating of perceived discomfort was higher after SIT and WALK activities. There were no notable differences in balance outcomes. Conclusion When compared to sitting for 5 min, an activity including GSE and an active component, such as walking or trunk mobility exercises, resulted in maintenance of reaction time after WBV exposure. If confirmed in occupational environments, GSE may provide a simple, rapid, effective, and inexpensive means to protect against decrements in reaction time after WBV exposure.

Whole-body vibration (WBV) is a recognized health hazard that primarily affects the musculoskeletal system of human beings. Although research works on WBV are documented, for the past few decades or so, researchers are still attempting to explore the role of contributing factors of WBV for the causation of musculoskeletal disorders (MSDs). Therefore, this paper synthesizes up-to-date knowledge on WBV with respect to measurement methods, critical vibration magnitudes, contributing factors, and effects on human health. The present review is based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) that includes 112 studies on WBV exposure and its contributing factors. It also summarizes the contributing factors of MSDs that include personal factors, environmental factors, machine-related factors, and WBV exposure of the heavy vehicles and equipment operators across various industries. Most of the studies reported lower back pain as the most common MSDs experienced by the vehicle operators exposed to WBV, followed by upper back pain. However, it is apparent from the prevailing literature that musculoskeletal health risks do not result from exposure to WBV alone. The role of multivariate contributing factors should also be considered, analyzed, assessed, and understood to establish correlations between these factors with the development of MSDs. In addition to the measurement and assessment of WBV as per the ISO guidelines to evaluate the potential and likely health risks faced by the heavy equipment operators, researchers should also focus on studying various impacts of WBV, and understanding the role of its contributing factors on human health using advanced machine learning tools.

“…Outcome measures for the sit-to-stand transition task included reaction time, initiation to counter time, initiation to peak time, and sit-to-stand time as well as initiation to peak amplitude (Kera et al, 2022). For upright static standing task, center of pressure (COP)-based postural sway parameters were obtained for outcome measures (Park et al, 2021), including COP mean velocity and sample entropy in the medial-lateral (ML) and anteroposterior (AP) directions.…”

“…Off-road vehicle operators in agriculture, construction, and mining are especially at high risk as their exposure to WBV is not limited to the vertical (Z) axis, but also contains significant fore-aft (X) and lateral (Y) components due to rough terrains (Kim et al, 2018). Previous studies have shown that postural stability can be impaired by vertical-dominant WBV (which on-road vehicle operators are often exposed to) as well as multi-axial WBV (e.g., Park et al, 2021). However, the relative impacts of multi-axial WBV on postural stability compared to vertical-dominant WBV, particularly during vehicle egress, are not well understood.…”

This repeated-measures laboratory study characterized the relative impacts of vertical-axial dominant and multi-axial Whole-Body Vibration (WBV) exposures on postural stability. Eleven healthy participants were exposed to field-measured vibration profiles collected from on-road commercial (vertical-dominant WBV) and off-road mining vehicles (multi-axial WBV) for four hours on two different days. Before and after the exposure, postural stability was evaluated while participants performed sit-to-stand tasks followed by static standing tasks. Overall, the study results indicate that off-road, multi-axial WBV may compromise postural stability more so than on-road, vertical-dominant WBV. These findings may suggest that off-road vehicle operators are at a greater risk of fall-related injuries. Therefore, there is a critical need to develop more effective vibration control measures among off-road vehicle operators.
