Falls from non-moving vehicles constitute a significant portion of fall related fatal occupational injuries, with a yearly average of 48.7 fatal falls, from 1992 to 2002. Whole-body vibration (WBV) has been thought to be a contributing factor to loss of balance, more specifically, falls while descending from a vehicle. The current research employed a “real-time” actual trucking environment, rather than vibration platforms in laboratories, as is typically the case. Nine (9) full-time, long haul truck drivers' drove over 3000 miles in total, while participating in this study. The protocol required postural stability testing prior to, and immediately following, each of three driving sessions of 2.5 hours during a single shift. Results indicate significant changes in postural stability as a result of exposure to extended durations of WBV. The results also showed an increase of sway (cm) at each of the post-test measures compared to the pre-test, and an overall increase over the 8.5 hour shift, suggesting a time dependent increase over the course of the driving shift.

SYNOPSIS Whole-body vibration (WBV) exposure measurements taken from 105 truck drivers employed in 19 mines and other workplaces were evaluated with the criteria prescribed in EU 2002/44/EC directive, BS 6841 (1987), ISO 2631-1 (1997). and ISO 2631-5 (2004) standards. The highest vibration acceleration was measured on the vertical Z-axis. The highest WBV exposure occurred in the RETURN, HAUL, and SPOT phases while the lowest exposure took place in the LOAD and WAIT phases. Crest factors on all axes were generally greater than nine, yet strong correlation coefficients were achieved in VDV-eVDV analyses. Driver seats generally dampened the vibration along the Z-axis but exacerbated it along X and Y axes. The dominant frequency for the X and Y-axes rose up to 40 Hz while it ranged between 1 Hz and 2.5 Hz along the Z-axis. While the probability of an adverse health effect was higher with BS 6841 (1987) and ISO 2631-1 (1997) standards, it was low according to EU 2002/44/EC and ISO 2631-5 (2004). The 91 t, 100 t, and 170 t capacity trucks produced lower vibration magnitudes. Drivers were exposed to approximately equivalent levels of WBV acceleration and dose in contractor-type trucks and mining trucks. Rear-dump trucks exposed their drivers to a slightly higher level of vibration than bottom-dump trucks. Underground trucks exposed their drivers to a significantly higher level of vibration than mining trucks. Both driver age and driver experience were inversely proportional to vibration acceleration and dose. Conversely, there was a positive relationship between the truck service years and the WBV acceleration and dose to which drivers were exposed to. Loads of blocky material exposed drivers to higher vibration acceleration and dose levels than non-blocky material.

Daily Exposure

Exposure to whole body vibration (WBV) is known to be associated with various adverse health outcomes among professional truck drivers. As a part of a randomized controlled trial, this study evaluated WBV exposures and various health outcomes from 96 professional truck drivers. The WBV was measured and analyzed per International Standards Organization (ISO) 2631-1 and 2631-5 WBV standards. This study also measured self-reported regional body pain (10-point scale), low back disability (the Oswestry Disability Index), and physical/mental health (the Short Form 12-item Health Survey). Lastly, this study evaluated associations between the WBV exposure and various health outcomes. The results showed that the predominant z-axis weighted average vibration [A(8)] measure (Mean ± SE: 0.35 ± 0.01 m/s2) was below the ISO and European Union (EU) daily exposure action limits (0.5 m/s2) whereas the vibration dose value [VDV(8)] measure (12.2 ± 0.3 m/s1.75) was above the ISO and EU daily exposure action limit (9.1 m/s1.75). Self-reported low back pain (LBP) was the most prevalent adverse musculoskeletal outcome reported (72.5%) with average LBP score of 2.9 (SD: 2.0). The SF-12 health scores showed that truck drivers’ physical health status was lower than the average US population (p’s < 0.04). Moreover, the Spearman’s correlations ( rs ) between the WBV parameters and health outcomes indicated that A(8) measures were associated with LBP ( rs = 0.31; r = 0.05) and SF-12 physical composite score ( rs = −0.39; r = 0.02); however VDV(8) was not associated with any of the health outcomes. The study findings indicates that although the impulsive exposures [VDV(8)] were more prominent, the continuous, average vibration [A(8)] appears to be more strongly associated with injury risks. This finding supports the practice of EU countries using A(8) as one of the primary measures for characterizing daily WBV exposures but also complements many other studies indicating that the current EU daily action limit value of 0.50 m/s2 for WBV may be too high.

The Mean

Context: Chronic ankle instability (CAI) is a common problem associated with impaired postural stability. Whole-body vibration (WBV) has been developed to improve muscle function and reportedly improves postural stability. The aim of this study was to evaluate the effect of 12 sessions of WBV on postural control during standing postural task in participants with CAI. Design: A controlled clinical trial study. Methods: Sixteen participants with CAI and 16 healthy participants aged between 20 and 40 years included in this study. They received WBV (30-Hz frequency, 3 series of four 45-s exercises with a 45-s rest) for a total of 12 sessions, 2 session per week for 6 weeks. Postural control was assessed by center of pressure (COP) parameters, including mean and SD in the anterior–posterior and medial–lateral displacement during single-leg standing. Assessments were done before and immediately after the first session and after the 12th session of WBV, with opened and closed eyes associated with easy and difficult cognitive tasks. Results: The results showed that the SD of COP displacement in the x-axis was significant in eyes opened and SD of COP displacement in the x- and y-axes were significant between groups in the eyes-opened, and eyes-closed conditions (P < .05). Analysis of variance indicated that the effect of WBV training was significant for the mean of COP displacement in the y-axis. Post hoc indicated that the effect of 12 sessions of WBV on the mean of COP displacement was significant in the CAI group (P < .05). However, the acute effect of WBV was not significant on the COP displacement in all axes (P > .05). Conclusion: Higher postural sway associated with postural cognitive interactions might be considered in the rehabilitation of CAI. Twelve sessions of WBV might induce some improvement in postural control with the method of WBV used in this study.
