The apparent density ρ may be described as a relationship with the number of years of exposure of drivers, e.g., for an old driver (65 years old) ρ = ~0.18 g/cm 3 . Considering the ISO 2631-5:2004 limits, it appears that the equivalent IRF threshold for a 65-year-old driver is 30-50%.…”

“…Several bibliographical reviews have indeed been published over the past 15 years; they show a higher occurrence of low back pain among populations exposed to dynamic loading, such as heavy-equipment drivers, than in the general population [2]. Available epidemiologic data are not, however, generally sufficiently powerful to establish a dose-effect relationship between exposure to WBV and the risk of lumbar disorders [3]. In fact, WBV induce dynamic stresses, principally compressive, into the spine, producing microfractures into the endplates and vertebral body.…”

Occupational exposure to whole‐body vibration is associated with the development of musculoskeletal, neurological, and other ailments. Low back pain and other spine disorders are prevalent among those exposed to whole‐body vibration in occupational and military settings. Although standards for limiting exposure to whole‐body vibration have been in place for decades, there is a lack of understanding of whole‐body vibration‐associated risks among safety and healthcare professionals. Consequently, disorders associated with whole‐body vibration exposure remain prevalent in the workforce and military. The relationship between whole‐body vibration and low back pain in humans has been established largely through cohort studies, for which vibration inputs that lead to symptoms are rarely, if ever, quantified. This gap in knowledge highlights the need for the development of relevant in vivo, ex vivo, and in vitro models to study such pathologies. The parameters of vibrational stimuli (eg, frequency and direction) play critical roles in such pathologies, but the specific cause‐and‐effect relationships between whole‐body vibration and spinal pathologies remain mostly unknown. This paper provides a summary of whole‐body vibration parameters; reviews in vivo, ex vivo, and in vitro models for spinal pathologies resulting from whole‐body vibration; and offers suggestions to address the gaps in translating injury biomechanics data to inform clinical practice.

Most studies on the occupational hazards associated with forklift operation have examined risks of fatalities and traumatic injuries. Few studies have examined the magnitude of risk of lower back pain. This research deals with an evidence-based approach designed to examine if there is a relationship between whole-body vibration and driver postures with lower back pain among forklift operators and to offer some recommendations to minimize the risk of lower back pain. To accomplish the study goal, an evidence-based approach was adopted from evidence-based medicine. The basic steps of this evidence-based approach were: (1) formulation of a clear research question from a workeroccupational problem; (2) search of the literature for the best evidence with which to answer the question; (3) critically appraise the evidence; and (4) implement useful findings in occupational health and safety practices. In addition, the metarelative risk was calculated and the biological plausibility between whole body vibration (WBV) and operator posture with lower back pain was investigated. Six observational articles satisfied the inclusion criteria adopted in this research. The methodological qualities of the published studies ranged from marginal to average. The metarelative risk was 2.1, indicating that operators exposed to driving forklifts are greater than twice the risk of those not exposed to driving forklifts to experience lower back pain. There are biological mechanisms by which WBV and operator postures could develop lower back pain. Some aspects of the work environment that influenced vibration are seat, speed, track, and tires. Awkward postures and static postures are affected by cab design, seat, time spent seated, and the task performed. It appears that there is a causal relationship between forklift operation and lower back pain. The evidence examined shows a strong association and consistency between all studies and this relationship is biologically plausible. It is recommended that intervention studies be conducted to determine the effectiveness of ergonomic controls. C 2008 Wiley Periodicals, Inc.
