“…Second, although participants' foot placement was controlled and all were given the same instruction with regard to how to stand, it could not be confirmed that all participants' maintained the same posture throughout the 45-second FTV exposure period. Deviations in posture can influence vibration transmissibility due to changes in the surface contact area with the vibrating surface, which can influence the position of the bony structures and the degree of tension in different muscle groups of the trunk and the extremities, in turn changing the resonant frequency of the body structure [1,19,21,25,36,[38][39][40][41]. Thus, variations in the ankle and knee angles could have influenced the transmission of vibration from the platform through the feet and into the lower limbs.…”

Abstract.BACKGROUND: Exposure to foot-transmitted vibration (FTV) has been linked to injury; however, the biodynamic response of the foot to FTV has not been quantified. OBJECTIVE: The objective was to measure vibration transmissibility from the floor-to-ankle, and the floor-to-metatarsal, during exposure to FTV while standing, and to determine if FTV exposure frequency, or participant mass or arch index (AI) influence the transmission of FTV through the foot. METHODS: Participants' AI was measured. Four ADXL326, tri-axial accelerometers were utilized to measure vibration on the platform medial to distal head of first metatarsal, on the distal head of first metatarsal, on the platform paralleling the medial malleolus, and on the lateral malleolus. Participants were randomly exposed to FTV at 25 Hz, 30 Hz, 35 Hz, 40 Hz, 45 Hz, and 50 Hz for 45 seconds. CONCLUSIONS:The greatest transmissibility magnitude measured at the metatarsal and ankle occurred at 50 Hz and 25-30 Hz respectively, suggesting the formation of a local resonance at each location.

“…Exposure to foot-transmitted vibration (FTV) occurs when vibration enters the body at the feet and is transmitted through the feet and legs from vibrating tools, vibrating machinery, or standing on vibrating platforms or surfaces [1][2][3]. FTV exposure has been reported in mining, farming, forestry and construction [2,[4][5][6].…”

“…Hence, the magnitude and duration of vibration exposure are not the only risk factors associated with musculoskeletal injury to LHD operators. For example, in a study of large LHD operators Eger and colleagues found an operator's musculoskeletal injury risk score to be correlated with greater vibration exposure, poor working postures and higher levels of spinal compression [18]. It is also important to remember WBV exposure and the associated risk of musculoskeletal injury are also dependent on other factors such as driving speed, road surface, backrest contact, and muscle fatigue [10,19,20].…”

“…Installing a seat suited to the operating environment, capable of attenuating vibration is also critical to decrease the risk of spinal degeneration and related musculoskeletal injury and associated back pain [29,32]. Interventions aimed at improving driving posture should also be considered including the use of rotating seats, improved cab ergonomics and collision avoidance systems [12,18,33,34].…”

Abstract:The purpose of this study was to evaluate health risks to operators of large and small load-haul-dump (LHD) vehicles exposed to whole-body vibration (WBV), based on criteria established in ISO 2631-1, ISO 2631-5, and EU Directive 2002/44 EC. Studies simultaneously evaluating health risks based on all three standards are limited. Operator WBV exposure was measured in accordance with ISO 2631-1 using a tri-axial seat pad accelerometer. According to ISO 2631-1, four of the seven large LHD vehicle operators and three of six small LHD vehicle operators were exposed to WBV above the 8-hour vibration dose value (VDV) health guidance caution zone (HGCZ). According to the EU Directive 2002/44/EC criteria one of the seven large LHD vehicle operators and one of the six small LHD vehicle operators were exposed to WBV above the VDV daily exposure limit. However, health risks predicted by ISO 2631-5 criteria only placed one of seven large LHD vehicle operators and one of the six small LHD vehicle operators in the high probability of an adverse health effect category. Thus, the probability of adverse health effects, associated with WBV exposure during LHD vehicle operation, is suggested to be greatest based on the ISO 2631-1 8-hour VDV HGCZ and lowest based on ISO 2631-5 S ed criterion values.
