Evaluation of transmissibility properties of anti-fatigue mats used by workers exposed to foot-transmitted vibration

Mallorie Leduc, Tammy Eger, Alison Godwin, James Dickey, Michele Oliver


A study reported considerable differences in the dominant frequency associated with locomotive operation compared to drilling or bolting off from platforms, suggesting a rationale for greater reports of vibration-induced white feet in workers with a history of exposure to higher frequency vibration at the feet. Ten participants, with no history of lower body musculoskeletal injury, head injury, diabetes, vasculopathy, or neuropathy, participated in this study. A four mat by two vibration exposure profile experimental design with one repeat was carried out. A mat effective amplitude transmissibility (MEAT) value greater than 100% indicated vibration was amplified as it traveled through the mat while a value less than 100% suggested the mat attenuated the vibration. Positive anecdotal feedback provided by miners in a field study also supports continued use of mats in underground mines.
