Whole-body vibration (wbv) has been implicated as a cause of low- back pain in the industrial workforce. The U.S. Bureau of Mines conducted two studies to determine whether random, low-intensity wbv had an effect on maximum back extensor strength and on back endurance. In the first, maximum back strength was measured before and after 30-min periods of vibration while seated in four different seats. In the second, back endurance was measured before and after 30-min periods of vibration while positioned in eight different seating postures. Results from the two studies indicated that back muscle function is not compromised by wbv at the intensity and duration studied.
