EFFECT OF SINUSOIDAL VERTICAL VIBRATION ON THE URINARY SEDIMENT IN MAN
Abstract
Experiments were conducted to determine whether sinusoidal, low-frequency vertical vibration for 1 minute at subjective tolerance levels could produce renal damage. Two groups of vibrated sitting subjects (frequency, 4 to 9 cps) were compared to a control group which had never been exposed to vibration experiments. One group had long experience, varying from 6 months to 2 years, with experimental sinusoidal vibration at subjective tol rance levels. The other group was experiencing its first shake at high levels (near subjective tolerance). No difference could be detected in the urinary sediment between the two experimental groups or between the vibrated groups and the control subjects. Although the data does not indicate renal damage, it might have occurred if the vibrations had been continued for a longer time period. (Author)
