Effects of whole-body vibration (WBV) exposure on professional drivers were predicted using a 45 subjects sample of healthy volunteers from both genders. These volunteers preformed a visual/motor accuracy evaluation test, the 'omega test', inside a vehicle (van) under three different WBV exposure conditions, van halted, van performing a circuit on asphalt, and on cobblestone. WBV levels of the stated conditions were statistically different and impairment upon subjects' performance was found. The statistical significant difference encountered between the subjects performance under the two whole-body vibration profiles (asphalt and cobblestone), seems to indicate that the vibration levels also represent a variable to be taken under consideration. No gender related difference was found.

“…The accelerations for this in case are in lesser bands of frequency (from 4 to 8 Hz), without distinction between the assayed parts, that is, occur in such a way in the wooden floor as on the seat of the armchair. The works of Griffin [5] and Ishitake [6] show that, in the band of frequency from 1to 30Hz, people present difficulty to keep position and consequences. These authors also register the great incidence of problems on the back region, proceeding from vibratory effect.…”

The objective of this work is to evaluate the levels and vibratory effects that the passengers who use intermunicipal road buses are submitted. In the study, measurements of the accelerations produced in the vertical direction had been carried through according with norm ISO 2631, in two bus bodyworks, of different manufacturers, in a normal situation of use, in three points of it (frontal, central and back). With the measurements it was possible to point which are the places in the bodywork interior and the points in the seats that produce greater accelerations r.m.s. The results had been evaluated and compared with the curves values established for norm ISO 2631 in relation to health and comfort and in relation to fatigue, comparing the two tested bodyworks.

“…On the other hand, it is necessary to separate this power into each frequency band in order to assess the gastrointestinal tract function objectively. In humans, the frequency band is centered on three cpm in order to detect the coherency of slow waves of the stomach and to classify them as bradygastria, normal, and tachygastria [2,10]. In the horse, because the total EIG power is distributed around 6 cpm [22], the frequency band was separated into 3 cpm (1.8 to 4.5 cpm), 6 cpm (4.5 to 7.5 cpm), 9 cpm (7.5 to 10.5 cpm) and 12 cpm (10.5 to 12 cpm).…”

It is thought that in order to effectively treat gastrointestinal dysfunction, it should be detected at an early stage. The present study aimed to observe the movement via Electrointestinography (EIG) in the small intestine, cecum, right ventral colon and right dorsal colon, and to examine the procedure for assessing gastrointestinal function. Seven healthy thoroughbred horses were used. They were allowed food twice a day. EIG was measured at ten-minute intervals over a 24 hr period, and running spectral analysis was used. As a result, it was clear that EIG could non-invasively assess gastrointestinal function by setting the cutoff value of the frequency band to 1.8-12.0 cpm for a part of the digestive tract which is in a comparatively fixed position. The running spectral analysis could be used to visually interpret the change in the EIG power. In the small intestine, cecum, right ventral colon and right dorsal colon, a significant increase was observed for about 1-4 hr during which feeding took place at the maximum amplitude and the total power of the EIG wave. Because 3 cpm of the total power could be influenced by artifacts, analysis at 6 cpm is recommended, when the total power was assumed to be an indicator. In conclusion, it was considered capable of effectively detecting two indicators of 6 cpm of the total power and maximum amplitude for assessing change in the digestive tract voltage in medical practice.
