Occupational exposure to vibration through the use of power- and pneumatic hand-tools results in cold-induced vasospasms, finger blanching, and alterations in sensorineural function. Collectively, these symptoms are referred to as hand-arm vibration syndrome (HAVS). Currently the International Standards Organization (ISO) standard ISO 5349-1 contains a frequency-weighting curve to help workers ...

To assess high-level low frequency noise in the working environment, adverse extra-aural effects caused by the noise should be taken into account. The human body vibration induced by low frequency noise, 'noise-induced vibration', was measured on the body surface and the equal-acceleration level contours of the vibration were tentatively estimated. With these contours, we can predict the magnit...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

Mechanical loading can modulate tissue plasticity and has potential applications in rehabilitation science and regenerative medicine. To safely and effectively introduce mechanical loads to human cells, tissues, and the entire body, we need to understand the optimal loading environment to promote growth and health. The purpose of this research was 1) to validate a limb vibration and compression...

exposure to vibration is the cause of some occupational injuries and diseases. objective of this study was determination of vibration exposure of tractor drivers and assessment of musculoskeletal disorder . this cross-sectional and descriptive- analytical study was administrated to 95 tractor drivers to census method and measuring induced vibration to the drivers was done in three axis, x, y, a...

Krajnak, K., R. G. Dong, S. Flavahan, D. Welcome, and N. A. Flavahan. Acute vibration increases 2C-adrenergic smooth muscle constriction and alters thermosensitivity of cutaneous arteries. J Appl Physiol 100: 1230–1237, 2006. First published December 8, 2005; doi:10.1152/japplphysiol.00761.2005.—The vascular symptoms of hand-arm vibration syndrome, including cold-induced vasospasm, are in part ...

Aim of this study was to determine sensitivity and specificity of the mastoid vibration test in patients who had suffered an attack of vestibular neuritis. Results were compared with the caloric test and two bedside tests of vestibular function (head shaking test and head thrust test). Results are reported in 28 patients who had a residual vestibular deficit 6 months after acute neuritis and in...

Nowadays, vehicle-induced vibration is a subject matter interest in the bridge monitoring field. As compared to other types of excitation such as earthquake and accidental impact, the vehicle-induced vibration is often being less considered during the design process of the bridge. The newly implementedcode also does not emphasize on the vibration check for vehicular bridge and requires the engi...
