The Hemorheologic Effects of Hand-Transmitted Vibration

Angiology, 1997
Vibration white finger (VWF) is an ischemic condition of the hands that is associated with long-term exposure to hand-held vibration tools. The pathophysiology of VWF remains unknown. The aim of this study was to assess the hemorheologic effect of acute hand-transmitted vibration. This study investigated 52 men divided into two groups: VWF=29, mean age

Scleroderma and occupational exposure to hand-transmitted vibration

International Archives of Occupational and Environmental Health, 2001
To determine whether occupational exposure to hand-transmitted vibration is a risk factor for scleroderma (systemic sclerosis, SSc), two case-control studies were conducted in the provinces of Trento and Verona, northeastern Italy.In the Trento study, 21 patients with a diagnosis of either systemic or localised scleroderma were recruited from those ...

Diagnosis of vascular injuries caused by hand-transmitted vibration

International Archives of Occupational and Environmental Health, 2007
For a reliable objective diagnosis of vascular injuries in hand-arm vibration syndrome (HAVS), the standardized cold provocation tests--finger skin temperature measurement during hand(s) immersion in cold water (FST test) and finger systolic blood pressure measurement during local cold exposure (FSBP test)--are widely used.

Assessment of Discomfort Due to Motorscooter Hand-Transmitted Vibration

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">Hand-transmitted vibration may be a cause of discomfort for two-wheeled vehicles. While there are international standards for the assessment of comfort in whole-body vibration exposure, there are not equivalent guidelines for hand transmitted vibrations.

Evaluation of human exposure to hand-transmitted vibration

Applied Acoustics, 1975
Abstract The relative importance of some of the parameters instrumental in the production of Vibration Induced White Finger have been identified. Difficulties encountered in the measurement of the vibration signal are mentioned, and possible means of overcoming them discussed.

Reduced Epidermal Nerve Density Among Hand-Transmitted Vibration-Exposed Workers

Journal of Occupational and Environmental Medicine, 2006
The objective of this study was to evaluate ultrastructural changes of epidermal nerve density (END) in workers exposed to hand-transmitted vibration.Ten male subjects with occupational exposure to hand-transmitted tools for 46.9 hours weekly for an average of 6.5 years were included in this study.

VIBRATORY CHARACTERISTICS AND HAND-TRANSMITTED VIBRATION REDUCTION OFWALKING TRACTOR

Transactions of the ASAE, 1998
The main excitations and characteristics of the hand-transmitted vibration of a walking tractor were investigated, and a new type of vibration-isolating handle grip, which equipped with an anti-vibration device, was designed. In accordance with ISO5349-1986(E)(ISO, 1986), the vibration-isolating effect of the new anti-vibration device was evaluated.
