Relation between vibrotactile perception thresholds and reductions in finger blood flow induced by vibration of the hand at frequencies in the range 8–250 Hz [PDF]
, 2014 Purpose: this study investigated how the vasoconstriction induced by vibration depends on the frequency of vibration when the vibration magnitude is defined by individual thresholds for perceiving vibration [i.e.

Evaluation and Measurement of Hand-Transmitted Vibrations
TRANSACTIONS of the VŠB – Technical University of Ostrava, Safety Engineering Series, 2017 Abstract The goal of this work is the effect of vibrations on selected professionals through questionnaire survey and implementation of experimental vibration measurements on a hand of employee. The observation of vibration effects was chosen in a company, where products are being shaped with pneumatic instruments and there is a risk of an exposure of ...

Negligent exposures to hand-transmitted vibration [PDF]
International Archives of Occupational and Environmental Health, 2007 If the negligence of an employer results in the disability in an employee, the employer is responsible, in whole or in part, for the disability. The employer is wholly responsible when the worker would not have developed the disability if the employer had taken all reasonable preventative measures.
