• Description:
  Prolonged, intensive occupational exposure to hand-transmitted mechanical vibration, arising from the operation of hand-held power tools, is associated with hand-arm vibration syndrome (HAVS), an array of vascular, sensorineural and musculoskeletal disorders in the hand. Although the precise injury mechanisms of HAVS are not yet clear, previous studies have shown that HAVS is mechanically mediated, triggered by the exposure of the tissues of the hand-fingers to excessive vibratory stresses/strains. In this paper, we reviewed the recent advances in biomechanical approaches to assess the exposure of hand transmitted vibration. We will cover four aspects: driving-point biodynamic responses of hand-fingers, vibration distributions in finger and hand, vibration penetration into the soft tissues, and responses of the mechanoreceptors in the fingers to the vibrations. We will discuss both experimental and theoretical approaches applied to these cases. [Description provided by NIOSH]
