Vascular hand-arm vibration syndrome—magnetic resonance angiography

Hand-arm vibration syndrome.

The hand-arm vibration syndrome affects workers who perform tasks that generate vibration. Raynaud's phenomenon and sensory impairment of the fingers are the predominant effects. A history of hand-arm vibration (HAV) exposure in a patient with these symptoms should alert the physician to the diagnosis. Referral to a special clinic or hospital department for multiple clinical tests is required t...

Wood Density Impact on Hand-Arm Vibration

Nacrtak Despite technological advancements in machinery for timber harvesting, chainsaws are fre­ quently used in forest operations. In Austria 85% of the wood volume harvested (15 million m3) are cut by chainsaws. The two most frequently documented ergonomic threats during motor manual felling include exposure to noise and vibration. This paper presents the results of exposure to hand-arm vibr...

The hand-arm vibration syndrome: an update.

New frequency weighting of hand-arm vibration.

A new frequency weighting method to assess hand-arm vibration exposure is proposed in this paper. The influence of frequency components was first estimated using the method of multivariate analysis, then a simple form of the weighting curve was introduced. Compared with the frequency weighting in the current ISO 5349-1 (2001), the proposed weighting can better explain the relationship between r...
