Abstract: Authors observed Raynaud’s phenomenon verified
by cold-provocation test and measuring finger systolic blood pressure in
a man driving a tractor installed with bush-cutter equipment for 5 years.
Vibration measurements carried out on the steering wheel of the tractor
showed acceleration superior to maximum allowable level according to Standard
ISO 5349. Other causes of a secondary Raynaud’s phenomenon were excluded
by means of detailed internal examination. Based on the clinical finding
and on the exposure data and lack of other ethiological factors the authors
think that the patient had vibration-induced Raynaud’s phenomenon. They
want to draw the attention to this so far unknown form of the hand-arm
vibration exposure. In addition they propose vibration measurements on
the steering wheel of the engine when it is equipped with any adapter because
in this case the vibration can change.
Key words: Hand-arm vibration, Raynaud’s phenomenon, bush-cutting equipment
