[Hand and arm vibration syndrome caused by mechanical screw driver]

Authors performed angiological, neurological and radiological examination of 17 persons working with power screw-drivers. Vibration measurement of the tools was made too. 10 patients had symptoms and signs corresponding to the hand-arm vibration syndrome. The vibration of some tools exceeded the maximal allowable acceleration level according to ISO 5349. On the ground of the results authors conclude that some power screw-drivers can cause hand-arm vibration syndrome. The importance of choosing of the right tools and the significance of the periodical examinations are underlined in the prevention of the damages.
