title: [Neck and upper limb disorders caused by combined exposures to ergonomic risk factors and hand-transmitted vibration].
abstract: A review of neck and upper limb disorders caused by combined exposures to hand-transmitted vibration and ergonomic risk factors (repetitiveness, force, posture) suggested the following conclusions: (1) hand-transmitted vibration has a dominant role in the etiopathogenesis of Raynaud's phenomenon and various forms of peripheral neuropathy with sensory impairment (digital, multifocal) in users of vibrating tools; (2) vibration of low frequency and high amplitude from percussive tools concur, together with adverse ergonomic factors, to produce degenerative changes in the bones and joints of the upper limbs, mainly in the wrist and elbow; (3) there is strong epidemiological and experimental evidence that combined exposures to hand-transmitted vibration and physical load are associated with an excess risk of carpal tunned syndrome; (4) there is limited evidence for an association between Dupuytren's contracture and vibration exposure owing to the small number of currently available epidemiological studies; (5) there is insufficient evidence for a contribution of hand-transmitted vibration to the development of chronic pain and clinical syndromes in the neck and upper limb, while excessive physical load and ergonomic stress have a primary role in the etiopathogenesis of these disorders.
