Systemic Effects of Segmental Vibration in an Animal Model of Hand-Arm Vibration Syndrome

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...

The hand-arm vibration syndrome: an update.

Hand-arm vibration exposure and the development of vibration syndrome.

To evaluate the circulatory disturbances, sensory disturbances and damage to muscles and joints by chain saw vibration exposure, the process of the deterioration of the symptoms with chain saw operating time was studied. Subjects were classified into eight groups according to TOT (Total Operating Time): Group 0, 46 controls; Group A, 39 operators (< 2,000 hours); Group B, 53 operators (2,000-4,...

Clinical assessment of hand-arm vibration syndrome.

The clinical assessment of patients thought to be suffering from hand-arm vibration syndrome (HAVS) requires the use of multiple vascular and sensory tests. In a family physician's office, Adson's, Allen's and cold water immersion of the hands are the only feasible vascular tests, while the sensory tests have to be limited to assessing impairment of skin sensitivity and manipulative dexterity. ...

Dose-response relationship between hand-transmitted vibration and hand-arm vibration syndrome in a tropical environment.

OBJECTIVES The dose-response relationship for hand-transmitted vibration has been investigated extensively in temperate environments. Since the clinical features of hand-arm vibration syndrome (HAVS) differ between the temperate and tropical environment, we conducted this study to investigate the dose-response relationship of HAVS in a tropical environment. METHODS A total of 173 male constru...
