Hand-Arm Vibration Syndrome (HAVS)
Hand-Arm Vibration injury is a general term for damages to human hand arm and fingers caused by vibration. Vibration injuries occur frequently in multiple occupations and industries, e.g. in automotive repair shops, construction work, engineering, dental care foot care and many more.
Vibration damages can be irreversible, especially the neurological part, if not discovered in time. Incipient changes in the nerves, i.e. reduction of sensibility, can be detected with Multi-Frequency Tactilometry.
The Carpal tunnel syndrome is another common neurological vibration damage. If this injury is cured in time, the prognosis is usually good for a full recovery.
During the whitening, caused by a temporary closure of blood circulation to parts of the fingers or the hand, the person gets numbness in the areas that have become white. When the blood then returns, i.e. during the release of the vasospasm, the person is often experiencing a major discomfort such as tingling and pain.
Vibration injuries are common in many occupations where vibration exposure is common, e.g. construction workers, cutters, vehicle repair, sheet metal workers, electricians and welders. The problems are also common in occupations where the hands are exposed to very high frequency vibrations, such as dental technicians and dentists.
