It is thought to be due to damage of small blood vessels and nerve endings in the fingers and can affect up to 1 in 10 of power tool users.

Symptoms include altered sensation, pins and needles, pain and loss of power in the fingers and hand. In severe cases the injury can lead to serious injury to the finger tips.

areful history detailing prolonged and frequent exposure to vibration is highly suggestive of HAVs, however testing grip strength, testing respond to cold exposure, Doppler blood flow tests and examination of fine hand movements may be needed to confirm the diagnosis of HAVS.
