Abstract

A study was carried out to determine if hand-arm vibration exposure is associated with current perception threshold (CPT) measurement in the fingers after controlling for neuropathy proximal to the hand measured by nerve conduction testing. All of the 165 participants had a detailed occupational and medical history and physical examination to ensure that no other conditions were present that might affect sensation in the hands. All of the participants had nerve conduction tests and measurement of CPT in each hand. The results show that 48 participants have median neuropathy on the right upper extremity and 30 on the left and 10 had ulnar neuropathy on the right side and 8 on the left. It is therefore found that despite the high prevalence of proximal neumpathy in workers exposed to hand-arm vibration, there is an effect on nerve fibre damage in the fingers due to hand-arm vibration that cannot be explained by common median or ulnar neuropathies proximal to the hand.
