Abstract

Objective

The present study aimed to clarify the range of involvement for hand-arm vibration syndrome (VS) in the median, ulnar and radial nerves of the hand.

Methods

Sensory nerve conduction velocities (SCVs) for 3 nerves in the hands and arms were examined for 34 patients with VS and 23 age-matched controls. Neuropathy types were classified by possible carpal tunnel syndrome (CTS), Guyon’s syndrome and digital neuropathy in three nerves.

Results

SCV in the median nerve (middle finger, wrist–elbow) and ulnar nerve (little finger, wrist–elbow), and amplitudes of the median nerve (wrist–proximal and distal parts of the middle finger), ulnar nerve (wrist–proximal and distal parts of the little finger; forearm–proximal part of the little finger; upper arm–proximal part of the little finger) and radial nerve (dorsal side of the hand–thumb) were significantly reduced in VS patients compared with controls. According to subject classifications based on the results of SCV and amplitude of nerve action potential, 52.9% of VS patients displayed multi-focal neuropathy including digital neuropathy, possible CTS and/or Guyon’s syndrome.

Conclusion

These findings suggest that VS affects all three nerves in the hand. According to classification results, the main disorders of peripheral nerves comprise digital neuropathy.
