| Research Abstract |
For the purpose of diagnosing hand-arm vibration syndrome, authors investigated finger blood pressures during immersion of one hand in cold water and somatosensory evoked responses to electrical stimulation of the skin.
Four vibration syndrome patients with Raynaud's phenomenon and for vibration syndrome patients without Raynaud's phenomenon were subjected to measurement of finger blood pressure as well as circulatory function tests used conventionally in Japan. Five healthy subjects were measured somatosensory evoed responses to electrical stimulation of the skin and of the median nerve.
Finger blood pressure correlated well with findings of skin temperature, the nail press test and plethysmograph. The difference of finger blood pressures during immersion test between the patients with Raynaud's phenomenon and the patients without it was larger than those of the conventional tests.
Somatosensory evoked responses to electrical stimulation of the skin were very similar to those to mechanical stimulation by pin-prick but not to electrical stimulation of the median nerve. Therefore, we concluded that our new method is useful and convenient for detecting disorder of mechanoreceptors of hands in vibration syndrome patients.
