Vibrotactile sense in the hand-arm vibration syndrome.
Objectives The purpose of this study was to investigate disturbances of the vibrotactile sense and their relation to clinical symptoms and findings among male symptomatic workers suffering from the hand-arm vibration syndrome.
Methods Ninety-six such patients were interviewed and given a clinical and tactilometric examination.
The symptoms were classified according to the Stockholm Workshop Scale.
A sensibility index was used to quantify vibrotactile sense in the tactilogram.
Results An abnormal sensibility index (<0.8) was recorded for 57.3% of the patients (mean of 4 fingers), at least I finger being abnormal in 72.9% of the patients.
The sensibility index did not statistically differ between the patients suffering from sensorineural symptoms and those with vibration white finger.
The stages of sensorineural symptoms, according to the Stockholm Workshop Scale, corresponded with the sensibility index, whereas the stages of vibration white finger did not.
There were significant differences in the sensibility index between the fingers, between the right and left hands, and between the fingers innervated by the ulnar and median nerves.
Bilateral symptoms and cold intolerance were associated with considerable impairment of the vibrotactile sense.
Clinical median nerve involvement in the carpal tunnel was not reflected by the sensibility index. (...)
