  • Title: The vibrotactile threshold (VT) at the fingertips of chain saw operators.
    Author: Ahrend KD, Hartung E, Dupuis H.
    Journal: Cent Eur J Public Health; 1995; 3 Suppl():85-7. PubMed ID: 9150979.
    Abstract:
    The vibration sensitivity of the skin at the ten fingertips was tested with 72 chain saw operators examined due to VWF-disease and compared with controls. The vibrotactile perception threshold (frequency f = 125 Hz, load p = 1.3 N) proved to be 3 to 5 times as high for the exposed group compared to controls. There was no correlation between vibration sensitivity and peripheral circulation found in cold provocation test. Two different testing instruments (pallaesthesiometer = vibrotactometer) showed significant differences in results probably due to different technical details of the methods. It may be concluded that a standardization of the instrumentation and method is necessary for testing the vibrotactile perception threshold as a part of the nervous function in a comparable manner.
