Abstract
The measurement of vibrotactile perception threshold has been often used to assist in the diagnosis of the severity of peripheral neuropathy associated with hand-arm vibration syndrome (Lindsell and Grifun, 1999). The vibration perception threshold has been found to depend on the contact force, vibration frequency and magnitude, and finger skin temperature. However, the biomechanics of the tactile sensation underlying these phenomena remains unclear. Since the mechanoreceptors embedded in the skin sense their mechanical environment, the variations in the test conditions will influence the stress/strain distributions in the soft tissues and thus affect the reliability of the test results. The purpose of the present study is to analyze, theoretically, the effects of decoupling of the probe from the skin surface on vibrotactile threshold.
