An extended occupational exposure to hand-transmitted vibration, arising from the operation of hand-held power tools, has been associated with the development of an array of vascular, sensorineural and musculoskeletal disorders. The vibrotactile perception threshold (VPT) measurement technique is widely used to diagnose the sensory neuropathy of the hand induced by an extended exposure to vibrations. The measured values of VPT have been reported to depend on the contact force, vibration frequency and magnitude, and the temperature of the finger skin . Although the measured values of VPT responses of fingertips have been widely spread, no attempts have been made to develop adequate analytical models to study the mechanics of tactile sensation. This study proposes a finite element model of a human fingertip to study its responses to impinged vibration.
