Modeling of the interaction between grip force and vibration transmissibility of a finger

Extended exposure of the hand to vibratory or repetitive loading has been associated with vascular, sensorineural, and musculoskeletal disorders, such as hand –arm vibration syndrome [1], carpal tunnel syndrome [2], and flexor tenosynovitis [3]. Strong evidence indicates that the initiation and development of the musculoskeletal disorders of the hand are related to the mechanical stress and strain in the soft tissues. The occurrence of vibration white f inger (VWF) among exposed workers has been related to impaired blood circulation in the fingers resulting in degeneration of the vascular system [4], which is associated with high contact pressures at the tips of index and middle fingers under tool vibrations [5–7].
