Individual finger forces acting on a grasped object during shaking actions

Article Abstract:

Studies of the forces acting on manipulated objects during shaking motions show that finger coordination changes in relation to shaking direction. Regardless of the shaking direction and speed, the absolute grip force in the index finger is the largest, followed by the middle, ring, and little finger forces. The changes in shaking speed, from moderate to fast, changes the grip forces for all the fingers.

Effect of gloves on prehensile forces during lifting and holding tasks

Article Abstract:

The effects of the thickness and material of gloves on grip force and performance time during lifting and holding of a small object, were investigated. The performance time for lifting the object was not affected by the variation of glove thickness. Participants were found to use a larger grip force with cotton gloves than with rubber gloves for the slippery surface, but not for the non-slippery surface.

Temporal and force characteristics of fast double-finger, single-finger and hand tapping

Article Abstract:

Issues concerning the motor functioning of fingers and hand are examined, focusing on a study that compares force data for alternate finger tapping of the index and middle fingers and for one-finger tapping, as it applies to ergonomic research. Results indicate index finger has greater motor ability than the middle finger.
