Real time relationship between individual finger force and grip exertion on distal phalanges in linear force following tasks
Fingers are among the most complex and important body parts for accomplishing tasks in daily and life as they consist of many joints and muscles. Past studies on fingers have mainly focused on grip exertion under consistent pressure, how cylindrical grip size affects maximum force output and comfort, and the tendency of force distribution on a surface. There has not been extensive research done on the functions of each finger in a dynamic grip exertion task.
Individual finger force in a grip task is an important indicator in rehabilitation engineering and precise control of manipulator because disorders in any of the fingers will affect the stability or accuracy of the grip force. By obtaining and analyzing data from linearly grip force following tasks at different submaximal voluntary contraction levels, the study concludes: the middle finger is the primary output of grip force, the index and ring finger had a complementary relationship and plays a vital role in the precise control of grip force, and the pinky finger serves to provide minor adjustment to the grip action.
Grip is the most fundamental and common action of the human hand. It requires the collaboration between all of the fingers. The precision and stability of the grip is a critical part in ergonomic engineering, especially in the design of handles and controllers. A finger injury or control disorder could cause many inconveniences, which is why the study of grip mechanics (namely, how fingers generate force and adjust during a grip motion) greatly contributes to fields such as rehabilitation engineering and manipulator design.
