The Effect of the Postures of the Middle Finger and the Wrist Upon the Movement of the Index Finger: Preliminary Studies

This paper created a preliminary index of the range of motion of the index finger with the effect of the middle digit suspended at minimum and maximum flexion. A follow-up study was performed creating a preliminary index of the range of motion of the fingers on each hand and the effect of the wrist joint suspended at minimum and maximum flexion. The resulting indexes can be used by professionals to study the average limitations, by designers to build better tools, and by researchers to further the fields of anthropometries, biomechanics, and the arts.
