Study of 3-D human movements: influence of the forearm bone morphology on the magnitude of the prosupination motion

The purpose of this work is to study the human movements and more precisely the rotation, of the forearm, called the prosupination motion. From medical papers which have analysed the kinematics aspects, we deduce a computer simulation of the prosupination motion. We evaluate the magnitude of the motion detecting automatically collisions between the two bones during the movement. The collision detection technique allows us to deduce the influence of the bone morphology (malformations) on the magnitude of the prosupination motion
