Evaluation of joint type modelling in the human hand

This short communication presents preliminary results from an extensive investigation of joint modelling for the human hand. We use finger and hand movement data recorded from both hands of 110 subjects using passive reflective markers on the skin. Furthermore, we use data which was recorded from a single Thiel-fixated cadaver hand using also passive reflective markers but fixed to the bone. Our data clearly demonstrate that, for wrist and finger joints, hinge joint models are sufficiently accurate to describe their movement in Cartesian space.
