Analyse cin\'{e}matique de l'\'{e}paule chez des patients h\'{e}mipar\'{e}tiques lors de la saisie d'objets pesants

The aim of this study is to produce a kinematic analysis of movements of the shoulder complex when hemiparetic patients achieve the grasping of weighted objects. We propose to describe the influence of the weight on kinematic characteristics of the gesture and to establish the relevance of several quantitative indexes concerning the quality of the grasping gesture.
