Coordination between voluntary movement and posture when pointing beyond arms length

A full protocol has been developed to study the relationship between the postural and pointing motor sub-tasks of a whole-body pointing movement. Subjects are asked to reach a target positioned in front of them, naturally or under some constrain imposition. Kinematic, dynamic and electromyographic data are simultaneously recorded by means of a passive motion capture system, three ground reaction force platforms and a wireless 32-channel electromyographic system. By exploiting dimensionality reduction algorithms and optimal control theory, the goal of such experiments is to improve the knowledge about the mechanisms exploited by the central nervous system to manage the complexity of such movements due to the large number of degrees of freedom involved.
