Temporal relationship between postural and focal components of a whole-body reaching movement: a study case of short-term adaptation in microgravity condition.

In this study, the question of postural and focal components integration by the central nervous system (CNS) is investigated through whole body reaching task performance in microgravity. Because of the especially important difficulties suffered by one subject during parabolic flight, observation of temporal relationship evolution was allowed. From these results, short-term adaptation based on the restoration of this relationship could be postulated.
