Beside these well-known symptoms (positive symptoms (such as delirium and delusions), negative symptoms (such as affective flattening and impoverishment of speech), disorganized behavior, patients with schizophrenia show different kinds of cognitive alterations and motor abnormalities. In schizophrenia, postural impairment could increase the attentional cost of daily motor tasks, leading to a lack of attentional resources, essential to achieve complex cognitive tasks. The intrication of cognitive and postural processings (both impaired in schizophrenia) can be explored by using of a dual-task paradigm.

This study assesses a psycho-corporal training (8 weeks psycho-corporal training) benefits on both postural (increased automation of balance control) and cognitive processings (smaller impact of the dual-task condition on attentional performances) in population of patients suffering from schizophrenia.
