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.

the losses of postural and attentional control
To analyze the losses of postural and attentional control under dual-task condition. Losses of postural and attentional control are calculated by one composite score named mu (Baddeley, Della Sala, Papagno, \& Spinnler, 1997).
Time frame: At 8 weeks
cognitive decrement
To compare mean values of the cognitive decrement between baseline and 8 weeks in which the Redundancy value of the responses sequence to the random number generation task were analyzed using RgCalc® software (Towse \& Neil, 1998).
Time frame: At 8 weeks
postural decrement
To compare mean values of the postural decrement between baseline and 8 weeks in which the confidence Ellipse is used as main criteria to evaluate the participants balance ability postural sway platform (WIN-POSTURO Médicapteurs®).
Time frame: At 8 weeks
