Body distortions are responsible for anorexic behavior reinforcing loops. It is necessary to target this behavior and develop appropriate therapies taking into account the perceptual (implicit) and conceptual (explicit) phenomenon of body representations. The main originality of the proposed program consists on combining virtual visual impulses and multisensory recalibration (touch, proprioception, vestibular sensations) in order to compare the body distortions evolution in anorexic patients with or without a multimodal care program including Virtual Reality from its own body scan, coupled or not to a multisensory remediation.
Rapid weight loss associated with mental anorexia leads to dysmorphophobia and body distortions. Patients perceive themselves to be bigger than they really are. Body distortions are responsible for anorexic behavior reinforcing loops. It is then necessary to target this behavior and develop appropriate therapies taking into account the perceptual (implicit) and conceptual (explicit) phenomenon of body representations. The current treatment programs which are recommended by the Haute Autorité de Santé (HAS) in France focus on the somatic, nutritional, individual and family psychological aspects. These recommendations hardly mention the bodily distortion phenomenon which frequently leads patients to relapse into the disease. The 3D body scanner enables to get awareness of the body through visual feedback allowing the patient to get a reassuring overview of her weight development. This projects aims to combine virtual visual impulses and multisensory recalibration (touch, proprioception, vestibular sensations) in order to compare the body distortions evolution in anorexic patients with or without a multimodal care program including Virtual Reality from its own body scan coupled or not to a multisensory remediation.

Patients benefit from the care recommended by the HAS, the virtual reality program, the multisensory remediation, and also the body scan.
Change in Body Dimensions Estimation task
Body overestimation bias will be assessed by the Body Dimensions Estimation task.
Time frame: 6 weeks
Change in Body Shape Questionnaire
The womens body image concerns will be evaluated by the Body Shape Questionnaire. This 34-items questionnaire is scored from 1 (= never) to 6 (= always) to obtain a global score.
Time frame: 6 weeks
Change in Physical self description questionnaire
The Physical self description will be measured by the Physical Self Description Questionnaire (PSQD). This questionnaire estimates 11 sub-dimensions of the physical self from 70 items on a continuum ranging from 1 (very negative perception) to 6 (very positive perception).
Time frame: 6 weeks
Change in Body Image Questionnaire
Patients bodily satisfaction will be assessed by the Body Image Questionnaire. This questionnaire consists of 19 items scored on 5 points. It gives a total body satisfaction score between 19 and 95 and 4 scores relative to 4 different factors (accessibility/closure, satisfaction/dissatisfaction, active/passive, serenity/tension).
Time frame: 6 weeks
Change in Weight gain
Weight gain will be measured by weighting.
Time frame: 6 weeks
Change in Eating Disorder Examination Questionnaire
Eating disorders will be assessed by the Eating Disorder Examination Questionnaire (EDE-Q). This questionnaire is divided into several sub-scores: restriction, dietary concerns, body shape concerns and weight concerns. It has 30 items scored from 0 (= no day) to 6 (= every day). A score for each subscale and an overall score can be obtained.
Time frame: 6 weeks
Anxiety measured by the State-Trait Anxiety Inventory (STAI-Etat-Trait)
Anxiety will be measured by the STAI-Etat-Trait . Each of the dimensions (STAI-state and Stai-trait) are measured by 20 items scored from 1 (= no or never) to 4 (= yes or almost always) which is summarized by a score.
Time frame: 6 weeks
