Virtual Reality Place in the Management of Body Dysmorphia Disorders in Anorexia Nervosa (PROSANOR)
Virtual Reality Place in the Management of Body Dysmorphia Disorders in Anorexia Nervosa : Comparison of the Recommended Management and Virtual Reality Care Programs With or Without Multisensory Remedy
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.
Study Overview
Status
Conditions
Detailed Description
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.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Female
- Age ≥ 15 to ≤ 26 years old
- Anorexic nervosa eating disorder according to the criteria of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5). As patients are hospitalized for anorexic nervosa, the medical diagnosis of each care center participating in the inclusions will be trusted
- Patient hospitalized (full hospitalization or day hospital) in one of the investigative centers for a minimum period of 6 weeks
- 14 ≤ BMI ≤ 18.5 for adult patients. For minors, Cole's curves will be used. The Body mass index (BM)I should be between the 1st percentile and the 10th percentile (if the weight curve shows a clear break indicating abnormal weight loss). For example, for a 15-year-old girl, the BMI should be between 14.5 and 16.8.
- Presence of body distortion (BSC ≥ 20%)
- French language mastery
- Affiliation to a social security system
- Signature of informed consent to participate in this study by the patient and by her parents in the case of underage patients
Exclusion Criteria:
- Associated major mental disorders (psychotic disorders, bipolar disorders, major depression)
- Neurological disorders (pyramidal or extrapyramidal syndromes)
- Substance addiction (drugs, alcohol)
- Any disorder likely to impair the reasoning, discernment or judgment abilities
- Psychological incapacity to answer the questionnaires
- Medical contraindication to the practice of physical activity (identical contraindication to people without anorexia. In fact, appropriate physical activity is prescribed in anorexic patients in order to reduce the cardiovascular risks, osteopenia or anxiety and allow them to become aware of an adapted physical practice (reduction of anarchic physical hyperactivity)
- Participation in other research programs or psychomotor treatments in parallel
- Pregnant or breastfeeding woman
- Persons under guardianship, curatorship or legal protection
- Blindness, eye infections, mask wounds, poorly balanced epilepsy, psychiatric disorders incompatible with virtual reality

Change in Physical self description questionnaire
Time Frame: 6 weeks
|
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).
|
6 weeks
|
Change in Body Image Questionnaire
Time Frame: 6 weeks
|
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).
|

Change in Weight gain
Time Frame: 6 weeks
|
Weight gain will be measured by weighting.
|

|
Change in Eating Disorder Examination Questionnaire
Time Frame: 6 weeks
|
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.
|
6 weeks
|
Anxiety measured by the State-Trait Anxiety Inventory (STAI-Etat-Trait)
Time Frame: 6 weeks
|
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.
