To evaluate, in primary care, the sensitivity of Heterophory-Vertical-Labile (HV-Labile) in ambulatory screening for Specific Learning Disabilities (SLD) and Developmental Coordination Disorder (DCD). in children aged 8 to 12 years.

General practitioners during a day of professional training on learning disabilities will be trained to perform the proprioceptive Maddox, to search for a HVLabile.

Each trained practitioner will then test at least six children aged 8 to 12 years old in his or her practice, seen at random

250 to 300 physicians will be trained as part of this research

EXPERIMENTAL DESIGN

• Cross-sectional study with prospective recruitment.
• Search for a Vertical Labile Heterophory (HV-Labile).
• Prescription of a standardized speech and language screening assessment for HV-Labile, and in the same number of children without HV-Labile by secondary coupling.
• Delivery of symptomatic questionnaire.
• In case of learning disabilities, the attending physician should look for a possible etiology.
• Adapted speech therapy care for more than six months.
• Speech and language therapy check-up at more than six months.

Inclusion Criteria:

The population studied is composed of children:

• from 8 to 12 years old
• seen for any reason for consultation in general practice
• Schooled in an ordinary environment since the Preparatory Course in France
• Francophone parents
• One of whose parents has signed the consent
• Consent of the child
• Social Insured

Exclusion Criteria:

The background and living conditions that may promote secondary learning disabilities, for example:

• Child with a known intellectual disability (Wisc)
• Child in IME (Institut Médico Educatif)
• Child followed in SESSAD (Specialised education service at home)
• Child not knowing how to answer the questions asked
• Child with a known etiology causing learning disabilities (epilepsy, autism spectrum disorder, hearing impairment, visual impairment (deafness, blindness, low vision))
• Child on treatment (antiepileptic, neuroleptic, antidepressant, anxiolytic)
• Child under the care of a psychiatrist,
• Child followed by the CMP (Centre médico-psychologique)
• Child living in an institution,
• Adopted child
• A child whose mother has experienced known depression during the child's early childhood (0-18 months) because it causes attachment disorders, which can impact the child's development, including learning
• Child of a family that has lived through more than two family recompositions
• Child known to be a victim of abuse.
• Out of school child.

To determine the presence of an HV-Labile

• Child with a known visual correction greater than + or- 2 diopters
• Known amblyopic child
• Known strabic child
• Child with no known binocular vision.

IPD will not be shared with other researchers.

An adjudication committee to determine the presence or absence of a specific learning disability will be set up, regardless of the presence of a central reference instability.
