Ambulatory Screening for Specific Learning Disabilities (SLD) and Developmental Coordination Disorder (DCD).

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Design Details

Primary Purpose: Screening
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Comparison of the presence of a specific learning disability, or a Developmental Coordination Disorder, in the case of the presence or absence of referential instability of central origin.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Presence of HV-Labile<br>Presence of vertical heterophoria labile with proprioceptive Maddox | Diagnostic Test: Diagnostic of specific learning disabilities or of Developmental Coordination Disorder<br>* Speech therapy assessment, or occupational therapy. In case of pathological disorder, search for a sensory disorder, and therapeutic management. If the pathological disorder persists for more than six months, elimination of a secondary etiology.<br>|

In case of pathological disorder, search for a sensory disorder, and therapeutic management. If the pathological disorder persists for more than six months, elimination of a secondary etiology.<br>|
