Insights
General practitioners systematically assess child psychomotor development using "listen, observe, touch." This involves evaluating motor, language, and social skills, referencing standardized scales like Brunet-Lézine for early detection of developmental delays.
Area of Science:
- Pediatric developmental neurology
- Child psychology and developmental assessment
Context:
- Child psychomotor development is a key indicator of brain maturation and environmental interaction.
- General practitioners play a crucial role in monitoring development through systematic assessments at key ages (4, 9, 24 months, and 4 years).
Purpose:
- To outline the standard clinical practice for assessing psychomotor development in children.
- To highlight the four key dimensions of psychomotor development: global motor, fine motor, language, and social skills.
- To discuss the utility of the Brunet-Lézine psychomotor scale for standardized evaluation and the identification of developmental delays.
Summary:
- The assessment follows a 'listen, observe, touch' approach during routine consultations.
- Utilizes normative data from the re-evaluated and standardized Brunet-Lézine scale.
- Provides a practical framework for identifying and managing psychomotor delay.
Impact:
- Enhances early detection of psychomotor developmental delays in infants and young children.
- Supports general practitioners in providing comprehensive developmental surveillance.
- Contributes to timely interventions, optimizing long-term child development outcomes.
Abstract:
Psychomotor development in infancy and early childhood reflects the maturation of the developing brain interacting with environment. General practitioners are committed to follow child's development in the frame of a systematic assessment at 4, 9 and 24 months of age, and during the fourth year. The three basic steps of clinical practice: "listen, observe and touch", are highlighted. Psychomotor development includes four dimensions, which are checked during each consultation: global motor development, fine motor abilities, language and social skills. The French child's medical record contains several items, whose relevance is discussed in the light of normative data issued from the Brunet-Lézine psychomotor scale which has been recently re-evaluated and standardized. Finally, a practical approach to psychomotor delay is suggested.
