After knowing the Haizea-Llevant Table and explaining its operation and its purpose, I will explain the different screening items that should be assessed in children up to 3 months to detect delays in psychomotor development.
With the table in front, and after drawing a vertical line in the 3 months (the line must be made in the baby's age), we will talk about the actions that have been left and those that are crossed by the line, specifying between parenthesis the moment 50%, 75% and 95% of children do it and with stars (*, ** or ***) the importance of each item.
For example: Hand change objects *** (5.5; 6.3; 8). This item has three stars of importance, at 5.5 months (5 and a half months) 50% of children change an object by hand, at 6.3 months (equivalent to 6 months and about ten days) 75% and at 8 months 95% of children.
Sociability area exploration
• Reacts to the voice ** (1; 1.2; 3.1) Exploration (E): Words are spoken, gently, about 20 cm. behind the child, preventing breath from reaching him. Positive response (RP): If the child stops his activity, flashes or changes the breathing rate, etc.
• Distinguishes his mother through the smile ** (1.2; 1.9; 3) RP: If the baby smiles, staring at her mother when she hears her voice or when she smiles or makes a gesture without touching him.
• Recognize food (breast or bottle) * (1.8; 2.9; 4.8) RP: Calm down, get excited or open your mouth spontaneously in the presence of the breast or the bottle because you are hungry.
• Look at your hands * (2.2; 3; 4.5) RP: If you put one or both hands before your eyes and look at them carefully.
• Vertical optical chase * (2.5; 3.2; 4.5) Material needed (M): Flashy object (small red ball or other object of interest). E: While supine or sitting on your mother's lap, place the flashy object in front of you (30 cm), moving it 90º up and then down to its original position. RP: If you follow your route more than 60º
Language area exploration
• Watch for conversations ** (1.9; 2.3; 4.8) E: Ask the mother if when she is calm in a room and there are people talking, she regularly looks at them. RP: Answer yes.
• Laugh out loud * (3; 4; 5.5) E: Observe or ask the mother if the child laughs out loud, without having to tickle, but a social stimulus is valid (gestures, sounds ...). RP: Do it or answer yes.
Exploration area exploration
• Join hands ** (2.2; 3.2; 4) E: Observe if the child spontaneously joins or links the hands in the midline of his body. RP: Do it. ATTENTION: A marked asymmetry is a warning sign
Postural area exploration
• Prone cephalic straightening *** (1; 2; 3.5) E: Place the child upside down on a flat and hard surface. RP: If you raise the head of the plane approximately 45º, even intermittently.
• Step by sitting: head maintenance aligned with the trunk *** (2; 3; 4) E: Place the child in supine position (face up) and, taking it from the hands or forearm, gently incorporate it until sitting. It is important to keep in mind that if the child fixes his gaze on an object taller than his face - for example the examiner's face - he may not try to flex his head. RP: If you keep, actively, the head aligned with the trunk when it is located at about 30 degrees of inclination with the horizontal.
• Forearm support in the prone position ** (2; 2.9; 4.8) E: Place the child upside down on a flat and hard surface. RP: Raise the head and chest resting on the forearms. You can be encouraged to do so, but without touching him.
In a few days we will continue explaining the items covered until the age of 6 months.
