Neurologic Exam-Pediatric | 6-month-old | Normal | Postural Reflexes - Lateral Propping
6-month-old - Normal 13 - Postural Reflexes - Lateral Propping: Lateral propping or protective extension is essential for the baby to be able to sit independently. This postural reflex develops at 5 to 7 months of age. Anterior propping actually develops first, then lateral propping. For anterior propping the baby will extend the arms forward to catch himself and prevent falling forward. Lateral propping occurs when the baby is falling to one side or the other and he extends the arm laterally to catch himself. Asymmetric lateral propping can be an early sign of hemiparesis. The baby will prop on one side but on the paretic side he will not extend the arm to catch himself.
