The following conditions are common in infants who stand on their toes: 1. This is a normal phenomenon, mostly seen in infants within 6 months of age, because the muscle strength of both lower limbs is poor, when standing on the armpits, a brief toe landing can occur, which will disappear after 6 months of age, if the toe landing still occurs after 6 months of age, it is an abnormal condition and requires prompt consultation at the hospital. 2. Most of them are the characteristic manifestation of spastic cerebral palsy, and need to be seen by the pediatric rehabilitation department for early rehabilitation training. 3. Plantar tactile dysfunction, mostly because infants often wear thick socks or wrapped with shoes during infancy, which reduces plantar tactile cognition and leads to toe landing. The premise is to rule out muscle tone abnormalities.
