What is hypotonic cerebral palsy?
Hypotonia is diminished muscle tone. The infant or child with hypotonic cerebral palsy appears floppy — like a rag doll. In early infancy, hypotonia can be easily seen by the inability of the infant to gain any head control when pulled by the arms to a sitting position (this symptom is often referred to as head lag). Children with severe hypotonias may have the most difficulty of all children with cerebral palsy in attaining motor skill milestones and normal cognitive development. Hypotonic cerebral palsy is often the result of severe brain damage or malformations. It is believed that hypotonic cerebral palsy is the result of an injury or malformation at an earlier brain developmental stage than that which causes spastic or choreoathetoid cerebral palsy. Hypotonia in infancy is a common finding in many neurological conditions, ranging from very mild abnormalities to severe or even fatal neurodegenerative or muscle disorders. It is important to note that many children with spastic cere
