Sammanfattning
The term "floppy infant" is used for describing children presenting with muscle hypotonia at or shortly after birth. These
floppy infants are usually a diagnostic challenge due to the many rare and genetic causes of hypotonia. It is common to start by
classifying the hypotonia as peripheral or central, but even from here the path to a diagnosis can be long. This article reviews the
literature, mostly retrospective studies done on floppy infants and presents a new simplified algorithm to help guide the
diagnostics of the hypotonic children.
