It is very hard to assess risky infants because of many problems like lack of cooperation, crying, discomfort ect. But with "Infant Motor Profile (IMP)" it is possible to assess motor behavior of risky infants in their daily environment. The assessment relays on video recordings so after recording the motor behavior many people can score the same children many times to have a certain idea about the infant. With this tool it could be easier to set a therapy program after determining the basic motor problem. In Turkey there are a lot of risky infants which later have diagnosed with Cerebral Palsy, Metabolic Disorders and other diseases. Also there are a lot of infants with Down Syndrome (DS) and Spina Bifida (SB). It has been known motor development is impaired with different childhood conditions but there is less information in literature about motor development of children with SB, DS and other diseases. With this study motor status of risky infants between 3- 24 months old will be explored, interrater and intrarater reliability of Infant Motor Profile will be analyzed.
