Functional Object Use (FOU) and Functional Communication (FC) on the Coma Recovery Scale – Pediatrics (CRS-P) in a Typically Developing Sample of Young Children. A Percent of sample meeting criteria for FOU and FC by age on CRP-S. Twenty-nine (88%) of the 33 participants displayed at least one of the two behaviors that signal emergence into a conscious state using either the original or modified CRS-P criteria. All 29 exhibited FOU, while 13 (45%) also showed FC. There were no cases in which FC occurred in the absence of FOU. Two of the participants who demonstrated FC were < 3 years of age (29 and 32 months). The remainder of the sample were at least 3 years old. B Percent meeting criteria for FOU by age on the original Coma Recovery Scale- Revised and CRS-P. FOU, defined by CRS-R as movements generally compatible with a specific function of object, was observed in all children over 12 months of age. A total of four (13%) of the 29 children who did not exhibit FOU based on the original CRS-R scoring instructions met the modified criteria for FOU. C Percent meeting criteria for FC by age on the original Coma Recovery Scale- Revised and CRS-P. Thirteen children, all at least 29 months of age, demonstrated functional communication (defined in the CRS-R as clearly discernible and accurate verbal or gestural “yes” or “no” responses to six consecutive visual or aurally based situational orientation questions or by the modified CRS-P criteria, which require clearly discernible and accurate verbal or gestural “yes” or “no” responses to six consecutive questions about images in a picture book). Among these 13 children, two participants (ages 32 and 37 months) who did not display FC utilizing the original CRS-R met criteria using the picture book question set.
