Rett Syndrome (RS) is an X-linked, neurodevelopmental disorder that occurs primarily in females and causes significant impairment in cognition, motor control, and communication. Teachers and speech-language pathologists (SLPs) encounter girls with RS with increasing frequency as awareness of the disorder increases, yet the literature on clinical interventions with this population is limited. Parents, teachers, and SLPs were surveyed regarding the communication abilities of these girls. Respondents reported that girls with RS use multiple modalities to communicate, with eye gaze the most frequently used modality, followed by picture/symbol systems and body movements. This study provides clinical information for professionals working with girls with RS, and supports the need for additional research on strategies to improve communication in RS.
