Abstract

Stereotyped hand mannerisms are a defining characteristic of Rett syndrome. This study examined the effects of social interaction/activity on the frequency of stereotyped hand mannerisms in seven individuals with Rett syndrome. The percentage of 15 s intervals with stereotyped hand mannerisms was recorded during repeated 10 min sessions under two conditions in an ABAB reversal design. The High Social Interaction/Activity condition occurred during a mealtime when the individuals also received high levels of social interaction from a staff person. In the second, Low Social Interaction condition, a staff person was present but did not interact with the individual and no activities were presented. The trend was for more Stereotypic hand movement in the Low Social Interaction/Activity condition. However, there was a considerable amount of individual and within condition variability. The results suggest a need for individual assessment in order to develop educational interventions to attenuate stereotyped hand mannerisms in persons with Rett syndrome.
