Effect of hand splints on stereotypic hand behavior of girls with Rett syndrome: a replication study.
The purposes of this study were to replicate a recent report of the positive effects of hand splinting on the stereotypic hand movement of children with Rett syndrome and to evaluate the generality of these results to a different setting. Two 5-year-old girls diagnosed with early Stage-III Rett syndrome were introduced to hand splints in accordance with the multiple-baseline design used in the Naganuma and Billingsley study. Splint wear ranged from 30 to 50 days for the two subjects. Data were analyzed as a percentage of time and as actual time in minutes. Unlike the previous study, in which a decrease in hand-wringing behavior was noted, neither subject in our study demonstrated a decrease in stereotypic hand behavior or a subsequent increase in independent feeding skills when wearing the splints. There was also no evidence of increased hand wringing following withdrawal of the splints. The differences in ages of the subjects and different functional levels (stages) may have been contributing factors to the conflicting results and should be considered in managing this group of children.
