SDR yields durable reduction in spasticity after 10 years. Early improvements in motor function are present, but at long-term follow-up, these improvements were attenuated in GMFCS II and III and were not sustained in GMFCS IV and V.
The results allow better counselling of parents about outcome of infants with PP, reducing anxiety, and allowing more rational selection of management modality.
For optimal outcome, current evidence supports use of repositioning in young infants and start of orthotic helmet treatment for infants with significant DP at 4-6 months. Further research is needed to better understand the parameters for use (stratified by age and severity), long-term outcomes and natural history and the impact on caregiving, as well as the cultural significance of head shape.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
