Characteristics, head shape measurements and developmental delay in 287 consecutive infants attending a plagiocephaly clinic Hutchison B et al. - Physical examination of infants with head shape deformities is essential in order to rule out craniosynostosis. Infants with deformational plagiocephaly frequently have neck muscle dysfunction. The authors postulate that the higher than expected number of developmental delays may be related to the effects of supine sleep position, low or variable tone, lower activity levels, male gender and neck muscle dysfunction.
