Plagiocephaly, the most common form of cranial deformity, has become more prevalent
in recent years. Many authors have described a number of sequelae of poorly defined etiologies,
although several gaps exist in their real scope. This study aimed to analyze the effects of physiotherapy
treatments and cranial orthoses on the psychomotor development of infants with cranial deformities,
complemented by protocolized postural exercises applied by the family. This prospective study on
different developmental areas included a sample of 48 breastfeeding infants aged 6 to 18 months who
presented with plagiocephaly (flat head syndrome). The Brunet–Lézine scale was used to perform
three tests for assessing the psychomotor development of infants, thus offering a measure for global
development. The results suggest that plagiocephaly is a marker for the risk of delayed development,
particularly in motor and language areas. This delayed development could be improved with
physiotherapy and orthopedic treatment, complemented by interventions by the infants´ relatives.
