Among these infants, 101 infants were treated with helmet therapy or postural correction training. After matching by infant's age and time of therapy, three retrospective cohort studies of 56 infants were conducted for infants with plagiocephaly, brachycephaly and asymmetrical brachycephaly, respectively. The cephalic ratio (CR), radial symmetry index (RSI), cranial vault asymmetry (CVA) and cranial vault asymmetry index (CVAI) were compared between two groups before and after treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Before treatment, no significant differences in CR, RSI, CVA and CVAI between groups were found.
