In their recent paper, Philippi et al. [1] proposed a welcome evaluation scale which may be used across the different approaches that have been applied to infants with idiopathic asymmetry. It provides a functional view based on posture, spontaneous and reactive movements, hopefully unifying the host of syndromes under which these children came in the past. All these disorder categories (briefly reviewed in the paper’s introduction and to which Fulford’s and Brown’s squint-baby syndrome [2] may be added) are associated with particular differential diagnosis, ranging from muscle contracture to congenital bone deformity. In the context of developmental neurology, and in particular of reevalutaion of the cerebral palsy concept [3], it would appear relevant to stress the differences between idiopathic infantile asymmetry and hemiplegic cerebral palsy in the age group studied by Philippi et al. [1]. To characterize the clinical elements that may discriminate between hemiplegic cerebral
