Clinical observations indicate that many children with hemiplegic cerebral palsy (HCP) exhibit a lack of use or disregard of the affected upper limb. The aim of the present study was to develop, adapt, and verify the psychometric properties of a neuropsychological battery to assess body perception and representation disturbances in children with HCP. Three groups of children participated in this study, who took part in different phases of the validation process: one group of typically developing children (TD; n = 30; aged 4-6 years) and two groups of HCP children (HCP1: n = 12, aged 5-10 years; HCP2: n = 49, aged 5-13 years). Because no cognitive-neuropsychological model of body representation has been specifically developed for children, the tasks were designed based on a cognitive-neuropsychological model developed for adults. The chosen model comprises three levels of body representation: body schema, body structural description, and body image. The following steps were adopted in developing the instrument: development and choice of the tasks, selection and preparation of stimuli, adequacy and improvement of the instrument, semantic analysis of items, internal consistency, and feasibility and acceptability of application for TD and HCP children. The final set of tasks and items was chosen to balance the levels of difficulty and internal consistency. We concluded that the final battery was adequate and can be used to assess body representation disturbances in children with HCP.
