RESUMEN
BACKGROUND: Patients with spina bifida experience sensory and motor paralysis and complications in the form of deformation and skin problems of the lower limbs. Enhancing their awareness of the paralysed lesions could be helpful for these patients to prevent secondary disorders. This study sought to investigate to what extent children with spina bifida are visually aware of their body parts and, in particular, to their paralysed lesions. METHODS: Participants included children with spina bifida (n = 10) and typically developing control children (n = 10) between the ages of 5 and 11 years. All participants were shown still images of themselves on a monitor after which their gaze direction was measured using an eye tracker, with or without providing an instruction to direct their attention to their limbs. The gaze direction data were analyzed and compared between children with spina bifida and the control children. RESULTS: Children with spina bifida paid visual attention to their bodies in a manner similar to that of control children. Prompts to direct their attention to their limbs were effective in both groups; however, the degree of efficacy in children with spina bifida was inferior to that in control children. CONCLUSIONS: Promotion of visual awareness to their paralytic parts could be a reasonable and effective method for children with spina bifida to improve their understanding and recognition of their body and prevent associated skin problems.

BACKGROUND: Patients with spina bifida suffer from motor paralysis and sensory disturbance, secondary deformation of the lower extremities, and development of decubitus ulcers. A deep understanding of one's body, such as identifying the names, functions, relationships, homology (e.g. upper and lower limbs) and relative position of body parts, may prevent secondary disorders. The awareness of the body and its characteristics in children with spina bifida has not been fully elucidated. This study aimed to investigate how children with spina bifida perceive their bodies, especially their paralyzed parts and related or homologous ones. METHODS: Participants included 36 children with spina bifida and 14 control children, aged 5-11 years. They were asked to draw self-portraits, and to answer questions about the names of body parts. The number of drawn body parts in the pictures and the correct response rates to the questions were quantified and compared between children with spina bifida and control children. RESULTS: Children with spina bifida drew fewer hands, legs, and feet than control children. In the verbal tests, children with spina bifida had a lower correct response rate than control children on questions concerning the upper limbs, hands, trunk, and feet. CONCLUSIONS: Children with spina bifida have diminished visuospatial and lexical-semantic body knowledge of the paralyzed parts and related organs.
