Myelomeningocele is a neural tube defect caused by the failure of the neural tube to close in the caudal part. The exposed spinal cord in myelomeningocele usually causes neural damage. Children with myelomeningocele have varying degrees of disability depending on the level of lesion and the presence of CNS-related anomalies. Lower limb weakness, sensory loss or deformity, and impaired bowel and bladder function are common disabilities that need to be managed. Performing multiple tasks simultaneously is a necessity in the daily lives of both adults and children. Although the majority of children with myelomeningocele lack the ability to ambulate and spend most of the day sitting, they have to perform dual tasking while performing activities of daily living as in all children. In the literature, dual task performance has been evaluated in many studies in adult individuals with diseases such as Multiple sclerosis, Stroke, Parkinson's, etc. However, there are few studies in the pediatric population in the literature. Most of the studies conducted in children include children with cerebral palsy and there are almost no studies in children with myelomeningocele. Therefore, the aim of this study was to compare dual task and upper extremity performance in children with myelomeningocele to typically developing peers.
