Abstract
Background: Assessment of body composition is important in determining energy needs. This is particularly important in children with limited mobility and poor nutritional status such as children with cerebral palsy (CP). One of the most accurate methods for assessing body composition is dual-energy X-ray absorptiometry (DXA), but for children with difficulty controlling their movement, this can be difficult. The BodyFIX is a novel immobilization device that has been developed to limit motion during medical procedures and may allow for accurate assessment of body composition by DXA in children with movement disorders. However, no studies have tested the accuracy of body composition measurements by DXA when the BodyFIX is used to limit subject motion. Purpose: The purpose of this study was to determine if the BodyFIX can be used to limit the motion of children during a DXA scan without affecting the accuracy of total body soft tissue and bone mineral estimates.
