Various linear measurements were made of 100 children with cerebral palsy to evaluate the effects of various factors on growth, and to investigate the use of alternative measurements to height or recumbent length. Linear growth was more retarded in children with spastic quadriplegia than in those with less widespread spasticity, and there was a tendency for the older children to be more growth-retarded. Upper-arm and lower-leg lengths provided useful information about linear growth. Growth charts using these alternative measurements have been developed which can be used to assess linear growth of children with cerebral palsy when it is difficult or impossible to measure height or recumbent length because of joint contractures. These charts should improve the assessment of the nutritional status of children with cerebral palsy.
