The purpose of the current study is to evaluate the correlation between anthropometric measurement (weight, height and BMI) and balance in children with cerebral palsy.

• The European Society for Clinical Nutrition and Metabolism has pointed out that under-nutrition can led to change in body composition (e.g. depletion of body fat mass) and diminished function and outcome.
• The prevalence of under-nutrition in children with CP varies from 3.9 per cent to 71 percent mainly depending on the method of assessment, the severity of motor involvement and feeding problems.
• Studies indicate that children and adults with both mild and severe forms of CP have postural impairments. Dysfunctional posture control interferes with the activities of daily life .
• Children with CP may have impaired muscle tone and abnormal postural control, both of which affect functional balance capacity.
• There were associations between excess body weight and values below normal in some balance conditions, indicating that the anthropometric indicators interfered in the children's postural balance.

Knowledge of anthropometric measurements and whether they affect balance in children with CP will help clinicians to develop treatment programs which in turn will improve the overall balance and functional abilities of children with CP.

• Childeren age will be ranged from 8-12 years and on level Ⅰ and Ⅱ on Growth Motor Function Classification System
• Weight would be obtained on a digital scale (UNISCALE )
• Standing height was measured using a stadiometer with a fixed vertical backboard and an adjustable head piece.
• CDC 2000 charts will be used to measure BMI
• The Biodex balance system will be used for the assessment of static and dynamic balance of all children
