Brooks GMFCS Level II

Weight, height and BMI in cerebral palsy, walks with limitations

About this calculator

Percentiles and z-score for weight, height and BMI of children and adolescents with cerebral palsy of GMFCS Level II (walks with limitations) according to the growth curves of Brooks 2011 (2–20 years). The curves describe how children at this functional level actually grow – they are not a target; the authors identify weights below P20 as associated with increased morbidity and mortality.

In preterm infants, if a gestational age is given, age is corrected up to month 24 of life for the missing weeks up to 40+0. The z-score (SDS) describes the deviation from the median in standard deviations; the percentile the proportion of the reference population with a smaller value.
