Equations to predict length in children with neurological impairment (adapted from Haapala et al. [11])

Age 0–12 years (Stevenson 1995)	• Estimated height: = (2.68 x knee height) + 24.2 • Estimated height = (3.26 x tibia length) + 30.8
Age ≥ 7 years (Gauld et al. 2004)	• Estimated height = 2.423 knee height + 1.327 age + 21.818 (Males) • Estimated height = 2.758 tibia lenght + 1.717 age + 36.509 (Males) • Estimated height = 2.473 knee height + 1.187 age + 21.151 (Females) • Estimated height = 2.771tibia lenght + 1.457 age + 37.748 (Females)
