1. Krick method Kcal/day = (BMR x muscle tone factor x activity factor) + growth factor BMR basal metabolic rate (kcal/day) = body surface area (m ^{2}) x standard metabolic rate (kcal/m^{2}/h) x 24 hMuscle tone factor: 0.9 if decreased, 1.0 if normal, 1.1 if increased Activity factor : 1.15 if bedridden, 1.2 if dependant, 1.25 if crawling, 1.3 if ambulatory Growth factor : 5 kcal/g of desired weight gain | |

2. Height-based method
14.7 cal/cm in children with motor dysfunction 13.9 cal/cm in ambulatory patients with motor dysfunction 11.1 cal/cm in non-ambulatory patients | |

3. Resting energy expenditure-based method 1.1 x measured resting energy expenditure |
