This paper presents the protocol of step by step elaboration of the nutritional program for the children presenting with traumatic brain disease during the period of clinical stabilization of its acute manifestations with special reference to the early rehabilitative measures. The main steps include the choice of the diet, the modes of its consumption, and dosing regimens based on the assessment of the nutritional status, energy expenditures, and the act of swallowing. Strong evidence of the beneficial effect of the nutritional support for the children in the persistent vegetative state is provided on condition that the standard mixtures for enteral nutrition are administered through a nasogastric tube or a gastrostomy tube. Indirect calorimetry has demonstrated low energy demand of the patients in the vegetative state, regardless of their age and the type of motor rehabilitation. It is concluded that active early rehabilitation is possible and necessary for the prevention of complications of hypodynamia and the maintenance of muscular mass in the children.
