title: [Neuromuscular status of children of different gestational age on the stage of transition from intrauterine immersion to the earth's gravity].
abstract: The work was aimed at describing the neuromuscular status of premature baby in the context of the ontogenetic and zero gravity model using the results of superficial interference electromyography (IEMG). Throughout six postnatal weeks, IEMG of premature babies is similar to EMG of full-term child on the first days of extrauterine life; IEMG is characterized by a "simplified" temporal structure, low amplitude and frequency, IEMG dynamics of fullterm child is slow in contrast to premature baby; the reason seems to be maximum long intrauterine life during which the motor system gets better prepared and maturates. On the other hand, complexity and high amplitude of premature baby IEMG as compared with full-term child of the same postconceptual age are associated with the inevitable sensory stimulation after birth. Abilitation procedures provided to premature baby could be adapted to the purposes of post-flight rehabilitation of cosmonauts.
