[The motor adaptation syndrome in the human fetus and its dynamics in newborns]
The authors describe a new syndrome characteristic of neonates born in the breech presentation. The syndrome, most evident upon the delivery, was observed in 30 infants, followed up in 20 of them. The neonates have specific lower limb position (maximally flexed thighs, extended, legs, slightly bent in the soles feet), spontaneous movements of the legs and feet are restrained, muscular tonicity reduced in the leg flexors and sole muscles is high in femoral flexors, the Achilles reflex is inhibited, motor response to plantar stimulation is weak or absent. Within day 3-7 of life the syndrome usually undergoes involution. The observed syndrome develops in the fetus as adaptation to abnormal lower limb position and hypokinesia.
