Lori S, et al. - The evolution of sensory-motor nerves in the upper and lower limbs was comprehensively analyzed in neurologically healthy preterm infants. Using sensory-motor studies, researchers also compared the rate of maturation in preterm infants at term age and full-term healthy neonates. The study cohort consisted of neurologically normal preterm infants born at 23–33 weeks of gestational age, who underwent sensory nerve conduction and motor nerve conduction studies from plantar medial and median nerves and from tibial and ulnar nerves, respectively. It was determined that the sensory-motor conduction parameters exhibited a clear association with gestational age. However, extrauterine life did not exert an impact on the maturation of the peripheral nervous system in the very preterm babies who were neurologically healthy.
