Evaluationof Motor NCS Parameters between Upper and Lower Limbs and Their Pattern of Maturation in Infants and Children
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 1
Abstract
Peripheral nervous system (PNS) development plays a crucial role for normal motor performance of the child. Maturation of PNS starts before birth and continues till 5 to 6 years of age. Evolution of Peripheral motor nerves as detected by different Nerve Conduction Study (NCS) parameters are different for upper and lower limbs and also varies according to different motor nerves irrespective of extremity. Our aim was to evaluate howmuch the peripheral motor nerve NCS parameters differed from upper versus lower limbs and their pattern of maturation from birth to 6 years of age. For this a cross-sectional prospective study was undertaken on 63 normal infants and children in the department of Physiology of I.P.G.M. E & R in collaboration with paediatrics department of the same institute and Bangur Institute of Neurology, Kolkata. Compound Muscle Action Potential (CMAP) amplitude and Motor Nerve Conduction Velocity(MNCV) of Median, Ulnar, Tibial and Peroneal nerves were measured and results were analyzed by using SPSS version 20. It was seen that motor NCS parameters varied significantly between upper and lower limbs and also their pattern of maturation towards adult normal values from birth to 6 years of age varied for different motor nerves as depicted by means plot.Tibial was the first motor nerve and Peroneal was the last to attain normal adult values among the nerves. Thus motor NCS parameters not only varies from upper and lower limbs but also their progression towards adult normal values differed from one to another.
