Motor nerve conduction velocity & Hoffman's reflex latency in newborns.

Abstract

A total of 72 newborns and their mothers were studied to assess the influence of various variables on the motor nerve conduction velocity (MNCV) and Hoffman's reflex latency (H-RL) of the babies with a view to differentiate fullterm and preterm low birth weight babies. MNCV were significantly lower and H-RL significantly higher in preterm appropriate for gestational (PT-AGA) age babies compared to fullterm appropriate for gestational age (FT-AGA) and fullterm intrauterine growth retarded babies (FT-IUGR). In FT-IUGR babies, only MNCV was significantly reduced as compared to FT-AGA babies.
