Electrophysiological studies (MNCV and H-RL) in twin babies

Abstract

Twenty-six fullterm and eight preterm babies born of twin pregnancies were studied. Offsprings were subjected to measurements of weight, crown heel length and head circumference along with motor nerve conduction velocity (MNCV) and H-reflex latency (H-RL) at right median nerve. The preterm twins had significantly lower MNCV and higher H-RL. The electrophysiological parameters did not vary in first and second born twins as well as in heavier and lighter twins. Three pairs of twins were available for follow-up study.
