Effect of Different Phases of Menstrual Cycle on Nerve Conduction Velocity: A Study from Central India

The study was done to find out the effect of different phases of menstrual cycle on the Nerve conduction velocity in females.50 normal menstruating women with age between 18 to 24 years, with regular menstrual cycle were randomly selected from the nearest nursing college hostel and were included in the study. Evoked electromyogram (EMG) was used to measure the nerve conduction velocity of median nerve in all the three phases of menstrual cycle i. e. proliferative, secretory and menstrual phase. Their mean values were calculated and compared in all the three phases. When the mean of nerve conduction velocities in different phases of menstrual cycle were compared, a decrease in the NCV was observed in the secretory phase as compared to the menstrual and proliferative phase but the p value was not significant. Nerve conduction velocity of the peripheral nerves does not vary significantly during the different phases of the menstrual cycle. However these parameters should be kept in mind while conducting studies on nerve conduction velocities.
