Abstract
Introduction: There is negative correlation between conduction velocities in both the Median sensory and Ulnar nerves and an individual's height, which likely accounts for the fact that, among most of the adult population, for each inch increase in height conduction velocities between the wrist and digits of an individual's hand decrease by 0.5 m/s. Consequence of it results in, impulse latencies within the Median, Ulnar, and Sural nerves increases with height. There is negative correlation between height and the amplitude of impulses in the sensory nerves. Functions of peripheral nerves and their parameters can be assessed by Nerve conduction studies (NCS). These parameters are known to vary with anthropometric measurements. Objective: To study the effect of height on the NCS variables in the median nerves of the limbs. Material and method: The study was conducted in 196 healthy individuals. The anthropometric parameters like height, weight and BMI were calculated. The compound muscle action potential (CMAP) and the sensory nerve action potential (SNAP) were recorded. Statistical analysis: The correlation of height with the median NCS variables were analysed by using Z test for two samples. Results: After the adjustment of other anthropometric factors, height (161.8673+8.140608) showed negative correlation with conduction velocities of median motor and sensory nerves of both the hands. Conclusion: Height showed a significant negative correlation with the median motor and sensory NCS parameters.
