Relation of conduction velocity of peripheral nerves to body mass index in right handed and left handed subjects
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2017, Vol 4, Issue 1
Abstract
Background and Objectives: In the past few decades, major changes have taken place in the field of peripheral nerve studies especially in the relation to its ultrastructure, histochemistry, neurophysiology and axonal transport system. Wide spread interest in disorders of peripheral nervous system, which has emerged in recent years and introduction of various new investigating techniques like nerve conduction studies. The objective of present study was to assess the relation of body mass index to median nerve conduction velocity in right and left handed subjects. Methods: Hundred healthy individuals (50 right handed and 50 left handed) in the age group of 18-24 years were included in the study. The body weight of the subjects was measured using a pedestal type of weighing scale with a maximum capacity of 150 kg. The body weight was considered to the nearest of 0.1 kg. Height without footwear was measured using a vertical scale (Avery, India) with an accuracy 0.5 cm and was rounded to the nearest 0.01 m. Body Mass Index (BMI) was calculated from Height and weight. Median nerve conduction velocity was measured using Computerized Nerve Conduction Velocity Equipment (NeurocareTM-2000 manufactured by BiotechTM), Mumbai, India. Result: The mean age of the right handed subjects was 22.28 ± 1.97 and 22.7 ± 1.66 in left handed subjects involved in the study. The mean height of right handed subjects was 160 ± 11.54 and 161.92 ± 13.03 in left handed subjects. Mean weight of right handed subjects was 57.76 ± 12.02 and 60.66 ± 15.69 in left handed subjects. Mean body mass index of right handed subjects was 23.36 ± 4.23 and 22.54 ± 4.32 in left handed subjects. A negative correlation was seen with BMI and median NCV in right handed subjects for right median nerve (r = - 0.334, p<0.05) and left median nerve (r = -0.406, p<0.05). A negative correlation was seen with BMI and median NCV in left handed subjects for right median nerve (r = -0.314, p<0.05) and left median nerve (r = -0.406, p <0.05). Conclusion: In conclusion, BMI can affect the conduction velocities. We observed reduction in conduction velocities of the median nerve in right handed and left handed subjects with respect to body mass index.
