Nerve Conduction Study of Median Nerve in Normal Healthy Subjects with Different Age Group

Nerve conduction studies (NCS) are performed to diagnose the disorders of the peripheral nervous system. NCS reference values are used to define the limits of normal function and diagnose the various type of peripheral neuropathies with test values of outside the normal range. Degenerative changes occurring with ageing leads to decrease in nerve conduction velocity and amplitude. The values of NCS alter with ageing. Thus it is essential to have NCS reference values for different age group to increase the diagnostic value. In present study, Median nerve conduction study of motor and sensory parameters was done by Computerized NCV machine Neuro-MEPw on subjects who were grouped as 18–35 yrs and 36–60 yrs. Statistical study showed significant increase in latency, decreased velocity and amplitude in age group of 36–60 yrs. Correlation study showed negative correlation between nerve conduction velocity, amplitude and age.
