To Assess Nerve Conduction Velocity Declination Rate of Ulnar Nerve According to Age in Healthy Population

Abstract

Background: Normal ageing is a global biological change that occurs with age and is unaffected by diseases that have a negative impact on the clinic. According to research, ageing changes the architecture, structural characteristics, and function of the peripheral nervous system. Myelinated and unmyelinated nerve fibers are significantly reduced. There is a well-documented effect on peripheral nervous system function and electrophysiological characteristics. Nerve conduction velocity, muscle strength discrimination, autonomic reflexes, and endoneurial blood flow are all affected. Conduction velocity declinations may occur at 30-40 years of age, however the values usually shift by less than 10m/s by the sixth or even eighth decade. Aim and Objective: newline1) To evaluate the Motor and Sensory nerve conduction velocity of Ulnar Nerve according to age in both genders 2) To find the declination rate of Motor and Sensory nerve ulnar nerve according to age in both genders newlineMaterial and Method 120 healthy subjects having the ages of 31-70 were included in this study, divided into five age groups. Subjects suffer from metabolic, traumatic or nervous disorders affecting the ulnar nerves were excluded. Ulnar Nerve conduction Velocity was evaluated. Results: A significant statistical decrease was found in the nerve conduction velocity of the ulnar nerve with increasing age, after analyzing the data with SPSS version twenty six.Aging causes an increase in the latency of the Ulnar Motor Nerve and the Ulnar Sensory Nerve. The amplitude, motor and sensory conduction velocity of the ulnar nerves decline significantly with age in all age groups and both genders. MNCV declination rate was 2.72 m/s per decade in females aged 31-70 years, while SNCV declination rate was 3.58 m/s per decade.
