Electrical injury is known to alter the normal physiological function of nerves. In most cases, the change in function is only minor, but in severe instances the physiological function may be lost entirely. The changes in function involve the ability of the nerve to transmit an impulse, which is a function of the nerve's ability to create and maintain an electrical gradient across its membrane. When the nerve is exposed to an electrical current, the ability to maintain an electrical gradient across the membrane is reduced or lost. This change may be transient or permanent. The changes in the gradient hinder the nerve from propagating the impulse, which is the means of information transfer to and from the CNS (central nervous system). Due to the manner in which human victims are typically exposed to an electric shock, the peripheral axons usually display the greatest change in physiological function.

A dissertation submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in ful lment of the requirements for the degree of Master of Science in Engineering. Johannesburg, 2015 / This research investigates the e ects of the frequency components of the lightning First Short Stroke (FSS) on the current pathway through human tissues using frequency domain analysis. A Double Exponential Function (DEF) is developed to model the FSS with frequency components in the range 10 Hz 100 kHz. Human tissues are simulated using Finite Element Analysis (FEA) in COMSOL and comprises of two types of models: Single Layer Cylindrical Model (SLCM) and Multi-layered Cylindrical Model (MLCM). The SLCM models 54 human tissues independently and the MLCM models the human leg with ve tissue layers: bone marrow, cortical bone, muscle, blood and fat. Three aspects are analysed: current density, complex impedance and power dissipation. From the SLCM results, aqueous tissues have the lowest impedances and tissue heat dissipation is proportional to tissue impedance. Results from the MLCM show that 85% of the FSS current ows through muscle, 11% ows through blood, 3:5% through fat and the rest through cortical bone and bone marrow. From the results, frequency dependent equivalent circuit models consisting of resistors and capacitors connected in series are proposed. The simulation results are correlated with three main clinical symptoms of lightning injuries: neurological, cardiovascular and external burns. The results of this work are applicable to the analysis of High Voltage (HV) injuries at power frequencies. / MT2017
