abstract

  • Magnetic nerve stimulation is a non-invasive method of exciting a neural tissue which can be achieved by exposing the body to a transient magnetic field. This field is generated by passing a high current through a coil over a short period of time. By positioning this coil in a specific orientation over the targeted nerve, the time variation of the magnetic field will create an electric field in the conductive milieu of the body. Induced currents will result from that electric field. If those currents reach a certain amplitude within a specific time period this will cause a neural depolarization. This depolarization will enable us to test and examine the excited nerve which will provide us with the necessary data for an effective treatment. In my thesis I will analyse the benefits of magnetic nerve stimulation with the objective of designing a coil that provides a focussed magnetic field. This field will excite the targeted nerve with minimal or to no excitation to the surrounding nerves. This means that we can effectively apply or measure the excitation of the targeted nerve without involving the surrounding nerves. It is my intention to bring this application to a practical platform where a simple circuit with lower power requirements can be used. This will enable some patients requiring physiotherapy to safely administer magnetic nerve stimulation to themselves without the help of a therapist.
