Modeling peripheral nerve stimulation using magnetic fields.
The technique of magnetic stimulation (MS) has the potential to contribute to the study of the peripheral nervous system, but the uncertainty of the site of activation and problems in achieving supramaximal responses have prevented its extensive use. This paper discusses mathematical modeling of MS of the peripheral nerves. The work reveals recent theoretical advances, which may give new insight to the exact site of activation and help to understand the phenomena involved. The mechanisms of stimulation are examined: a solid comprehension of the stimulation event may boost new applications of the technique.
