INFLUENCE OF BODY TEMPERATURE TO NERVE CONDUCTION VELOCITY

Abstract:
The distribution of the conduction velocity (DCV) in peripheral nerve fibers is an important parameter in assessing the condition of nerve fibers during the clinical evaluation of the peripheral nerves. We reported a new method of estimating DCV by using regularized-non-negative-least squares and Fibonacci search for conduction length. Giving supramaximal electrical stimulation at two different sites, we recorded compound action potentials at another site. With the method we estimated DCVs, single fiber action potentials (SFAPs), and the distances between stimulation and recording sites. This method was applied clinically focusing on the effects of body temperature on DCVs and SFAPs. Differences in the effects of temperature were found between the slow and fast conduction components of nerves.
