Investigation of the effect of fiber diameter variability via recording from tendon via of single fiber electromyography

In this preliminary study,two muscle fibers which one of them had a constant fiber diameter and the other had a variable fiber diameter were created by using an EMG simulator. Single Muscle Fiber Action Potentials (SMFAPs) were recorded either from the vicinity of the neuromuscular junction or near the tendon. It was intended to reveal the relationship between the time dispersions of these electrical activities and the differences of muscle fiber diameters. Hence it is considered that the the difference between the diameters of muscle fibers contributing to these electrical activities can be estimated.
