The aim of this study is to build an experimental scanning EMG system in order to reveal the significant differences in either length of cross-section of motor units (MU) or maximum amplitude between the subjects with juvenile myoclonic epilepsy and the healthy volunteers. Data obtained from the biceps brachialis muscles of the subjects were used to construct 3-D electrophysiogical maps of the motor unit territories through a M-File subroutine created in MATLAB 7.2. These maps were used to compute the length of cross-section of MUs either JME subjects or those of normal control (NC) and spinal muscular atrophy (SMA) group and to compare the groups in order to investigate the presence of the statistically significant differences between these groups in terms of length of cross-section of MUs and their maximum amplitudes. ©2009 IEEE. 2009 14th National Biomedical Engineering Meeting, BIYOMUT 2009 -- 20 May 2009 through 22 May 2009 -- Balcova, Izmir -- 77541

Scanning EMG is a method developed for examining the electro-physiological cross section and the size of the motor unit of a human muscle. Electrical specifications of the motor unit can be obtained as well as anatomical distribution of muscle fibers and pathological changes between different muscles can be examined by the help of this method. In this paper; an automation system which is designed for the execution of scanning EMG method, whether manually or automatically, and a user-interface are described. Parameters like step count and step size which are about the movement of an electrode, moved by a linear actuator, through muscle fibers can be defined as reference by user via designed interface. As a result, acquired signals are digitalized by data-acquisition card (DAQ) and saved as text file for the future signal process tasks. ©2009 IEEE. 2009 14th National Biomedical Engineering Meeting, BIYOMUT 2009 -- 20 May 2009 through 22 May 2009 -- Balcova, Izmir -- 77541
