WebAbstract. Electrodiagnostic methods play important roles for the diagnosis and evaluation of ALS. They are useful for 1) the early establishment of the diagnosis, 2) the differential diagnosis, and 3) the quantitative evaluation of the progression. Needle electromyography reveals active neurogenic changes over the wide territories of the body. WebNeedle electromyography (EMG) complements nerve conduction studies and serves a crit-ical role in the evaluation of both muscle and nerve diseases. With experience, needle EMG can be rapidly performed and interpreted. However, to the uninitiated, the procedure can seem very complicated and the interpretation of the waveforms arbitrary. megan fox turtleneck
