Dr. Erik Stålberg is Professor emeritus in Clinical Neurophysiology, Uppsala University. Together with J Ekstedt he developed the Single Fiber EMG method in the 1960-ties. After his PhD thesis on “Propagation velocity in Single muscle fibers” he joined the hospital EMG lab in Uppsala in 1967. He was chairman of the department 1993-2001. After retirement 2001 he continued in the lab with routine EDX work, research and teaching. The early years were filled with methodological struggle to prove that it was possible to make recordings from individual muscle fibers and to document the usefulness of SFEMG in the evaluation of nerve-muscle diseases. His interest in signal analysis of various signal types in the EMG lab continues through his career and he implemented computers in routine analysis of the EMG signal in the late 1970-ties. Stålberg developed a number of EMG methods in addition to SFEMG such as Macro EMG, Scanning EMG and quantitation of EMG and neurography. Through many publications, courses and lectures he has spread the message on how to implement useful diagnostic methods and how to optimize the value of EDX.
