Professor Erik Stålberg, M.D., Ph.D.

Prof. Stalberg is a Professor Emeritus at the Uppsala University where he has spent his lifetime to learning, teaching, research and patient care. He is internationally recognized for his contributions to electrodiagnostic medicine. He pioneered the technique of single fiber EMG, and also other methods of quantitative analysis. He has promoted quantitative analysis and tele-medicine. He has trained many luminaries in this field. He has published over 450 articles, written chapters in many text books, and co-authored the book ‘Single Fiber EMG’. He has lectured in many countries and conferences where he has been showered with recognition and awards. Among them, American Association of Neuromuscular and Electrodiagnostic Medicine gave him the “Distinguished Researcher Award” and “Lifetime Achievement Award”.

Description: 
Jitter recordings using concentric needle electrodes is replacing recordings with original SFMEG electrodes. This is challenging because of the risk of obtaining signals generated by more than one fiber per spike. New criteria for acceptance will be described as well as new instrument settings and certain quality problems in time measurements.

Learning objectives: 

  • The lecture will focus on practical details in CNE jitter recording 
  • Differences in CNE and classic SFEMG will be highlighted
  • Electrodes, filter settings, pitfalls in measurements will be discussed
  • Reference CNE jitter values from a multicenter study will be presented
  • Both voluntary and stimulation activation will be described
