Jitter Recordings with Concentric Needle Electrode

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.

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
