ISEK is pleased to announce the novel ISEK- JEK Tutorials, a series of online events starting in Summer 2021. The ISEK- JEK Tutorials are based on tutorial papers published in the Journal of Electrophysiology and Kinesiology (JEK).
They are intended for students to provide technical background on some fundamental topics in Electrophysiology and Kinesiology research, and most importantly, to answer questions that trainees might have on these topics.
Each event in this series will consist of 90 minutes of live presentations and Q&A periods.
ISEK Tutorials will be recorded and available on the website.
There are no fees to participate in the ISEK – JEK Tutorials, but you must register to participate.

Surface EMG detection in space and time, conditioning and pre-processing
Tuesday, July 20 at 1:00pm- UTC
This webinar is oriented to non-engineers and is based on the first two Tutorials published in the Journal of Electromyography and Kinesiology concerning surface EMG:
Merletti R., Muceli S., Tutorial. Surface EMG detection in space and time: best practices. Journ. of Electromyogr. and Kinesiol., 2019; 49:doi.org/10.1016/j.jelekin.2019.102363
Merletti R., Cerone G.L. Tutorial. Surface EMG detection, conditioning and pre-processing: best practices, Journ. of Electromyogr. and Kinesiol., 2020;
54 102440, doi:10.1016/j.jelekin.2020.102440
A short introduction describes the barriers to the widespread use of sEMG, as addressed in the Frontiers project https://www.frontiersin.org/research-topics/11157, and the need to overcome them.
The lecture of Dr. Muceli addresses the best practices concerning sEMG electrode geometry and location. The lecture of Dr Cerone addresses the best practices concerning amplification, filtering and conditioning of the raw sEMG signal. Both lectures provide a simple technical bases for proper sEMG detection and recording by clinical operators.
- The potential of sEMG observation and measurements for rehabilitation operators
- The need for teaching rehabilitation operators about sEMG
- The results of the Frontiers Project on barriers to clinical use of sEMG
- Future perspectives (large HDsEMG systems covering a limb)
- The surface EMG image and its sampling with an electrode pair or an electrode grid
- The averaging (low pass filtering) effect of the electrode area
- The propagation of Motor Unit action potentials
- End-of-fiber effect and crosstalk
Discussion: 10 min
Giacinto Luigi Cerone
- The coupling between body-electrodes and biopotential amplifiers. Rejection of power line interference and relevance of Wireless Systems
- The importance of skin treatment to lower impedances and artifacts
- Conditioning of sEMG signals. Concept of filter (low pass, high pass, notch)
- Artifacts in the EMG recoding
- Concept of sampling and conversion into binary numbers.
Discussion: 10 min
