ISEK-JEK Tutorials

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.

An introduction into the analysis of stabilizing feedback control of walking

Stable gait, defined as gait that does not lead to falls, requires control of the body center of mass relative to the base of support. Model studies suggest that this requires active, feedback control, especially in the mediolateral direction. In older adults and in individuals with neurological or orthopedic disorders that affect walking ability falls during gait are a common cause of injuries, hospitalization and loss of independence. In this tutorial, we will discuss how gait analysis can be used to assess impairments of stabilizing feedback control of gait. We will present methods ranging from those that require limited input data (e.g. position data of markers placed on the feet and pelvis only) and relatively simple analyses to those that require full-body kinematics and musculoskeletal modeling and we will discuss what information on feedback control can be gleaned from each of these.


Prof.dr. Jaap van Dieën

Department of Human Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam Movement Sciences

Jaap van Dieen is professor biomechanics and head of the department of Human Movement Sciences at the Vrije Universiteit Amsterdam. His research focuses on: 1) Control of posture and gait (with a focus on trunk control): how can control be assessed, what are the determinants of control quality, how is this affected by disorders, and how can it be improved?  2) Low-back loading: how can it be assessed and how can it be reduced? 3) Measurement tools for biomechanical and neurophysiological assessment for application outside the lab. Jaap van Dieën has successfully supervised over 60 PhD students and (co-) authored over 500 papers in international scientific journals. He is currently the editor in chief of the section Biomechanics and Control of Human Movement of Frontiers in Sports and Active Living and serves on several editorial boards

Dr. Maarten Afschrift

Department of Human Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam Movement Sciences.

Maarten Afschrift is an assistant professor at the department of Human Movement Sciences at the Vrije Universiteit Amsterdam. His research focuses on: 1) perturbation experiments and simulations to gain insight in human balance control and in the factors that limit balance control in elderly.  2) balance supporting control of wearable robotic devices. 3) Simulations of human movement to predict the effect of mechanical interventions, such as an exoskeleton, on human movement.

Dr. Sjoerd Bruijn

Department of Human Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam Movement Sciences.

Sjoerd Bruijn is an associate professor at the department of Human Movement Sciences at the Vrije Universiteit Amsterdam. His research focuses on how most humans can walk on two legs with such remarkable ease, and why pathology and ageing decrease this ability; in short, he studies “human gait stability”. In doing so, he tries to tackle 3 main questions; 1. How can we quantify gait stability properly? 2. How do humans achieve a stable gait pattern (what is the role of passive mechanics, what is the role of control? At which levels in the nervous system does control originate?), and 3. Can we apply the mechanisms we studied in the second question to help people with impaired gait stability? While he usually takes a more fundamental approach to these questions, he often collaborate with clinical partners.


Surface EMG detection in space and time, conditioning and pre-processing

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;

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, 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.
