Decoding the physiological signatures in EMG signals: free webinar

physiological signatures in EMG signals

Decoding the physiological signatures in (EMG) signals

Wednesday 29th May | 15.00 BST

When muscles contract they emit electrical signals that are picked up by Electromyography (EMG). The signals code many features of the physiological state and recruitment patterns of the muscles. This free webinar will explore the physiological signatures in EMG signals.

We are delighted to welcome Professor James Wakeling for this free webinar Decoding the physiological signatures in EMG signals which is in partnership with BASES. This presentation will consider how to use wavelet analysis and principal component techniques to decode this information from the EMG. EMG-derived patterns of recruitment and coordination will be discussed and implications for new muscle models will be considered as will the physiological signatures in EMG signals. 

Learning Outcomes of the Webinar

  • Describe features of muscle contraction that influence electrical properties of the EMG signal
  • Discuss how time-frequency characteristics of EMG can be quantified using principal component approaches
  • Outline how EMG-specific wavelet techniques can decompose EMG signals into time-frequency properties.
  • Explain how patterns of motor recruitment and muscle function can be determined using EMG

Presenter Profile – Professor James Wakeling

physiological signatures in EMG signals

Professor Wakeling has 25 years of experience studying high-performance function in muscles from both animal and human systems.

He currently leads a research laboratory in Simon Fraser University, Canada that develops novel approaches to EMG signal decomposition, image analysis techniques for diagnostic ultrasound and physiologically-realistic muscle models for musculoskeletal simulations.

Recent highlights include:

  • Demonstrating how motor recruitment patterns change with the mechanical demands of a movement.
  • How models are better able to predict muscle forces when they account for muscle fibre-type characteristics and their metabolic cost.
  • How deteriorations in muscle tissue with intramuscular fat cause reductions in the mechanical quality of contractions.

Q&A section

If you have any questions for Professor James Wakeling regarding physiological signatures in EMG signals there will be a 15 minute Q&A session at the end of his presentation. You can submit questions via the sign up page or during the webinar by typing them into the questions box.

Recording will be available

If you cannot make the live presentation, fear not the recording will be available on our website. If you are registered you will be sent a link to the recording, when available. Usually within 48 hours.

Hi, I'm Ryan, one of the bloggers here at Human Kinetics Europe Ltd. (If you want my official title, it's Marketing Executive.) I've always had a passion for health and fitness, having previously worked in gyms and played a variety of sports all my life. Now (as a somewhat of a washed-up athlete) I find myself working at the world’s biggest independent publisher of sport, health, dance and fitness resources. Which is amazing! Why? Because I get unrestricted access to all the best, most interesting, scientifically-proven writing on sports science. And what's more, I get to share it all with you!
