Surface Electromyography of the Masticatory Muscles

This video introduces the use of surface electromyography (sEMG) for examining the facial muscles during eating, carried out at the Institute of Food Research, Norwich, UK, http://www.ifr.ac.uk, in the Bioinformatics and Statistics Group, http://www.ifr.ac.uk/Bioinformatics/index.htm.

An open access article giving a detailed treatment of some of the data presented here can be found at http://www.intechopen.com/articles/show/title/relating-surface-electromyogram...

Electromyograms are recordings of the small electrical signals generated by muscle movement, and EMG is often used to diagnose injuries or other pathologies affecting muscle activity. Our interest has been in using EMG to study the activity and function of healthy volunteers during eating. Electromyograms contain information that can be related to the physical properties of the foods being consumed, and also to sensory evaluations made by the volunteer whilst eating. Thus, EMG may provide an explanatory link between measurements of texture made using instrumentation, and evaluations of texture as experienced by the consumer.
