Overview

Overview of EMG Methodology

A brief overview of the EMG methodology used in this workshop.

You can download a PDF of all the EMG images.

Workshop Video

The methodology used in this workshop for the collection of the raw data is covered in the EMG workshop video. The video should be viewed in conjunction with the workshop notes as it does not, by itself, provide a complete overview of the workshop.

Results and analysis

View the EMG results and some further comments on the analysis of this data.

Workshop assessment tasks

Readings

All students must read Öhman (1967) before attempting this workshop. This paper is essential reading and is the pioneering work in this field. Students might also optionally read Öhman, Leanderson and Persson (1965), a preliminary study which established some of the methodology for the 1967 study. Students are also strongly advised to read the relevant section in the Hardcastle (1976) reference.

The following Öhman readings are available in the password protected location that is communicated to registered students at the start of the semester. All QPSR reports are available from the KTH website.

Öhman, S., Leanderson, R., & Persson, A., "Electromyographic studies of facial muscles during speech", QPSR 3/1965.

Öhman, S., "Peripheral motor commands in labial articulation", QPSR 4/1967.
