Vastus Lateralis (Vast Lat R)
The M. Vastus Lateralis (Vastus Lateralis) is a muscle of the thigh anterior region. It is responsible for knee extension, lateral patellar stabilization. This muscle is one of 26 with official SENIAM-recommended surface EMG electrode placement. This page documents the exact electrode position, anatomical attachments and a standardized test movement based on Hermens et al. (2000).

Knee extension in sitting against resistance
Common use cases for surface EMG measurement of the M. Vastus Lateralis:
2/3 on line from ASIS to the lateral patellar border. Orientation: 20 degrees to line ASIS-lateral patellar border. Based on the official SENIAM recommendations (Hermens et al. 2000).
Knee extension in sitting against resistance. This movement is part of the SENIAM protocol for standardized contraction verification.
Yes. The M. Vastus Lateralis is one of 26 muscles for which the SENIAM project has published official surface EMG electrode placement recommendations.
