Semitendinosus (Semiten R)
The M. Semitendinosus (Semitendinosus) is a muscle of the thigh posterior region. It is responsible for knee flexion, hip extension, internal rotation of the lower leg with flexed knee. 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 flexion, hip extension, internal rotation of the lower leg with flexed knee

Knee flexion in prone position against resistance with foot internal rotation
Common use cases for surface EMG measurement of the M. Semitendinosus:
50% on line between ischial tuberosity and medial epicondyle. Orientation: Parallel to line ischial tuberosity-medial epicondyle. Based on the official SENIAM recommendations (Hermens et al. 2000).
Knee flexion in prone position against resistance with foot internal rotation. This movement is part of the SENIAM protocol for standardized contraction verification.
Yes. The M. Semitendinosus is one of 26 muscles for which the SENIAM project has published official surface EMG electrode placement recommendations.
