Semimembranosus (Semimem L)
The M. Semimembranosus (Semimembranosus) 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 not covered by the official SENIAM catalogue — placement is based on established clinical literature. 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 internal rotation
This muscle has no SENIAM-standardized electrode position. Placement should be based on anatomical knowledge.
The electrode is placed — what next? easyEMG visualises muscle activity in real time, with SENIAM-compliant placement guidance, up to 4 channels at once and biofeedback training right afterwards.
In training, what matters for this muscle is targeted activation and left/right symmetry.
