M. Biceps Femoris Caput Breve

Biceps Femoris (Short Head) (BF Short L)

The M. Biceps Femoris Caput Breve (Biceps Femoris (Short Head)) is a muscle of the thigh posterior region. It is responsible for knee flexion, external rotation of the lower leg with flexed knee (single-joint - no influence on hip joint). 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).
