M. Flexor Digitorum Longus

Flexor Digitorum Longus (FDL L)

The M. Flexor Digitorum Longus (Flexor Digitorum Longus) is a muscle of the lower leg region. It is responsible for flexion of toes II-V (distal joints), ankle plantar flexion, inversion, support of the longitudinal arch. 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).
