SENIAM recommended Lower Leg Right

M. Fibularis Longus

Fibularis Longus (Fib Long R)

The M. Fibularis Longus (Fibularis Longus) is a muscle of the lower leg region. It is responsible for eversion (pronation) at the subtalar joint, plantar flexion, stabilization of the transverse arch of the foot. 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).

Frequently Asked Questions

Where do I place the EMG electrode on the M. Fibularis Longus?

25% on line from fibular head to lateral malleolus. Orientation: Parallel to the fibula. Based on the official SENIAM recommendations (Hermens et al. 2000).

Which test movement activates the M. Fibularis Longus?

Foot eversion against resistance. This movement is part of the SENIAM protocol for standardized contraction verification.
