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).

Anatomy

Origin Fibular head, proximal 2/3 of the lateral fibular surface Insertion Medial cuneiform (plantar), base of the 1st metatarsal (plantar)

Test Movement

Foot eversion against resistance

Clinical Applications

Common use cases for surface EMG measurement of the M. Fibularis Longus:

Measure M. Fibularis Longus activity live

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 screening, this muscle is usually recorded together with its synergists — running several channels in parallel saves the most time.

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.

Is the M. Fibularis Longus a SENIAM-recommended muscle?

Yes. The M. Fibularis Longus is one of 26 muscles for which the SENIAM project has published official surface EMG electrode placement recommendations.
