Fibularis Brevis (Fib Brev R)
The M. Fibularis Brevis (Fibularis Brevis) is a muscle of the lower leg region. It is responsible for eversion (pronation) at the subtalar joint, weak plantar flexion. 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).
Eversion (pronation) at the subtalar joint, weak plantar flexion
At 25% of the line from the tip of the lateral malleolus to the fibula head, anterior to the peroneus longus tendon
Orientation: Along the line from the lateral malleolus to the fibula head, 20 mm inter-electrode distance

Foot eversion against resistance
Common use cases for surface EMG measurement of the M. Fibularis Brevis:
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.

Foot eversion against resistance. This movement is part of the SENIAM protocol for standardized contraction verification.
Yes. The M. Fibularis Brevis is one of 26 muscles for which the SENIAM project has published official surface EMG electrode placement recommendations.
