(28) The most important muscles that prevent inversion ankle sprains are the two muscles located on the lateral side of the lower leg: the peroneus longus
and peroneus brevis.
The lateral compartment contains the peroneus longus
and peroneus brevis muscles and the superficial branch of the common peroneal nerve.

The degree of plantar flexion and the involvement of the peroneus longus
, soleus, gastrocnemius, and abductor hallucis muscles were analyzed.
The peroneal tendons, peroneus longus
and brevis, run in a sheath posterior to the lateral malleolus coursing beneath the superior and inferior retinacula.
In the electromyography (EMG), abnormal spontaneous activity and a reduced recruitment pattern of right tibialis anterior, peroneus longus
, and biceps femoris muscles were detected.
Needle electromyography (EMG) showed marked denervation potentials and a reduced recruitment pattern especially in the right tibialis anterior, peroneus longus
and biceps femoris muscles.
Needle EMG showed abnormal spontaneous activity at rest (positive sharp waves and fibrillation potentials) together with large amplitude motor unit potentials (MUPs) and reduced recruitment in right tibialis anterior, gastrocnemius, soleus, peroneus longus
, and vastus lateralis.
These muscles are also commonly referred to, respectively, as peroneus brevis and peroneus longus
. In this work we follow Standring (2016) in using fibularis instead of peroneus.
Lesions detected by magnetic resonance imaging (MRI) showed signal changes in heterogeneous character which they were hypointense on the T1-weighted sequences and hyperintense on T2-weighted sequences, also had intense contrast enhancement, where starting from the middle part of the tibial level in the area extending from proximal to distal medullary and muscles that are located adjacent to this area as tibialis anterior (TA), extensor hallucis longus (EHL), extensor digitorum longus (EDL), peroneus longus
(PL), and as more less tibialis posterior (TP), gastrocnemius (GC) in MRI (Figure 1).
The dependent variables included time-to-stabilization (TTS) after a forward hop, peak and mean activity of the tibialis anterior (TA), peroneus longus
(PL), and lateral gastrocnemius (LG) muscles, and antero-posterior (AP) and inversion-eversion (IE) ankle joint laxity.
