FIBULARIS BREVIS

• Origin

Lateral tibial condyle, head and lower part of fibula

• Insertion

Base of fifth metatarsal

• Agonist(s)

- Tibialis anterior

- Tibialis posterior

- Gastrocnemius

- Soleus

• Antagonist(s)

- Tibialis anterior

- Peroneus tertius

• Function

Ankle eversion, ankle plantar flexion, ankle abduction

TRIGGER POINT(S)

• Location

Trigger points can be found along the length of the muscle, particularly in the mid to lower portion.

• Pain Referral Pattern

Pain may refer to the lateral side of the lower leg and foot.

It can cause aching or burning sensations along the outside of the ankle, and sometimes discomfort in the lateral part of the foot.

• Potential Causes

• Overuse or repetitive activities involving eversion and plantar flexion of the foot, such as walking, running, or jumping.

• Excessive strain during activities that require stabilizing the foot and ankle, especially on uneven surfaces.

• Poor footwear or improper biomechanics during activities.

• Trauma or injury to the lateral side of the lower leg and foot.

• Muscle imbalances between the fibularis brevis and other lower leg muscles.

• Prevention Tips

• Use proper techniques and footwear during activities involving eversion and plantar flexion of the foot to avoid overloading the fibularis brevis.

• Incorporate regular stretching and strengthening exercises for the lower leg muscles.

• Ensure proper warm-up and cooldown routines before and after exercise.

• Gradually increase workout intensity to avoid sudden strain.

• Ensure balanced strength training to avoid muscle imbalances.
