TIBIALIS POSTERIOR

• Origin

Interosseous membrane, posterior surface of tibia and fibula

• Insertion

Navicular, cuneiforms, cuboid, and bases of 2nd, 3rd, and 4th metatarsals

• Agonist(s)

- Gastrocnemius

- Soleus

- Flexor digitorum longus

- Flexor hallucis longus

• Antagonist(s)

- Fibularis longus

- Fibularis brevis

• Function

Ankle inversion, ankle plantar flexion, ankle adduction, supports the arch of the foot

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 inside of the ankle and foot.

It can cause aching or burning sensations along the inside of the ankle and arch of the foot, and sometimes discomfort in the heel.

• Potential Causes

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

• Excessive strain during activities that require stabilizing the foot and ankle.

• Poor footwear or improper biomechanics during activities.

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

• Muscle imbalances between the tibialis posterior and other lower leg muscles.

• Prevention Tips

• Use proper techniques and footwear during activities involving inversion and plantar flexion of the foot to avoid overloading the tibialis posterior.

• 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.
