SOLEUS

• Origin

Upper third of the fibula and the soleal line of the tibia

• Insertion

Calcaneus via the Achilles tendon

• Agonist(s)

- Gastrocnemius

- Plantaris

• Antagonist(s)

- Tibialis anterior

- Extensor digitorum longus

• Function

Plantarflexion of the foot (pointing toes downward)

TRIGGER POINT(S)

• Location

Trigger points can be found along the length of the muscle, particularly in the middle and lower portions

• Pain Referral Pattern

Pain may refer to the posterior calf, the Achilles tendon, and sometimes down to the heel and the bottom of the foot.

It can cause aching, burning, or sharp pain in the calf, and may contribute to discomfort or restricted movement in the ankle and foot.

• Potential Causes

• Overuse or repetitive activities involving plantar flexion, such as running, walking, or certain sports.

• Poor footwear or improper foot mechanics.

• Muscle imbalances between the soleus and other lower leg muscles.

• Prolonged standing or sedentary lifestyle.

• Trauma or injury to the calf or Achilles tendon.

• Prevention Tips

• Use proper techniques and form during activities involving plantar flexion to avoid overloading the soleus.

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

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

• Maintain good posture and ergonomics during daily activities.

• Wear appropriate footwear that provides good support and fit to avoid muscle strain.

• Avoid prolonged periods of standing without movement.
