TRIGGER POINT(S)

• Location

Trigger points in the extensor hallucis longus muscle are typically located in the muscle belly, which runs down the front of the lower leg.

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

• Pain Referral Pattern

Pain from extensor hallucis longus trigger points may refer to the front of the lower leg and foot, particularly focusing on the big toe. 

It can cause aching or burning sensations in the shin area and sometimes discomfort in the top of the foot and big toe.

• Potential Causes

• Overuse or repetitive activities involving dorsiflexion of the foot, such as walking, running, or jumping.

• Excessive strain during activities that require lifting the big toe or extending the foot.

• Trauma or injury to the front of the lower leg.

• Muscle imbalances between the extensor hallucis longus and other lower leg muscles.

• Prevention Tips

• Use proper techniques and footwear during activities involving dorsiflexion of the foot to avoid overloading the extensor hallucis longus.

• 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.
