This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Tibialis Anterior
A group of muscles generally denotes muscles of the same function and may share a common attachment point. Foot Flexor
Muscle function, in this definition, is what the muscle could do if it was to contract by itself with the body in anatomical position.  This is a general definition of muscle function.  For more information on how muscles work together on the body please refer to a physiology or functional anatomy text.

The tibialis anterior dorsiflexes the ankle (pulls the foot towards the head).                       

A description of where a Myofascial Trigger Point may produce pain in the body.  This area is generally located away from the trigger point.

Pain is referred to the anteromedial (front / middle) aspect of the ankle as well as the pain in the great toe. Pain may also be felt down the front of the shin.

A description of the symptoms a person may experience with trigger points in the muscle being described.

A person with TrPs in the tibialis anterior will complain of pain over the anteromedial aspect of the ankle and in the great toe. Other symptoms include weakness in dorsiflexion movement as well as drop foot that causes tripping as well as weakness in the ankle. A person will not usually complain of nocturnal pain. Pain from TrPs in the tibialis anterior muscle usually occur in conjuction with TrPs in other muscles.


 A list of possible diseases that fit the information derived from examination of a patient.

  1. TrPs in other extensors of the foot and toes as well as the peroneus tertius.
  2. L5 radiculopathy.
  3. Anterior compartment syndrome.
  4. Herniation of the tibialis anterior muscle

A list of activities or positions that may either CAUSE a trigger point to manifest or PROLONG a pain condition respectively.

  1. Usually TrPs in the tibialis anterior are activated more by gross trauma rather than overuse, but may be activated by walking on slanted surfaces such as the edge of a crowned road.
  2. Tension of the calf muscles can strain the tibialis anterior by keeping it on an eccentric contraction.
  3. Morton foot structure.

A corrective action is usually a modification of daily routine which will reduce stress on the affected muscle(s) in a person with myofascial trigger points.

  1. Walk on even surfaces and avoid slanted ones.
  2. Relieve the tension in the calf muscles if it exists.
  3. Have the Morton foot structure corrected with the proper orthotics to relieve tension and restore balance to the foot.
