This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Extensor Digitorum Longus Extensor Hallucis Longus
A group of muscles generally denotes muscles of the same function and may share a common attachment point. Foot Extensor
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.

They dorsiflex the foot (bring the toes towards the knees) and assist in eversion.

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 felt on the dorsum of the foot and extends almost to the tips of the middle three toes.  The digitorum longus may focus pain strongly at the ankle. The hallucis longus refers pain to the dorsum of the foot, especially the distal end of the first metatarsal and the base of the big toe.

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

A person with TrPs in the long extensors of the toes mostly complains of pain on the top of the foot extending to the “knuckles” of the foot.  Foot slap or weakness of the foot may also occur as well as night cramps of the extensors.  These muscles, in conjunction with other muscular changes, can produce hammer / claw toes..


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

  1. Pain that arises from the synovial joints of the tarsal bones

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

  1. Prolonged plantar flexion (toes pointed down).  Examples include sitting on a bar stool with the heels “hung” on the foot rest and the toes pointing towards the floor.
  2. Sleeping on the back with the toes pointed towards the foot of the bed due to tight bed sheets.
  3. Driving long distances while having the foot pointed to keep pressure on the accelerator.

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. Use cruise control while driving long distances and stop about every 60-90 minutes to stretch and walk around the car.
  2. Wear low heels to provide a natural angle at the ankle.
  3. Cease excessive jogging and weight bearing exercise while in therapy.  Other exercises that can be performed during this time include rowing, swimming, or bicycling.
  4. Place a pillow at the foot of the bed under the sheets so that the feet may rest against it to avoid plantar flexion.
