This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Peroneus Longus
Peroneus Brevis
Peroneus Tertius
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.

Plantar flex (point the foot) and pronation of the foot.

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

The longus and brevis refer pain primarily to the lateral malleolus of   the ankle (outside ankle bone) as well as above, behind, and below it. The tertius refers pain to the anterolateral (front/outside) aspect of the lateral malleolus to the lateral heel.

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

A person with TrPs in the Peroneal muscles will not just complain of pain in the outside ankle and feet, but of weak ankles as well. The weakness in the ankles can cause a person to fall and be more prone to sprains. The weakness will make a person unable to ice skate or keep balance on a balance beam.

   

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

  1. Entrapment of the deep peroneal nerve.
  2. Lateral compartment syndrome.
  3. Ankle sprain.
  4. Muscle and tendon rupture.

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

  1. A fall that involves a twisting action at the ankle.
  2. Prolonged immobility from a cast.
  3. Morton foot structure.
  4. Chronic tension in the tibialis anterior.
  5. Sleeping with the foot strongly plantar flexed.
  6. Wearing high heel shoes.
  7. Unsupported arches in those with flat feet.
  8. Tight elastic top of a long sock can compress the muscle.

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. Correct Morton foot structure.
  2. Discard any shoes that fit too tight and purchase shoes that are comfortable with adequate arch support.
  3. Avoid high heels and spike heels.
  4. Walk/jog on flat surfaces to ease strain on these muscles.
