This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Tibialis Posterior
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 posterior functions as an inverter of the foot and assists in plantar flexion 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.

Pain is felt over the Achilles tendon above the heel.

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

A person with TrPs in the tibialis posterior is likely to complain of pain while walking or running. Pain is generally felt in the sole of the foot and Achilles tendon and sometimes, though to a lesser degree, in the midcalf and heel. Usually it is more bothersome while walking or running on uneven surfaces, gravel, or cobblestones that are sufficiently irregular and require additional stabilization of the foot.

   

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

  1. Deep posterior compartment syndrome.
  2. Tibialis posterior tendon dysfunction.

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 posterior are activated by running or walking on laterally slanted surfaces.
  2. Extremely worn footwear will cause the foot to rock during activity and aggravate the tibialis anterior.
  3. Morton foot structure.
  4. High heels and spike heels should be avoided.

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. Runners and joggers should exercise on flat surfaces.
  2. Footwear should have adequate arch support.
  3. Morton foot structure should be corrected.
