This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Adductor Magnus
A group of muscles generally denotes muscles of the same function and may share a common attachment point. Inner Thigh
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.

Adduct the thighs (bring the thigh closer to the midline of the body).   

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 upward into the lower groin and downward through the middle part of the thigh almost to the knee. Pain may be described as generalized pelvic pain which can include the pelvic bone, vagina, rectum, and sometimes the bladder.  This pain may be described as shooting up inside the pelvis and exploding like a firecracker.

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

A person with TrPs in the Magnus may experience pain that is increased by weight bearing and by sudden twists of the hip. A person may have difficulty positioning the lower limb comfortably while sleeping and prefer to lie on the opposite side. Sexual intercourse may also be painful due to TrPs in this muscle.


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

  1. Pubic Stress Symphysitis.
  2. Pubic Stress Fracture.
  3. Adductor Insertion Avulsion Syndrome.
  4. Pelvic Inflammatory Disorder (PID).
  5. Sacroiliitis.

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

  1. Sudden overload - slipping on a smooth surface while trying to resist spreading the legs to regain balance.
  2. Strenuous horseback riding.
  3. Skiing or unaccustomed long bicycle trip.
  4. Sitting in a fixed position while driving on a long auto trip.
  5. Anything where the knees are pulled together for long periods of time.

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. While sleeping on the side, place a pillow between the knees to reduce strain on the muscles of the inner thigh. 
  2. A person should avoid crossing a leg over the other knee while sitting.
  3. Sitting for long periods of time in an automobile can be minimized by making frequent stops to get out and walk around or by using the cruise control to allow free movement of the lower extremity.
  4. Use of moist heat over the adductor muscles on a regular basis followed by a gentile stretch of the muscle may help to restore range of motion and lesson symptoms.
