This is the technical name of the muscle being described.  This name may be used to find additional information in any medical resource. Pectineus
A group of muscles generally denotes muscles of the same function and may share a common attachment point. Hip 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 pectineus will flex the hip and adduct the thigh.

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 pectineus will refer pain directly over the muscle, which is located in the anterior pelvis.  Pain may also be felt deep into the groin as well as in the hip joint.

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

A person with pectineus TrPs will most likely be experiencing pain or dysfunction from adductor and/or iliopsoas TrPs as well.  They may also notice restriction in abduction of the hip such as when sitting in thelotus position.


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

  1. Obturator nerve entrapment.
  2. Hip joint disease.
  3. Pubic stress symphysitis (more common in distance runners and those who compete in contact sports).
  4. Upslip of the innominate bone.

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

  1. Tripping and falling may activate TrPs in the Pectineus.
  2. Horseback riding in which the rider uses the thighs, rather the legs and feet to grasp the hoarse.
  3. Lower limb length inequality.
  4. Sitting cross-legged with the hips in a jackknifed position

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 any limb length inequalities.
  2. Do not sit in a jackknifed position.  To achieve this, be sure that the knees are not above the hips while seated.
  3. When sleeping, a person with pectineus TrPs should lie on the unaffected side and place a pillow between the knees to prevent aggravation of the muscle.
