Iliopsoas Muscles: Low Back, Abdomen, Groin, Pelvic, Upper Leg Pain

(Last Updated On: August 9, 2018)

Pain in the lower back, pelvic and groin area can indicate iliopsoas muscles dysfunction.

Iliopsoas Muscle Pain: Signs and Symptoms

  • Low back pain
  • Abdomen pain
  • Groin pain
  • Leg pain
  • Pelvic pain
  • Difficulty standing from a sitting position
  • Severe pain or inability to do sit-ups or crunches
  • Tendency to walk with feet turned out
  • Extreme dysfunction in the iliopsoas can cause pain under the shoulder blade that extends down to the top of the hip.

Where are the Iliopsoas muscles?

The Iliopsoas is comprised of three muscles the iliacus, psoas major, and psoas minor. The psoas major and minor attaches to the lower back vertebrae come down to the inside of the hip bone to join with the iliacus which lines the inside of the hip bone. The 3 joined muscles then run through the pelvis to connect with the upper leg.

What movements do the iliopsoas muscles control?

  • Bending over (flexes the spine)
  • Picks up the thigh (when you raise your thigh toward your stomach)

Activities that cause iliopsoas pain and symptoms:

  • Sitting for long periods of time
  • Sleeping on your side in the fetal position
  • Being overweight
  • Strenuous running
  • Climbing stairs
  • Sit ups, crunches and leg ups
  • Slumping posture

Interesting facts about the iliopsoas muscles:

  • The iliopsoas is an important postural muscle and plays a major role in human’s upright stature
  • In approximately 40% of individuals, the psoas minor is absent
  • If the iliopsoas is affected on one side,  pain runs up and down the back, hip, and upper leg. If both iliopsoas muscles are affected pain runs horizontally across the low back, pelvis, and lower abdomen.
  • The psoas major is the strongest hip flexor (bends the hip)
