There are a couple things I look for in particular when assessing the pelvis and hips.Remember that when the pelvis is in neutral, it is in a slight anterior pelvic tilt. I use pubic symphysis to ASIS to determine neutral pelvis. I will have the client slide their own hand from their belly button down until it lands on the pubic symphysis and then have them place their other hand on the ASIS - their two hands should be in the same plane. If the ASIS is in front of the pubic symphysis they are in an anterior pelvic tilt and if the pubic symphysis is in front of the ASIS they are in a posterior pelvic tilt. You will have to look at both halves of the pelvis to ensure that they are not in a pelvic tilt. Then I will look at modified Thomas test to determine the length of their hip flexors. Rarely do I find the psoas to be short - generally it is over-lengthened and the tensor fascia latae and/or rectus femoriis are the short muscles.

Thanks! I have one last question. In the video the woman you accessed demonstrated (in my eyes) an anterior pelvic tilt and a left pelvic/hip rotation. Each person has different reasons why the demonstrate this type of posture, but what are some of main factors that you look for?

Thank you for your question. Many of our clients are in a posterior pelvic tilt from excessive sitting. Most clients sit in a posterior pelvic tilt and end up with lumbar spine flexion - hence the reason for so much low back pain associated with the seated posture. Many of these individuals then exercise and are cued to 'squeeze the glutes' or 'contract their tushies' and a variety of other colorful analogies to get them to activate their posterior hip complex. Unfortunately many of these clients are already 'butt grippers' meaning they have too much activation in the posterior hip.They tend to over-clench or over-grip with the superficial gluteus maximus fibers as well as some of the deep external hip rotators which causes a de-centration of the femoral head within the acetabulum. This is what leads to the anterior femoral glide which is what we are looking for in the assessments above. For the clients that have a true anterior pelvic tilt, then some activation of the gluteals can help restore the pelvic position however even in these individuals, you have to be careful not to over-activate the posterior hip musculature because it ends up over-compressing the hip joint. Most pelvic tilt issues are related to faulty stabilization strategies (how the client is breathing and using their core muscles) of the trunk and pelvis and if this is not corrected, simply squeezing the glutes will just add to more dysfunction. Hope that helps.

Can you explain why the gluteus maximus or external rotators of the hip would be the root of the problem for an anteriorly rotated hip? Also, which muscles from this example would need to be re-activated? Thanks
