While there will almost always be other things that need to be done to fix the problem (i.e. strengthen glutes and external obliques, improve diaphragm function), when the psoas is stiff or short, it will usually need to be released with some kind of manual therapy. Whether its ART, NMT, standard massage or whatever, release will be important. Releasing the psoas is an often overlooked way to ease many cases of lower back pain and to restore proper mechanics around the pelvis and lumbar spine (IF it is a problem).
While many people now experience the many benefits of self massage techniques using tools such as foam rollers and la crosse balls, it is not common for people to perform self work on their psoas. With a foam roller it is pretty much impossible to get to this muscle. While a la crosse ball can provide some lead way, it still won't get into it specifically enough. Today, I am going to show you a neat and effective way to release your psoas yourself. Although it is pretty much impossible to duplicate the effectiveness of having a licensed soft tissue professional work on it for you (it is pretty deep and takes specific positioning and skill to get to optimally), this method is much better than nothing and can work pretty well if you do, in fact, need release on this muscle.
*Take the point on your tool and sink it in just medial (inside of it for those who aren't anatomy geeks) to your iliac crest (big hip bone that you feel above your thigh)
*Move towards your abdomen until you feel a wall or block of muscle
*Massage up and down on this muscle or sink in to a tender point and torque the tool to create some tension.
*Hold this tension and extend your hip and leg back to release the muscle.
*Repeat this up and down the length of the muscle until you feel that it is released.
If it is a problem, working this muscle can work wonders for you so give it a shot and reap the rewards.
