Question
I am convinced of it that the psoas major psoas minor and illacus are responsible

in many people back pain as the source of pain.

while not being the cause by mainting the correct length and muscle

quality of these muscles it would go along way in lower someones said back

pain.

and the rest of the puzzle would be to greatly increase muscle

endurance of many surrounding muscles and to get the correct

order (and or get inhibited) of the muscles firing

i have very much tried on myself to get at 2 of the TrPs

being the one under the abs and the other close to the asis

my question is this

could you please tell me exactly all of the trigger points areas for

all 3 of the muscles just what happens to which muscle when the trigger

point is realised. ie does the asis TrP just realease the

illacus. and ie does the TrP under the abs just realease

the upper half of the psoas.

and if you have exacting strageties if all of the trigger points should

be released and worked on or not.

i am played around with on myself and are almost thinking that the

TrP near the asis is the most critical one while i may even be best to

not touch the TrP that is under the abs.

thanking you in advance

Answer
great question jii. i think you are so correct. i see so many people with tight Psoas muscles, usually the ilio-psoas. It is a very difficult muscle to stretch. i have 2 excellent ways to stretch it. 1 of them you need someone else to help you.
while laying on your back the other person will use his knuckles or fingertips half way between the belly button and ASIS (or just above the and medial to the ASIS) have that person apply good amount of pressure in a clockwise or counterclockwise motion  (it will be quite painful) do that 2 x a day for a few weeks and it will loosen up.
the 2nd way i came up with on my own after some desperation on my part. (i will try to explain this coherently) take a tennis ball and lay on top of the ball with the ball in between your ribs and ASIS (same area mentioned above) if you have the ball under your left ASIS make sure that leg is straight and slightly extended back (only bend the leg at the hip joint or buttock region) use your right leg which can be bent at the knee to push off the floor to roll your body over the tennis ball (be careful not to go over the ribs (they could fracture) it takes a few minutes to get "the spot" but play around with it and you will find the psoas trigger point.
i hope this helps. if not email me back and we could do a Instant message chat and i could show you on a webcam.
