Thanks for the feed back sorry i didn't explain the process very well i will try again

you start with the patient in prone throughout the test; first perform unilateral knee flexion (pheasants test) stabilising the sacrum over S2/3, to determine tight hip flexors which causes a hip flexion if tight.

start on the tight side first then perform a spring test (PA) while in prone over the ischial tuberosity; this should cause posterior rotation of the hemipelvis which will indicate either the restriction of the hip flexors or restriction of the deep hip rotators attached to the ischial tuberosity; obturators and gemelli and indicates limited outflare and posterior rotation of the hemipelvis.

the next step is to apply sustained pressure over the ischial tuberosity take up the slack with knee flexion until you feel the ischial tuberosity dig into your palm. hold this position and apply hip external / internal rotation. the osteokinematics of the ischial tuberosity should derotate;meaning move away from the palm of the hand down into the surface which feels as though the bone is moving away from you and your palm should feel as though it is sinking into the body down intothe ground, with Hip ER. this demonstrates the ability and of the hemipelvis to outflare and posterior rotate. limitation will indicate limitation into this direction.

Hip ER in prone position should cause the sacrum to counter nutate (posterior rotation) because of the open kinetic chain the hemipelvis and the ipsilateral sacral base and ILA will follow the posterior rotation which is usually opposite in nature with a closed chain movement.

then sustained pressure is applied over the ipsilateral ILA adjacent to the sacral hiatus and hip ER /IR is performed . The osteokinematics of the sacral ILA should derotate with hip ER. limitation will indicate a fixation of the ILA which considered with the sacral base will lead to diagnosis of a sacral shear or torsion.

the sacral base is assessed with sustained pressure over the ipsilateral region of the sacral base while hip ER / IR is performed. the osteokinematics of the ipsilateral sacral base should increase in prominence; move towards your hand giving you the feeling of the bone pushing into your palm with hip ER and derotate with hip IR. limitation will help diagnose a flexion or an extension fixation of the ipsilateral Wikipedia reference-linkSIJ.

Finally the lumbar segments are assessed with sustained pressure over the ipsilateral facets of each level while performing hip ER /IR. the ipsilateral lumbar facets should derotate away from the thumb; the thumb should sink deep into the body toward the ground with hip ER. limitation will demostrate the fixated lumbar segments.

the fixations are released once demonstrated and reassessed.

thanks for the feedback much appreciated hope the editing has helped try it out and tell me what you think.
