Hi again.

Jerry, your site was working this time!

I agree that passivce accessory motion testing is very important in the assessment and treatment of the Wikipedia reference-linkSIJ, PS, etc.

Also, Dr Barbara Hungerford's PhD work was on the motion of the SIj during the sotrk test in both the hip flexion and stance phases in people with pelvic girdle pain and in those without. Her work confirmed the nutation/locking in of the SIJ in normals and counternutation dysfunction in those with pelvic girdle pain.

I would be interested to know what your 16 patterns are. Is your system of testing different to that Diane Lee describes in her book "The Pelvic Girdle"? The tests i use are the Standing and sitting FFT, Stork - hip F and stance phases, "squish" test, AP arm test (use force through ASIS), CC arm test (use force along the leg) and another test which is in prone AP via the ASIS while palpating the SIJ (is there a name for this test??).

Are yours similar?
