Hi Arifa,

Both authors which Linbin has suggested will be very helpful in assessment and treatment of pelvic girdle and sacroiliac dysfunctions.

Until you get those books... An upslip presents itself just as it sounds, the entire pelvis (right or left) is sheared up on one side. Therefore on palpation every bony landmark will be superior on one side, i.e. ASIS, iliac crests, PSIS, ITs, and pubis. As far as tests go, there are lots of them and depending on who you read the reliability will vary. Both the stork test and PSIS levels on lumbar flexion are pretty common ones and generally relied upon, however a positive test alone does not indicate an upslip, which is why palpation is so important. A positive test will only indicate the side of dysfunction, correct assessment then needs to be made by palpation in order to find the type of dysfunction, i.e. upslip, anterior rotated pelvis, inflare, outflare etc. I would also recommend the squish test, which is as simple as compressing the Wikipedia reference-linkSIJs anteriorly through the ASISs on a supine patient. Here, hypomobility indicates the side of dysfunction.

Good luck and again, I would suggest picking up the above books.
