Sacroiliac Joint
Question | Answer |
---|---|
muscles of the SIJ? | glut max, glut medius, glut minimus, bicep femoris, iliacus, iliopsoas, piriformis, quadatus lumborum |
Standing forward flexion test | to determine hypomobility of the ilia on the sacrum, thumbs on each PSIS, + if one PSIS moves upward w/one thumb during standing trunk flexion |
what does the standing forward flexion test indicate | restricted mobility in the side that moves up, usually indicates the side of the lesion |
sitting forward flexion test | to determine if there is abnormal biomechanics of the ilium resulting in leg length discrepancy. + when one medial malleoli apears to lengthen or shorten as the patient does a long sit-up. thumbs monitor malleolli at the foot of the plinth. |
short-to-long on the sitting forward flexion test indicates? | posterior ilium rotation |
long-to-short leg on the sitting forward flexion test indicates? | anterior illium rotation |
sitting forward SIJ test, side that changes length usually correlates w/the involved or uninvolved side of the standing forward flexion test? | involved |
SI Gap & Compression test (may perform in sidelying) | to determine if pain is of the SI origin. + when SIJ pain as you approximate or separate the ilia, while the patient is supine. |
+ SI gap & compression test indicates? | anterior SI ligament sprain if there is pain during separation (gapping) & posterior SI lesion if pain w/ilia approximation (compression) |
leg length discrepancy testing | apparent leg length discrepancy |
patient sx are back pain sometimes w/radiculopathy, uneven iliac crests/ASIS/PSIS or rotation evident upon examination of ASIS & PSIS ....could be? | SIJ |
tx for SIJ | modalities, massage/manual, normalize hypoextensible mm tissue, jt mobs, muscle energy techniques, core stabilization exercise, mobility on stability exercises. |
exercise for SIJ | resistend R hip extension, (L hip flexion), direct technique: rotate ilium posteriorly, isometric hip add after correction & stg exercises, "shot gun" technique, SI belt, |
