These findings of altered movement and glide support the concept that altered mechanics of the sacroiliac joint are correlated with the presence of pain.
The connection between the hamstrings and the sacroiliac joint is through what is known as the superficial back line myofascial meridian/anatomy train. If the hamstrings are tight, their tension pulling force will be exerted through the sacrotuberous ligament and onto the sacrum.
The coccygeus and levator ani are technically muscles of the pelvic floor, however, they are also muscles whose contraction forces cross the sacroiliac joint and therefore often tighten when a sacroiliac joint condition exists. The coccygeus attaches from the sacrum and coccyx to the ischial spine of the pelvic bone.
Even when the original reason for the sacroiliac stabilization is valid, often the human body overdoes it and tightens the musculature excessively and/or keeps it tight long after it needs to be, so the musculature becomes stuck in a chronic pattern of hypertonicity.
Moist heat and stretching is recommended for a hypomobile sacroiliac joint (SIJ) and/or tight musculature that accompanies a hypomobile or hypermobile SIJ.
The treatment for a hypomobile sacroiliac joint (SIJ) joint is Grade IV joint mobilization (also known as arthrofascial stretching).
Assessment of sacroiliac joint dysfunction is done by motion palpation, in which the joint is challenged to move while the motion of the joint is assessed.
Because of the tendency of one sacroiliac joint (SIJ) to compensate for the other when motion is dysfunctional, typically both SIJs become dysfunctional.
The sacroiliac joint is unique in that it is a transitional joint between the sacrum of the spine and the ilium of the pelvic bone of the lower extremity.
The sacroiliac joint (SIJ) medley of tests is a series of five assessment tests to determine if the SIJ is the causative agent of the client’s pain.
