These findings of altered movement and glide support the concept that altered mechanics of the sacroiliac joint are correlated with the presence of pain.
Five Muscles of Sacroiliac Stabilization – Part 3 – Hamstrings
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.
Five Muscles of Sacroiliac Stabilization – Part 2 – Coccygeus and Others
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.
Five Muscles of Sacroiliac Stabilization – Part 1 – Piriformis
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.
How do we treat sacroiliac joint dysfunction with manual therapy?
The treatment for a hypomobile sacroiliac joint (SIJ) joint is Grade IV joint mobilization (also known as arthrofascial stretching).
Bones of the Lumbar Spine and Pelvis
The low back is defined by the lumbar spine, composed of 5 vertebrae, named L1-L5. The pelvis is defined by the bones of the pelvic girdle.
