Gluteus Maximus Trigger Points and the Sacroiliac Joint

Functionally, the gluteus maximus is an important muscle primarily because of its pelvic posterior tilt concentric contraction function, and because of its isometric stabilization function to armor/protect the sacroiliac joint. Manual therapists should be mindful to especially assess the superior fibers lateral to the PSIS.

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.
