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.

Deep Pressure Massage to the Low Back – Apply Pressure Perpendicularly

Maximal pressure for the effort used is achieved if the angle of your force into the client is perpendicular to the contour of the region being worked. To apply this concept of working perpendicularly, the client’s back and pelvis can be divided into separate regions based on the curve of each region.
