The Pelvic Crossed Syndromes: A reflection of imbalanced function in the myofascial envelope; a further exploration of Janda’s work

Structurally, the sacrum-coccyx provides the dual roles of serving as the base of the spinal column while also forming part of the pelvic ring. Physiological movement control of the pelvis and the spine are functionally interdependent. In particular, intra-pelvic control, (that between the ilia and sacrum/coccyx in support and control of the forces and small movements within the pelvic ring) is fundamental to controlling its spatial organization as a whole and its control on the femoral heads, all of which directly influence spinal alignment and control mechanisms. This involves coordinated activity in the related neuro-myofascial systems in providing mechanisms of both intrinsic and extrinsic support and control.
