Focus:  Psoas, Rectus Femoris and Hamstrings in Lower Crossed Syndrome

Lower crossed syndrome is a term originally coined by Dr. Janda that describes the postural distortion of an anterior pelvic tilt.  His original concept was that some muscles in the lumbar/pelvis were facilitated (tight) and some were defacilitated (weak).  This muscular imbalance resulted in the chronic tilting of the pelvis.  However, Janda did not understand muscle strength/weakness and facilitation/defacilitation within the paradigm of trigger point therapy.  All muscles contributing to this postural distortion will be functionally "weak" due to trigger points.  Some muscles tend to adaptively shorten, and some will adaptively lengthen.

Muscles that adaptively shorten:  hip flexors (rectus femoris, iliopsoas), lumbar extensors including QL.

Muscles that adaptively lengthen:  hip extensors (glute max, hamstrings).

Usually, the source of this muscular adaptation is foot hyperpronation so that must be addressed.  Then the muscles involved can be helped with bodywork and the functional group can establish new relationships around a neutral pelvis.

In this week's course, we go over some great techniques for muscles often involved in the common postural distortion known as Lower Crossed.  The anatomy and trigger point information for these muscles has already been covered in previous weeks' lessons.  This week we focus on some great techniques in side position and prone to treat psoas, rectus femoris and hamstrings.
