How can a tight or shortened psoas muscle cause low back pain???
šŗProlonged sitting or repetitive hip flexion can leave the psoas in a shortened position, leading to adaptive tightness.
šA tight psoas pulls the lumbar spine into increased lordosis (overāarching) and sometimes a slight sideābend or rotation, increasing compressive forces on facet joints and discs.
š£This can irritate lumbar joints, discs, and surrounding soft tissues, perceived by the patient as low back pain.
