Lower Crossed Syndrome

The Anterior Pelvic Tilt, also known as, “Janda’s lower crossed syndrome” is a dysfunction that is created by the action of muscles in opposite directions. The tight hip flexor combines with the tightness in the erector spine and the back extensor, which leads to the anterior tilt. These three muscles act like a force, which produce the anterior rotation. However, this muscular dysfunction leads to protruding belly and butt sticking out and creates a large curve in the lower back.  The Anterior Pelvic Tilt causes some muscles to be tight and other muscles to the lengthened. Specifically the muscles in the front of the pelvis become short because of their position, whereas the muscles at the back (hamstring) become lengthened because of the pelvis moving forward.  The symptoms and signs are as follows: 

  • Lower back pain – Lower back pain is a problem that almost everybody will face at some point. One of the common causes of lower back pain is due to Anterior Pelvic Tilt (APT). This occurs when pelvis, i.e., three different bones move forward. 
  • Assumed pain and restriction of hamstrings. 
  • Medial rotation of the femur at the hip. 
  • Difficulty in standing after a long period of sitting. 
  • Lower back pain while lying flat on your back
  • Trigger joints
  • Irritated facet joints – The facet joints at the spinal cord are stained because of poor posture and poor flexibility of the muscles. Another reason for pain in the lower back. 
  • SI joint dysfunction – Sacroiliac (SI) joint dysfunction is caused due to pain in the lower back. This joint connects the sacrum, i.e., the triangular bone at the bottom of the spine with the pelvic area.
