This patient has had low back pain since she was a child. She has coped well until the birth of her own children. The innate response to threat here is the inabillity to arch her back. Her system cannot lengthen and she cannot do a back bend or sit and perform an anterior pelvic tilt. But she can get into prone on elbows and extend no problem. Post-partum is ALWAYS post-partum and her standing strategy is reflective of this.
