Patient SS is a 62 year old female retired teacher who was evaluated in my office in mid-2005 for complaints of right-sided low back and posterior thigh pain. My initial evaluation revealed a condition of right sacroiliac joint instability which was resolved within 4 physical therapy (PT) sessions. The patient returned to my practice 6 months later with another episode of right sided low back and thigh pain aggravated by having to sleep on the floor for 2 weeks. This again was resolved within 4 PT sessions. The patient again returned after 3 months with a worsening of her symptoms with pain radiating further down her leg to her toes. This time treatment lasted for about 4 months with a significant decrease in pain intensity but no resolution as previous treatments. It was obvious that another treatment approach was necessary. In my training as a CHEK Practitioner, we are taught to take an integrated and holistic approach to chronic musculoskeletal pain. Upon reassessment, it was discovered that her right sacroiliac joint and posterior-lateral thigh pain was created by increased right lower extremity weight bearing caused by a right rotated atlas (C1, or 1st cervical vertebrate) influenced by her right eye dominance (she has a left eye strabismus, or “lazy eye”) and a recent switch towards chewing on the right side of her jaw (due to 3 teeth on the upper left mouth being removed). It was discovered that stress played a major role in her symptoms. When exhausted or fatigued her right eye vision worsens which drives her atlas excessively to the right, aggravating the right lower extremity pain. Before this reassessment her MD wanted to give her epidural injections for the pain and to “seriously” consider spinal surgery.
