Twisting of the dural

Common symptoms associated with a Category I pelvic rotation:

  1. Visceral disturbances 
  2. Skin Disorders Numbness in the Facial Structures 
  3. Numbness in the extremities 
  4. Low Back Pain 
  5. Anxiety 
  6. Headaches 
  7. Weight Problems 

Category II Subluxation:  Sacral iliac ligaments stretch allowing the sacral iliac joint to separate.  This hypermobility of the sacral iliac articulation results in postural distortions: the sacrum slips (tilts) to one side resulting in a functional leg length discrepancy; the spine unbalances and the head tilts to one side.

Classical postural distortion patterns associated with a Category II subluxation:

Category II, Pattern I:  Head tilts left, shoulder drops to the right, the pelvis (sacrum and both innominates) tilts left 

Pattern II (functionally short left leg): This pattern can reach the level of the foot resulting in foot twist (supinated left foot - pronated right foot)

Common symptoms associated with a Category II Subluxation:

  1. TMJ symptoms - TMJ reciprocates with the SI Joint.  The TMJ will change its position to compensate for a Category II Subluxation.  This can result in changes in the occlusion (bite), balance, hearing and neck position. [Neck and/or ear pain, Tinnitus, Headaches (lateral)] 
  2. Shoulder/arm/hand pain 
  3. Chest pain (lateral) 
  4. Low Back Pain Thigh pain (lateral) 
  5. Knee/ankle/feet problems 

Muscles that typically are in spasm:

  1. Temporalis 
  2. SternoCleido Mastoides 
  3. Latissimus Dorsi 
  4. Sartorius 
  5. Gracilis 

Category III Subluxation: the sacral iliac ligaments are torn, allowing a greater separation within the weight-bearing SI Joint.  This results in degenerative changes within the spinal intervertebral discs.  

Common symptoms associated with a Category III Subluxation:

  1. Numbness/ pain and/or burning down back of the leg 
  2. Chronic leg tightness 
  3. Bowel and/or bladder dysfunction 
  4. Pain on sitting/rising Pain on coughing 
  5. Coldness in the feet and hands 

Typical body lean patterns seen with a Category I-III Subluxations:

  1. Forward (sagittal plane) leans 
  2. Lateral (frontal plane) leans  (See Photo Below)

Category II, Pattern II:  Head tilts right, shoulder drops to the left, the pelvis (sacrum and both innominates) tilts right 

Pattern I (functionally short right leg): This pattern can reach the level of the foot resulting in foot twist (supinated right foot - pronated left foot) 

Three Categories of Sacral Occipital Lesions (courtesy of:  Howat J. Chiropractic: The Anatomy and Physiology of Sacro Occipital Technique).  

If there is a structural block preventing the normal extension/flexion between the occiput and sacrum, the following subluxations (postural distortions) can result:

Category I Subluxation (typically seen in pediatric patients): a misalignment of the innominates on the sacrum in which one innominate is more anteriorly rotated relative to the ipsilateral innominate (referred to as the sacral boot mechanism):

  • A distortion (twist) occurs in the dural membrane surrounding the brain and spinal cord (see animation below)
  • This twist in the dural membrane results in sagittal plane rotation of the innominates
  • The sagittal plane rotation of the innominates unlevels the pelvis. This unleveling of the pelvis results in a global postural shift referred to as BioImplosion

This patient has a mixed postural distortion pattern:  PreClinical Clubfoot Deformity and a Category II, Pattern II Cranial Sacral Subluxation. The interactions between the two postural distortion patterns result in a skewed postural shift (e.g., in a pure Cat II, P II Subluxation, the pelvis would be tilted to the right).
