Can be either.

If the deviation is only a small amount the Cobbs angle may not show it.

However, the scoliotic patterning is due to pelvic angle differnces in many patients. The adductor longus activates a response in the contrlateral psoas. The psoas will put a torsion rto the spinal column ant the QL on the contralteral side to the psoas and the serratus pos inf on the ipsilateral side will try to counter the rotoWikipedia reference-linkscoliosis that the psoas would create.

The proprioceptive sense will try to maintain face forward or torso and lower extremity alignement.

The most common lateral deviation of the lumbar to the left is thus accomplished.

Presently I have a patient who had a major scoliosis that was to be treated by Harrington Rod Implant, but the opeation will not be needed and the scoliosis is correcting to a more neutral pattern. Radiographic assessmentt is set for November.

Little research has been done on the pelvic angles factor. This is being done by the OGI after I presented my information to them.

Look for the research paper in about 6 months or earlier.
