Unfortunately there are no articles as this is a new direction of assessment.
The OGI is doing a trial of the idea that pelvic angles are the most objective information on the patient's condtion. The person pursuing it will be pubishing a research paper.
However, I have tried to find similar information and there appears to be none.
I have used the test for over 15 years and with over 1,000 patients.
the difference of pelvic angles works its way up to the lumbar and higher.
The most common muscles inscoliosis are the serraus posterior inferior on the right and the QL on the left which are attempting to anchor a problematic right psoas which in turn is being activated by a left adductor longus.
try the tests as indicated and see what your results are as this is a new direction and there is little in the way of corroberating evidence.
An international magazine in the UK is interested in the paper and so is the conference in Holland in 2009. Be ahead of everyone by trying the test.
Hope that tish is helpful.
