Hi,
Thanks for your post.
I will take a look at the book you suggested even though I believe the breathing problem is a symptom of mySijoint condition. I don't hold too much importance for my score of 22 and that test as it is very general. Symptoms described on there can apply to many different conditions, I do not think they are very specific. As you said: its indicative for hyperventilation syndrome, to me a syndrome is not a cause but a side effect of something else.
I understand the relation of the diaphragm with muscle balance. It is easy to understand that any muscle working improperly will create all kinds of imbalances in the rest of the body. The hardest part is finding why it creates that and where it is coming from. Most people stop at one symptom and treat that specific area instead of making correlation of it all and understand the full pattern in order to correct the root of it. An Si joint injury creates all kinds of tightness and pain around the body and mimics many other different condition.
Have a good day.
