Its good to be proactive but don't stress over it.
The reason I asked if it was a self diagnosis is there are common misalignments that are a result of a structural abnormality (abnormal from the referred anatomical ?correct? position). As a result it common practise to assess three determinates of lordosis, a decision should then be based on findings of two of the three.
1, Lordotic curve (>30 degrees is believed to be excessive)
2, Position of PSIS and ASIS (a marked deviation of about 5 degrees is meant to represent anterior pelvic, 15 degrees represent clinical importance)
3, Increase or decrease in hip join angle.
As for advice, the best things you can do are:
-correctly perform impaired movement?s e.g. correcting any lumber extension during shoulder flexion. (Note: obviously you need to know how the body should move in order to do this.)
- perform exercises that require control of the impaired muscles. A really good exercise is the bird dog
- try not to stay seated for prolonged periods. Spending 30 minutes in a position of misalignment is enough to start physiological adoptions to the length of the muscle, if however, you get up and move you can regain about 50% of that original stiffness in 3 minutes, to get 100% back you need to be back in that correct alignment for an equal or greater time.
Hope this helps a little.
