Hi Adamo,
I understand your frustrations. I am fairly flexible with my patients. I let them know where "ideal" is, why it is "ideal" and then show them how "ideal" fits into their functional activities.
...I have just come back from a course run by LJ Lee - sensational therapist btw!
So anyway, a point was made on the course about how much the bladder moves during a pelvic floor contraction and what is "normal". The point was that the range of "normal" was 2-32mm of movement. That's a large range. What really matters is whether or not the patient can *control* the movement correctly.
With respect to your assessment, I have always believed that what has been taught to us at undergrad is merely a staring point for our learning-for-life. Your functional assessment of their posture merely reflects the fact that you have evolved as a physio - into a better one. It is absolutely correct to assess in their functional positions.
Who cares if someone can control their thorax and pelvis in the anatomical position? What really matters is if they can control their joints and put them into the correct positions with the demands of sport - timing, specificity, stability, balance, symmetry, etc etc.
Go hard my brother in physio!!!!!:lol
