That situation occurs frequently due to patients current health status and/or age. This is the standard test position, however you can test a patient in other positions as long as you have documented the test position properly. It is no longer considered the standard test though. Thanks for you question and for watching our videos.
When measuring active range of motion, we typically have the patient move against gravity. If extension was measured in supine, gravity would be assisting the movement and that wouldn't be an accurate measure of the patients ability to move actively. Thank you for watching and we hope that answers your question.
The stationary arm is the one that remains lined up with the midline of the trunk. Because the goniometer cannot be placed against the trunk (the arm is in the way) it may shift a little while following the humerus with the moving arm but as long as the stationary arm is aligned with the trunk at the time you read your measurement than a little movement is ok when it is getting positioned. We hope that answers your question and thank you for watching.
What if the pt cant prone?

It looks like in this video the stationary arm is moving instead of the moving arm of the goniameter
