In summary, I feel that in order to get reliability we should develop the physician as well as the tools. This will show us a consistency in findings in that it will be there regardless of what posture a person assumes. It may be wise to examine in the posture that most aggravates the condition. The same tissue needs to be examined at the same time and using the same screening method . It is also wise to use a variety of screens so the consistent primary can be uncovered.
Functional screens are more reliable because they show how a tissue is functioning.
Positional screens just show asymmetry of position. Physicians need to learn how to stay clear, open-minded and centred so that they can truly observe the tissues as they are. To see through the clearest point in their windscreen and thus, be a catalyst for healing energies and become a healed healer. I would suggest that if some of these factors were included in the examination process , then maybe interexaminar reliability may improve. If there is no reliability then we have not identified the real cause, or may only have found the compensatory layers.
