It came out good tot excellent. The only thing is that one has to clearly explain that 10 = completely impossible. So, the bigger the problem, the bigger the number should be.

Giving it a numeric value seems to be a good idea. I'm curious as to the reliability of the scoring process. In other words a 1 or a 4 score may not be the same to every person. Even with the same person as their own control it may not work. The problem is the age old problem of giving a numeric score to a subjective or atleast poorly defined scale e.g. 1-10; 1 being not bothersome at all and 10 completely limiting. I would like to hear your comments on this. Thank you! Patrick Zerr www.apluspt.com The easiest way to prepare for the National PT Exam! www.summitpt.com Summit Physical Therapy; Tempe, Arizona
