Hi, Lisa!
The two sets of stages of HD are totally arbitrary, very crude and lack predictive validity. Within any stage there is such a wide span of skill, disability and problems that they really lack any utility.
When someone refers to someone as in any particular stage I hear it as mumbo-jumbo. In fact, I have never described any person with HD to another healthcare professional by noting what stage they are in; and I've never had one described to me in stages.
In an attempt to subvert the use of these scales I came up with my own that Steve mentioned. I believe that there's more to learn in them than in the other sets of stages. Check 'em out!
