I wish to apologise unreservedly. I have posted irresponsibly and caused potiential agro for those on this thread.
Don't get me started the accuracy of correction by degree-increments
Memo to self. Must get David started on correct by degree increments. 
Actually i think that it is and excellant idea to measure correction by increments although i would not claim to be more accurate than, say, to the nearest 0.5 degree or possibly even to the nearest whole degree (of course i'd need to round to the nearest degree for that.. I think NOT to measure in this way is frankly irresponsible. Honestly who would'nt?
Nice weekend David .

This post was intended purely, absolutly entirely unequivokally and utterly as a wind up (primarily for Davids benefit.) I DO NOT claim to be able to measure Joint positions to within 0.5 degrees. Really i don't.
Sorry in particular to Ian. Derek, i suspect, had a shrewd idea what i was doing knowing, as he does, that i am an evil sod with an infantile sense of humour.
Somebody smite me! I have infracted! I deserve smiting!
Dragging it back to the point, which was halfway relevant before i had an attack of lets get a rise out of david syndrome.
I think there is a place for measureing improvement by increments. I do not beleive the readings are repeatable from an intertester viewpoint with anything but the grossest degree of accuracy. I beleive that the intra tester repeatability of some measurements is sufficient to give it clinical relevance. However i feel the real value of monitoring increments is for reasons of patient compliance. It can be monumentally difficult to acheive compliance with stretches, particularly in teenagers. If they beleive that i can measure the improvement it sometimes focuses their motivation somewhat. For this i am willing to suspend disbeleif. Call it placebo diagnositics if you will.
BTW my BSc research was on intra and inter tester repeatibility of RSCP using a blacked out goniometer to blind the testers (so they aligned the instrument without seeing the graduations then passed it to me to read the degrees off the other side), and concealed patients from the leg up so that the tester did not know they were testing the same patient.
The results varied between bad and downright terrifying.
Apologetic regards
Robert
