There is a little discussion going on at my work re: how to say someone has a loss of 5 degrees knee extension.
Do you say -5 degrees or +5 degrees?

I'll say -5 degrees as stated in Norkin and White's, "Measurement of Joint Motion", 3rd edition, p.34

-5 degrees because the person cannot achieve 0 degrees. +5 indicates a hyperextension. The measurement is the amount of motion from neutral.

I agree with the -5. However, someone at my work is pretty adamant about the +5 and I just wanted to get some more feedback.

I agree with the -5 deg. but i usually get bas-like (anal) and make it perfectly clear by saying "5 deg. short of full". You never know who is going to read your chart and what their expectation might be and I can't stand the thought of switching back and forth for different referral sources.

And to think that I thought that our measurements were standardized! I've never thought any further about why the -5 or the +5 and accepted it as being what it is.

Just to keep things interesting. In geometry, -ve angles indicate clockwise movement, and +ve indicate counterclockwise movement.

Where I'm interning, we use -5 when measuring when pt. does not achieve full extension. However, in school we were taught to use +5, but had to be aware that state boards may use either (which could be a controversial question).

And I thought I was the only one who struggled with this one! I write it out, or at IE write PROM is 5-85 degrees. I usually picture a "line graph" in terms of ROM where beyond 0 would be in the negative, so I think it can get confusing.

Wow, we are all over the place. I write out 5 degrees flexion to 85 degrees flexion...

I'll add another version to the mix:
- 5 - 85 degrees (80 degree arc of motion with 5 degree extension deficit)
- 0 -85 degrees (85 degree arc of motion with normal extension)
- 5 - 0 - 85 degrees (5 degrees of hyper extension through 85 degrees of flexion)
It's the way some of the orthopedists used to do it when I was in school at UTMB. It just stuck with me.
