of a neurologist who doesn't check Babinski reflexes?

I've been seeing an MS specialist (I'm undiagnosed) since Oct. 2006. In all of that time, she's only checked my Babinski reflexes one time. Her NP has never checked my Babinski reflexes. This reflex hasn't been checked in over a year, though my other reflexes have (and those have been abnormal too.)

Since I am undiagnosed, wouldn't it stand to reason that this would be important to the diagnostic procedure? When all of my weird symptoms started in May of 2006, the first neurologist (and the one I saw between that one and the MS specialist) checked my Babinski reflex and it was present in my right foot. A rheumatologist I saw over a year ago checked it too and again, it was present.

During my first appointment with the MS specialist, she did check, and it was present again in my left foot. However, she "lost" the dictation from my exam and had to recreate it, and in the record it states that I pulled my foot away when she tried to check my Babinski reflex (I did not.)

I'm guess I'm confused about this. Is the presence or absence of this reflex just not that important in diagnosing neurological problems?
