Thanks for the reply (interesting):
it was a test with the expected results of her foot reflexing down, but then bouncing back rapidly. My wife's left foot would kinda just stick in the down position and slowly return up to normal. All the doc said was that it could be an indicator of thyroid problems and wanted to do bloodwork.
My Dr. never really discussed any of this with me... Maybe it's because he teaches a class (The Neurological Exam) and he usually has the interns doing the exams... whatever. I don't mind helping out, but sometimes feel as though things are being overlooked..
I'm going to ask for a thyroid test - I have the swelling ankles going on (Myxedema). just curious now...
Below is some more info. -
Myxedema / “non-pitting" edema or swelling of the ankles that “bounces" right back when you push on it similar to the way a balloon would bounce back if you pushed on it.
Decreased deep tendon reflexes (such as when your doctor bangs on your knees with a reflex hammer). A “delayed return phase" of the ankle jerk reflex is a pretty sensitive indicator of low thyroid.
Babinski's reflex or extensor plantar reflex is a test for dysfunction corticospinal tract. The test consists of stroking the outside sole from heel to toe with a pointed object. The normal response is a bunching downward (flexor) movement of all the toes. In infants under 2 years of age and people with dysfunction in the corticospinal tract, this causes an upward (extensor) movement of the big toe. Babinski's reflex can occur unilaterally (in just one foot) or bilaterally (in both feet). A positive Babinski's reflex is consistent with several neurological conditions, including multiple sclerosis.
The corticospinal tract is a huge tract of nerve cells in the brain that carry movement (motor) signals down to the spinal cord. Damage to the corticospinal tract can result in muscle weakness, spasticity and excessively brisk reflexes.
