A search on www.google.com showed different meanings

One in English said
    Mendel-Bechterew sign:  Dilation of the pupils when they are
    exposed to light;  also known as “paradoxical pupils”.

But a number in European languages indicated it referred to the flexion of
    the small toes after percussion of the lateral edge of the foot

Any neurologists out there?
