The<unk> , or<unk> 's finger flexion sign, is a clinical sign found in patients with pyramidal tract lesions of the upper limb. In this condition, stroking the dorsum of the forearm, in the area of the distal radius, with the arm supine causes abduction of the hand and flexion of the fingers. It is analogous to the<unk> –Mendel reflex in the lower limb. The reflex is named after Vladimir<unk>  and Louis<unk> -Lask.
