Extract

In 1920 Marinesco and Radovici (1) described a reflex contraction of the homolateral chin muscles in response to stimulation—pricking or pinching—of the thenar surface of the hand. They record a case of amyotrophic lateral sclerosis where such a stimulus evoked a slow contraction involving the triangularis and quadratus menti of the same side. In this particular case the reflex could be elicited not only from the palmar region, but also from the skin of the arms, thorax and abdomen, also by stimulation of the perinæum, effected by passing a urethral sound. The lowest threshold of reflex excitability was, however, obtained on the palm.
