Abstract

ADDUCTOR REFLEX OF THE THIGH  This is a reflex of the adductor muscles of the leg. It is a sensitive and important reflex but has been somewhat neglected in favor of its great neighbor, the quadriceps reflex. The adductor muscles extend from the pelvis to the leg, and anything that brings about a concussion of either of these bony structures, so that the distance between the points of origin and the points of insertion of the abductors is increased, produces the adductor reflex.To elicit the homolateral adductor reflex, it is best for the examiner to place his finger on the medial condyle of the femur, the leg being slightly abducted, and tap the finger, thus causing a further abduction of the leg. Any point along the inner side of the leg, including the region of the malleolus internus, or even the achilles tendon, may be tapped. The more exaggerated
