Schiff-Sher·ring·ton phe·nom·e·non

(shif sher'ing-tŏn),
when the spinal cord is transected in the midthoracic region or a little lower, the stretch and other postural reflexes of the upper extremity become exaggerated; if the transection is made in the sacral cord, a similar effect is observed in the lower limbs. The effect is regarded as a release phenomenon, that is, release from an inhibitory influence normally exerted by the spinal segments below the transection.
