In spastic su-bjects, motoneuron firing threshold may decrease to a level in which the spindle afferent output eli-cited during muscle lengthening is now sufficient to reach threshold for motoneuron firing (16). This shift in threshold can be thought of as an The ankle clonus test, a method for evaluating the integrity of the spinal cord during operations for scoliosis, is predicated on the finding that patients recovering from general anesthesia normally have temporary ankle clonus bilaterally.
