Both deep and superficial reflexes exaggerated; ankle clonus both sides; hyperæsthesia of abdomen and face.

There was neither ankle nor patellar clonus, and the other reflexes were present and normal.

The plantar and patellar reflexes were much exaggerated, and there was ankle clonus, most marked in the left limb.

Cord compression, with either associated T2 cord signal abnormality or clinical findings of clonus, was most predictive of subsequent surgical decompression.

There is an attempt at, but no true, clonus; that is, passive flexion of the foot causes two or three jerky movements.
