A 33-yr-old pregnant woman developed recurrent motor-ataxia-like abnormal motion of the lower legs during the recovery from spinal anesthesia with hyperbaric tetracaine for repeated cesarean section. This symptom was thought to be due to the disturbance of coordination associated with the loss of positional sensation because deep sensory blockade seemed to be stronger and longer than motor blockade. The etiology of this abnormal motion could not be explained clearly, but her anatomical structure of the spine and her sensitivity to local anesthetic may have been related to this phenomenon.
