opisthotonos

(o?pis-thot'o-nos) [? + tonos, tension]
A tetanic spasm in which head and heels are bent backward and the body is bowed forward. This type of spasm is seen in strychnine poisoning, tetanus, epilepsy, the convulsions of rabies, and in severe cases of meningitis. In the latter case, the patient's neck is rigid and the head retracted, seeming to press into the pillow.
