AN APPARENTLY NORMAL MAN WITH PERSISTENT ANKLE CLONUS

Ankle clonus

Clonus is a series of involuntary, rhythmic, muscular contractions, and relaxations. It may be caused by interruption of the upper motor neuron fibers such as stroke, multiple sclerosis, or by metabolic alterations such as severe hepatic failure or serotonin syndrome. We present a video case of impressive left ankle clonus in a patient with old right middle cerebral artery stroke.

Exoskeleton Simulator of Impaired Ankle: Simulation of Spasticity and Clonus

We developed a prototype of an exoskeletal patient simulator that allows clinical trainees to experience and learn about ankle disorders related to hemiplegia. The exoskeleton exerts abnormal joint torques by tendon mechanisms while realizing complex ankle movements and realistic bone and skin features. Using this exoskeleton, we simulated the resistances of spasticity and clonus, which are typ...

Sudden cardiac death with apparently normal heart.

BACKGROUND Mechanisms of sudden cardiac death (SCD) in subjects with apparently normal hearts are poorly understood. In survivors, clinical investigations may not establish normal cardiac structure with certainty. Large autopsy series may provide a unique opportunity to confirm structural normalcy of the heart before reviewing a patient's clinical history. METHODS AND RESULTS We identified an...

EFFECT OF IODINE DEFICIENCY ON I.Q.LEVELS OF APPARENTLY NORMAL INHABITANTS OF AN ENDEMIC GOITER AREA

a young man with an ulcerated lesion on the right ankle

we present a case of epitheloid sarcoma that was referred with a 2×3cm ulcerated lesion on the right ankle and edema of the lower leg. foot drop of the right side was present that had caused walking difficulty. after a few months, he developed several sporthricoidal nodular lesions on the medial aspect of right thigh, inguinal lymphadenopathy, weight loss, anorexia and respiratory symptoms. che...
