B3. Stereotaxic Surgery for Abnormal Involuntary Movements

The surgical treatment of abnormal involuntary movements.

In the past twenty-five years it has been my pleasure to work with many young Japanese surgeons who have visited our clinics and laboratories in Chicago. Naturally I have been delighted to note the progress which each one of these has made after his return home to Japan. Now I find them occupying posts of great importance and responsibility in your hospitals and medical schools. Among these men...

EMG patterns in abnormal involuntary movements induced by neuroleptics.

Electromyographic (EMG) activity of abnormal involuntary movements and their modifications after Piribedil, a dopaminergic agonist, were analysed in patients presenting with tremor or tardive dyskinesia induced by treatment with neuroleptics. Quantitative analysis of EMG bursts and of their phase relationships with bursts of antagonist muscles revealed differences between tremor and tardive dys...

Deep Brain Stimulation for Involuntary Movements

stimulation (DBS) has been developed during the last two decades by several investigators. In 1987, Benabid and his colleagues suggested the usefulness of high-frequency stimulation of the ventral intermediate nucleus of the thalamus for treating drug-resistant tremors and avoiding the adverse effects of thalamotomy. Since then, DBS has been used as an alternative to functional neurosurgery for...

Involuntary movements of pelvic stump

Although involuntary movements of stumps are less frequent than phantom sensation or other neurological sequelae of limb amputation, they represent a phenomenon that has been known for many years. The pathophysiology remains unknown, but it seems to be related to damage to the peripheral nervous system. Treatment is not standardized, but antimyoclonic drugs seem to be useful.
