Involuntary Movements. ? Torsion Spasm

Hemifacial spasm and involuntary facial movements.

Hemifacial spasm (HFS) is characterized by tonic and clonic contractions of the muscles innervated by the ipsilateral facial nerve. It is important to distinguish this from other causes of facial spasms, such as psychogenic facial spasm, facial tic, facial myokymia, blepharospasm, and tardive dyskinesia. Magnetic resonance imaging and angiography studies frequently demonstrate vascular compress...

A case of involuntary spasm movements in amputation stump

Painful jumping stump is characterized by persistent choreiform or myoclonic involuntary movements and severe neuropathic pain in the stump of a limb following amputation. This syndrome is also defined as„ trepidation du moignon‟, convulsive movements of the stump” or“jumpy stump”.The pathophysiology and etiology have not yet been clearly defined. We describe a seventy four year old man, who ha...

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.

Nonketotic hyperglycemia with involuntary movements

Cortical activities associated with voluntary movements and involuntary movements.

Recent advance in non-invasive techniques including electrophysiology and functional neuroimaging has enabled investigation of control mechanism of voluntary movements and pathophysiology of involuntary movements in human. Epicortical recording with subdural electrodes in epilepsy patients complemented the findings obtained by the non-invasive techniques. Before self-initiated simple movement, ...
