Involuntary Movements other Than Parkinsonism

Akinesia in Parkinsonism. Relation between spontaneous movement (other than tremor) and voluntary movements made on command.

In eleven patients with Parkinsonism there was a strong inverse relationship between the frequency of spontaneous activity of the arms and the degree of fatiguing of repetitive finger movements made upon command. The prevalence of spontaneous arm movement was related inversely (but more weakly) to the time taken to complete a pegboard test or to move clothespegs by hand; it had little associati...

Involuntary Movements following Stereotactic Operations for Parkinsonism with Special Reference to Hemi-chorea (ballismus).

When one examines stained sections of the thalamic area of the brain and sees the mass of fibres and cells in this area interconnecting almost every structure in the vicinity and receiving and sending millions of fibres to remote parts of the brain and spinal cord one marvels at the temerity of the early stereotactic surgeons who dared to place electrodes in this area and make massive destructi...

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, ...
