There was no rest tremor, but three had mild postural tremor. Specific muscle activity (especially pronation of the wrist or abduction of the fingers) elicited the tremors that persisted as long(More)
We present a new method to determine contraction kernels for the construction of graph pyramids. The new method works with undirected graphs and yields a reduction factor of at least 2.0. This means that with our method the number of vertices in the subgraph induced by any set of contractible edges is reduced to half or less by a single parallel(More)
Two patients developed either blepharospasm or blepharospasm-oromandibular dystonia following chronic therapy with chlorpromazine, haloperidol, or thioridazine. In one patient, appearance of the movement disorder was associated with neuroleptic withdrawal, and in the other patient, the movement disorder began while neuroleptic therapy continued. Because of(More)

Liver and metabolic functions were normal in all patients. Asterixis always occurred as part of a toxic confusional state superimposed on a parkinsonian state associated with some dementia.

We examined postural reflexes in 50 patients in a geriatric care facility. Patients aged 60 years and older who did not have orthostatic hypotension were subjected to a standing postural perturbation, and the degree of postural instability was recorded. Sixteen patients with leg amputations, recent stroke, and leg deformities were excluded. Of the remaining(More)
