The phenomenological classification of tremor is determined by finding out: c which parts of the patient’s body are affected by tremor? c what types (or components) of tremor, classified by state of activity, are present at those anatomical sites? The following definitions are used to describe the various tremor components evident on examination: c Rest tremor is a tremor present in a body part...
purpose: transcranial magnetic resonance guided focused ultrasound (mrgfus) is a new development in the field of functional neurosurgery. a comprehensive review of the current literature was performed to evaluate of transcranial mrgfus in treatment of essential tremor (et) and parkinson’s disease. methods: articles available in electronic databases of pubmed, and web of science, as of july 2016...
BACKGROUND Dystonia and tremor share many commonalities. Isolated tremor is part of the phenomenological spectrum of isolated dystonia and of essential tremor. The occurrence of subtle features of dystonia may allow one to differentiate dystonic tremor from essential tremor. Diagnostic uncertainty is enhanced when no features of dystonia are found in patients with a tremor syndrome, raising the...
Forehead tremor has only been reported in two patients with essential tremor, one with rhythmic tremor and the other with dystonic tremor. We report 4 new patients with essential tremor who present a 4-6 Hz frontal tremor registered by electromyography and unusual features like frontal tremor preceding limb tremor or unilateral involvement. Frontal tremor is present in some patients with essent...
We assessed the duration and severity of tremor in a real-life ambulatory setting in patients with psychogenic and organic tremor by actigraphy, and compared this with self-reports of tremor over the same period. Ten participants with psychogenic tremor and eight with organic tremor, diagnosed using standardized clinical criteria, were studied. In an explicit design, participants were asked to ...
High frequency deep brain stimulation of the thalamus can help ameliorate severe essential tremor. Here we explore how the efficacy, efficiency and selectivity of thalamic deep brain stimulation might be improved in this condition. We started from the hypothesis that the effects of electrical stimulation on essential tremor may be phase dependent, and that, in particular, there are tremor phase...
BACKGROUND Some recent experimental data suggest a possible role of LINGO-1 in the pathogenesis of multiple sclerosis (MS). In an attempt to identify genetic biomarkers related to MS susceptibility, we genotyped two common SNPs in the LINGO1 gene which have been associated to other neurological conditions, in patients with MS and in healthy subjects. These SNPs are linked to several SNPs within...
[1] Acoustic emissions and tremor‐like signals are widely recorded in laboratory experiments. We are able to isolate the physical origins of these signals using high resolution nanoseismic analysis. The use of a picometer‐sensitive, wide‐band sensor array permits us to determine force‐time functions and focal mechanisms for discrete events found amid the “noise” of friction, similar to how low ...
Objective: The aim of this study was to differentiate tremors on the basis of the electromyographic examination. Methods: A total of 100 patients, having different kind of tremors were prospectively analyzed. A detailed neurological and electromyographic examination was performed. The tremor was studied in all limbs positions. Clinically, patients were divided into seven diagnostic groups fulfi...
