The interplay of sensory feedback, arousal, and action tremor amplitude in essential tremor. [PDF]
Sci Rep, 2023 Abstract Essential tremor (ET) amplitude is modulated by visual feedback during target driven movements. In a grip force task, tremor amplitude increased during large scale visual feedback compared to a condition with low scale visual feedback. It has not been examined whether visual feedback exclusively modulates target force tremor amplitude ...

Clinical Heterogeneity of Essential Tremor: Understanding Neural Substrates of Action Tremor Subtypes. [PDF]
Cerebellum, 2023 Essential tremor (ET) is a common movement disorder affecting millions of people. Studies of ET patients and perturbations in animal models have provided a foundation for the neural networks involved in its pathophysiology. However, ET encompasses a wide variability of phenotypic expression, and this may be the consequence of dysfunction in distinct ...

Prevalence and Relationship of Rest Tremor and Action Tremor in Parkinson's Disease. [PDF]
Tremor Other Hyperkinet Mov (N Y), 2020 AbstractBackgroundDespite the significance of tremor in Parkinson’s disease (PD) diagnosis, classification, and patient’s quality of life, there is a relative lack of data on prevalence and relationship of different tremor types in PD.MethodsThe presence of rest tremor (RT) and action tremor (AT; defined as combination of both postural and kinetic ...

Action Tremor Asymmetry Profile Does Not Aggregate in Families with Essential Tremor. [PDF]
Front Neurol, 2017 Action tremor is the hallmark feature of essential tremor (ET). While the tremor typically is mildly asymmetric, in some patients, it is markedly asymmetric. There are few data on factors that influence this asymmetry. ET is also a highly familial disease.

Parkinson's Disease Action Tremor Detection with Supervised-Leaning Models. [PDF]
IEEE Int Conf Connect Health Appl Syst Eng Technol, 2023 People with Parkinson's Disease (PD) have multiple symptoms, such as freezing of gait (FoG), hand tremors, speech difficulties, and balance issues, in different stages of the disease. Among these symptoms, hand tremors are present across all stages of the disease.

Another case of "shopping bag" tremor: a difficult to classify action tremor. [PDF]
Tremor Other Hyperkinet Mov (N Y), 2014 Zesiewicz et al.1 reported an unusual case of unilateral wrist tremor that occurred while the patient carried a weighted object (e.g., a shopping bag) or made a fist, and suggested that this could be a form of isolated isometric tremor. Here we report another patient who presented with a phenomenologically similar tremor.

Tremor in motor neuron disease may be central rather than peripheral in origin [PDF]
, 2018 BACKGROUND AND PURPOSE: Motor neuron disease (MND) refers to a spectrum of degenerative diseases affecting motor neurons. Recent clinical and post-mortem observations have revealed considerable variability in the phenotype.

Effects of STN DBS and auditory cueing on the performance of sequential movements and the occurrence of action tremor in Parkinson’s disease [PDF]
, 2014 Background:\ud Parkinson’s disease (PD) patients show a higher ability to perform repetitive movements when they are cued by external stimuli, suggesting that rhythmic synchronization with an auditory timekeeper can be achieved in the absence of intact ...
