OBJECTIVE To evaluate the clinical characteristics, associated features, and treatment response of a large orthostatic tremor series seen over a 26-year period. METHODS We reviewed the medical records of 45 patients seen between 1987 and 2013 who fulfilled the diagnostic criteria for orthostatic tremor. RESULTS The mean age at onset was 59.5 years and 23/45 (51%) were men. A family history ...

This paper reports the study and results of modeling and online compensating of movement disorder stemming from multiple sclerosis (MS) via artificial neural networks. We trained and tested a cascade-correlation neural network with Kalman filtering on data collected from 11 subjects with MS. The test subjects use headcontrolled mouse emulators to move a cursor to a series of random targets on s...

BACKGROUND Unilateral hand tremor is one of the cardinal symptoms of Parkinson's disease. Additionally, mechanical traumatic hand movement is one of the risk factors for carpal tunnel syndrome. Our objective in this study was to examine whether repetitive mechanical movement may be related to the development of carpal tunnel syndrome in Parkinson's disease with unilateral hand tremor using neur...

There are few data on rate of progression in essential tremor (ET). To quantify the rate of tremor progression in a cross-sectional sample of 348 ET cases in an epidemiological study; characterize the relationship between age of tremor onset and rate of tremor progression in that sample; and characterize the relationship between age of tremor onset, rate of tremor progression, and severity of u...

First published February 16, 2005; doi:10.1152/jn.01218.2004. The purpose of this investigation was to determine the effects of healthy aging on the regularity of physiological tremor under rest and postural conditions. Additionally, we ...

One of the important areas modern neurology is movement disorders, due to their negative impact on daily activity and quality life patients. Dystonia third most common extrapyramidal disease. Often, dystonia accompanied by trembling hyperkinesis, however, known data dystonic tremor are scattered not systematized, its fixation causes difficulties lack clear tremorographic characteristics. Many i...

INTRODUCTION Patients with cervical dystonia (CD) often have limb tremor that is clinically indistinguishable from essential tremor (ET). Whether a common central mechanism underlies the tremor in these conditions is unknown. We addressed this issue by quantifying limb tremor in 19 patients with CD and 35 patients with ET. METHOD Postural, resting and kinetic tremors were quantified (amplitud...

The most frequently seen types of tremor are essential (ET) and parkinsonian tremor (PT) and in some patients clinical characteristics of these tremor types overlap. It is vital to distinguish between these two types of tremor in order to reach the right diagnosis and select the appropriate treatment. One of the widely used methods for tremor detection and discrimination, appropriate for a quic...

We propose hand tremor as a new type of input that can corroborate psychosocial conditions. An Android application was able to distinguish tremor variability differences between people with and without diagnosed hand tremor. Tremor measurements also corroborated self-assessment of sleep quality. Hand tremor evaluation may be a monitorable, implicit input to systems that respond to various psych...
