The Kurtzke Expanded Disability Status Scale (EDSS) is a method of quantifying disability in multiple sclerosis. [1] [2] The scale has been developed by John F. Kurtzke. [1] The EDSS is based on a neurological examination by a clinician. However, a number of versions have been developed which enable patient self-administration. [3]
EDSS can refer to: Elmira District Secondary School , the high school serving the town of Elmira, Ontario, Canada and the surrounding area Expanded Disability Status Scale , a medical scale to monitor the disability changes in multiple sclerosis
The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies ...
John Francis Kurtzke (September 14, 1926 – December 1, 2015) was a neuroepidemiologist and Professor of Neurology at Georgetown University who is best known for his creation of the Expanded Disability Status Scale and for his research on multiple sclerosis (MS). [1]
This age-weighting function applies only to the calculation of DALYs lost due to disability. Years lost to premature death are determined from the age at death and life expectancy. The Global Burden of Disease Study (GBD) 2001–2002 counted disability adjusted life years equally for all ages, but the GBD 1990 and GBD 2004 studies used the ...
The MSE either assesses the quality of a predictor (i.e., a function mapping arbitrary inputs to a sample of values of some random variable), or of an estimator (i.e., a mathematical function mapping a sample of data to an estimate of a parameter of the population from which the data is sampled).
Algorithms for calculating variance play a major role in computational statistics.A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values.
The mental status examination (MSE) is an important part of the clinical assessment process in neurological and psychiatric practice. It is a structured way of observing and describing a patient's psychological functioning at a given point in time, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and ...
