Tremor amplitude is logarithmically related to 4- and 5-point tremor rating scales.
Tremor rating scales (TRSs) are used commonly in the clinical assessment of tremor, but the relationship of a TRS to actual tremor amplitude has never been quantified. Consequently, the resolution of these scales is unknown, and the clinical significance of a 1-point change in TRS is uncertain. We therefore sought to determine the change in tremor amplitude that corresponds to a 1-point change ...

متن کاملProperties of Equivalence Scales in Different Countries
Recent studies in high-income industrialized countries have shown that equivalence scales are income-dependent. We investigate whether this dependence also holds in poorer, services oriented countries, by considering the example of Cyprus. We also examine whether household economies of scale and relative children costs differ.
متن کاملWhy Semantic Differentials in Web-Based Research Should be Made From Visual Analogue Scales and Not From 5-Point Scales
In a Web experiment, participants were randomly assigned to 2 semantic differentials either made from discrete 5-point ordinal rating scales or from continuous visual analogue scales (VASs) with 250 gradations. Respondents adjusted their ratings with VASs more often to maximize the precision of answers, which had a beneficial effect on data quality. No side effects like differences in means, hi...
متن کاملSredišnja Medicinska Knjižnica Clinical Rating Scales Title: Clinical Rating Scales
In Parkinson's disease (PD) rating scales are used to assess the degree of disease-related disability and to titrate long-term treatment to each phase of the disease. Recognition of nonmotor symptoms required modification of existing widely used scales to integrate nonmotor elements. In addition, new scales have been developed for the assessment of nonmotor symptoms. In this article, assessment...
