Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Asymmetric rest tremor is one of the main features of patients diagnosed with scans without evidence of dopaminergic deficit (SWEDD). Clinical and neurophysiological evidence suggests a dystonic origin of this tremor, although the underlying pathophysiology is still unclear. Dystonic tremor has a great tendency to vary with different postures or voluntary motor tasks. Here, we performed a phenomenological analysis of tremor in 14 patients with normal scans and in 14 tremor-dominant Parkinson's disease (PD) patients by assessing the presence of writing tremor. The Wilcoxon-Mann-Whitney's test revealed that patients with normal scans exhibit writing tremor more frequently, regardless of the side mostly affected by motor disturbances in handwriting (P < 0.01) and drawing (right hand: P = 0.01; left hand: P < 0.05). Our findings show that patients with asymmetric rest tremor and normal scans, contrarily to PD patients, present more commonly action tremor during writing tasks. This feature may thus be helpful to distinguish the two conditions.
