Abstract
An important part of epidemiologic and genetic studies of essential tremor (ET) is an assessment of tremor severity. Clinical rating scales are semiquantitative and computerized tremor analysis, available at tertiary medical centers, is not transportable into the field. As part of an epidemiologic study, we modified the Klove-Matthews Motor Steadiness Battery, collecting objective quantitative data on tremor severity in patients with ET and control subjects.

NHST and GTST total scores were correlated significantly with the tremor disability questionnaire score (r = 0.63, p = 0.001 and r = 0.49, p = 0.016), total tremor score (tremor examination, r = 0.68, p<0.001 and r = 0.41, p = 0.005), performance-based test score (r = 0.81, p<0.001 and r = 0.65, p = 0.001), and quantitative computerized tremor analysis results (for example, spiral drawing, r = 0.62, p = 0.01 and r = 0.58, p = 0.019).
