Table 1:

Subject characteristics, sorted by the amount of power in the tremor band (from least to most severe). Dur., Hand., Ht, Wt, and Family Hist represent the duration of the disorder in years, handedness, height, weight, and family history of ET, respectively. The TETRAS score is divided into scores for activities of daily living, performance, and a total score. Power was calculated during the data analysis and represents the mean total power in acceleration in the tremor band (4–12 Hz), averaged over all trials (see Methods). NK stands for “not known.”
