Abbreviations: SD, standard deviation; CI, confidence interval; SEM, standard error of the mean; FTM, Fahn‐Tolosa‐Marin Clinical Rating Scale for Tremor; TETRAS, the Essential Tremor Rating Assessment Scale.

^aPaired differences are shown for baseline versus 3‐month ratings.

^b P values were determined using the paired t test.

^cFTM composite = rest + postural + kinetic scores.

^dTETRAS composite = postural + wing‐beating + kinetic scores.
