Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Modified FTM(Fahn-Tolosa-Marin) Essentials Tremor Rating Scale, Sum of All Essential Rating Tremor Scales Including Voice Tremor
Time Frame: Hour 1
The modified FTM sum of all essential rating tremor scales including voice tremor includes: the tremor rating taken for the left & right hands individually at rest, with posture (arms outstretched), with action (finger to nose). It also includes an evaluation of voice with scores for AAA & EEE sounds, an action evaluation of left & right hands pouring, bringing liquids to mouth, drawing large & small spirals. Scores for indiviuals items range from 0 (no tremor) to 4 (severe tremor). The sum ranges from 0 (no tremor) to 72 points (higher amplitude/more tremors).
