Outcome Measures
Primary Outcomes (1)
Modified FTM(Fahn-Tolosa-Marin) Essentials Tremor Rating Scale, Sum of All Essential Rating Tremor Scales Including Voice Tremor
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).
