Shaky drawing: what is the rate of decline during prospective follow-up of essential tremor?

ABSTRACT:

Objective

Few studies have attempted to estimate the rate of decline over time in essential tremor (ET). The study objectives were to: (1) measure change, deriving a single summary measure for the entire group, and relate it to a commonly used clinical rating scale (ie, yearly change in points on that scale); (2) to assess change as a function of baseline clinical characteristics and (3) to answer the basic clinical question-is change perceptible/obvious during the follow-up of ET cases?

Setting

Prospective collection of longitudinal data on ET cases enrolled in a study of the environmental epidemiology of ET at Columbia University Medical Center (2000-2008).

Participants

116 unselected ET cases.

Interventions

Each case underwent the same evaluation at baseline
