Figure 3.

Employment, disability and symptomatic medication use by tremor severity. The figure depicts the proportion of registrants indicating unemployment, disability status and use of symptomatic medication by two different measures of tremor severity. The upper figure depicts tremor severity by the Tremor and Coordination Scale (TACS) scores derived from the North American Research Committee on Multiple Sclerosis (NARCOMS) semiannual updates. The scores denote mild (TACS=2), moderate (TACS=3), severe (TACS=4) and totally disabling (TACS=5) tremor. The lower figure depicts tremor severity by dividing responses on the Tremor Related Activities of Daily Living scale into quartiles of severity ranging from 1 (least severe) to 4 (most severe).
