Answer

Resting tremor is assessed by having patients relax their arms in their lap while in a seated position. Having patients count aloud backward from 10 may help bring out the tremor. The arms should also be observed in an outstretched position to assess postural tremor, and kinetic tremor (tremor with voluntary movement) can be observed during the finger-to-nose test. Although a resting tremor is the tremor characteristic of Parkinson disease, many Parkinson disease patients also have some postural and/or kinetic tremor.
