Synonym: benign essential tremor, familial tremor. (05 Mar 2000) |
| passive tremor | A coarse, rhythmic tremor, 3-5 Hz frequency, usually confined to hands and forearms, that appears when the limbs are relaxed, and disappears with active limb movements; characteristic of Parkinson disease. Synonym: passive tremor. (05 Mar 2000) |
| volitional tremor | A tremor that can be arrested by a strong effort of the will. Synonym: intention tremor. (05 Mar 2000) |
| resting tremor | A coarse, rhythmic tremor, 3-5 Hz frequency, usually confined to hands and forearms, that appears when the limbs are relaxed, and disappears with active limb movements; characteristic of Parkinson disease. Synonym: passive tremor. (05 Mar 2000) |
| mercurial tremor | A tremor caused by chronic mercury poisoning. (05 Mar 2000) |
| persistent tremor | A tremor that is constant, whether the subject is at rest or moving. Synonym: continuous tremor. (05 Mar 2000) |
