| familial tremor | <neurology> A neurologic disorder that runs in families and manifests as tremor which typically increases with purposeful movements. Stimulant use can increase tremor. (27 Sep 1997) |
| kinetic tremor | <neurology> A tremor which arises or which is intensified when a voluntary, coordinated movement is attempted. (18 Nov 1997) |
| fine tremor | A tremor in which the amplitude is small and the frequency is usually greater than 12 Hz. (05 Mar 2000) |
