Definitions for "Intention Tremor"
Tremor occurring when the person attempts voluntary movement.
In disease of the cerebellum or its connections, the velocity and force of movements are not properly controlled. If a limb overshoots or undershoots its target, then the error is corrected with a series of jerky secondary movements in which the finger (or toe) moves side-to side before it finally reaches the target. These little movements have been called intention tremor. (In addition, patients with cerebellar damage or damage to the superior cerebellar peduncle may show a much wider-range, flapping tremor whenever they try to activate limb muscles.)
Occurs during voluntary movement.
