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.
