Primary orthostatic tremor: analysis of three cases.
Primary orthostatic tremor (POT) is a rare form of tremor characterized by unsteadiness and quivering of lower extremities while standing. These symptoms relieve when sitting or reclining It is much less apparent when leaning against an object or during walking. The rhythmic tremor activity with a frequency of 13-18 Hz can be obtained electromyography recordings. Here we report three cases that have typical clinical and electrophysiological findings of POT.
