A Slow Orthostatic Tremor of Primary Origin

Coffeng, Sophie M.; Hoff, Jorrit I.; Tromp, Selma C.

Background: Orthostatic tremor (OT) is a high‐frequency tremor (13–18 Hz) present in the legs when standing. Underlying disease is found in one‐third of OT patients.
Case report: We describe an 86‐year‐old man with progressive shaking of the legs while standing, which disappears immediately after sitting down or while walking. Polymyography confirmed a tremor of the legs (10–11 Hz) while standing. Magnetic resonance imaging (MRI) and neurologic examination showed no underlying disease.
Discussion: Primary OT can appear at a lower frequency of 10–11 Hz.
