A retrospective study of the clinical and electrophysiological characteristics of 32 patients with orthostatic myoclonus.

ABSTRACT:

Objectives

To review the electrophysiological and clinical characteristics of 32 patients with orthostatic myoclonus (OM), a relatively newly identified movement disorder, and compare these characteristics to those of primary orthostatic tremor (OT) patients and patients with similar gait and balance complaints without either hyperkinesia diagnosed during the same 30-month period.

Methods

The database of the Mayo Clinic Florida Movement Disorders Electrophysiology Laboratory (MDEL) was searched for all patients referred for possible OM or OT from 6/2010 to 12/2012. All available clinical records and archived surface electromyographical data for these patients were reviewed and analyzed.

Results

32 patients with OM (mean age 74 years), 8 with primary OT (mean age 71),
