Multidimensional Phenotyping of Orthostatic Tremor and Orthostatic Myoclonus: Baseline Findings from a Longitudinal Clinical Study

This study presents the first structured multidimensional phenotyping of orthostatic tremor and orthostatic myoclonus, integrating clinical, electrophysiological, comorbidity, functional, and treatment domains. Findings demonstrate diagnostic overlap and support multidimensional approaches for refining classification and guiding individualized management across orthostatic hyperkinetic syndromes.
