Psychiatry is the only medical specialty that lacks clinically applicable biomarkers for objective evaluation of the existing pathology at a single-patient level. On the basis of an original translational equilibriometric method for evaluation of movement patterns, we have introduced in the everyday clinical practice of psychiatry an easy-to-perform computerized objective quantification of the individual locomotor behaviour during execution of the Unterberger stepping test. For the last 20 years, we have gradually collected a large database of more than 1000 schizophrenic patients, their relatives, and matched psychiatric, neurological, and healthy controls via cross-sectional and longitudinal investigations.

Introduction: Previous studies have suggested that the two opposite poles of psychomotor disturbances in unipolar depression (UD) - retardation and agitation - require different treatment strategies as the psychomotor overactivation requires an augmentation of the antidepressant therapy with mood stabilizers and/or atypical antipsychotics.

Objective: The aim of the present study was to objectively identify and measure the psycho-motor disturbances in UD using differentiation between activity and reactivity.

Material And Methods: An equilibriometric movement pattern analysis system that allows differentiation between psychomotor activity and reactivity was applied in 58 unipolar depressive patients and 76 healthy controls.
