Anticipatory Postural Adjustments and Dynamic Asymmetry of Voluntary Movement

Abstract

Anticipatory postural adjustments (APA) associated with intentional movement were studied in relation to dynamic asymmetry of the movement (bilateral movements, or unilateral ones with and without an added inertia), which integrates the effect of movement on the body structure. Three methods were used simultaneously: local movements were studied by means of electromyography and accelerometry, and general body movements were studied using a force platform.
