The applications of posturography in selected neurological disorders

Abstract

Posturography is one of the objective methods of evaluating human balance. Human balance is the ability to maintain a vertical center of mass (COM) in the support area (base of support – BOS). COM in a homogeneous gravitational field coincides with the center of gravity (COG). The postural control system (PCS) maintains the COG projection in the support area and counteracts the external forces (gravity and inertia force) that destabilize the posture of the human body. Minimizing body deflection is controlled by the central nervous system (CNS). External stimuli are received through visual, atrial, proprioceptive and exteroceptive systems. The information is transmitted to the CNS, which, means of the feedback system, controls the motion system to minimize the risk of falls. The aim of this work is to present the types of posturography: static, dynamic, and follow-up posturography, their use in the objective diagnosis of imbalances, as a tool for rehabilitation and for monitoring the progress of treatment in Parkinson’s disease and patients after stroke.
