Advanced technique for characterization of balance disorders in multiple sclerosis: posturography

Balance impairment is one of the most common symptoms in people with multiple sclerosis (MS), even found in the early stages. In this chapter, we present an advanced technique to characterize balance disorders in MS using a static force platform, called static posturography. Many linear (temporal and spectral) parameters and nonlinear indicators can be extracted from the stabilometric signals and are able to provide new diagnostic elements for the management, in particular with the possibility of predicting disability progression, and to improve the understanding of the mechanisms involved in the system for balance regulation in MS.
