This binary classification of movement disorders is based on the observed phenomenology, etiology, and topography. Practitioners and researchers may be confounded by this approach to classification and may prefer instead to use clinical impressions. Methods of data analysis, including linear and logistic regression, linear discriminant function analysis, factor analysis, inverted factor analysis, tree approaches, dynamic clusters analysis, and principal component analysis, may facilitate the classification of movement disorders.
