Quantitative Clinical Evaluation of Parkinsonism Based on Visuomotor Tracking and Tracing

Conference paper

Abstract

The motor deficits of patients with Parkinson’s disease (PD) are evaluated periodically, in order that optimal pharmacological treatment be prescribed. To date, such an evaluation is based on crude observations of tremor, rigidity, and postural deviations, which together constitute a classification of patients into four categories on the Hoehn and Yahr scale [3]. In addition to clinical evaluation of patients with known PD, early detection of parkinsonism in new patients is gaining importance. New preventive treatments are becoming available, which may delay progression of the disease [5], and a decision whether to begin such treatment can no longer be based on crude clinical observations. Thus, a sensitive, reliable, and quantitative method for the assessment of parkinsonism is required.
