Abstract :
Random-step-tracking test data from 15 Parkinson´s disease patients are analyzed using step-response and phase-plane analysis. Correlation analysis is applied to investigate the relationship between three step-response measures and two phase-plane measures. Results indicate that reasonable estimates of the two of the step-response measures can be obtained from the phase-plane measures, but the third measure should be computed directly from the data.<>
