Hoehn and Yahr Staging Scale

Published in 1967, the Hoehn and Yahr staging scale has become the most commonly applied tool for assessment of PD patients. It is an ordinal scale that classifies disease status into five stages. It contains some ambiguities but possesses acceptable interrater reliability and convergent validity.
