Elizabeth: The Unified Parkinson Disease Rating Scale (UPDRS), provides a detailed evaluation tool for determining where a PWP stands in the progression of the disease. This scale, developed in 1987 and since refined, has supplemented the older and much less detailed Hoehn and Yahr rating system. The UPDRS system is divided into six sections: I. Mentation, Behavior and Mood II.Activities of daily living (ADL) III. Motor Examination IV. Complications of therapy V. Modified Hoehn and Yahr Staging (Five stages) VI. Schwab and England Activities of Daily Living Scale ( which assigns a percentage value to each degree of dependency that had been determined. Each of the these sections is divided into a number of different aspects of that part of the problems of PD. Each of these sub-categories in the first four sections includes a detailed rating scale from 0 to 4 for each item that the neuro can use to assess a patient. These cover all of those familiar things the neuro asks a PWP to perform, the finger taps, the walking, the rising from a chair, etc. Even a lay person can get a pretty good idea where a PWP stands by using this rating scale. (When I printed a copy of the scale it took 6 pages. It is quite detailed.) One source is: http://www.mssm.edu/neurology/wemove/pdrscale.html Martha Rohrer (CG for Neal 77/12} [log in to unmask]
