Calibration of unified Parkinson's disease rating scale scores to Movement Disorder Society-unified Parkinson's disease rating scale scores.

摘要: The aim of this study was to develop formulas convert the UPDRS Movement Disorder Society (MDS)-UPDRS scores. MDS-UPDRS is a revision with sound clinimetric properties. Reliable recalculate scores into equivalents are pivotal practical transition and definitive adoption MDS-UPDRS. were collected on 875 PD patients. A developmental sample used regress corresponding based three H & Y groupings (I/II, III, IV/V). Regression weighting factors intercept terms provided for conversions be tested in validation sample. Concordance between true Part those derived from compared using Bland-Altman's plots Lin's concordance coefficient (LCC). Significant UPDRS-estimated achieved Parts II (Motor Experiences Daily Living) (LCC = 0.93) III Examination) 0.97). resulted mean differences estimated less than 1 point both III. not I IV (Non-motor Living Complications Therapy). Formulas allow archival individual patient data accurately transferred Because collects much more extensive information UPDRS, because structured differently two versions, old ratings these parts cannot converted. © 2012 Society.
