Differences in MDS-UPDRS scores based on Hoehn and Yahr stage and disease duration: Results of a large international multicenter study of 3206 patients (the QUALPD study)
Objective: To analyze the MDS-UPDRS part I-IV scores and their differences based on Hoehn and Yahr stage (HY) and disease duration in a large cohort…Tremor amplitude detected by three-dimensional optical device provides good correlation to clinical rating scale
Objective: To examine the feasibility of using a three-dimensional (3D) optical device served as tremor amplitude detection, we determined correlation between its results and clinical…Gender and age-based differential item functioning (DIF) analysis of MDS-UPDRS
Objective: Test if DIF due to gender or age is present in MDS-UPDRS items. Background: Testing a rating scale for DIF is a core step…Digitizing tablet and Fahn-Tolosa-Marín tremor ratings have comparable minimum detectable change
Objective: To determine if a digitizing tablet is better than Fahn-Tolosa-Marín part B (FTM-B) ratings in detecting changes in essential tremor (ET) that exceed random…Patient reported outcomes in Parkinson’s disease (PRO-PD) rating scale validation
Objective: To evaluate whether a novel outcome measure, Patient-Reported Outcomes in Parkinson's disease (PRO-PD), correlates with disease duration, quality of life and established measures of…
