METHODS: We analyzed data from a large clinical trial in PSP-Richardson's syndrome (AL-108-231) to calculate minimal clinically important worsening. This was defined as the difference in mean change of PSPRS in subjects rated "a little worse" and those rated "unchanged" on the Clinicians' Global Impression of Change Scale. A multivariate analysis using logistic regression assessed the relationship between clinical worsening, PSPRS, depression, and activities of daily living. RESULTS: The minimal clinically important worsening on the PSPRS was 5.7 points, corresponding to the mean decline over 6 months in the trial. Changes in activities of daily living and PSPRS were significantly associated with clinical worsening. CONCLUSIONS: Clinically meaningful change is measurable on the PSPRS over 6 months. © 2016 International Parkinson and Movement Disorder Society. date: 2016-10-06 date_type: published official_url: https://doi.org/10.1002/mds.26694 full_text_type: other pmcid: PMC5215805 language: eng article_type_text: Journal Article verified: verified_manual elements_id: 1574635 doi: 10.1002/mds.26694 lyricists_name: Lees, Andrew lyricists_id: AJLEE60 actors_name: Bracey, Alan actors_id: ABBRA90 actors_role: owner full_text_status: restricted publication: Movement Disorders volume: 31 number: 10 pagerange: 1574-1577 event_location: United States issn: 1531-8257 citation: Hewer, S; Varley, S; Boxer, AL; Paul, E; Williams, DR; AL-108-231 Investigators; (2016) Minimal clinically important worsening on the progressive supranuclear Palsy Rating Scale.
