Unified Dyskinesia Rating Scale (UDysRS)   [1] 
Mean (Standard Deviation)
Unit of measure:  Units on a scale
 Number Analyzed 38 participants 37 participants 75 participants
Total Score 41.2  (10.32) 40.2  (13.06) 40.7  (11.68)
Total Objective Score (Parts III, IV) 15.9  (7.00) 18.1  (7.99) 17.0  (7.53)
[1]
Measure Description: The UDysRS is a dyskinesia rating scale that evaluates involuntary movements associated with PD; the UDysRS consists of the following sub-parts: IA, IB, IIA, IIB, III, and IV. The total score is the sum of all individual sub-parts, and scores for this measure can range from 0-104. The total objective score is the sum of Part III (which measures objective impairment) and Part IV (which measures objective disability), and scores for this measure can range from 0-44. For both the total score and total objective score, a higher score indicates more severe PD.

Measure Description:

A PD home diary was used to score 5 different conditions in 30-minute intervals: ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

Total time with dyskinesia includes ON time with non-troublesome and troublesome dyskinesia.

Measure Description: The MDS-UPDRS Parts I, II, III, and IV examined non-motor experiences of daily living, motor experiences of daily living, motor examination, and motor complications, respectively. Each Part contains items/questions, each rated on a scale from 0 (normal) to 4 (severe). The range of total scores for each Part is as follows: Part I, 0-52; Part II, 0-52; Part III, 0-132; Part IV, 0-24. Combined Parts I, II, and III is the sum of scores from Parts I, II, and III and has a scale range of 0-236. Parts 4.1 and 4.2 each has a scale range of 0-4. Higher scores indicate more severe PD.
