Outcome Measures

Primary Outcomes (8)

• Change From Baseline in MDS-UPDRS Part III Total Score

  Clinically significant changes in MDS-UPDRS Part III. The Movement Disorder Society - Unified Parkinson Disease Rating Scale, or MDS-UPDRS, is a four-part rating tool used to gauge the progress of Parkinson's disease in patients. Part III tests Motor Examination, which tests speech, facial expression, rigidity, finger and hand movement, pronation-supination movements of hands, toe tapping, leg agility, arising from chair, gait, freezing of gait, postural stability, posture, global spontaneity of movement, postural tremor of the hands, kinetic tremor of the hands, rest tremor amplitude, constancy of rest tremor, dyskinesias impact and Hoehn and Yahr stage (18 items total). Each item is rated from 0-4: 0 (normal), 1 (slight), 2 (mild), 3 (moderate), and 4 (severe). The Part III score ranges from 0 - 132; 32 and below is mild, 59 and above is severe. The total MDS-UPDRS Parts I-IV score ranges from 0 (no disability) to 260 (total disability). Higher values represent a worse outcome.

• Change From Baseline in MDS-UPDRS Part II Total Score

  Clinically significant changes in MDS-UPDRS Part II.The MDS-UPDRS scale refers to Movement Disorder Society - Unified Parkinson Disease Rating Scale, and it is a rating tool used to gauge the course of Parkinson's disease in patients. The MDS-UPDRS scale consists of 4 segments. Part II tests "Motor Aspects of Experiences of Daily Living". Each answer to the scale is evaluated by the principal investigator during the study visit. Some sections of the MDS-UPDRS scale require multiple grades assigned to each extremity. There are 13 items included in Part II. Part II score ranges from 0 - 52; 12 and below is mild, 30 and above is severe. Each item has 0-4 ratings: 0 (normal), 1 (slight), 2 (mild), 3 (moderate), and 4 (severe). The total score ranges from 0 to 260, with 0 indicating no disability and 260 indicating total disability. Higher values represent a worse outcome.
