Current Primary Outcome Measures ICMJE |
Hauser Diary [ Time Frame: Day 29 ] The Hauser Diary is a validated and commonly used patient-self-report home diary to assess motor symptoms in PD. It asks patients to characterize their predominant motor states in 30-minute intervals as Asleep, OFF, ON without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

Current Secondary Outcome Measures ICMJE |
Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) [ Time Frame: Day 29 ] The MDS-UPDRS evaluates various aspects of Parkinson's disease and has four parts: Part I (Non-motor Aspects of Experiences of Daily Living), Part II (Motor Aspects of Experiences of Daily Living), Part III (Motor Examination), and Part IV (Motor Complications). The MDS-UPDRS evaluates various aspects of Parkinson's disease and has four parts: Part I (Non-motor Aspects of Experiences of Daily Living), Part II (Motor Aspects of Experiences of Daily Living), Part III (Motor Examination), and Part IV (Motor Complications).
Each parkinsonian sign or symptom on the MDS-UPDRS is rated on a 5-point scale (ranging from 0 to 4), with higher scores indicating more severe impairment. The maximum total UPDRS score is 199, indicating the worst possible disability from PD.
