Utilization of Target Ranges to Treat Persons With Parkinson's Disease by Objective Measurement Using the PKG

Utilization of Target Ranges to Treat Persons With Parkinson's Disease by Objective Measurement Using the Personal KinetiGraph® (PKG®) Compared to Standard of Care Assessment (TARGET-PwP)- A Randomized Controlled Trial

The main objective of this study is to evaluate whether persons with Parkinson's disease (PwP) whose Parkinson's disease (PD) symptoms are uncontrolled have improved clinical patient outcomes and quality of life when managed with the aid of objective measurement and use of PKG target ranges compared to PwP treated using only standard of care (SOC) (medical history, physical examination).

This is a randomized controlled trial (RCT) to compare the value of the Personal KinetiGraph® (PKG®) System and SOC vs. the SOC alone for treatment of PwP. The study aims to evaluate clinical outcomes, quality of life outcomes, health economic benefits, duration of controlled status, and need for additional PD treatment through 3 years follow-up of PwP specifically treated to a target range when using the PKG data in the clinical management of PD in routine clinical care compared to those managed with SOC alone. All subjects will be treated by Movement Disorder Specialists and General Neurologists with expertise in PD. Both groups will be recommended to undergo treatment changes until they reach a "controlled state" that is determined by either the clinician using SOC (PKG- Group) or using recommended target ranges for PKG scores and SOC assessments (PKG+ Group). Investigators will utilize standard available treatments to manage these PwP in both groups.
