Driving Performance of People With Parkinson's Using Autonomous In-Vehicle Technologies

Study Overview
=================
Brief Summary
-----------------
For drivers with Parkinson's Disease (PD), autonomous in-vehicle technologies may help mitigate functional deficits, improve driving performance, decrease driving errors and enhance their ability to stay on the road. Using a pretest/posttest design the investigators will quantify the use of In-vehicle Information Systems (IVIS) and Advanced Driver Assistance Systems (ADAS) during driving to illustrate how IVIS and ADAS may affect driving, and provide recommendations to drivers with PD, the clinical community and industry.

Eligibility Criteria
-----------------
Inclusion Criteria: Subjects diagnosed by a neurologist/ movement disorder specialist with clinically probable PD by Movement Disorders Society (MDS) criteria 25 Has mild or moderate disease severity, based on the MDS-Unified Parkinson's Disease Rating Scale for motor symptoms (hereafter referred to as the UPDRS section 3) in the on state of medications (i.e., one hour of taking PD medications) and the Modified Hoehn and Yahr disease severity scale Is representative of one of two PD groups based on age, i.e., participants with symptom onset between 35-64 years of age (younger onset), or participants with symptom onset between ages 65- 85 years (older onset) Currently driving with a valid license Meets the Florida state requirement for visual acuity of at least 20/50 in one eye, if one eye is blind or 20/200 or worse the other eye must be 20/40 or better (20/40 in at least one eye) and field of vision (130 degrees or more) Lives independently in the community Proficient in reading/speaking English A Montreal Cognitive Assessment (MoCA) score of 20 or higher Exclusion Criteria: Concurrent neurological conditions (e.g., stroke, seizures; dementia) Severe psychiatric (e.g., psychoses/ significant anxiety) or physical conditions (e.g., missing limbs) precluding full participation Use of psychotropic medications having adverse effect on mental/physical functioning Severe, unpredictable motor fluctuations Severe sleep difficulties.

Intervention Model: Single Group Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: PD Drivers Using AV Technologies On-road<br>Each driver will drive on-road, everybody will be exposed to two drives (Drive 1, Drive 2) one drive with and the other without in-vehicle technology. The order of technology (with vs. without IVIS or ADAS) and the order of the routes (Drive 1 vs. Drive 2) will be randomly allocated to control for order effects. | Other: PD Drivers Using AV Technologies On-road<br>* All drives will include events to assess the impact of in-vehicle information systems (IVIS) and advanced driver assistance systems (ADAS) on the driving performance (driving errors) of drivers with PD. For IVIS the investigators will include options to assess errors with lane maintenance (with and without the lane departure warning system) and signaling (with and without blind spot detection). For ADAS the investigators will include conditions to assess errors in speeding (with and without adaptive cruise control) and lane exceedances (with and without lane keeping assist).<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total number of driving errors | The evaluator will record the total number of driving errors by number and type (i.e., speeding, lane maintenance, and signaling) on a standardized data collection form. | 1 year up to study completion | 
| Type and number of driving errors | Type of driving errors include: speeding, lane maintenance and signaling on-road recorded by the evaluator, or via vehicle recorded kinematics and telematics (e.g., in-vehicle GPS to record speed). | 1 year up to study completion |
