Using Advanced Driver Assistance Systems (ADAS) as an Intervention Strategy for Drivers With Parkinson's Disease

Not Applicable

Completed

• Conditions: Parkinson Disease; Driving Impaired

• Registration Number: NCT03195608
• Lead Sponsor: Western University, Canada

Brief Summary

Parkinson's disease (PD) impacts an individual's fitness to drive in a number of ways that increase the crash risk in this population. Current vehicle automation technologies are available, that although designed for the general public, may help drivers with PD stay on the roads longer and safer than currently possible. Using a driving simulator (a safe and cost-effective alternative with no impact on licensing for participants), this study will investigate the feasibility and preliminary efficacy of utilizing in-vehicle technology (i.e., a simulated lane change assistance system) to address critical driving errors in individuals with mild to moderate Parkinson's disease.

Primary Outcome Measures

Name	Time	Method
Change in number of lane maintenance errors from baseline to post-test 1(4 weeks) and post-test 2 (6 weeks)	Baseline, 4 weeks, and 6 weeks	Refers to the lateral position of the vehicle in the lane.
Change in number of visual scanning errors from baseline to post-test 1(4 weeks) and post-test 2 (6 weeks)	Baseline, 4 weeks, and 6 weeks	Visual scanning is defined as eye movement and turning of the neck and head (e.g. glances, look sideways at an intersection, look at mirrors) to detect oncoming objects
Change in number of signalling errors from baseline to post-test 1(4 weeks) and post-test 2 (6 weeks)	Baseline, 4 weeks, and 6 weeks	Refers to the proper use of turning signals during lane changes
