Participate in a Study

The LARRS is currently enrolling volunteers with Parkinson’s disease and healthy control subjects for a study:
Increased cognitive effort during dual-tasking and its relationship with falls in Parkinson's disease

We want to know:
How much mental effort, measured by pupil dilation, is needed during dual-tasking, and is there a relationship between increased mental effort and falls in Parkinson’s disease.

We will record participant's pupil responses during concurrent cognitive and motor activities. This will take two hours. These pupil recordings are not invasive. If eligible, participants may be compensated $50 for this time.

  1. Are 60 years of age or older
  2. Have either a diagnosis of Parkinson's disease or no neurological condition at all
  3. Have no problems with eyes or pupils, except for corrective glasses or contact lenses
  4. Are English speaking
  5. Have no musculoskeletal problems which might affect standing and balance activities

The LARRS is currently enrolling volunteers with mild cognitive impairment and healthy control subjects for a study:
Can we detect problems with thinking functions before they emerge in older adults at risk of Alzheimer's disease?

We want to know:
Is it possible to use non-invasive neurophysiological measures as potential markers of subtle cognitive impairments in individuals who are at risk for developing Alzheimer’s disease?

We will record participants' brain waves, pupil dilation, and heart rate with non-invasive tools while engaging in different cognitive tests. This will take two hours. If eligible, participants may be compensated $50 for their time.

Individuals are eligible to participate if meeting the following criteria:

  1. Being cognitively intact, or having mild cognitive impairment
  2. Aged more than 60 years old
  3. Have no history of other neurological conditions
  4. Have no problems with eyes or pupils, except for corrective glasses or contact lenses
  5. Have no cardiac rhythm disorders

Can we detect small thinking impairments in adults with multiple sclerosis by measuring their pupil size?

We want to know:
Is it possible to use non-invasive neurophysiological measures as potential markers of subtle cognitive impairments in individuals who are at risk for developing and worsening cognitive impairment in multiple sclerosis?

We will record participants' pupil dilation with non-invasive tools while engaging in different cognitive tests. This will take two hours. If eligible, participants may be compensated $50 for their time.

Individuals are eligible to participate if meeting the following criteria:

  1. Being cognitively intact, or having mild cognitive impairment
  2. Aged 18-65 years old
  3. Have no history of other neurological conditions
  4. Have no problems with eyes or pupils, except for corrective glasses or contact lenses

The LARRS is currently enrolling commercial truck drivers of any age for a study:
Assessing andImproving the Cognitive and Visual Driving Fitness of Commercial Truck Drivers

What we want to accomplish:
Assess drivers’ cognitive and visual fitness, establish the usefulness and effectiveness of these tests to drivers before embarking on the journey, identify potential risk factors that contribute to unsafe driving, and evaluate the effect of an intervention program to improve reduced visual, cognitive, and driving skills.

The subjects will need to come in for a visual, cognitive and mobility testing evaluation. This will take two hours. The participants will be asked to come in once a year for three years. We will give them useful information, including height, weight, BMI, that will assist them in any concerns we may find.

Results will only be kept with the research team. Our goal is to help our participants remain safer drivers longer.

Individuals are eligible to participate if they meet thefollowing criteria:

  1. Are 18 years of age or older,
  2. Have a valid Commercial Driving License.

Compensation will be provided!

Activities and Updates

Hannes Devos and Melike Kahya from LARRS are presenting a special symposium at the annual conference of the American Congress of Rehabilitation Medicine in Dallas Sept 30-Oct. 3.

The LARRS driving simulator has been fitted with hand controls and spinner knob. Hand controls enable braking and acceleration by hands while the steering spinner knob allows one-handed steering.

Two LARRS students presented their poster at the American Physical Therapy Association Combined Section Meetings 2018 in New Orleans, La in February 2018. The poster by Melike Kahya and Kevin Williams is titled "Does Pupillometry Reflect Change in Postural Control: A Proof-of-Concept Study."
