Parkinson’s Progression Markers Initiative (PPMI)

Sponsor: The Michael J. Fox Foundation

Duration: 5+ years (up to 13 years total)

Brief summary: PPMI aims to better understand how Parkinson’s disease (PD) starts and changes over time. The study follows groups of people, including those both with and without Parkinson’s disease. The information from this study could transform how we diagnose, treat, and potentially prevent PD.

Basic eligibility criteria:

  • Individuals who are at least 60 years old and are: First-degree family members (parent, child, sibling) of a person with Parkinson’s OR
    • People who have risk factors for the development of PD (known genetic mutation, loss of smell, history of physically acting out dreams during sleep, and others)
  • Individuals who are least 30 years old and are:
    • People with Parkinson’s who have been diagnosed within the last two years and are not currently taking standard PD medications OR
  • People without Parkinson’s and no known risk to act as a comparison group

What: The Speech Science and Disorders Lab is conducting a research study to develop a technology-enabled tool for remote assessment and monitoring of voice changes and guiding self-administered speech exercises

Why: Abnormal voice is a hallmark feature of many neurologic diseases.  Finding an efficient and reliable way of registering voice changes can not only help patients to self-monitor their health but also help clinicians to deliver appropriate and timely care.

How: Participants will complete a self-administered 1-hour remote study session every 1-2 months for up to 12 months.  Participation requires: (1) a self-supplied electronic device such as a computer or tablet with reliable internet access and a video camera, (2) a microphone for voice recording, and (3) a headphone for sound playback.  Participants will access the study via an online program.  In each session, participants will complete a few questionnaires and perform various speaking tasks.  All procedures involve minimal risks.

Where: A quiet environment of participant's own choice (e.g., participant's home).


  • Are 18 years or over
  • Speak American English as your first and primary language
  • Are diagnosed with a neurologic disease such as ALS, Parkinson's disease, Huntington's disease, muliple sclerosis, cerebellar ataxia, etc.
  • Have no history of other neurologic disorders than your primary diagnosis

Compensation: $15 compensation for each remote study session

For more information, please contact: 785-864-0053 or 

Purpose: Researchers are studying mild exercises for sleep quality in people with Parkinson's disease.  

Who: Ages 40-75 years, Diagnosis of idiopathic PD


  • Mild exercise at home for 12 weeks
  • 15 to 20 minutes per exercise session
  • Online group meeting once per week

Compensation: Up to $100 ($50 per visit to the research lab)
