Study Recruitment

We are seeking participants for the following studies.

Developmental Screening: Sickle Cell Disease

We are studying children 0-3 years old to identify the rate of developmental delay among young children with sickle cell disease to increase screening and referral to therapeutic intervention services. Data will be collected throughout 3 study visits involving play activities to see how the child is moving and learning and some surveys.

Families will be compensated for their time in the form of gift cards for up to $150 (maximum of 3 visits). To learn more about this study, please contact Catherine Hoyt, PhD, OTD, OTR/L, FAOTA.



We are seeking children who may have:

  • Had a stroke early in life
  • Has hemiparesis (weakness or poor control of one side of his or her body)
  • Will be between 8-36 months old while receiving treatment

We are studying the differences between constraint-induced movement therapy (CIMT) in two high-intensity dosages, and comparing it to traditional treatments for children with hemiparesis (one hour/week of therapy). Your child will be asked to wear a cast for 3 1/2 weeks on their “unaffected” arm and hand. Your child will be randomly assigned to 1 of 3 therapy groups (6 hours of I-ACQUIRE therapy, 3 hours of I-ACQUIRE therapy, or continue with current therapy). Caregivers and their child will be asked to participate in 3 assessments (pre-, post, and 6-month post-assessment).

Families will be compensated for their time with a gift card. For additional questions or concerns, please contact Catherine Hoyt, PhD, OTD, OTR/L, FAOTA, Alyssa Smith, Maria Coxon, OTD, OTR/L, or Jianna Fernandez, OTD, OTR/L.

Exploring Cognition

The purpose of this research study is to understand characteristics of self-perceived concerns on thoughts, attention, and memory by using self-report questionnaires. You might qualify if you are 45 or older, speak English and live in the community. Participation will take 30-40 minutes. Participants will answer questions via text, email, or in-person. A $20.00 gift card is provided. Contact [email protected] or 314-286-2096.


Understanding Engagement in Research, Clinical Care and Community Services Among People of Color with Parkinson Disease

We will conduct semi-structured interviews with Black or African American people with Parkinson Disease (PD), care partners of Black or African American people with PD, and health professionals who treat predominantly Black or African American people with PD. The goal of the interview will be to understand factors that influence the ability and willingness of Black and African American people with PD in the St. Louis area to engage with PD specialty clinical care, research and community services.

MRI Left Hand Study

The purpose of this study is to use MRI to understand how your brain controls your left hand, and how that changes after a nerve injury. Single site visit for half a day (about 5 hours). Participants will receive $110 for completing the study. Participants must be right handed, age 18+, with a nerve injury to their right hand, arm, or shoulder and no other conditions that impair their movement. Participants must not have cardiac pacemakers, aneurysm clips, spinal stimulators, or any other non-removable metal implants. Please contact us at [email protected], 314-747-7724, or register at


OT Survey for Practitioners

Researchers in the Washington University Program of Occupational Therapy are conducting a survey to help with the development of an iPad app to assess children’s handwriting. This survey will help us understand the assessment needs of educators and occupational therapy practitioners. Participants must be a clinician or educator who works with children ages 6-8. The survey will take 5-9 minutes to complete. People who complete the survey will be entered into a pool to win a $50 gift card.
