We study how infants learn to move and move to learn!

A special congratulations to our graduating lab members, Jeannie, Minami, and Lauren! 🎓 Whether continuing their studies in developmental psychology or entering the field of physical therapy as licensed professionals, we know these three graduates will make an incredible impact through their dedication to science and helping others. We are so proud of you all and wish you the very best in your next steps. Congratulations, Class of 2026! ✨

April has been an exciting month for our lab! 🌟 We want to celebrate Dr. Kari Kretch, principal investigator of the Learning Development & Rehabilitation Lab, for publishing her work on everyday positioning in infants with and without cerebral palsy.
Dr. Kretch utilized text message surveys to gain an accurate picture of what infants are doing at random intervals throughout the day, over two weeks of activity. Through her work, we learned that infants with cerebral palsy spend considerably more time lying on their backs, and considerably less time standing, compared to same-aged typically developing infants.

Here are some quick highlights of presentations from our lab members this spring! 🌟 From SoCal Minds to Dentistry Day, the Undergraduate Symposium, to the ASN Annual Conference, we are excited to share our latest advances & future directions in infant motor development. We’re so proud of our team for representing the lab and contributing to important conversations! 👏

This month, we had the joy of hosting wonderful families for a Family Park Day in honor of World Down Syndrome Day! 💙💛 Families swapped children’s books, enjoyed board games, and spent the afternoon playing with hula hoops, balls, and bubbles. Together, we also painted a special banner to commemorate the date we celebrated our Family Park Day! 🎨

We’re so grateful to the families who continue to support our lab — your presence makes this community so meaningful. We hope to see you all again soon! 🌼

October is in full swing, and we’re falling into new discoveries here at the Learning, Development, and Rehabilitation Lab! 🍁✨

This season, we’re highlighting our research and sharing a few of the amazing resources and communities we’ve connected with while learning from families of infants with Down syndrome. 💙

💬 What resources have made a difference for your family?

CURRENTLY RECRUITING!

Delays in independent walking restrict children’s participation in their homes and communities and limit learning opportunities that contribute to global development. Prior work has demonstrated that early practice stepping on a treadmill can accelerate and improve walking development in infants with Down Syndrome, who typically learn to walk about a year later than their typically developing peers. However, treadmill training has several limitations, including its passive nature and lack of variability, context, and motivation. Overground gait training with assistance of supported stepping devices (“gait trainers”) may be a promising adjunct to, or substitute for, treadmill training. This longitudinal study will examine the developmental trajectory of supported overground stepping and walking in infants with Down Syndrome to inform the development of a novel overground gait training protocol.
