The Center for Research and Education on Accessible Technology and Experiences (CREATE) recently hosted its Spring 2025 Research Showcase and Community Day, bringing together researchers, industry leaders, and community members dedicated to advancing accessibility. Co-sponsored by HuskyADAPT, the event highlighted cutting-edge work that bridges technology and inclusion.

Our lab was proud to be part of the showcase, with several students and collaborators presenting their research. Alisha Bose presented a poster on How Does Clinical Presentation Impact Gameplay in Early Intervention? This project explored how children’s unique needs influence their interaction with accessible play tools like the Switch Kit.

Madeleine McCreary presented Kicking it Off: Do Toddlers with Disabilities Activate Leg Muscles When Driving with a Joystick? This study examined leg muscle activation in toddlers using powered mobility devices to inform interventions that support play and development.

Mia Hoffman, Spencer Hensley, and Katie Belen Leija presented Mobility Aids to Support Independent Play for Young Children with Down Syndrome. Their work evaluated how mobility devices support early movement and play in children with Down Syndrome.

Alexandra (Sasha) Portnova showcased the H.A.T. – Hand Assessment Tool, a camera-based tool that measures finger range of motion to support hand therapy practices.

These projects reflect CREATE’s mission: to make technology accessible and to make the world accessible through technology.

Celebrating Our Research Trainees at the 2025 UW Undergraduate Research Symposium

The University of Washington Undergraduate Research Symposium is an annual, day-long celebration of undergraduate achievement in research, scholarship, and creative expression. This year, we are proud to highlight the outstanding contributions of our lab’s research trainees who shared their innovative work with the broader academic community.

Alisha Bose delivered a compelling podium presentation titled “How Does Clinical Presentation Impact Gameplay in Early Intervention?” Her research explores how different clinical profiles may influence the way children engage with therapeutic play, contributing valuable insights to the field of accessible design.

Katie Leija presented a poster on “Impact of Powered Mobility Device Seat Design on a Young Child’s Exploration,” examining how adaptive seating affects mobility and interaction in young children using powered mobility devices.

Spencer Hensley shared his work through a poster presentation titled “Effects of Mobility Aids on Muscle Activity in Kids with DS,” which investigates how different mobility aids influence muscle engagement during play in children with Down syndrome.

We are incredibly proud of Alisha, Spencer, and Katie for their dedication and creativity. Their projects reflect the core mission of the Neuromechanics & Mobility Lab—engineering to enhance human mobility, play, and exploration. Through their work, they are helping to advance inclusive design and accessible technology that empowers individuals of all abilities.

Members of the Neuromechanics and Mobility Lab has a busy week attending the 2025 Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) Conference, held as part of RehabWeek 2025 from May 12-16 in Chicago, IL.

RehabWeek is a premier, week-long event that brings together multiple conferences in the field of rehabilitation technology. It fosters cross-disciplinary collaboration and innovation among researchers, clinicians, and industry professionals. Our lab was proud to be part of this vibrant community, with several members presenting their research and contributing to the ongoing dialogue on the future of rehabilitation science.

Two of our PhD students, Mia Hoffman and Madeleine McCreary, participated in the RESNA Student Scientific Paper Competition and presented their work during the Student Scientific Paper Platform session. Mia presented her research titled “Measuring Early Intervention Providers’ Use of a Novel Switch-Accessible Play Kit,” while Maddie shared findings from our lab’s Early Mobility & Play research in her talk, “Kicking it off: Do toddlers with disabilities activate leg muscles when driving with a joystick?”

Mia Hoffman also led a session on Play and Recreation in Assistive Technology titled “Switch It Up: From Adapted Toys to Therapeutic Gaming.”

Alexandra (Sasha) Portnova-Fahreeva presented a poster titled “Evaluating the Effects of Noninvasive Spinal Stimulation on Gait Parameters in Cerebral Palsy via Markerless Motion Capture” sharing findings from our lab’s Spinal Neuromodulation research. She also participated in the RESNA Student Design Challenge with her project, “H.A.T. – A Camera-Based Finger Range-of-Motion Hand Assessment Tool to Enhance Therapy Practices” where she and her team received honorable mention.

Katie Landwehr-Prakel presented a poster on “Cardiovascular Load of Using a Walker-Based Exoskeleton in Children with Cerebral Palsy,” and placed in the top 10 of the Fast Forward Poster Competition.

We are especially proud to share that Mia Hoffman was awarded 1st place and Madeleine McCreary received 2nd place in the Student Scientific Paper Competition. Congratulations to both for their outstanding work and well-deserved recognition.

We’re incredibly proud of our team’s contributions and accomplishments at RehabWeek 2025!

Journal article in Gait & Posture

Children with cerebral palsy (CP) have an injury to the central nervous system around the time of birth that affects the development of the brain and spinal cord. This injury leads to changes in gait neuromechanics, including muscle activity and joint kinematics. Transcutaneous spinal cord stimulation (tSCS) is a novel neuromodulation technique that may improve movement and coordination in children with CP when paired with targeted physical therapy.

Example kinematics and muscles activity at each assessment timepoint for P03’s more-affected side. A) Sagittal-plane hip, knee, and ankle kinematics over the gait cycle. Horizontal colored lines indicate where there were significant changes in kinematics over each phase of the study based on statistical parametric mapping (p Aim: How does the combination of tSCS and short-burst interval locomotor treadmill training (SBLTT) affect individual gait neuromechanics in children with CP?

Methods: Four children with CP (4–13 years old), received 24 sessions each of SBLTT only and SBLTT with tSCS (tSCS+SBLTT). Clinical assessments of spasticity and passive range of motion (PROM), as well as biomechanical assessments of joint kinematics, musculotendon lengths, and muscle activity were recorded during overground, barefoot walking. Assessments were taken before and after each intervention, and 8-weeks later.

Results: The combination of tSCS+SBLTT led to greater increases in hip and knee extension than SBLTT only for three participants. Three children also became more plantarflexed at the ankle during stance after tSCS+SBLTT compared to SBLTT only. While tSCS+SBLTT reduced spasticity, these changes were only weakly correlated with changes in musculotendon lengths during gait or PROM, with the largest correlation between change in gastrocnemius operating musculotendon length during fast walking and gastrocnemius spasticity (R2 = 0.26) and change in plantarflexor PROM and gastrocnemius spasticity (R2 = 0.23).

Interpretation: Children with CP used a more upright, less crouched posture during gait after tSCS+SBLTT. Large reductions in spasticity after tSCS+SBLTT were only weakly correlated with changes in kinematics and PROM. Understanding the mechanisms by which tSCS may affect gait for children with CP is critical to optimize and inform the use of tSCS for clinical care.
