Journal Article in Assistive Technology

Access to powered mobility can support play and development for toddlers with disabilities. Using powered mobility in a standing posture has been theorized to support development of muscle coordination, balance, head and trunk stability, and transition to ambulation.

3 graphs showing the number of joystick activations, longest joystick activation, and loading through the base over the 13% bodyweight threshold in each play session for each participant for both SIT (left, open) and STAND (right, filled).

Aim: The purpose of this study was to quantify and characterize joystick control, bodyweight support, and muscle activity while using the Permobil Explorer Mini in seated and supported standing postures.

Methods: Nine children with mobility disabilities participated in four visits where they completed two, 15–20 minute play sessions, one in each posture, with a break between.

Results: We found that all toddlers engaged with the joystick in both postures, with individual differences in favored directions and control patterns. Participants had similar loading through their feet in both postures, but had slightly higher muscle activity in standing, especially while driving.

Interpretation: These results demonstrate that young children with disabilities quickly engage with joystick-based powered mobility in seated and standing postures, with important individual differences that can inform future design of devices and interventions to support play and development.

Riley Bernas presents at the CNT 2024 Summer Undergraduate Research Symposium

Katie Landwehr News, Presentation , , , ,

This summer, the Steele Lab hosted undergraduate researcher, Riley Bernas, from the University of Connecticut. Riley was mentored by Mia Hoffman, Heather Feldner, and Kat Steele.

She finished up her 10-week summer Research Experience for Undergraduate (REU) by presenting at the 2024 Summer Undergraduate Research Symposium with the Center for Neurotechnology (CNT).

Riley gave a podium and poster presentation titled “Quantifying low-cost switch access play-kit usage in clinical settings: A first glance.“

Way to go, Riley!

Switch Kit Workshop at Boyer Clinic

Katie Landwehr News, Outreach , , , , ,

Steele Lab members, Mia Hoffman, Riley Bernas, and Katie Landwehr led a “Switch Kit” Workshop at Boyer Clinic in Seattle, WA.

The workshop aimed to teach Pediatric Physical Therapists, Occupational Therapists, Speech-Language Pathologists, and Educators how to use a new system we have designed with local families and clinicians for inclusive play options in early intervention. The Boyer Team also got to try a variety of adaptive switches Mia, Kate, and Alisha made.

Stay tuned for more on this project!

Spring 2024 CREATE Research Showcase

Katie Landwehr HuskyADAPT, News, Presentation , , ,

The Center for Research and Education on Accessible Technology and Experiences (CREATE) hosted a Research Showcase and Community Day 2024 on May 20th. These events brought industry and community partners — leaders working and living in the disability and accessibility space — together with faculty and student researchers. Co-sponsored by HuskyADAPT. CREATE’s mission is to make technology accessible and to make the world accessible through technology.

Steele Lab members, Alexandra (Sasha), Mia, Kate, and Alisha,  presented posters at the CREATE Research Showcase to highlight design, development & research of technology to support individuals with disabilities.

Mia, Kate, and Alisha presented a poster on “The Switch Kit: bridging the gap in therapeutic toys for children with medical complexities“. This research involved the creation and evaluation of a therapeutic toy named the “Switch Kit,” designed for young children with medical complexities. The kit allows family members and clinicians to customize switches tailored to the unique needs of each child.

Alexandra presented a poster on “Camera-Based Interface for Hand Function Assessment”. Currently, hand function assessment (e.g., joint range of motion) in a clinical setting is done with low-resolution tools and oftentimes in a subjective manner that is time-consuming. With a camera-based interface, we wanted to improve the speed of collecting information about patient’s hand function, improve repeatability and objectivity, and enhance result presentation for both patients and clinicians.
