NL Zaino, KA Ingraham, ME Hoffman, HA Feldner, KM Steele (2024) “Quantifying toddler exploration in different postures with powered mobility”

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.

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.

Ally Clarke & Madeleine McCreary join the Steele Lab

We are excited to welcome two new PhD students, Ally Clarke and Madeleine McCreary, to the Steele Lab this fall.

Ally joins us after finishing her B.S. degree in biomedical engineering from Bucknell University. Ally is interested in studying neuromuscular biomechanics to increase accessibility for people with limited mobility. She is especially excited about the combination of experimental and computational methods to gain a comprehensive understanding of the neuromuscular system. Outside of the lab, Ally enjoys Running, hiking, crocheting, baking, and reading.

Madeleine joins us after finishing her B.S. degree in biomedical engineering, minor in electrical engineering from the University of Florida. Madeleine is interested in utilizing neuromodulation as a physical therapy tool for children with cerebral palsy. She is excited to learn how neuromodulation affects the central nervous system with repeated use and the impact it has on motor control. Outside of the lab, Madeleine enjoys fencing, cooking, tennis, hiking, and reading.

Welcome to the University of Washington, Ally & Madeleine!

Riley Bernas presents at the CNT 2024 Summer Undergraduate Research Symposium

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!

ASB 2024 Recap

Steele Lab members, Charlotte Caskey, Victoria (Tori) Landrum, and Megan Ebers, attended the American Society of Biomechanics Annual Meeting (ASB) in Madison, WI from August 5-8, 2024.

Charlotte gave a poster presentation on the “Effect of spinal stimulation and interval treadmill training on gait mechanics in children with cerebral palsy”

Tori also gave a poster presentation on the “Impact of a Resistive Exoskeleton on Fatigue in Children with Cerebral Palsy”

Megan co-hosted a Symposia Session titled, “Can machine learning reveal the next generation of neural and biomechanical processes governing human movement?” with Steele Lab Alumni, Michael Rosenberg. In Megan’s talk, “A machine learning approach to quantify individual gait responses to ankle exoskeletons,” she discussed how neural network-based discrepancy modeling can be used to isolate the dynamics governing changes in gait with ankle exoskeletons.

KM Steele (2023) After Universal Design Book Chapter – “Shaping Inclusive and Equitable Makerspaces”

Book Chapter in After Universal Design: The Disability Design Revolution, Edited by Elizabeth Guffey

Makerspaces are often used to help build new assistive technology and increase accessibility; however, many of these spaces and tools remain inaccessible. We need to make sure disabled people can access these spaces and create the products and designs that they actually want.
– DO-IT Scholar

Dr. Steele was asked to contribute a case study focused on her work with AccessEngineering into Shaping Inclusive and Equitable Makerspaces.

Description: How might we develop products made with and by disabled users rather than for them? Could we change living and working spaces to make them accessible rather than designing products that “fix” disabilities? How can we grow our capabilities to make designs more “bespoke” to each individual? After Universal Design brings together scholars, practitioners, and disabled users and makers to consider these questions and to argue for the necessity of a new user-centered design.

As many YouTube videos demonstrate, disabled designers are not only fulfilling the grand promises of DIY design but are also questioning what constitutes meaningful design itself. By forcing a rethink of the top-down professionalized practice of Universal Design, which has dominated thinking and practice around design for disability for decades, this book models what inclusive design and social justice can look like as activism, academic research, and everyday life practices today.

With chapters, case studies, and interviews exploring questions of design and personal agency, hardware and spaces, the experiences of prosthetics’ users, conventional hearing aid devices designed to suit personal style, and ways of facilitating pain self-reporting, these essays expand our understanding of what counts as design by offering alternative narratives about creativity and making. Using critical perspectives on disability, race, and gender, this book allow us to understand how design often works in the real world and challenges us to rethink ideas of “inclusion” in design.
