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.

Spring 2024 CREATE Research Showcase

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.

Introducing Dr. Charlotte DeVol Caskey!

Congratulations to Dr. Charlotte DeVol Caskey on earning her Doctorate in Mechanical Engineering! Dr. Caskey’s PhD thesis dissertation was titled Effects of Spinal Stimulation on Neuromechanics of Gait for Children with Cerebral Palsy. Congratulations and best of luck as you move forward as a Postdoc in the Human Neuromechanics Laboratory at the University of Florida in Gainesville!

UW CREATE Presents at the UWFB Meeting Spring 2024

The Center for Research and Education on Accessible Technology and Experiences (CREATE) presented at the University of Washington Foundation Board Meeting Spring 2024.

Kat Steele, Associate Director of CREATE introduced the impact of the center over its first 5 years and trainees, including former CREATE postdoc Kim Ingraham, present our research on the impact of access to early powered mobility at the board meeting. Check out the presentation (starting at 59 minutes, link to video on YouTube HERE ).

During the Cocktail Hour Showcase, Heather Feldner and Mia Hoffman also shared their work with HuskyADAPT and the development of accessible design and play technology.

As highlighted through these presentations, CREATE’s mission is to make technology accessible and to make the world accessible through technology.

EC Kuska, KM Steele (2024) “Does crouch alter the effects of neuromuscular impairments on gait? A simulation study”

Journal Article in Journal of Biomechanics

Cerebral palsy (CP) is a neurologic injury that impacts control of movement. Individuals with CP also often develop secondary impairments like weakness and contracture. Both altered motor control and secondary impairments influence how an individual walks after neurologic injury. However, understanding the complex interactions between and relative effects of these impairments makes analyzing and improving walking capacity in CP challenging.

A sagittal-plane musculoskeletal model and neuromuscular simulation framework that tracked average nondisabled (ND) kinematics and moderate and severe crouch gait. The model contains nine degrees-of-freedom (pelvic tilt and translation, and right and left hip, knee, and ankle flexion) actuated by eight Hill-type musculotendinous units per leg. The objective function minimized deviations from tracked kinematics and the sum of muscle activations squared (a2). We perturbed each gait simulation with multi-modal neuromuscular impairments—altered control, weakness, and contracture—of varying severities. Altered control was simulated by reducing the number of fixed synergies controlling each leg, and weakness and contracture were simulated by reducing a muscle’s maximum isometric force ( ) and tendon slack length ( ), respectively. A Bayesian Additive Regression Trees (BART) model then predicted resultant a2 from the simulated neuromuscular impairments for crouch and ND gait to evaluate the relative effects of each simulated neuromuscular impairment on the muscle activations required to maintain each gait pattern.Aim: The purpose of this study was to investigate the interactions between neuromuscular impairments and gait in CP.

Methods: We used a sagittal-plane musculoskeletal model and neuromuscular control framework to simulate crouch and nondisabled gait. We perturbed each simulation by varying the number of synergies controlling each leg (altered control), and imposed weakness and contracture. A Bayesian Additive Regression Trees (BART) model was also used to parse the relative effects of each impairment on the muscle activations required for each gait pattern.

Results: By using these simulations to evaluate gait-pattern specific effects of neuromuscular impairments, we identified some advantages of crouch gait. For example, crouch tolerated 13 % and 22 % more plantarflexor weakness than nondisabled gait without and with altered control, respectively. Furthermore, BART demonstrated that plantarflexor weakness had twice the effect on total muscle activity required during nondisabled gait than crouch gait. However, crouch gait was also disadvantageous in the presence of vasti weakness: crouch gait increased the effects of vasti weakness on gait without and with altered control.

Interpretation: These simulations highlight gait-pattern specific effects and interactions between neuromuscular impairments. Utilizing computational techniques to understand these effects can elicit advantages of gait deviations, providing insight into why individuals may select their gait pattern and possible interventions to improve energetics.
