EASI Webinar

Title slide from AccessEngineering webinar.AccessEngineering presented a webinar with Equal Access to Software and Information (EASI) on:

Incorporating universal design topics into postsecondary computer science and engineering courses

Speakers included Kat Steele from Mechanical Engineering, Maya Cakmak and Richard Ladner from Computer Science & Engineering, and Sheryl Burgstahler from UW’s DO-IT program. You can still watch the webinar and learn some techniques for integrating universal design and accessibility into your lectures, courses, or labs here.

 

Making Accessible Makerspaces

Maya Cakmak from computer science brainstorms the ideal wallet design.This week a team of our faculty and undergraduate students (3 research students from the Center for Sensorimotor Neural Engineering and 6 scholars from the UW DO-IT program for teens with disabilities) took on the challenge to help make makerspaces more accessible. 

Many engineering departments, libraries, and universities are launching new initiatives to create makerspaces, physical spaces where students, faculty, and the broader community can gather and share resources and knowledge, work on projects, network, and build. In creating these innovative spaces we should consider principles of universal design to ensure the spaces, tools, and community are accessible to as many individuals as possible.

As one of our participants told us, accessibility of makerspaces is especially important because:

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.

The students toured the UW’s CoMotion Makerspace before completing a prototyping challenge to design the ideal wallet. Students worked in teams of two and dove into our challenge which focused upon both teaching need-based, human-centered design while also giving students the chance to get messy, test out tools, and create. The groups came up with some great insights into how wallets could be improved and prototyped some creative designs. Through this activity we also learned about some of the challenges in the space, tools, and design activity:

  • Students loved the moveable tables and flexible workspace – this let everyone find a comfortable and inviting space to create.
  • Individuals with visual impairments also said they like the flexible workspace, but also highlighted that it was great that tools were in specific, fixed locations. These individuals emphasized that they build mental maps of a space and, although it is fine to have equipment on wheels, it helped knowing the tools, 3D-printer, laser cutter, etc wouldn’t change locations.
  • In the design activity, sketching to share ideas was challenging for some of the participants. Having a diverse set of prototyping tools like clay, cardboard, etc can help to quickly share ideas.

We’ll be taking the feedback from these students and integrating with feedback from faculty, staff, and other community members to help create guidelines and best practices for accessible makerspaces. Stay tuned!

WalkDMC decreased with GMFCS level among individuals with cerebral palsy.

Journal article accepted in Developmental Medicine & Child Neurology:

Kat Steele partnered with Mike Schwartz and Adam Rozumalski of Gillette Children’s Specialty Healthcare to complete one of the largest studies to date of individuals with cerebral palsy. They quantified how neuromuscular control is altered among individuals with cerebral palsy and how this altered control can contribute to impaired function.

WalkDMC decreased with GMFCS level among individuals with cerebral palsy.

Abstract: Individuals with cerebral palsy (CP) have impaired movement due to a brain injury near birth. Understanding how neuromuscular control is altered in CP can provide insight into pathological movement. We sought to determine if individuals with CP demonstrate reduced complexity of neuromuscular control during gait compared with unimpaired individuals and if changes in control are related to functional ability. Muscle synergies during gait were retrospectively analyzed for 633 individuals (age range 3.9–70y): 549 with CP (hemiplegia, n=122; diplegia, n=266; triplegia, n=73; quadriplegia, n=88) and 84 unimpaired individuals. Synergies were calculated using non-negative matrix factorization from surface electromyography collected during previous clinical gait analyses. Synergy complexity during gait was compared with diagnosis subtype, functional ability, and clinical examination measures. Fewer synergies were required to describe muscle activity during gait in individuals with CP compared with unimpaired individuals. Changes in synergies were related to functional impairment and clinical examination measures including selective motor control, strength, and spasticity. InterpretationIndividuals with CP use a simplified control strategy during gait compared with unimpaired individuals. These results were similar to synergies during walking among adult stroke survivors, suggesting similar neuromuscular control strategies between these clinical populations. PDF

Also, make sure you look at the commentary from Diane Damiano. She provides perspective about the utility of synergies for evaluating neuromuscular control in children with cerebral palsy and future challenges.
