Five members of our lab – Kat, Michael, Alyssa, Megan, & Nicole – attended ISB 2019 in Calgary, Canada. The International Society of Biomechanics promotes and supports international contacts amongst scientists, the dissemination of knowledge, and the activities of national organizations in the field of biomechanics.

Our work at the conference included:

Kat Steele: ISB presentation on in-clinic EMG monitoring for muscle activity and movement in acute care in the initial days after stroke.
Michael Rosenberg: ISB poster showcasing how individuals’ kinematics and muscle activity change in response to ankle exoskeleton stiffness during acceleration from standing. ISB presentation on open-loop modeling of response to ankle exoskeleton torque during walking.
Alyssa Spomer: ISB poster highlighting how motor control is impacted when typically developing individuals emulate cerebral palsy gait patterns. ISB poster on understanding how individuals can alter motor control expression using visual biofeedback.
Megan Auger: ISB presentation on how muscle coordination strategies in typically developing children and children with cerebral palsy are not accurately captured using standard musculoskeletal modeling optimization algorithms in computer simulation.
Nicole Zaino: ISB presentation on spasticity reduction via rhizotomy in children with cerebral palsy and how there was no significant difference in the change in energy consumption when compared to a control group of children with cerebral palsy who had no rhizotomy.

TGCS 2019

Additionally, two members of our lab – Michael & Megan – attended TGCS 2019 in Canmore, Canada prior to ISB 2019. The Technical Group on Computer Simulation (TGCS) is a scientific and technical meeting for investigators and students in all areas of computer simulation in biomechanics. This group was a highly-focused subset of the ISB community, primarily focusing on forward simulation of unimpaired and pathological gait patterns, but also touching on multi-scale simulation, diving, cycling, and wheelchair use.

RehabWeek 2019 Recap

Five members of our lab – Brandon, Christina, Nick, Michael, & Kat – attended RehabWeek 2019 in Toronto, Canada. This is a unique mega-conference where multiple conferences (ICORR, ACRM, ISPO, RESNA, etc) are hosted at the same time in the same location. Everyone attended common keynotes, poster sessions, and meals. In the morning and afternoon, each conference had their own scientific sessions.

While it was a bit overwhelming to figure out which sessions to attend, it was a great way to get a more diverse audience to provide feedback on your work. For future conferences, I would recommend that students just pick one conference (e.g., ICORR or RESNA) to attend and not bounce between sessions. This lets you more fully engage with a community, have long discussions, and identify common threads across presentations.

Our work at the conference included:

  • Michael Rosenberg: ISPO presented on how muscle coordination differs when you start to walk compared to steady-state walking. Synergies differ during the first step, but quickly converge to steady-state patterns and there was minimal effect of different AFO stiffnesses.
  • Christina Papazian: INERS poster demonstrating correlations between FIM scores and muscle activity in acute stroke care.
  • Brandon Nguyen: ISPO poster on the accuracy and repeatability of using a smartphone to monitor gait for AFO tuning – ISPO Best Student Poster Award
  • Nick Baicoianu: Developer’s Showcase for HuskySTEPS
  • Kat Steele: ISPO poster on synergy-based control of predictive simulations of walking.

I also served on the IEEE Women in Engineering panel at lunch on Thursday, which focused on new frontiers in technology that could increase accessibility and inclusion. A lot of the discussion focused on the potential of machine learning, wearable technology, and autonomous vehicles.

You can view our notes and take-aways from the conference in these slides.

We also got to visit with Naser Mehrabi, a former post-doc in the lab, who now works for General Motors. We took the train just north of downtown to visit with him, his wife, and their 9-week-old son. Not only did we get to enjoy some delicious Iranian food, but we also got to get lots of simulation questions answered.

The next RehabWeek will be 2021 in Rotterdam, Netherlands.

Congratulations to Brianna Goodwin! She placed third in the Masters Student Paper Competition at the 2019 Summer Biomechanics, Bioengineering, & Biotransport Conference. Brianna presented her MS research using accelerometers to track arm movement for kids with cerebral palsy who were receiving constraint induced movement therapy at Seattle Children’s Hospital.

Brianna completed her MS in June 2018. She is currently working at the Mayo Clinic in Minnesota. Congrats Brianna!

Congrats to Brandon Nguyen who was awarded the Best Student Poster award by the International Society of Prosthetics & Orthotics Canada at RehabWeek in Toronto this past week! Brandon presented his work, “Accuracy and repeatability of using smartphone sensors for orthotic tuning.”

Check out his abstract and poster.

This work, in collaboration with Nick Baicoianu and Darrin Howell, examined the accuracy of measuring shank-to-vertical angle during walking with a smartphone compared to traditional motion capture systems. Shank-to-vertical angle is a measure used by orthotists and therapists for AFO tuning and gait training. The short story – placing the smartphone on the front of the shank can measure shank-vertical-angle with errors less than two degrees compared to traditional motion capture systems, with high intra-rater and inter-rater repeatability across days.

Brandon also recently finished his Doctorate of Physical Therapy (DPT) degree at the University of Washington – making him one of the rare engineer-therapists. In recognition of his efforts to combine academic scholarship with social awareness and concern, he was awarded the 2019 UW Graduate Medal.

Congratulations Brandon! We are so excited to see what you do next.

IdeaGen: Inclusive Design

Dr. Steele AccessEngineering, HuskyADAPT, Media, News, Presentation , , , ,

Dr. Kat Steele and lab alumni, Dr. Heather Feldner, were on the The Accessible Technologies & Inclusive Design Panel at the IdeaGen Global Innovation Summit hosted by Micrsofot on June 7, 2019. Scott Saponas served as the moderator, asking tough questions about how to encourage and expand inclusive design. A large portion of the summit celebrated the increasing inclusion of women in tech and entrepreneurial fields, while also highlighting the remaining barriers and challenges. We hope our panel also sparked reflection on ability as an important dimension of diversity that has important implications for the design and engineering of inclusive products, environments, and experiences.

The panel also included Dr. Jacob Wobbrock from UW and Oscar Murillo from Microsoft. This was another reminder of the powerhouse of accessibility researchers at UW and in the Seattle-area. An artist was capturing the summit through illustration – the whole day (it looked amazing and exhausting):

One of the challenging questions Scott asked was our favorite examples of successful inclusive design. I still find it disappointing that this is a challenging question. We have our classic examples – curb cuts, closed captioning, power toothbrushes, Oxo products – that have made life easier for many, but were originally conceptualized through the inclusion of individuals with diverse abilities.

There should be many more examples of success. This should be an easy question where we can quickly call to mind all of the outstanding examples in the world that celebrate the inclusion of individuals with diverse abilities in the design process and make our daily life more inclusive.

What are your favorite examples of inclusive design?

What technologies make you excited for a more inclusive world?
