ESMAC 2019: Award Finalists

Congratulations to Nicole Zaino and our colleague Mike Schwartz at Gillette Children’s Specialty Healthcare for both being nominated as finalists for the Best Presentation Award at the upcoming ESMAC Conference in Amsterdam. Their abstracts are among the top 16 submissions to the conference and the final award will be determined based upon their presentations.

Nicole will be presenting her research:

Spasticity reduction in children with cerebral palsy is not associated with reduced energy during walking 

Selective dorsal rhizotomy reduces spasticity, but does it also reduce energy consumption during walking? In an analysis of over 300 children with cerebral palsy, Nicole demonstrated that although rhiztomy does reduce spasticity, it does not reduce energy consumption. These results provide further evidence that spasticity is not a main contributor to elevated energy among people with cerebral palsy. You can also learn more about this study from our recent submitted manuscript, available on bioRxiv.

Mike will be presenting his research:

The effects of walking speed and age on energy consumption in children with cerebral palsy and their typically developing peers

We know that walking energy is high among people with cerebral palsy, and that energy varies with speed and age. Using retrospective data of over 300 kids with cerebral palsy and 150 typically-developing peers, Mike used a statistical model to evaluate these speed and age effects. He found that energy decreases until 8-10 years of age for kids with CP, while it remains stable beyond age 5 for typically-developing peers. Kids with CP also have a greater elevation in energy with greater walking speeds. These results are important to help quantify and understand impacts of interventions, like surgery or assistive devices, which are often done during this time period when kids are still growing and developing.

They will both be presenting in the Optimizing Energy Cost session from 11:40-12:30 on Thursday, September 26th.

Best of luck to Nicole & Mike!

HuskyADAPT toy hackathon event with Microsoft

Alyssa Spomer along with HuskyADAPT (Accessible Design & Play Technology) hosted the first-ever adapted toy Hackathon with Microsoft. The event combined design and toy adaptation, as teams of HuskyADAPT students and Microsoft employees worked together to adapt toys and develop new designs for adapted toy switches and switch mounts.

Groups of people sitting around wooden tables with parts strewn about, many of them wearing greens shirts, with a younger gentleman writing on a white board with another gentleman smiling at the table and examining what he is writing  A woman wearing a orange jackets and black shirt and a man wearing a green shirt smiling while holding a toy in front of a workshop

Over 25 Microsoft employees joined 20 students, including the Steele Lab’s own Alyssa Spomer, Nicole Zaino, Charlotte Caskey, and Elijah Kuska, in the CoMotion MakerSpace for this community-focused and adaptive driven workshop.

During the day-long hackathon, over 20 toys were adapted to incorporate a new switch mechanism to facilitate play and several new inexpensive switches, toy-type converters, and switch mounting systems were designed and prototyped.  Thank you to the Microsoft employees, for their willingness and commitment to assist those in need, the CoMotion MakerSpace volunteers, for allowing us to use their space, and our HuskyADAPT team and lab members, for their dedication to outreach events.

Research Experience Undergraduates Present at CNT

This summer the Steele Lab had the pleasure of hosting three undergraduate researchers – Robin Yan from University of Washington, Ava Lakmazaheri from Olin College of Engineering, and Katherine Chamblin from University of Washington.

After a competitive selection process, students are offered a 10-week internship here at the University to work directly with a research lab on campus. One of the program’s final deliverables is a presentation of their work, both in podium and poster format, to members of the local and scientific community. Congratulations to Robin, Ava, and Katherine for their successful time here in the lab, and for giving polished presentations.

ISB 2019 Recap

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.

US Patent Office Visit

Patent examiners spend their days critically evaluating the latest innovations, to determine if they are useful, novel, and non-obvious. When one of our students asked them what daily life is like as a patent examiner they responded, we basically write a 10-15 page report every 2-3 days.

Thankfully the patent office lets them escape from behind their computers a few times a year to meet with companies, research labs, and other entities. These visits help them see what is new and exciting in their specialty area.

We were lucky enough to host one of these teams this past week in the AMP Lab. Tim Stanis, a primary examiner from Art Unit 3786 that specializes in exoskeletons, orthoses, passive motion rehabilitation devices, and biomechanical technology led the visit. He was joined by nine other examiners.

Our lab demoed our latest creations in orthoses, biofeedback systems, and smartphone sensing. Patrick Aubin from the VA Hospital, Murray Maitland from Rehab Medicine, Chet Moritz from Electrical Engineering, and Tapo Bhattacharjee also shared their latest work.

We ended the session with a Q&A Panel for summer students to learn about career opportunities as a patent examiner and advice for new innovators. Most of the examiners had an undergraduate or master’s degree in engineering. They emphasized that working for the patent office is a great, flexible career path. As a patent examiner they are able to work remotely, have flexible hours, and enjoy other benefits such as having law school paid for.

Students listen attentively to the Q&A Panel. Some look bored, some look amused, and one is even taking notes, or maybe doodling!

For new innovators, they emphasized the importance of understanding the patent landscape. They recommended using Google Patents! Patents can seem intimidating. They recommended starting with the pictures and focusing on the claims. They also emphasized the importance of having a team. Translating technology requires team members with technical, business, and clinical backgrounds.

For our part, we were excited to meet real, live patent examiners. We appreciated seeing their faces and enjoyed sharing our work with them.
