GeekWire, a national technology news resource, has featured Dr. Steele and Dr. Schwartz‘s Walk-DMC in a special series focused on community issues and innovative solutions to societal challenges. Lisa Stiffler reports on the analysis that is used to create Walk-DMC, an assessment tool that uses routinely collected electromyography (EMG) data to identify which kids are the strongest candidates for surgery — and to help develop alternative treatments for children needing a different solution.

“It’s a very complex problem,” said Steele, who is a co-author of a paper explaining the Walk DMC metric published this month in the journal Developmental Medicine & Child Neurology. “You can have two individuals who are walking visually nearly identically,” she said, “but how they’re controlling that motion can be very different.”

Techbridge – Elementary Girls Visit Lab

Techbridge is a program that inspires girls to discover a passion for technology, science and engineering. Through hands-on learning, they empower the next generation of innovators and leaders.

We had two groups of young women join us in our lab to talk about mechanical engineering and how we use engineering principles to help individuals with movement impairments. To demonstrate the human body’s ability to control devices, the girls took turns moving a robot gripper using the electrical signals read from their own arm muscles (read more about this neat application here).Elementary school girls surround a large demo-filled table during a visit to the Ability and Innovation Lab.Three look on as a young girl controls a robotic gripper using electrical signals generated neurologically from her brain to her bicep brachii arm muscle.

Featured in UWToday: Michael Schwartz and Kat Steele have developed a quantitative assessment of motor control in children with cerebral palsy

Our lab’s director, Dr. Kat Steele, and Dr. Michael Schwartz, from Gillette Children’s Specialty Healthcare, have developed a quantitative assessment of motor control in children with cerebral palsy called Walk-DMC, which could be used to help determine whether or not patients would benefit from aggressive, invasive surgeries to assist in walking and motion. Jennifer Langston reports on the new technique within UWToday. An exert from the article is posted below, but for the full article, read HERE.

“Only about 50 percent of children have significant improvement in their movement after these highly invasive surgeries,” said Kat Steele, a UW assistant professor of mechanical engineering. “Our motivation has really been to figure out how we can push up these success rates.”

Engineering Discovery Days

Our lab had a great time sharing our research at the College of Engineering Discovery Days. Our booth was entitled, “The Ultimate Machine” because we think of the human body as a complex system with our brain as a controller/computer and our muscles as our motors. Elementary and middle school students used their neural pathway, from brain to muscle, to control a robot gripper by either relaxing or activating their muscle.  A student activates his muscle to hold a golf ball with a robot gripper Our lab director, Kat Steele, explains why ankle foot orthoses are used and what we are doing to optimize the device. Another student tries her luck at holding a golf ball with a robot hand. The record hold time was 170 seconds. A group of students cheer on their peer as he activates his muscle to hold a golf ball with a robot gripper Elementary and middle school aged students try on 3D printed prosthetic devices

Kat Steele receives Junior Faculty Award from the College of Engineering

Members of the DO-IT A-team visit the Steele Lab and learn about engineering.Kat Steele won the Junior Faculty Award for her novel and innovative research in biomechanics, high level of commitment to students and teaching, enhancement of participation of under-represented groups, and a direct contribution to the quality of the life of kids with cerebral palsy. Congratulations, Kat! The Mechanical Engineering department was awarded three of the total eight awards for the College of Engineering. Congratulations to Mark Jankauski for winning the Student Teaching Award  and Eric Seibel who won the Faculty Research Award.
