Abstract:

The purpose of makerspaces is to increase access to “making” among the general community. Because of this social justice orientation, it is important to consider how welcoming and accessible makerspaces are to individuals with diverse abilities, including individuals with disabilities. This design brief examines a three-step process used to make a university-based makerspace more accessible and welcoming to
individuals with disabilities including a tour, design activity, and brainstorming session. The process helped identify simple changes that were made to the makerspace, as well as increasing student, faculty, and community access. Using a similar process, other makerspaces could improve the accessibility of their spaces, procedures, and tools.

Makerspaces provide the general community with a space to brainstorm, prototype, and create. Considering this, it is especially important to create a welcoming environment for individuals with diverse abilities, including individuals with disabilities.

Brianna Goodwin and Ben Shuman each selected as travel award winners

Keshia Abstract, Awards, MotorControl, News, Projects, Publications, UbiquitousRehabilitation

Congratulations to Brianna and Ben on being selected as two of the 23 awarded out of 272 applicants.

The De Luca Foundation informed Brianna that she had been selected as a winner of a 2018 Student Travel Award for funding to travel to the American Society of Biomechanics this summer. Her research focuses on “Wearable Technology to Monitor Hand Movement During Constraint-Induced Movement Therapy”.

Likewise, the foundation named Ben 1 of 8 student recipients of the travel award that will help fund his travels to Dublin for the World Congress of Biomechanics. His winning research topic was that “Pre-treatment synergy activations are associated with post-treatment gait in cerebral palsy”.

 

Claire Mitchell Presents Her Senior Capstone in BioE

Congratulations, Claire, on finishing your undergraduate capstone and for providing a fantastic culminating presentation!

For her senior capstone, Claire was challenged with creating a web-based application clinicians could use to compute and translate muscle synergies into the clinic. Her mentors and fellow collaborators were Ben Shuman, Nick Baicoianu, and Dr. Kat Steele. In June, Claire will head to Boston, MA to begin her position at Delsys.

Claire Mitchell stands by a projection of her presentation in an auditorium. She is providing a live demonstration of her web based application.

Claire Mitchell, Karley Benoff, and Makoto Eyre present at the Mary Gates Research Symposium

On May 18th, Claire Mitchell, Karley Benoff, and Makoto Eyre presented their research at the Mary Gates Undergraduate Research Symposium. These three students worked on year-long projects and showcased their hard work during a campus-wide poster session.

Claire’s research focused on creating a website and server framework for clinicians and researchers across the country to use for calculating muscle synergies for motor control analysis. Muscle synergies are an incredibly complex and computationally expensive analysis of electromyography data but provide quantification of motor control and assist in therapy prescription for movement disorders.

Claire Mitchell, and undergraduate student in the Steele Lab, stands in front of her poster at Mary Gates Hall during the undergraduate research symposium. Claire is wearing a white and blue floral blouse. She is in the middle of describing her research project to four community members who have taken an interest in her research.

Makoto Eyre and Karley Benoff stand nearly back to back in front of their poster at Mary Gates Hall during the undergraduate research symposium. Makoto is facing to the left of the poster, and is wearing glasses, a white button up shirt and black slacks while conversing with members of the community outside of the images capture. Karley Benoff has shoulder length brown and blonde hair and is wearing a pink blouse while helping to fit a member of the community with her 3D-printed device at the elbow. Karley and the female community member are making sure the device's elbow joint is aligning well with the community member's elbow.

 

 

 

 

 

 

Karley and Mako’s research focused on designing and testing a 3D-printed elbow-driven orthosis for individuals with limited hand function. They drew inspiration from upper-extremity prosthetic devices and evaluated a voluntary close and voluntary open mechanism to assist an individual’s dominant limb.

Great work Karley, Mako, and Claire!

The interior courtyard of Mary Gates Hall has interior windows and a combination of new and old architectural elements. This is the location where hundreds of undergraduate presenters and community members discuss research accomplishments and next steps.

Sample sEMG signal from one subject’s FCU for (left) MVIC; (middle) dynamic and (right) functional tests indicate that there were no significant differences between the Delsys (lighter grey) and ESS electrodes (darker grey) based on raw sEMG amplitude, linear envelope amplitude, or power spectral density.

Journal article in Sensors:

In collaboration with University of Texas – Austin, we evaluated a new flexible, gold-based epidermal electrode for sensing muscle activity.

Sample sEMG signal from one subject’s FCU for (left) MVIC; (middle) dynamic and (right) functional tests indicate that there were no significant differences between the Delsys (lighter grey) and ESS electrodes (darker grey) based on raw sEMG amplitude, linear envelope amplitude, or power spectral density.Background: Commercially available electrodes can only provide quality surface electromyography (sEMG) measurements for a limited duration due to user discomfort and signal degradation, but in many applications, collecting sEMG data for a full day or longer is desirable to enhance clinical care. Few studies for long-term sEMG have assessed signal quality of electrodes using clinically relevant tests. The goal of this research was to evaluate flexible, gold-based epidermal sensor system (ESS) electrodes for long-term sEMG recordings.

Methods: We collected sEMG and impedance data from eight subjects from ESS and standard clinical electrodes on upper extremity muscles during maximum voluntary isometric contraction tests, dynamic range of motion tests, the Jebsen Taylor Hand Function Test, and the Box & Block Test. Four additional subjects were recruited to test the stability of ESS signals over four days.

Results: Signals from the ESS and traditional electrodes were strongly correlated across tasks. Measures of signal quality, such as signal-to-noise ratio and signal-to-motion ratio, were also similar for both electrodes.

Conclusions: Over the four-day trial, no significant decrease in signal quality was observed in the ESS electrodes, suggesting that thin, flexible electrodes may provide a robust tool that does not inhibit movement or irritate the skin for long-term measurements of muscle activity in rehabilitation and other applications.
