  • Introducing Xinru Chen, BS

    Xinru Chen, BS, is conducting her BME graduate research at NUPOC under the supervision of Steven A. Gard, PhD.Xinru Chen, BS, has joined NUPOC to conduct research in partial fulfillment of her Master’s degree in Biomedical Engineering (BME). Steven A. Gard, PhD, will guide Ms. Chen in her research on optimization of prosthetic foot and ankle stiffness to approximate able-bodied gait. Using mechanical testing, Ms. Chen’s project proposes systematic changes to foot-ankle stiffness to determine an optimum stiffness for biomimetic gait. She expects to complete her thesis work by May 2017. (Learn more about this Department of Veterans Affairs-funded research project: Optimization of Prosthetic Foot and Ankle Stiffness for Standing and Walking.)

    Ms. Chen graduated with a BS in Molecular Biomedical Sciences with first class honors and a minor in Information Technology (Hong Kong University of Science and Technology, 2012). She matriculated to Northwestern University for her graduate work, initially in Interdepartmental Neuroscience. She transferred to BME where she foresees that work in prosthetics can be more immediately applied to produce positive, tangible outcomes. She said, “I planned a graduate career in molecular neuroscience looking at individual cells. But I wanted to move up to a broader system level. I recognized that I wanted my work to be more clinically relevant to real people, not mice. That’s why I shifted my emphasis to BME and prosthetics research.”

    In microbiology and neuroscience, Ms. Chen has participated in a range of mentored and team research projects that include: analysis of synaptic organization; programing custom MATLAB® scripts to control and analyze electrophysiology experiments; optimizing a biochemical assay for quantification of total Amyloid β-derived synaptogenesis and PTEN-regulated axonal growth of retinal ganglion cells; and examination of the expression pattern and function of a gene expected to have a developmental role in C. Elegans. She contributed to the Silver Medal team in the International Genetically Engineered Machine Competition (iGEM, 2009), and has presented podium talks and research posters. She enjoys teaching and has volunteered as an instructor for hands-on science sessions and conversational Mandarin. 

    Her passion for science and engineering may have been natural outgrowths of exposure to her parents’ careers in computer science, civil engineering, physics and biology. Interested in theories and reasons, Ms. Chen frequently visited her mother’s office where she observed her mother’s civil engineering projects and appreciated their impact on people and the society.

    Ms. Chen enjoyed being an exchange student at the University of Wisconsin-Madison and said, “The winter weather was interesting.” In her free time, she enjoys kayaking, paddle boarding, and biking with her friends. Currently, she is considering various options and has not yet decided on her course after completing her Master’s degree.

  • Donaldson Exhibit Opens at NUPOC

    NUPOC features Donaldson exhibit

    At NUPOC science, technology, and art intersect. In recognition of the artistry that is vital to prosthetics and orthotics, NUPOC is delighted to announce the installation and exhibition of five abstract acrylic paintings by Jane Donaldson. Ms. Donaldson trained with artists Tim James and Katherine Hilden. She is a member of the Evanston Art Center and lives in Wilmette, IL.

    Artists and Certified Prosthetist-Orthotists (CPO) cultivate similar skills. A maxim holds that a good prosthetist-orthotist needs the triumvirate of “head, heart, and hands”. Superior cognitive ability, compassion, and hand skills enable CPOs to serve their patients well. As scientists and clinicians, CPOs are rigorously trained in human anatomy, biomechanics, behavioral sciences, professional issues, practice management, and independent research. To fabricate functional, comfortable, intimately fitting prostheses and orthoses, CPOs also employ a creative artistry that bridges science and technology.

    NUPOC appreciates Jane Donaldson for making this exhibit possible.

  • Improving Clinical Practice and QOL for Lower Limb Amputees

    Allen Heinemann, PhD    Stefania Fatone, PhD, BPO(Hons)

    Research conducted by Allen Heinemann, PhD, and Stefania Fatone, PhD, BPO(Hons), Enhancing Quality of Prosthetic and Orthotic Services with Process and Outcome Information, is in the news as a professional publication and again as the focus of an interview. The study investigates whether external facilitation of activities can improve Quality of Life (QOL) for lower limb amputees. The interview, “External Facilitation Could Aid Clinics’ Quality Improvement Measures” (O&P News, Fall 2016) is based on a recently published article of the same title (Heinemann A, Ehrlich-Jones L, Connelly L, Semik P and Fatone S (2016) Enhancing Quality of Prosthetic Services with Process and Outcome Information. Prosthetics and Orthotics International 1-7. DOI: 10.1177/0309364616637957).

    At participating clinics, patients who were prescribed a new prosthesis or a socket replacement completed the Orthotics Prosthetics Users’ Survey (OPUS) three separate times. Clinical staff identified and developed an action plan for lower limb issues that could be addressed, improved, and measured during the course of a year, after which time clinic staff concluded their external facilitation and evaluated the quality improvement programs that they had incorporated into routine operations. Feedback from the prosthetics clinics indicated that “clinicians understood the importance of monitoring patient progress and found the combination of function, quality of life, and satisfaction with device and services to be unique and valuable information.”

    This reesearch was conducted as a development project of the Rehabilitation Engineering Research Center for Prosthetics and Orthotics (2008-2013), funded by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR).
