  • University of Salford Researchers Visit NUPOC, Discuss ESR Prostheses
    12/13/2016

    David Howard, PhD   James Gardiner, PhD 

    NUPOC welcomed David Howard, PhD, Professor of Biomedical Engineering, and James Gardiner, PhD, Postdoctoral Research Fellow, both from the University of Salford, Manchester, UK. Dr. Gardiner and Dr. Howard visited NUPOC at the invitation of Matthew Major, PhD, who completed his doctoral work at the University of Salford under the supervision of Professor Howard. NUPOC researchers discussed mutual research interests with Dr. Howard and Dr. Gardiner.

    Drs. Gardiner and Howard presented a talk that examined scientific evidence suggesting that passive Energy Storage and Return (ESR) lower limb prostheses do not significantly improve the metabolic cost of walking, partly due to the absence of adequate push-off. They also presented a simulation study they developed to establish the feasibility of using a miniature hydraulic variable displacement actuator (VDA) within a prosthesis. The proposed device would store the eccentric ankle work from heel strike to maximum dorsiflexion in a hydraulic accumulator and then return the stored energy to power push-off. Design optimization established the best parallel spring characteristic and gear ratio between ankle and VDA. In level walking, normal push-off can be achieved and, over each gait cycle, the energy stored in the accumulator would increase by 22% of what is required for normal push-off. Yet to be developed is a miniature, low-losses, lightweight VDA that is half the size of the currently available smallest commercial device.

    NUPOC appreciates Dr. Major for inviting the researchers from the University of Salford and hosting the research seminar.

  • Introducing Julia Quinlan, PhD
    12/06/2016

    Julia Quinlan, PhDJulia Zelenakova Quinlan, PhD, has joined NUPOC as a Postdoctoral Fellow sponsored by a NIDILRR Advanced Rehabilitation Research Training Grant (Principal Investigators, Steven A. Gard, PhD, and Zev Rymer, PhD). During the one year grant period, Dr. Quinlan will work on a Department of Defense funded research project, No Longer Smooth: Introducing Striations into Prosthetic Socket Construction to Improve Suspension, Rotation, Fit and Comfort, led by Principal Investigator Stefania Fatone, PhD, BPO(Hons). The project goals are to investigate the effect of different types of texturing on suspension, rotation, fit, and comfort, specifically to test if horizontal striations improve suspension; and if vertical striations help control transverse plane rotation for transtibial sockets.

    Dr. Quinlan will develop testing setups, fabricate required testing fixtures, and conduct experiments that will measure the coefficient of friction using sled and table friction; evaluate the tensile and static strength of sockets with different texturing patterns using a dumbbell specimen; and develop testing protocols for an INSTRON® material testing machine.

    Dr. Quinlan earned a doctorate in Bioengineering with a concentration in Biomechanics at the University of Illinois-Chicago (UIC); and a Master’s of Science in Biomedical Engineering with a concentration in Biomedical Engineering at The Technical University of Košice (TUKE), Slovakia. At TUKE, she was recognized with a Dean’s Award for Outstanding Graduate Student. Her doctoral dissertation addressed “Effect of Binge Alcohol Exposure on Intervertebral Disc Structure and Mechanical Properties in Adult Rats” and her Master’s thesis examined “Ambient Intelligence Tools Applied in Everyday Activities in the Home Environment”. Her work has contributed to 20 conference abstracts and presentations and she is a named author on 6 publications.

    In addition to her academic training, she also brings research experience in the Musculoskeletal Biomechanics Research Laboratory, Edward Hines Jr. Veterans Affairs Hospital, Hines, IL, where she conducted spine biomechanics and general orthopedics research. She has worked as a technology commercialization analyst and consultant at the UIC Office of Technology Management. During her doctoral training at UIC, she taught 6 years of classes in Senior Design I and II and Biomechanics.

    Her early interest in mathematics and science led her to apply and be immediately accepted into the highly competitive BME department at TUKE. Although education is state subsidized, acceptance to each stage of educational promotion is rigidly controlled by increasingly difficult entrance examinations. Dr. Quinlan reflected, “Typically, about 1,500 students will be accepted to begin a course of study, but ultimately only about 60 people will graduate. If a student fails a class, s/he has 2 years to pass it. Students who fail or drop out must re-apply through the examination system.”

    Born during communist rule in Czechoslovakia, after the dissolution of Czechoslovakia in 1993, Julia, her parents and younger brother lived in the independent and democratic Slovak Republic. To experience American culture firsthand and to hone her fluency in English, she spent 4 months in 2005 working for an exchange program in Yellowstone National Park where she developed strength and self-confidence by managing a series of life-changing personal and financial challenges. In 2006, prior to moving to the USA to pursue her doctorate, she spent a semester as a Socrates-Erasmus exchange student studying BME in Ghent, Belgium.

    Dr. Quinlan noted that although she had hoped to remain in Europe to better support her mother, “I must have been born with wandering boots. I’ve lived in Chicago for nearly 10 years and my husband is American, so my future is here in the USA.” Recently, she seldom has leisure time, but has played competitive intramural soccer, and is an accomplished gardener and seamstress. Dr. Quinlan said, “I enjoy attending theatrical and musical performances with my friends. I have attended the last eight seasons of the Chicago Lyric Opera”.

    Dr. Quinlan is passionately committed to research. She intends to pursue a career within a university setting where she can conduct research related to the biomechanics of the human musculoskeletal system, publish the results of her research, and share her knowledge by teaching students. We are delighted to welcome Dr. Quinlan and her multiple skills to NUPOC.
