    NSLC Biotechnology Group, August 8, 2016

     NSLC Biotechnology Group visited NUPOC on August 9, 2016.

    NSLC students closely examined prosthetic devicesAs part of NUPOC’s commitment to educating and engaging youth in the STEM fields of Science, Technology, Engineering, and Mathematics, the Center presented “High Tech, Low Tech, the Right Tech” to nearly 100 members of the 2016 National Student Leadership Conference (NSLC) Biotechnology Group. Following an orientation tour of NUPOC facilities conducted by Steven A. Gard, PhD, Pranitha Gottipati, PhD, and Lilly Tran, MS, NUPOC personnel introduced NSLC students to areas of research and clinical practice related to rehabilitation engineering, biomechanics, and Prosthetics and Orthotics (P&O).

    MDr. Major presented the fundamentals of gait biomechanics and biometrics.atthew Major, PhD, presented “Understanding the Biomechanics of Human Gait and Its Application to Prosthetic & Orthotic Devices”. Emphasizing the importance of using valid and reliable biometrics to measure human motion, Dr. Major introduced comparative biometrics, including the high tech system for human motion capture to measure dynamic forces and joint angles of motion and the simple, but reliable goniometer to measure joint range of motion. Dr. Major also compared the digital PEDAR and the analog Harris Beath Mat to measure plantar pressure. The students revisited and reinforced these concepts throughout the educational modules.

          Mr. Robinson explains how to use a goniometer to measure joint range of motion   Mr. Robinson demonstrates to NSLC students how to measure ankle range of motion.   NSLC examines goniometer

    Chris Robinson, CPO, MS, MBA, ATC, FAAOP(D), presented “The Human Foot-Ankle: Anatomy, Range of Motion, and Plantar Pressure Measurement Systems”. He discussed and demonstrated ways that P&O clinicians apply and interpret biometrics. Mr. Robinson taught essential anatomical terms and led NSLC students in movement that exemplified anatomical planes. He demonstrated and instructed the NSCL students to measure their ankle range of motion using a goniometer and their plantar impression using the Harris Beath Mat.

    Mr. Linton, CPO, responds to NSLC questions about his experience using prostheses.Rebecca Stine, MS, manager of the Jesse Brown VA Motion Analysis Research Laboratory, reinforced conceptual information about the biometrics of human biomechanics and gait, showing its application using force plates, digital motion capture, and PEDAR, a digital system to measure plantar pressure. Jeff Linton, a Certified Prosthetist-Orthotist and a prosthesis user, demonstrated gait and Ms. Stine interpreted the images on a 52-inch screen. Mr. Linton answered NSLC students’ questions about the experience of walking and performing other activities of daily living with prosthetic limbs.

    Dr. Wu emphasized that simple devices may be the   NSLC student assists Yeongchi Wu, MD, with dilatancy casting demonstration.  Dr. Wu presented a demonstration of the principles of dilatancy

    Yeongchi Wu, MD, presented an interactive demonstration of “Dilantancy Casting: an Innovative, Sustainable Technology to Provide Cost-Effective Prosthetic Sockets”. Dr. Wu discussed the time, material and economic benefits of using dilatancy casting for prosthetic socket fabrication in comparison to traditional plaster based and CAD-CAM systems. Inviting student participation, he demonstrated the principle of dilatancy casting by applying vacuum to granules contained in a flexible container. Under vacuum, the granules inside the flexible container maintain a rigid form under vacuum. Illustrating the theme, “High Tech, Low Tech, the Right Tech”, Dr. Wu showed how to make a simple upper limb prosthetic device from a soda bottle.  Dr. Wu said, “Simple and inexpensive prosthetic devices that restore essential ADLs to persons with a disability can be more valuable than unattainable expensive, hi-tech devices.”      

    NSLC students learned about prosthetics at NUPOCNSLC students represented every region of the USA and several foreign countries. The majority of NSLC participants plan to pursue college and career tracks in biotechnology and the STEM program at NUPOC opened new possibilities for their future. Many students expressed interest and enthusiasm about possibilities in P&O and rehabilitation engineering.

    R. J. Garrick, PhD, developed and directed this STEM program and everyone at NUPOC contributed to its success. NUPOC appreciates Scheck and Siress for supporting the educational modules in “High Tech, Low Tech, the Right Tech”.

  • Matthew Major, PhD, Presents at VA Research Week
    05/20/2016

    Mattehw Major, PhD, presented his research at VA Research Week (2016)Matthew J. Major, PhD, a VA Career Development Award recipient, delivered a presentation, "Locomotor Stability of Upper and Lower Limb Prosthesis Users", at the Jesse Brown VA Medical Center as part of VA Research Week. His presentation discussed two ongoing VA research projects: 1) the anticipatory and response mechanisms of persons with below-knee limb loss when subjected to a lateral perturbation during walking; and 2) the effects of prosthesis inertial properties on locomotor stability of persons with upper limb amputation. Dr. Major’s presentation was followed by two other Career Development Award recipients whose work investigates therapeutic treatments for alcoholism and obesity.

    05/10/2016

    Suzanne McConn, MS, defends thesisSuzanne McConn, MS, successfully defended her thesis for a Master of Science in Biomedical Engineering. Matthew J. Major, PhD, was her academic advisor. Ms. McConn’s research investigated “Prosthetic Influence on Gait Stability in Individuals with Upper Limb Loss”.

    The study compared subjects’ gait stability in two conditions: 1) when wearing an upper limb prosthesis that matched the mass and inertial characteristics of the sound limb; and 2) when walking without a prosthesis or wearing a prosthesis that did not match the sound limb’s characteristics. Stability during walking was measured using margin of stability, trunk kinematics, average step width, step length and others. Results suggested that wearing a prosthesis with mass and inertial properties that “closely match those of the sound limb may benefit gait stability by reducing transverse trunk rotation” and opened the way to future research in gait stability among individuals with upper limb amputation.
