- Stefania Fatone Participates in Inaugural DoD Review Panel03/16/2015
Stefania Fatone, PhD, BPO(Hons), was invited to participate in the foundational Department of Defense (DoD) FY2014 Clinical and Rehabilitative Medicine Research Program (CRMRP) - Orthotics and Prosthetics Outcomes Research Program (OPORP) Peer Review Panel Meeting held in Reston, VA. The DoD request for proposals challenged the scientific community to address the orthotic and prosthetic treatments and technologies that generate the best patient outcomes. The review panels were comprised of scientists, consumers, biostatisticians, human subject research and technology transfer specialists. The peer review process is designed to support transparency and comprehensive review of proposals seeking DoD funding for innovative and high-impact research.
- NUPOC Welcomes Joel Scham03/13/2015
Joel Scham will conduct research at NUPOC under the supervision of Matthew Major, PhD. To understand the interactions between prosthetic feet and different types of shoe, he will conduct biomechanical testing. He will collect, analyze, interpret, and, together with Dr. Major, publish these data.
In summer 2015, Mr. Scham will complete his Bachelor’s degree in Sport Science with a Biomechanical Engineering focus (University of Konstanz, Germany). His graduation thesis treated a treadmill-based method that he developed to evaluate roll-over shape among able-bodied runners. His prior experience includes working on Biomechatronic Systems projects at Fraunhofer Institute (Stuttgart, Germany) under the direction of Florian Blab, MA, and Felix Starker, Dipl-Ing, the latter of whom was a Visiting Scholar at NUPOC. Mr. Scham’s projects focused on para-cycling and the roll-over shape associated with different running techniques. A licensed mountain bike trainer, in his leisure time, Mr. Scham is an avid bicyclist.
- Dilatancy Research Team Publishes Technical Note03/11/2015
A Technical Note by Larissa (Conner) Sletto, CO, Yeongchi Wu, MD, and Christopher Robinson, CPO, MBA, MS, ATC, FAAOP, “Dilatancy-based Impression and Fabrication Technique for Custom Foot Orthoses”, is published in Prosthetics and Orthotics International (March 11, 2015:1-5. See Prosthetics and Orthotics International Online First where this forthcoming article is published on line prior to print.

- Improving Prostheses for Agricultural Workers03/09/2015
The NIDRR-funded research project, "Assessing and Responding to the Prosthetics Needs of Farmers and Ranchers", is featured in AgrAbility Harvest, 2015:6(1)2-3. The article, "Prosthetics and Agriculture: A Marriage of Necessity", examines the concerns of agricultural workers who use prostheses in their work lives. Derived from interviews with both farmers and prosthetists who serve them, important factors included prosthetic durability, cost, and device adaptability. Research findings showed concerns with cost, sweat and discomfort, insufficient grip force, the inconvenience of myoelectric devices when working in wet conditions, and risks to mobility, stability, and safety when walking over rough terrain. Recommendations for improving prosthetic devices for agricultural workers and others included simplicity, maintainability, durability and affordability.
- NUPOC Announces Dudley S. Childress, PhD Endowment03/05/2015
NUPOC is delighted to announce that the Childress Fund has reached the $100,000 level and Northwestern University will officially endow the Fund in perpetuity as the Dudley S. Childress, PhD Endowment for Research and Education.
Through the generosity of Mrs. Childress, the Childress family, and many other donors, the Dudley S. Childress, PhD Endowment for Research and Education will extend Dudley Childress’ legacy by supporting an annual named program that actively and engagingly introduces Science Technology Engineering Mathematics (STEM) students to rehabilitation engineering.
Dudley Childress, PhD, was a pioneer in biomechanics and rehabilitation engineering, making advances in prosthetic, orthotic, and assistive device technology. His presentations about rehabilitation engineering for prosthetics and orthotics (P&O) inspired students to enter biomedical engineering as a career path. We look forward advancing Dr. Childress’ passion for inspiring and mentoring students through annual STEM programs, thereby expanding the role of engineering in medicine.
NUPOC is deeply grateful to Mrs. Childress, the Childress family, and all donors to the Endowment. Future gifts in honor of Dudley Childress can be made to the Dudley S. Childress, PhD, Fund for Research and Education, thus increasing the value and efficacy of the Endowment.
- Forthcoming Publication about Clinical Validity of Low Cost Accelerometers03/03/2015
NUPOC announces the forthcoming publication by authors Matthew Major, PhD, Pooja Raghavan, MS, and Steven A. Gard, PhD, “Assessing a low-cost accelerometer-based technique to estimate spatial gait parameters of lower-limb prosthesis users”, in Prosthetics and Orthotics International, 2015 (in press). This study examines low-cost accelerometers to estimate step length and distance walked in lower-limb prosthesis users. The system may be a valid and clinically valuable method to characterize prosthetic gait.

- NUPOC Authors Publish Study on Orthotic Management of the Neuropathic Foot01/27/2015
Christopher Robinson, Matthew Major, et al. are authors of “Orthotic Management of the Neuropathic Foot: An Interdisciplinary Care Perspective” published in Prosthetics and Orthotics International, 2015:39(1)73-81. Their article offers a literature review with clinical case studies that elaborate pathologies associated with orthotic management of the neuropathic foot, including ulceration, infection, and Charcot joint arthropathy. To prevent subsequent complications and amputation, authors conclude that clinical care and management of the neuropathic foot should be interdisciplinary, with attention to multiple treatment options.

- NUPOC-International Service Volunteers Ready for Guatemala01/26/2015
NUPOC International Service (NUPOC-IS) volunteers Dylan Borrenpohl, Rae Figueroa, Dan Hallisy, Haris Kafedzic, Brittany Mott, Nicole Olson, Brodie Rice, Jennie Rhodes, Devin Schlueter, Nicholas Uhler, and Kathleen White will provide P&O services to under-served Guatemalans from February 7 through 15 in Zacapa, Guatemala. The 2015 NUPOC-IS team are members of the MPO 2015 cohort who are enrolled in P&O residency training programs. Roberto Lopez-Rosado, DPT, will accompany the team and contribute expertise in physical therapy. Robert Lipschutz, CPO, is the 2015 NUPOC-IS team leader. Volunteers must fund their own transportation and living costs.
Developed and managed by Melinda Thorpe, CO, the NUPOC-IS program collaborates with the Range of Motion Project-Chicago (ROMP) so volunteers can offer their expertise at ROMP’s Kevin O’Halloran Rehabilitation Clinic in Guatemala. Launched in 2009, this collaborative service project formally operates with ROMP under a Northwestern University Memorandum of Understanding (MOU).
Working under the supervision of Robert Lipschutz, CPO, and with ROMP technicians, the NUPOC team will provide P&O clinical services in a stimulating, international setting. Their clients will be low-income Guatemalan adults and children, many of whom travel great distance to receive their first P&O treatment at the ROMP clinic. The NUPOC team will measure and fit assistive devices that enable mobility and independence for their Guatemalan clients. Mr. Lipschutz has volunteered his skills through NUPOC-IS for several years and said, “For me, the greatest reward is seeing the immediate and life-changing empowerment that we can give to the under-resourced Guatemalans who have a physical disability.”

The Childress Fund
The Childress Fund has been established with a generous gift from the Childress family to help carry forward Dudley Childress' work by stimulating interest in rehabilitation engineering for prosthetics-orthotics. Ultimately, the Fund will benefit all who are interested in P&O and especially individuals who live with physical impairments. With your support, the Childress Fund can be endowed in perpetuity. We invite you to be part of this effort by giving generously to the Childress Fund.
