  • Erin Boutwell, PhD, Successfully Defends Dissertation
    06/26/2014

    Erin Boutwell, PhDErin Boutwell, PhD, successfully defended her dissertation, “The Effect of Systematic Variation to Transtibial Prosthesis Stiffness on Impact Loading Mechanics”, in partial fulfillment of the doctoral degree in biomedical engineering.

    Dr. Boutwell's study examined impact forces to residual limbs that can occur when individuals with amputation step with their prosthesis. Her study evaluated reduced-stiffness components in two different loading conditions: an impact drop test (similar to stepping off a curb) and a walking study. Her study examined a systematic variation of the internal spring of a shock-absorbing pylon (i.e., the reduced-stiffness component) over a range of stiffness values to yield information for future design and prescription of reduced-stiffness components.Steven A. Gard, PhD, advised Dr. Boutwell in her study and chaired her doctoral committee.

    Going forward, Dr. Boutwell will conduct research as a post-doctoral fellow at NUPOC.

  • Matthew Major, PhD, Appointed Assistant Professor
    06/16/2014

    Matthew J. Major, PhD has been appointed Assistant Professor of Physical Medicine & Rehabilitation at the Northwestern University Feinberg School of Medicine. Dr. Major will conduct research, advise students and teach courses in Materials Science and Clinical Outcome Measures for the Northwestern University Prosthetics-Orthotics Center (NUPOC) Master's in Prosthetics and Orthotics (MPO) degree program.

  • Matthew Major Garners 5-Year VA Career Development Award
    06/16/2014

    Assistant Professor Matthew J. Major, PhDMatthew J. Major, PhD, was awarded a 5-year Career Development Award from the Department of Veterans Affairs to conduct studies on the sensory-motor mechanisms underlying fall risk in older veterans with lower limb amputation. Although lower limb prosthesis users are known to be at substantially increased fall risk compared to able-bodied individuals, the cause of these falls and the role that sensory-motor mechanisms play in fall risk are poorly understood.

    Dr. Major’s work will focus on identifying modifiable sensory-motor factors of older (65-85 years of age) lower limb prosthesis users to facilitate the development of targeted intervention strategies that can maximize postural control and minimize falls and fall-related injuries. As a Research Health Scientist at the Jesse Brown VA Medical Center, Chicago, IL, Dr. Major will collect and analyze his research data onsite at NUPOC, using the Jesse Brown VA Medical Center Motion Analysis Research Laboratory.  

    The results of Dr. Major’s research will facilitate exploration of therapeutic interventions for improving postural control that may be integrated into the VA system of care, development of clinical diagnostic tools to accurately assess fall risk in older veterans with lower limb amputation, inform VA prescription guidelines of current prostheses, and design future prosthetic devices that enhance functional balance.

    Another facet of Dr. Major’s Career Development Award is participation in formal P&O training, including prosthetic measurement, fabrication, fitting and alignment, as well as mentored training in clinical and translational sciences, amputee clinical care, and motor control theory. This training will complement Dr. Major’s experience and knowledge in biomechanics and prosthetic design, and enable him to develop research initiatives to investigate the functional balance, safety and mobility of assistive device users with neuromuscular and musculoskeletal impairments.

    The original perspective, Partial Foot Amputation May Not Always Be Worth the Risk of Complications, authored by M Dillon, S Fatone, M Morris and published in the Medical Journal of Australia (MJA 200(5), 17 March 2014), has stimulated a lively discussion about the outcomes and benefits of partial foot amputation. This exchange of letters is available online at the Medical Journal of Australia (Med J Aust 2014; 200 (11): 633-637) via the Contents page: https://www.mja.com.au/journal/2014/200/11. Letters were submitted by PE Norman, DE Schoen and L Nedkoff; PA Lazzarini, M Malone and PR Wraight; and MP Dillon, S Fatone and ME Morris.

NUPOC and RIC Offer Free Online Educational Module for Orthotists and Prosthetists

Linda Ehrlich-Jones, PhD, RN, presents Quality Improvement: What Is It and How Do We Use It? 

Northwestern University Prosthetics-Orthotics Center (NUPOC) and the Rehabilitation Institute of Chicago (RIC) offer a free, online educational module for orthotists and prosthetists.

Content includes a description of the benefits of continuous quality improvement efforts and step-by-step instruction on implementing such a project. Quality improvement initiatives have the potential to improve patient service, increase clinician and support staff effectiveness, and minimize cost by continuously identifying areas for targeted improvement. The outcome of such efforts can lead to improved patient satisfaction with clinical services and products, improved function, and, ultimately, improved quality of life.

Dr. Ehrlich-Jones introduces the Orthotics and Prosthetics Users’ Survey (OPUS), which is used to monitor patient functional status, health-related quality of life, and satisfaction with lower-extremity devices and clinical services. OPUS is an instrument that can be used to track patients’ feedback over the course of their treatment by collecting patient data at admission, at device delivery, and again at a later follow-up.

If you have questions or comments regarding the presentation, please contact Lauri Connelly, Clinical Research Coordinator: lconnelly@ric.org or call (312) 238-1405.
