NUPOC’s robust research collaborations with the VA continue to promote new knowledge that improves health outcomes and quality of life for veterans and others who live with physical impairments.
- Brinkmann Completes Medical Educator Certificate03/01/2021
John Brinkmann, MA, CPO, FAAOP(D), presented his original work, Assessment Criteria for PTB Impressions – A Delphi Study, to mentors and colleagues in the Medical Education Certificate at the Feinberg Academy of Medical Educators.
Assistant Professor John Brinkmann, MA, CPO, FAAOP(D), has completed the Medical Educator Certificate at the Feinberg Academy of Medical Educators (FAME). Brinkmann was accepted into the Medical Educator Certificate (MEC) program for Feinberg faculty instructors in 2016. The development program includes mentorship by FAME leaders and access to an array of tools and opportunities. The program goals are to develop educator skills, recognize teaching excellence, offer new, cross-disciplinary knowledge, and enhance opportunities for collegial networking and collaboration.
Working with FAME mentors, Brinkmann systematically engaged in workshops, lectures and classroom resources that focus on contemporary principles of curriculum design, meaningful feedback, and the measurement of learning outcomes. During the teaching observation requirement, Brinkmann collaborated with Rachel Tappan, MPT, Department of Physical Therapy and Human Movement Sciences. Brinkmann said, “I’ve appreciated the strong emphasis that the FAME faculty place on the interpersonal aspects of education and working together as a team. This process provided insight into how our teaching at NUPOC could be improved in specific ways.”
In partial fulfillment of the MEC, Brinkmann completed a research project involving a novel approach to investigating assessment of a clinical task in prosthetic education. Educators from schools within the US and several foreign countries participated in a Delphi process, which iteratively surveys experts to identify consensus about a topic. He presented his original material as a lecture to his mentors and MEC cohort, Assessment Criteria for PTB Impressions – A Delphi Study (Feinberg Academy of Medical Educators, TIME Lecture: TIME-ly Projects from the Medical Educator Certificate Program, July 16, 2019). Based on this work, Brinkmann and his co-authors have submitted an article for publication in a peer-reviewed journal. “Working with Keirra Falbo, CPO, a 2018 NUPOC MPO graduate, and Sara Morgan, PhD, CPO, a researcher at the University of Washington MPO program, reinforced the importance of collaboration in education and research. This project was a success because of their contributions.”
Brinkmann reflected that his active participation in FAME has enriched his experience as an educator. “I’ve attended TIME lectures and Faculty Development Workshops since I joined the NUPOC faculty, and they have been an important part of my development as an educator. The Medical Educator Certificate program provided a structured opportunity to hear regularly from nationally and internationally recognized medical education experts, including those from within the Northwestern community. Reading peer reviewed articles and listening to podcasts about medical education was a great way to stay up to date with current trends in medical education.”
Brinkman is a strong proponent of life-long education and he builds new knowledge on a strong foundation. He earned his Bachelor of Science degree in Prosthetics & Orthotics (1990) at the School of Allied Health, University of Texas Southwestern Medical Center (Dallas, TX); and completed P&O clinical rotations at Texas Scottish Rite Children’s Hospital, Baylor University Medical Center, and Dallas Rehabilitation Institute. After completing residencies in Iowa and South Carolina, Brinkmann passed his Boards and worked as a clinical CPO and practice manager until 2012 when he joined NUPOC. He holds a MA in theological studies (2007), ethical principles that inform his interactions with students, patients and others. At Northwestern University, Brinkmann was accepted into the 2013-2014 Searle Teaching Fellows Program; and in 2016, he was selected as a John X. Thomas, Jr., PhD, Best Teachers of Feinberg awardee.
Brinkmann has completed and taught numerous continuing education courses in management, clinical techniques and P&O certificate courses offered by the American Academy of Orthotists & Prosthetists (AAOP). He is recognized by AAOP as a Fellow with Distinction and actively contributes to P&O professional journals and societies.
Brinkmann is eager to incorporate his MEC knowledge to further augment didactic methodology at NUPOC. “The NUPOC faculty constantly discuss how to improve our teaching and the content covered in the MEC program is directly relevant to what we do at NUPOC every day. Each element of the Medical Educator Certificate program has helped to further my professional development and supports education objectives within NUPOC and the Department of Physical Medicine and Rehabilitation.”
- Editorial Recaps Editor-in-Chief Contributions to POI02/19/2021
Immediate Past Editors-in-Chief of Prosthetics and Orthotics International Stefania Fatone, PhD, Michael Dillon, PhD, Brian Hafner, PhD, and Nerrolyn Ramstrand, PhD, have published a retrospective editorial that details their initiatives to advance the journal during their term of service.
Highlights of their efforts include editorials in each POI issue that addressed contemporary issues about publishing research data. The editors systematically encouraged excellence in peer review by developing peer-review guidelines; implementing a training process and mentoring for neophyte reviewers; and recognizing the vital contribution of peer reviewers with the 2020 SAGE Elite Reviewer Award. To celebrate the 50th anniversary of the International Society for Prosthetics and Orthotics (ISPO), the editors facilitated a special issue of POI. They also successfully managed the transition of POI to a digital journal and from SAGE to the new publisher, Wolters Kluwer.
During their two-year tenure as Editors-in-Chief, Fatone, Dillon, Hafner and Ramstrand initiated judicious restructuring of manuscript submission, review and selection that has resulted in a corresponding improvement of POI’s content quality, key performance metrics and impact.
- NUPOC Welcomes Nicole Hoffmann, BS02/10/2021
Nicole Hoffmann, BS, has joined NUPOC as a Master’s student in Biomedical Engineering (BME). She will develop her thesis and work under the mentorship of Matthew Major, PhD. In partial fulfillment of her Master’s degree at Northwestern, she will contribute to the research project, Hybrid Electrical-Mechanical Pump for Vacuum Suspension of Prosthetic Sockets. She will conduct structural analysis, human subjects testing of vacuum pump prototypes, and assist in design refinements.
Ms. Hoffmann completed her BS at Northern Illinois University (NIU, DeKalb, IL) in Electrical Engineering with emphases in BME and Applied Mathematics. Her undergraduate research project focused on creating nanoparticles and testing their absorption rate in pancreatic cancer cells. Reflecting her early determination to become and astronaut, her work in nanoparticles and BME reflects her interest in the effects of zero gravity on human physiology. Ms. Hoffmann said, “From childhood, I knew that I wanted to be an astronaut. Nanoparticle research is highly relevant because it can be applied to counteract bone and muscle atrophy in zero gravity.”
As a McKearn Fellow, Presidential Scholar and member of the NIU Honors Program, Ms. Hoffmann was a Research Assistant in the NIU Research Rookies program, where she conducted literature reviews, assisted with lab experiments, wrote proposals and conducted independent research. She also parlayed her scientific skills toward leadership roles. At NIU, she was a Peer Mentor who provided support, review and feedback for student researchers; and she founded the Biomedical Engineering Success Team. In a volunteer capacity, Ms. Hoffmann made time to contribute to the quality of patient care at a community hospital.
Her leisure activities include sky diving at Sky Dive Chicago and piloting aircraft through the Chicago Executive Flight School.
Welcome to NUPOC, Nicole!
- Stefania Fatone, PhD, and Ryan Caldwell, CP, Present at Hanger LIVE02/04/2021
Stefania Fatone, PhD, BPO(Hons), and Ryan Caldwell, CP, were invited to present Transfemoral Socket Design: Northwestern University Sub-ischial Socket Technique as part of the Hanger LIVE virtual meeting held on February 4 and 5.
Mr. Caldwell presented the lecture due to technical issues that prevented Dr. Fatone from joining the session until the post-lecture 30-minute Q&A. Fatone and Caldwell answered questions about what to expect when transitioning patients to the sub-ischial socket, how to deal with adductor rolls, expectations about dynamic alignment, selection of liners and patients that are appropriate for this socket. Time constraints prevented answering many more questions. Questions indicated an active clinical interest in the socket design and a desire for hands-on NU Flex-SIV Socket training. Seventy five participants joined the Fatone and Caldwell educational session.
Throughout the year, Hanger offers their employees on-demand educational courses where clinicians gain new knowledge and continuing education units. To ensure employee participation in Hanger Live, nationwide Hanger Clinics are closed for business during the two day symposium. Hanger plans to provide hands-on NU Flex-SIV Socket training in the post-COVID future.
- Fatone and Collaborative Sensor Research Featured01/22/2021
Professor Stefania Fatone, PhD, BPO(Hons), was Co-Principal Investigator, with McCormick engineers Yongang Huang, PhD, and John Rogers, PhD, (Northwestern University); and Todd Coleman, PhD, (University of California-San Diego), on the research project, Interface Monitoring System to Promote Residual Limb Health.
This project developed a noninvasive, wireless, flexible sensor that applies to the surface of a person’s residual limb and provides continuous monitoring of pressure and temperature within the harsh environment of a prosthetic socket. Dr. Fatone said, “The flexible sensors must adhere to the skin and perform accurately within the socket, where pressure, shear forces, high temperature, humidity and layers of material could potentially disrupt data transmission.” Fatone and the research team tested this novel sensor technology on transtibial and transfemoral subjects. The sensors accurately and continuously transmitted pressure and temperature data. Fatone said, “These initial findings suggest a need for future research in flexible sensor data transfer and potential clinical applications in the field of Prosthetics and Orthotics.”
Findings are published in the research article, Wireless Sensors for Continuous, Multimodal Measurements at the Skin Interface with Lower Limb Prostheses in Science Translational Medicine, 12(574) eabc4327, December 2020. Article co-authors are Kwak JW, Han M, Xie Z, Chung HU, Lee JY, Avila R, Yohay J, Chen X, Liang C, Patel M, Jung I, Kim J, Namkoong M, Kwon K, Guo X, Ogle C, Grande D, Ryu D, Kim DH, Madhvapathy S, Liu C, Yang DS, Park Y, Caldwell R, Banks A, Xu S, Huang Y, Fatone S, Rogers JA.
This collaborative research is featured on the Northwestern Medicine News Center, Novel Device Provides Continuous Monitoring of Skin, Prostheses (Rohman M, January 22, 2021.)
