- Ryan Caldwell, CP, Awarded the 2020 Carlton Fillauer Prize03/10/2020
Ryan Caldwell, CP, FAAOP, was awarded the 2020 Carlton Fillauer Prize for Outstanding Contribution to Prosthetics Science and Practice. Sponsored by the Fillauer Companies Inc. and awarded every two years by the Orthotic and Prosthetic Education and Research Foundation (OPERF), the prize recognizes an individual prosthetist who has substantially contributed to the practice and understanding of prosthetics through clinical care, research, and publication. The award confers a $5,000 cash prize. Mr. Caldwell received the Carlton Fillauer Prize at the 46th Academy Annual Meeting & Scientific Symposium that convened in Chicago on March 4 through 7.
Mr. Caldwell is a Research Prosthetist at NUPOC and prosthetist at Scheck & Siress. He is well-known as developer of the NU-FlexSIV Prosthetic Socket and is a patent holder of Vacuum Pump Systems for Prosthetic Limbs and Methods of Using the Same (US 20130096694 A1).
Working with NUPOC colleague Stefania Fatone, PhD, BPO(Hons), and others, Mr. Caldwell has contributed actively to major research projects and served as Co-Investigator on Development of Subischial Prosthetic Sockets with Vacuum-Assisted Suspension for Highly Active Persons with Transfemoral Amputations; and Functional Performance Evaluation of the Northwestern University Flexible Sub-Ischial Vacuum (NU-FlexSIV) Socket for Persons with Transfemoral Amputation. He conducts NU-FlexSIV Socket workshops worldwide, teaches Master of Prosthetics and Orthotics students at NUPOC, publishes research outcomes in peer-reviewed journals, and presents his work at professional meetings.
- NUPOC Presents at 49th SWE Career Day for Girls03/04/2020
R. J. Garrick, PhD, and Julia Quinlan, PhD, represented NUPOC as a Biomedical Engineering lab at the 48th Annual Career Day for Girls hosted by the Northwestern University student chapter of the Society of Women Engineers and the Robert R. McCormick School of Engineering and Applied Science. This popular day-long career and educational workshop engages and informs hundreds of girls about engineering careers. The program offers virtual lab tours, hands-on design activities, a keynote talk, and a panel discussion. Do the Impossible is the 2020 Career Day theme.
Dr. Garrick and Dr. Quinlan presented three consecutive virtual lab tours about NUPOC. Dr. Garrick introduced STEM career opportunities in biomedical engineering and the allied health discipline, Prosthetics and Orthotics. She provided an overview of P&O research conducted at NUPOC and discussed some function of orthoses and upper and lower limb prostheses.
Junior high school and high school students and Northwestern University engineering student members of SWE responded eagerly, closely examining a variety of orthoses and prostheses. They manipulated many prosthetic upper and lower limbs, including a demonstration limb that uses electromyographic (EMG) signals for prosthetic control.
Dr. Quinlan summarized her research for the biomedical engineering research project, No Longer Smooth: Introducing Striations into Prosthetic Socket Construction to Improve Suspension, Rotation, Fit and Comfort (Principal Investigator Stefania Fatone, PhD). Participants compared textured socket samples and learned about the longitudinal, rotational, coefficient of friction and tensile strength testing that has preceded research on human subjects.
R. J. Garrick, PhD, developed this interactive virtual lab tour.

Kristin Carnahan, MSPO, CPO, was invited to present a lecture to the Materials Science Engineering department at the Virginia Polytechnic Institute and State University. Ms. Carnahan presented Materials in Prosthetic Applications Following Upper and Lower Limb Amputation to graduate students who are enrolled in the Materials Science Engineering seminar series. In addition to her credentials in Prosthetics and Orthotics, Ms. Carnahan also holds a degree in Chemical Engineering. Virginia Tech Assistant Professor Abby Whittington, PhD, jointly appointed in the MSE and Chemical Engineering departments, extended the speaker invitation to Ms. Carnahan.
The Virginia Tech MSE program emphasizes properties and structure of materials and the appropriate selection of materials for various applications, including fiber optics, pharmaceuticals, oil and gas production, metal casting, semiconductors, cosmetics and many other applications.
While at Virginia Tech, Ms. Carnahan toured the engineering facilities and met with departmental faculty from the departments of Materials Science Engineering, Biomedical Engineering, Industrial Systems Engineering, and Science, Technology, and Society.
- Andrea Sherwood, CPO, MPO, Speaks at NUPOC02/11/2020
Guest Lecturer Andrea Sherwood, CPO, MPO, presented Review of Benefits to Practitioners of Using Good Patient-Practitioner Communication to the MPO Class of 2021. Ms. Sherwood successfully completed a Master of Prosthetics and Orthotics (2015) at NUPOC and currently serves as Area Manager-Upper Midwest, Prosthetics, Össur Americas.
Sherwood said, “Good doctor-patient communication is relevant to good CPO-patient communication and poor communication adversely affects patient outcomes.” She identified five benefits of good CPO-patient communications to P&O clinical practice: 1) lessens the risk of litigation, 2) uses appointment time efficiently and effectively, 3) improves patient outcomes, 4) improves patient satisfaction and increases referrals, and 5) improves practitioner job satisfaction.
Sherwood said, “Communication is the foundation of my clinical practice. Good communication helps me work with patients of diverse backgrounds and enables me to deliver the benefits of my knowledge and skills. Clinical communication is much different than the communication we use with family or friends. As practitioners, we need to alter our communication to fit each patient. We can’t expect patients to conform to our style of communication.”
Sherwood also spoke about the importance of the MPO Capstone Project, a multi-faceted process that matches faculty strengths with students who work to develop a clinically relevant literature review. The Capstone process cultivates students’ research skills, evidence-based reasoning and critical thinking. Sherwood reflected that the Capstone process helped her develop intellectual rigor, critical thinking, problem-solving, goal-setting, and timeliness, skills that are essential in daily clinical practice as a CPO.
Sherwood emphasized the value of faculty mentorship during the Capstone process. Sherwood worked with mentors John Brinkmann, MA, CPO, and Stefania Fatone, PhD, BPO(Hons). Their individualized feedback helped her to refine and improve the Capstone, resulting in a peer-reviewed publication that she co-authored with her mentors, Review of Benefits to Practitioners of Using Good Patient-Practitioner Communication (Journal of Prosthetics and Orthotics, 30(1):5-12, 2018). Ms. Sherwood’s work has received widespread, positive response from practitioners. Sherwood is often invited to present her research findings at professional meetings, hospitals, and webinars.
