  • Prosthetist Carlos Guamán Visits NUPOC

     Mr. Guamán talks to MPO 2019, Natalia Cardona Malavé interprets, John W. Michael, CPO, moderates.

    Carlos Guamán, prosthetistCarlos Guamán, a clinical prosthetist and P&O educator of Cochabamba, Bolivia, and professional colleague of John W. Michael, CPO, spent several days at NUPOC where he attended informative meetings; reviewed P&O instructional content and fabrication processes; and presented talks about prosthetics and orthotics in Bolivia. Although his English is excellent, Mr. Guamán addressed MPO 2019 in Spanish, allowing Natalia Cardona Malavé (MPO 2019) and José Blankenship to interpret for the student audience. Mr. Guamán has a background in mechanical engineering and he applies the biomechanics of gait to teach his patients how to walk with prostheses. 

    With limited material resources and no public health support for P&O, Mr. Guamán seeks to provide economical clinical care for his clients; also, he pro-actively supplements available training and education to improve standards of local P&O delivery.

    Mr. Guamán explained that amputation in Bolivia is due to trauma, cancer, congenital amelia, or diabetes. Medical care in Bolivia does not offer interdisciplinary, team rehabilitation, so after discharge from hospital, patients must find prosthetic care without assistance and pay for their prostheses without insurance. Mr. Guamán creatively improves his patients’ quality of life by re-purposing available and affordable materials and parts, such as tire rubber, balsa wood, leather and swivel casters intended for office chairs. Mr. Guamán described how to minimize costs by using leather and laces to create transtibial sockets for prostheses, “Soak leather until it is malleable and mold it on a positive cast of the residual limb. When the leather dries, it contracts. Tight lacing achieves suspension on the residual limb."

    Mr. Guamán’s talks inspired NUPOC students who responded positively to the creative and humanitarian P&O care that Mr. Guamán delivers in Bolivia.

  • Stefania Fatone Delivers Keynote at 25th Scientific Meeting of the Japanese Academy of Prosthetists and Orthotists

    Dr. Fatone delivers keynote at JAPO 2018.Stefania Fatone, PhD, BPO(Hons), was invited keynote speaker at the 25th Scientific Meeting of the Japanese Academy of Prosthetists and Orthotists held July 21-22, 2018, in Sapporo, Japan. Dr. Fatone presented The Northwestern University Flexible Sub-Ischial Vacuum (NU-FlexSIV) Socket: Development, Research and Dissemination to a large, interested audience. In the past year, the NU-FlexSIV Socket has attracted great interest in Japan with three sold out workshops held at Kobe College of Medical Welfare and a fourth to be held in January 2019. 

    Satoshi Kojima, conference program chair, and Shin Sasaki, director of the 4-year P&O course at Kobe College of Medical Welfare (Sanda), invited Dr. Fatone to present her work on the NU-FlexSIV Socket. Reflecting the keen national interest in the NU-FlexSIV Socket, six Japanese prosthetists also presented talks about their experiences fitting the NU-FlexSIV Socket.  

    At JAPO, the Kobe College of Medical Welfare booth featured the NU-FlexSIV SocketIn the exhibition hall, the Kobe College of Medical Welfare booth featured the NU-FlexSIV Socket and registered prosthetists for future NU-FlexSIV workshops. Also, two of the first transfemoral amputees in Japan who selectively wear the NU-FlexSIV Socket demonstrated and discussed their experiences with the socket. 

    Other notable international presenters at the JAPO meeting included Dr. M. S. Wong, Hong Kong Polytechnic, who discussed his research on the orthotic management of scoliosis; and British photographer Giles Duley, a triple amputee due to a landmine, who spoke about documenting the experiences of people in conflict zones. 

  • Lenin Delsol Exhibit Opens at NUPOC

    Paintings by Lenin Delsol are on exhibit at the NUPOC Gallery. At NUPOC, science, technology, and art intersect. In recognition of the artistry that is vital to prosthetics and orthotics, NUPOC is delighted to announce the installation and exhibition of oil and watercolor paintings by Lenin Delsol

    Mr. Delsol creatively interprets his figures in a narrative context. Recognized for his attention to draftsmanship and color, he captures his subjects’ features, while also conveying the individuality of their mood and character. In each painting, his use of color and light transforms the human figure into a nearly palpable, sentient person. 

    Born and raised in England, Mr. Delsol and his family moved to Chicago in 1978. As a student at the American Academy of Art (Chicago), Mr. Delsol systematically refined his drawing skills, working first as a comic book artist and illustrator, and later founding his own commercial art studio. Mr. Delsol developed new artistic directions studying under the tutelage of artists Steven Assael, David Leffel, Sherrie McGraw, Burton Silverman, Mary Whyte and Bo Zhang.

    Mr. Delsol is a member of the Oil Painters of America (OPA) and the Portrait Society of America. OPA has selected his work for exhibit at national and regional juried art exhibitions. The National Oil & Acrylic Painters’ Society recognized Mr. Delsol with an Award of Excellence (2015) for his painting, Over the Shoulder, in the online, juried international exhibition. Mr. Delsol instructs and paints at the Palette and Chisel (Chicago), where he serves on the Board of Directors. Approachable and generous, Mr. Delsol supports the development of other artists and often complies with requests to critique works and monitor open studios. 

    Artists and Certified Prosthetist-Orthotists (CPO) cultivate similar skills. A maxim holds that a good prosthetist-orthotist needs the triad of “head, heart, and hands”. Superior cognitive ability, compassion, and hand skills enable CPOs to serve their patients well. As scientists and clinicians, CPOs are rigorously trained in human anatomy, biomechanics, behavioral sciences, professional issues, practice management, and independent research. They also employ creative artistry that bridges science and technology to fit and fabricate functional, comfortable, wearable prostheses and orthoses.

    NUPOC appreciates Lenin Delsol and the Palette and Chisel Academy of Fine Arts (Chicago) for making this exhibit possible.

  • Fatone Contributes to UC Student-Led Design Project

    Stefania Fatone, PhD, BPO(Hons), responded to a request from her former mentee, Angelika Zissimopoulos, PhD, who taught a design engineering class at the University of Chicago. A student team opted to design and improve a tourniquet model in association with Stop the Bleed, a national initiative to educate and empower citizens to reduce mortality from exsanguination among traumatically injured persons. To demonstrate correct tourniquet use, a design goal was to develop a realistic model limb with improved biomimetic compliance and resistance.

    Final model and cross section.

    At NUPOC, Dr. Fatone cast a partial leg of a UC student. The UC student team carried a plaster negative mold to their campus where they fabricated an improved partial leg model using high density foam, Soma Foama® and Dragon Skin®, a high performance silicone rubber. After compression with a tourniquet, the material rebounds to its original form without rupture or distortion. Photo 1 shows the interior structure of the project model. Photo 2 compares the improved, biomimetic leg model to the original leg model that consists of a noncompliant, plastic cylinder. The students filmed a video about their improved model.

    Dr. Zissimopoulos directs initiatives that support STEM teaching and learning at the University of Chicago and teaches an undergraduate course. She completed her doctorate in Biomedical Engineering at Northwestern University, where she conducted research under the mentorship of Dr. Fatone and Steven A. Gard, PhD.
