    Dr. Fatone visits Senri Rehabilitation HospitalStefania Fatone, PhD, BPO(Hons), is attending the 17th ISPO World Congress in Kobe, Japan. She is a member of the ISPO Congress’ Scientific Committee. At the conference, Dr. Fatone will chair 3 symposia: Can Orthoses Play a Therapeutic Role in Early Post-Stroke Management?,Growing the Evidence Base in P&O: A Dialogue with the Prosthetics and Orthotics International Editorial Team, and Exploring Quality-of-Care Topics for Users of Custom Ankle-Foot Orthoses; and will present 2 papers: Mechanical Testing of Textured Prosthetic Sockets and Evaluation of Socket Comfort and Functional Performance for Persons with Transfemoral Amputation: Interim Analysis

    While in Japan, Dr. Fatone and several other medical professionals visited Senri Rehabilitation Hospital in Mino City, Osaka. With 172 rehabilitation beds, 7 full time physicians, 7 part time physicians, 62 PTs, 31 OTs, 25 SP, and dozens of other supportive medical care personnel, the hospital is well-known in Japan as a leading facility for rehabilitation following cerebral vascular accident.  

    Masaharu Yoshio, MD, PT, and Vice Director of Senri Rehabilitation Hospital, conducted the informative tour. Dr. Yoshio uses KAFOs for gait retraining in persons recovering from stroke. During the tour, Dr. Fatone attended several talks about the hospital’s unique approach to rehabilitation therapy and observed post stroke patients undergoing gait therapy with KAFOs. 

    The tour organizer was Sumiko Yamamoto, PhD, professor of biomedical engineering, International University of Health and Welfare, Minato, Tokyo, Japan. 

  • Matthew Major Invited Visiting Professor at AIST, Japan

    Matthew Major, PhD, will attend the 17th International Society of Prosthetics and Orthotics (ISPO) in Kobe, Japan, where he will chair the symposium, Stepping Forward: Focusing on Research with the Older Prosthesis User. He also will present two papers, Design and Testing of Passive Prosthetic Feet Optimized Using the Lower Leg Trajectory Error Method Design; and Testing of a Low-Cost, Passive Prosthetic Knee with a Rotary Hydraulic Damper.

    After attending the ISPO Congress, Dr. Major will spend October as Visiting Professor at the National Institute of Advanced Industrial Science and Technology (AIST), the section on Artificial Intelligence Research Center (AIRC) located in Tokyo, Japan. AIST Senior Researcher Hiroaki Hobara, PhD, invited Dr. Major to conduct research at AIST as Visiting Professor.

    Dr. Major will tour AIST laboratories, participate in AIRC activities, serve on a panel to review ISPO Congress outcomes, discuss future collaborative research projects, and provide one-to-one mentoring for Japanese research students. Also, as part of a collaborative project with Dr. Hobara, Dr. Major will collect and analyze human subject data related to the biomechanics of transfemoral prosthesis users during walking and sprinting. During unscheduled time, Dr. Major looks forward to touring museums and other laboratories.

  • Matthew Major Discusses Fall Risk and Fall Prevention

    Matthew Major, PhDToday, the first day of fall, also marks Falls Prevention Awareness Day (FPAD), a nation-wide outreach that raises awareness about how to prevent fall-related injuries among older adults. National, state, and local partners collaborate to educate the public about the health consequences of falls and to advocate for the expansion of evidence-based community fall prevention programs. 

    At NUPOC, Matthew Major, PhD, spearheads research projects that focus on balance and stability, factors that directly affect fall risk and fall prevention among persons with amputation:

    1. Fall Risk and Prosthetic Influence on Gait Biomechanics in Upper Limb Amputees
    2. Lateral Stability and Recovery Strategies among Persons with Below Knee Amputation
    3. Sensory-Motor Mechanisms underlying Fall Risk in Transtibial Amputees

    While Dr. Major’s research is particularly relevant for individuals with an amputation, his findings also have broad application among persons without an amputation.

    Dr. Major discussed the importance of fall prevention research. “Falls are a national epidemic among persons with and without an amputation and especially among the elderly. Falls are a major cause of fatal and debilitating injuries. Even after a person survives a fall, fear of falling may limit daily activities and seriously impair a person’s quality of life. My research about falls aims to develop new knowledge that can result in effective fall prevention modalities for a very large population.”

  • Sub Soo Lim Exhibit Opens at NUPOC Gallery

    Sub Soo Lim Exhibit

    Sub Soo Lim, Korean brush artistAt 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 five Korean ink brush paintings by Sub Soo Lim. Lim says, “My inspiration comes from Nature. I try to capture its energy and spirit.”

    Lim entered university on a full scholarship at age 47, the oldest student on campus. After earning a BFA (Kunsan University) and a MFA (Hongik University) in Korean Painting, Lim opened her own studio and began teaching at her studio and both alma mater. She is widely revered as a master of traditional Korean painting. 

    In 2016, together with her beloved 15-year old dog, Lim moved to the U.S.A. to join her daughter, who also is an artist and a professor of fine art. Successfully navigating linguistic and cultural barriers, Lim steadfastly continues to teach, advance and practice her art at the Milwaukee Institute of Art and Design and the Chicago Korean Cultural Center. 

    Lim says, “It is through art that I find my true self”. Always an active exhibitor, in 2019 Lim presented a solo exhibition at the Chicago Cultural Center and participated in the Women of Wisconsin exhibition. Vigorous and productive at age 80, Lim exercises three times a week, walks her dog daily, and teaches art classes three days a week.  

    Artists and Certified Prosthetist-Orthotists (CPO) cultivate similar skills. Good CPOs must develop a triad of skills: 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. Artists and CPOs also employ creative artistry that bridges science and technology to fit and fabricate functional, comfortable, wearable prostheses and orthoses.

    NUPOC appreciates Sub Soo Lim, Rina Yoon and Ju Sung Kim (deceased) for making this exhibit possible.
