New NIH Grant: The Sensor (Epidermal Electronic Device)

NIH Grant:

Northwestern University developed a extremely thin electronic device. The resulting 'epidermal' electronic device can be used as a monitoring system, designed to promote residual limb health in persons who wear prostheses, in physical forms that are 'skin like', may demonstrate key technological and scientific advancements towards evidenced-based and person-centered prosthetic care. 

The work involves " Development of 'skin-like' pressure, strain and temperature sensors, with wireless operation, as well as hydration and blood flow sensors. " Development of computational modeling and algorithms for statistical signal processing of the sensor data and pattern recognition to create a user-friendly interface for clinicians and patients. " 



We are very excited about this new NIH Grant. 
Please feel free to contact me with any questions.

OT World Congress, Germany



It was a great honor to be an invited speaker and prosthetic session Chairperson at the  OT World Congress in Leipzig, Germany.  I presented my research on vacuum suspension and socket technology to an audience of industry leaders.  

I specifically presented on the interface between socket and residual limb being crucial to the overall success of the prosthesis user. Improved technology in liners and active vacuum systems allows prosthetists to lower transfemoral socket trim lines without compromising clinical outcomes, and clinical outcomes using a new subischial socket with a vacuum assisted suspension: the NU-FLEXSIV.

"OT World is run by national and international partners from all different sectors of industry and science, as well as service providers.  OTWorld is the most effective platform for sharing research and knowledge as well as current trends and innovations in technology.  Orthotists, prothetists, technicians, therapists, doctors, engineers and funding organizations will all be gathered at the Congress."

It was an honor to represent Northwestern University Department of Physical Medicine and Rehabilitation as well as Scheck and Siress.

THE RANGE OF MOTION PROJECT


The Mission of ROMP is to provide prosthetic limbs and orthotic braces to those who cannot afford or do not have access to these services, empowering them to actively contribute to their families and communities.
ROMP provides prosthetic limbs, orthotic bracing, and training throughout the developing world. Our goals are to:
  • Increase US awareness of the lack of rehabilitative medicine throughout the world.
  • Assemble teams to evaluate and fabricate prosthetic limbs for amputees within Zacapa and other areas with amputees in need throughout the developing world
  • Train local practitioners to pursue ongoing and sustainable services in the communities we work in.
The Vision of ROMP is a more equal distribution of prosthetic and orthotic services throughout the world, facilitating independence through mobility.

ROMP recognizes the hardship of living in poverty without a prosthetic or orthotic device and understands how important these, often times simple devices, are to those who do not have access to them.

In many cases, a prosthetic or orthotic device is a critical component in a disabled person's rehabilitation. With this "tool", independence, mobility and involvement in community and the socio-economic structure can become more attainable. Rehabilitation has the power to increase visibility of the disabled and awareness can change attitudes and help people see that "disability" is only as crippling as the barriers we let stand in our minds and in our world.

Together, with the help of trained prosthetists and orthotists, care givers, volunteers and generous donors, ROMP's vision of offering independence and hope to countless individuals will become a reality.

International Conference: Mallorca, Spain


It was a pleasure to be invited to present at the International Prosthetic Symposium this past June 6-10, 2013. There were speakers from 16 countries represented. I was one of two Americans at the conference. My presentation addressed the liner in trans femoral elevated vacuum socket systems based on a my clinical trial that involved 100 prosthetic wearers. It was a wonderful experience and I learned a lot from fellow physicians and prosthetists in the international prosthetic community.

DoD Grant Receives Additional Funding


Dr. Stefania Fatone Awarded 
Supplemental Funding for Vacuum Pump

In December 2012, Dr.Fatone was awarded supplemental funding through the Joint Warfighter Medical Research Program (JWMRP) to augment and accelerate high priority Department of Defense (DoD) initiatives that imminently will achieve their objectives and yield a benefit to military medicine. This funding will supplement work on the "Development of Subischial Prosthetic Sockets with Vacuum-Assisted Suspension for Highly Active Persons with Transfemoral Amputations."

Vacuum-assisted suspension uses an active pump to create a negative pressure differential between the interior of a prosthetic socket and the surface of a residual limb. The original project developed plans and submitted patent applications for three hybrid, integrated electric/mechanical pump systems that require further development to achieve full maturity and deployment within the military environment. 

The objectives of this supplemental funding are to prototype and test these three hybrid vacuum pumps to create suitable vacuum for prosthesis suspension in highly active persons with transfemoral amputation. Joining Dr. Fatone on this project are NUPOC postdoctoral fellow, Matthew MajorPhD, and NUPOC instrument maker, Dilip Thaker

Sean Wood Defends Master's Thesis at NUPOCSean Wood
August 1 -- Sean Wood defended his master's thesis at NUPOC in the Childress Commons on Monday, August 1, 2011. Mr. Wood is a BS/MS student in mechanical engineering who is working on part of the Department of Defense-funded study at NUPOC, "Development of Subischial Prosthetic Sockets with Vacuum-Assisted Suspension for Highly Active Persons with Transfemoral Amputations." His research was funded by the Department of Defense project, Development of Subischial Prosthetic Sockets with Vacuum-assisted Suspension for Highly Active Persons with Transfemoral Amputations (Principal Investigator Stefania Fatone, PhD).

Mr. Wood's thesis is "Vacuum Pump Characterization and Development." His study identifies options for prosthetic vacuum pumps, characterizes the vacuum pumps that are available, and explores designs that may improve vacuum pump function for military amputees. To characterize the vacuum pumps, researchers evacuated air from chambers with known volumes. These volumes represent the air that must be removed from transfemoral sockets just after donning the prosthesis. After characterizing the pumps, researchers performed similar tests on human subjects to determine the total volume of the socket/liner interface. They compared the time required for evacuation to those obtained from the chambers of known volumes. With the knowledge gained from bench-top testing and human subject testing, researchers explored the issue of vacuum pump design and options to sustain pump activation. Two designs are proposed: 1) a hybrid mechanical/electrical vacuum pump; and 2) an energy harvesting pump.
