this research is to promote quantitative standards for socket replacement based on prosthetic fit rather
than duration of prosthesis use, as is current practice.

monitoring of limb volume for maintenance of limb volume/mass"(October, 2010)
The goal of this research is to create a multi-channel bioimpedance analysis system to monitor regional
fluid volume changes in residual limbs of soldiers, veterans, and civilians using prosthetic limbs. Clinical
research studies are conducted to evaluate state-of-the-art volume management devices, and to evaluate
the use of volume feedback control towards enhancing limb fluid volume stability and patient satisfaction.

trans-tibial amputee patients?" (September, 2009)
The Orthotic and Prosthetic Education and Research Foundation (OPERF) is funding a pilot project to use
bioimpedance analysis to model limb volume change in response to variations in socket volume. The
project is intended to generate pilot data to apply for funding a larger study.
Professor Sanders to deliver Science in
Medicine lecture in January, 2015
The Science in Medicine Lecture Series was officially established
in 1976 as a means of recognizing and honoring notable School
of Medicine faculty research achievements and providing an
opportunity for researchers to be apprised of findings outside of
their immediate field. The lecture will take place in January,
2015 at the Magnuson Health Sciences Center on the University
of Washington campus.
