Anne Silverman will present “Low Back Biomechanics in People with
a Lower-Limb Amputation”


Neuromuscular impairment can result in numerous secondary conditions and mobility deficits. For
example, people with a lower-limb amputation are characterized by asymmetry in movement
kinematics, a greater risk of falling, and a higher prevalence of joint disorders compared to people
without amputations. Secondary conditions such as joint degeneration and pain that develop over
time are likely at least partly due to changes in movement biomechanics after amputation.
Specifically, people with a lower-limb amputation have a high prevalence of low back pain relative
to the general population, which often develops shortly after amputation and has been suggested
to result from altered biomechanics. Using a musculoskeletal modeling and simulation approach,
we have quantified low back kinematics and loading during movements that are important for
mobility and independence. The results of these analyses suggest potential contributing factors to
the degeneration of spinal tissues, which may result in the development of low back pain in this
population over time. This approach can be extended to evaluate prosthetic device interventions
and inform potential targets for movement retraining and rehabilitation.

Dr. Anne Silverman is an Associate Professor in the Department of Mechanical Engineering at the
Colorado School of Mines. She earned her B.S.E. from Arizona State University and M.S.E. and
Ph.D. from The University of Texas at Austin, all in mechanical engineering. Dr. Silverman’s
research program in musculoskeletal biomechanics centers on understanding muscle function to
develop effective treatment and device interventions. As director of the Functional Biomechanics
Laboratory, she uses experimental movement analysis and computational whole-body modeling
techniques to identify functional roles of individual muscles in pathological movement. These tools
are applied to various motions and populations with the goal of improving mobility for people with
disabilities. Her work has been funded by the US National Institutes of Health and the Department
of Defense and has been published in the Journal of Biomechanics, Journal of Biomechanical
Engineering and Gait & Posture. She is active in the American Society of Biomechanics and
currently serves as an Associate Editor for Gait & Posture.
