ASME 2012 Summer Bioengineering Conference
Thursday, June 21, 2012 3:00 PM – 4:30 PM
Challenge: UNDERGRADUATE DESIGN COMPETITION IN
REHABILITATIVE AND ASSISTIVE DEVICES
- 6 -
Vieques
Organizers: Lorin Maletsky (University of Kansas), Martin Tanaka (Western Carolina University)
The top six finalist teams in the undergraduate design competition in rehabilitation and assistive
technologies will present their final projects. These six design projects were evaluated and
selected based on a proposal submitted in January, and their presentations will now be judged
to identify the top final project. Funding to help the teams with their projects and travel expenses
was provided by the National Science Foundation.
Challenge: COMPUTATIONAL FLUIDS DYNAMICS CHALLENGE Palominito
Organizers: David A. Steinman (University of Toronto), Francis Loth (University of Akron)
The Challenge centers on a giant cerebral aneurysm with proximal stenosis. This case derives
from a study by Cebral et al. and was chosen for its clinical relevance and because questions
were raised about the CFD predictions. This Challenge aims to test the sensitivity of steady and
pulsatile pressure drops as predicted by different CFD solvers or groups, and against in vitro
pressure measurements. Response to an open call for participation was impressive, with 27
groups from around the world submitting preliminary results spanning a wide range of CFD
approaches. Participants have been blinded to each other's findings and the experimental
results, all of which will be revealed and summarized at the workshop in aggregated form. There
will also be a roundtable discussion about the challenges of holding this Challenge, as well as
plans for further Challenges. Time-permitting, a few participants will briefly introduce their CFD
methods and verification strategies. After the workshop, participants will help draft a manuscript
for submission to the ASME Journal of Biomechanical Engineering.
Challenge: GRAND CHALLENGE COMPETITION TO PREDICT IN
VIVO KNEE LOADS
Icaco
Organizers: B.J. Fregly (University of Florida), Darryl D'Lima (Shiley Center for Orthopaedic
Research & Education at Scripps Clinic)
This annual competition provides the musculoskeletal modeling research community with the
unique opportunity to evaluate its muscle and contact force predictions for the knee. Each year,
experimental movement data collected from a subject implanted with a force-measuring knee
replacement are made available to competitors. Data are collected for gait and other movement
tasks and include surface marker motion, ground reaction force, muscle EMG activity, muscle
strength, CT/MR, and tibial tray contact force. The implant contact force measurements are
withheld for the gait trials, and competitors use musculoskeletal models to predict medial and
lateral contact forces in a blinded fashion for two specified gait trials. The winning team is
selected based on prediction accuracy and modeling novelty and receives a $1000 cash award.
This annual competition is sponsored by the Dynamics, Design, and Rehabilitation Technical
Committee and by the NIH National Institute of Biomedical Imaging and Bioengineering under
grant R01EB009351.
