The human body has been described as the world’s most complex machine. There are many parts that move both independently as well as in coordinated efforts in order to allow people to perform a variety of activities that healthy individuals take for granted on a daily basis. My work over the past decade has focused on understanding how the human musculoskeletal system works, what happens when one part of the system becomes injured, and then how can we most effectively rehabilitate the body in order to restore normal mechanics. Through this work I have focused on various populations from healthy individuals to patients with various joint pathology including, but not limited to anterior cruciate ligament (ACL) injuries and joint replacements and patients who have sustained metatarsal stress fractures. I have had the privilege of working in and leading large interdisciplinary teams that have included engineers across multiple disciplines, basic scientists, orthopaedic surgeons, and rehabilitation specialists.
Limb symmetry has been examined for decades in an attempt to understand motor control during locomotion. However, one of the most interesting compensatory patterns that develops in pathologic patient populations is a decrease in limb symmetry. In various clinical populations from total joint replacement patients to patients with an ACL reconstruction symmetry is decreased with a shift in loading to the unaffected limb. This lecture will include a discussion of previous work on limb symmetry assessment and the challenges with using some of those methods. With that context, new tools and methods for quantifying discrete limb symmetry in curved data will be presented, with a focus on quantifying limb symmetry during a complex movement such as landing from a jump or during locomotion. These methods are new and, hopefully, this lecture will include dialogue with the audience about the foundations of these methods and their application in engineering and clinical sciences.
Robin Queen served for 11 years as the director of the Michael W. Krzyzewski (Coach K) Human Performance Laboratory at Duke University coming to Virginia Tech in 2015 to helm the Kevin P. Granata Biomechanics Laboratory as an associate professor in biomedical engineering and mechanics. Dr. Queen is also an Associate Professor of Orthopaedic Surgery at the Virginia Tech Carilion School of Medicine, an adjunct faculty at the Edward Via College of Osteopathic Medicine, and an ISCE (Institute for Society, Culture and the Environment) Affiliate. Dr. Queen has an interest in whole body mechanics with an emphasis on loading symmetry and functional outcomes following surgical interventions, and has published more than 100 peer reviewed manuscripts and 3 book chapters. Her work is published in a variety of basic science and clinical journals. Dr. Queen has received numerous honors and awards including being selected as the 2017 recipient of the Kappa Delta Young Investigator Award from the American Academy of Orthopaedic Surgeons. Dr. Queen’s work with professional societies include her roles as chair of the Orthopaedic Research Society’s Women’s Leadership Forum and as a member of the annual meeting and basic science committees. In addition, Dr. Queen serves on the Women’s Health Advisory Board at the American Academy of Orthopaedic Surgery and is as a member of the Medical and Scientific Advisory Board at Quest Diagnostics. Dr. Queen is a Fellow in the American College of Sports Medicine and serves as a member of the Strategic Health Initiative on Youth Sports and Health. In addition, Dr. Queen is the Diversity Chair for the American Society of Biomechanics and serves on the BMES ethics subcommittee. Dr. Queen is passionate about her diversity and inclusion efforts include her previous service to Virginia Tech as the co-chair of the Women’s Alliance, chair of the Biomedical Engineering and Mechanics diversity committee as well as serving as an at-large member of the University’s Commission on Equal Opportunity and Diversity and current service as a member of Gender@VT and a member of the faculty senate at Virginia Tech.
