Andrew Sawers, Ph.D., MSPO, is an Assistant Professor in the University of Illinois at Chicago Department of Kinesiology and Nutrition, where he is the director of the Locomotor Rehabilitation Lab. He earned his doctorate in rehabilitation sciences from the University of Washington in 2012 and completed a postdoctoral fellowship in biomedical engineering at Emory University from 2012 to 2015. Dr. Sawers is also a certified prosthetist-orthotist with more than 10 years of clinical experience.


His research program seeks to address three critical areas related to balance and falls among individuals with lower limb amputations: 1) determining who is at risk for a fall (and thus in need of treatment), 2) diagnosing why someone is at risk for a fall (in order to personalize treatment), and 3) predicting how an at-risk individual is likely to fall (in order to prioritize treatment). Rigorous psychometric test development, innovative biomechanical experiments, and robust epidemiological data and statistical modeling are used to achieve these goals. Dr. Sawers has received funding from the National Institutes of Health, U.S. Department of Defense, as well as other national and local foundations to support this research.

Dr. Gregory Dumanian is Chief of Plastic Surgery at Northwestern. He is a surgical innovator who developed Targeted Muscle Reinnervation (TMR) for the treatment of painful nerve endings and for amputees to move bionic limbs. TMR taps into the peripheral nervous system for the information needed to control a myoelectric prosthesis. The nerve signals that used to control the arm are transferred to local otherwise functionless muscles. The larger muscles then amplify the signal, so that the electric impulses can be picked up through the skin by sensors. There is nothing implanted, no wires, and no batteries. Prosthetic function after TMR is smooth, fast, and can occur with much less training.
