Research

A major research interest of mine focuses on the effects of lower extremity structural limitations on the mechanics and energetics of locomotion. I use an interdisciplinary approach to my research that draws from three primary areas: biomechanics, exercise physiology, and motor control. Thus, my research philosophy is one that involves a number of research collaborators with expertise in different areas. Research collaborators include Gary Heise, David Hydock, and Carole Schneider from UNC; David Hahn from the Denver Clinic for Extremities at Risk; Cory Christiansen from UC-Denver; Phil Martin from Iowa State University; Brian Umberger from the University of Massachusetts-Amherst; Anne Silverman from Colorado School of Mines; and ChengTu Hsieh at California State University-Chico.

Prosthesis inertia design has progressed substantially over the last decade or two resulting in lower limb prostheses with reduced inertia compared the anatomy theses devices are meant to replace. Prosthesis design continues to progress with a current thrust focusing on the development of more active prosthetic components (e.g., motor-driven prosthetic ankle) to offset functional limitations resulting from lower limb amputations.  Introducing active components to the prosthesis generally increases the inertia characteristics of the limb. My research has focused on understanding the consequences of increasing the inertia of the prosthesis. In addition to this work with amputees, in collaboration with several colleagues we have begun to investigate the functional outcomes following transtibial amputation. Specifically, we are interested in determining whether an osteomyoplastic transtibial amputation has any functional advantages over the more commonly used posterior flap amputation. This project is in the early stages and will be on going for the next few years.

Common side effects of cancer treatments are peripheral neuropathy and vestibular dysfunction. These side effects can lead to a loss of balance in cancer survivors and increase their risk of falling. In collaboration with colleagues in exercise physiology, we have begun to investigate the effects of exercise on mitigating these side effects of cancer treatments. We currently use both a rat model and a human model to answer questions in this area. In the rat model we are investigating the effects of cancer treatments on locomotion patterns to understand the consequences of muscle dysfunction due to cancer treatments. In humans, we have just begun to assess postural steadiness in cancer survivors at various stages of treatment and will be investigating the influence of exercise on improving balance and posture in this population.
